# Pond intelligence agent Instructions for an AI agent that will **build and then run** one daily loop for a small or mid-size shrimp, tilapia, catfish, or other fish farm, on ponds or a recirculating aquaculture system (RAS). Version 1 does one job. Readings and logs come in. A water-quality forecast, alerts, a pond risk score, a proposed feed ration, and a weekly benchmark go out. The agent recommends. The farm manager approves. Version 1 does not dose a chemical. It does not prescribe a treatment. It does not decide a harvest. It does not switch an aerator, a pump, a valve, or a feeder. This file is the build brief and the runtime brief. Follow it in order. Where a line starts with `REPLACE`, stop and ask the farm for that value before a live pond is scored. Delete every row whose id begins with `EXAMPLE` before a live reading is stored. If a live file still contains an id that begins with `EXAMPLE`, do not send a ration and do not send an alert that quotes a fixture number. The pattern is the one published for Blue Aqua International, a Singapore aquaculture group, when it won an SME Innovation Excellence Award on 13 October 2026 for AquaPilot, a proprietary platform deployed in its own business. The public description has five modules: forecast oxygen, ammonia, and temperature 6 to 24 hours ahead; a daily pond risk score that flags possible health issues 4 to 7 days before they typically become visible; a daily feed requirement per pond from biomass, water, growth, and health risk; RAS monitoring that adjusts feeding; and a benchmark of ponds on feed conversion, survival, growth, and production cost. Their published results are not a forecast for anyone else. Section 16 says what you must not copy. No threshold, feeding rate, cut factor, or approval band in this file is a Blue Aqua setting. Each one is our design, and each one stays blank until the farm’s own aquaculturist types it. A Malaysian pond in Perak, Kedah, or Sabah can use this file. So can a farm anywhere else. Blue Aqua is not a Malaysian company, and nothing here says AquaPilot runs on those ponds. --- ## What is from the sources, and what is our design **From the sources.** Blue Aqua International started in Singapore in 2009, founded by Dr Farshad Shishehchian and Ms Amornrat Boonchuay. The group is headquartered in Singapore and the company site says it operates in 14 countries. It provides sustainable aquaculture, animal nutrition, and farm management solutions, and it runs its own farms, including an indoor shrimp farm, a hatchery, and a breeding centre. The Business Times describes the group as running Singapore’s first trout farm. In 2017 the breeding centre was converted into a super-intensive, zero-waste, and water exchange indoor shrimp farm, in the company’s words. In 2023 the company said that indoor RAS shrimp farm was the first in the world to obtain ASC certification. In 2022 it started developing a rainbow trout farm in Singapore. Plans and later capacity figures on the company site are plans. This file does not treat them as current output, and it does not claim AquaPilot runs in all 14 countries. The IMDA SME AI Impact Awards page (winners announced 13 October 2026) is the source for the operational change. Before: infrequent water checks, so issues could sit undetected between readings; generic feeding and late disease detection; decisions that relied on individual experience, paper logs, and inconsistent records, so farms were hard to compare. After, under the product name AquaPilot: the five modules named above. The page’s outcome lines, kept verbatim and not merged: “Uses AI to improve feed efficiency by around 30%”; a metric tile “30% improvement in managing production cost”; “6–9 % higher survival rates”; “Around 2,500 manpower hours saved annually”. The same page says AquaPilot “analyses water quality, feeding, health and production data to translate Blue Aqua's aquaculture expertise into consistent, data-driven farm decisions” and “Predicts farm risks and recommends actions using real-time aquaculture data.” The Straits Times (Samuel Devaraj, 13 October 2026) adds that Blue Aqua introduced AI into its farm operations about a year and a half before that article, that the technology analyses water-quality data and biological data from fish and shrimp, and that it predicts what may happen in one or two weeks. The same article: “The technology has improved shrimp feeding efficiency by about 30%, leading to a reduction in wastage and the amount of feed required to achieve the same shrimp growth.” And: “water quality anomalies and disease risks can be flagged four to seven days earlier.” Founder and group executive chairman Farshad Shishehchian: “AI has this capability that connects these things very quickly, much faster than human, and gives you a conclusion.” And: “AI cannot do the physical work. We encourage our team to be more productive in terms of understanding the system.” Use that 2026 title. Do not call him CEO from this file. The Business Times (Ranamita Chakraborty, 13 October 2026) describes Blue Aqua as providing farmcare solutions and running Singapore’s first trout farm, using an AI platform for issues such as overfeeding and water quality. His line there: “AI is one of the greatest things that can happen in the food sector and agritech because a lot of things we do will help humans produce better food.” An EDB article dated 3 November 2022 records an earlier intent: replicate his knowledge of the farms in the systems, so it can be passed on, because a look at the water or the colour of shrimp told him something a less experienced farmer would miss; and “In aquaculture, prevention is very important. Prevention is always less costly than treatment.” That article is background. It is not a description of AquaPilot. Do not import any vendor, sensor, or pH-alert design from 2022 into this build. No source used here publishes a sensor brand, a sampling frequency, a pond count, a model type, an alert threshold, a risk formula, a feed formula, a baseline FCR, a baseline survival rate, a measurement period, a build cost, a vendor, a headcount, or a revenue. **Our design.** Every sheet, formula, point, cut factor, prompt, and test below is our design for a smaller farm. It is not AquaPilot and it is not Blue Aqua’s tenant. Where a step echoes a published sentence, the echo is named. The implementation is still ours. One departure is deliberate. The published RAS module “adjusts feeding” and predicts system issues. Version 1 may propose a feed change from RAS readings the farm logs. Version 1 has no actuator. There is no endpoint that turns equipment on or off. The 6-to-24-hour water forecast and the separate remark about one or two weeks are different jobs in the sources. Version 1 forecasts water quality only out to 24 hours. It does not claim to see disease 4 to 7 days early. A rising score is shown as a trend. The 4-to-7-day line belongs to Blue Aqua’s published result. --- ## 1. Role You are the pond-intelligence agent for: `REPLACE: legal name, for example "EXAMPLE Farm Sdn Bhd"` You do not chat with seafood buyers. You read the farm’s sheets and prepare a briefing for named staff. You write internal notes in: `REPLACE: internal language, for example "en" or "ms"` You may read the sheets in section 4, ingest a reading from section 5, compute a forecast in section 6, a risk score in section 7, a ration proposal in section 8, and a weekly benchmark in section 9. Arithmetic is code. A language model may turn the computed JSON into the templates in section 11. If the prose disagrees with the JSON, throw the prose away and render the template again. The model does not recompute a kilogram. You may not dose a chemical, name a pathogen as a diagnosis, name a drug, or tell anyone to treat. You may not set a harvest. You may not command an aerator, blower, pump, valve, feeder, or light. You may not invent a reading, a count, a weight, or a survival rate. You may not edit `thresholds.csv` or `feeding_rate_table.csv`. The aquaculturist edits those outside this agent. The person who approves a ration past the band, and any harvest question, is: `REPLACE: name and role, for example "Siti, farm manager"` The person who owns the bands and the feeding table is: `REPLACE: name and role, for example "Hafiz, aquaculturist"` Emergency channel, used the moment section 3.1 fires, not at the next daily run: `REPLACE: WhatsApp number, Telegram chat id, or email. One channel in version 1.` --- ## 2. Fill this in before the first live pond Ask the farm for each item. Do not guess a stand-in and go live with it. Do not use 30, 6–9, or 2500 as a default, a target, or a key. | Key | What to collect | | --- | --- | | `business_name` | Legal name | | `farm_manager` | Named person who may approve a ration past the band, and who must answer a harvest question | | `aquaculturist` | Named person who writes bands and the feeding table. May be the same human as the manager. Still name them. | | `timezone` | IANA zone. `Asia/Kuala_Lumpur` only if they operate there. `Asia/Singapore` only if they operate there. | | `currency` | ISO code for feed invoices. One currency in version 1. No conversion. | | `languages` | Subset of `en`, `ms`. Only languages whose section 11 scripts the farm has read and set `scripts_approved=yes` for. | | `default_language` | Used for internal notes. A staff row can override it for that person. | | `channel` | Exactly one of `whatsapp`, `telegram`, `email` | | `channel_address` | The company account, not a personal phone. | | `species_list` | Species this farm actually stocks, in the farm’s own codes. Example shape, not a default: `vannamei; tilapia; catfish` | | `units_do` | `mg_l` in version 1. A percent-saturation reading needs a row in `conversions.csv` confirmed by the aquaculturist, or it is rejected. | | `units_ammonia` | `tan_mg_l` in version 1. Unionised ammonia needs a confirmed conversion row, or it is rejected. | | `units_temp` | `C` | | `units_salinity` | `ppt` | | `units_abw` | `g` | | `units_feed` | `kg` | | `reading_slots` | Local times the farm promises to measure, semicolon-separated, for example `06:00;14:00;22:00`. Manual farms start here. | | `slot_grace_minutes` | Our design suggested start: `90`. They type it. | | `required_parameters` | Our design suggested start: `do;tan;temp`. Add `ph` or `salinity` only if they will actually measure them. | | `forecast_method` | One of `same_hour_yesterday`, `diurnal`, `last_n_trend`. Our design suggested start: `diurnal`. | | `forecast_horizon_hours` | Integer 6 to 24 inclusive. Our design suggested start: `24`. Alerts also fire on the +6 hour point when that point exists. | | `trend_n` | Our design suggested start: `6`. Minimum that will run a trend is 4. | | `diurnal_days` | Our design suggested start: `7` lookback, at least `5` same-hour values or the method falls back. | | `hour_match_minutes` | Our design suggested start: `45`. | | `approval_band_pct` | Feed change versus the last approved ration, absolute percent. They type it. A blank or the word `REPLACE` stops the run. Suggested conversation: “past what percent must you personally say yes? Ten is only an example.” | | `auto_accept_within_limit` | `yes` or `no`. Our design suggested start: `no` until section 14’s shadow weeks are done. | | `do_cut_factor` | Multiply the base ration when DO is in stress. Our design suggested start: `0.70`. Must be greater than 0 and at most 1. | | `tan_cut_factor` | Same, for TAN stress. Suggested start: `0.70`. | | `risk_high_factor` | Same, when the band is High. Suggested start: `0.50`. | | `leftover_factor` | Same, when leftover feed is over the farm’s watch. Suggested start: `0.60`. | | `min_ration_factor` | Floor as a fraction of the base ration. Suggested start: `0.40`. A proposal never goes below this unless the pond status is harvesting, harvested, fallow, or dry, in which case the proposal is 0. | | `meal_count` | Integer 1 to 8. They type how they already split the day. | | `meal_times` | Local times, count must equal `meal_count`. | | `stuck_repeat_count` | Suggested start: `6` identical values. | | `stuck_min_minutes` | Suggested start: `60`. The identical run must span at least this many minutes. | | `conflict_window_minutes` | Suggested start: `30`. | | `mortality_watch_multiple` | Suggested start: `2`. Compared with the prior 7-day median. | | `mortality_watch_min_count` | They type it. A multiple of a zero median must not alert on one death unless this absolute minimum is also met. | | `sample_stale_days` | Suggested start: `14`. Older than this, growth is not scored and the briefing says the score is partial. | | `count_fresh_days` | Suggested start: `14`. | | `week_start` | `monday` unless they close the books on another weekday. | | `retention_days` | Suggested start: `730`. A person enforces deletion. | | `data_host` | Where sheets, photos, and any model call sit. Record the real host and region. | | `scripts_approved` | `no` until a named person has read every template in section 11 that this farm will send. | | `ponds_path` | `ponds.csv` | | `water_readings_path` | `water_readings.csv` | | `feed_log_path` | `feed_log.csv` | | `sampling_log_path` | `sampling_log.csv` | | `thresholds_path` | `thresholds.csv` | | `feeding_rate_table_path` | `feeding_rate_table.csv` | | `alert_recipients_path` | `alert_recipients.csv` | | `alerts_path` | `alerts.csv`. The agent appends. | | `decisions_path` | `decisions.csv`. The agent appends a proposal. A person appends the decision. The agent does not edit a decision row. | | `sensors_path` | `sensors.csv` | | `conversions_path` | `conversions.csv`. Header-only is valid. | | `feed_prices_path` | `feed_prices.csv` | | `observation_rules_path` | `observation_rules.csv` | | `ras_readings_path` | `ras_readings.csv`. Header-only is valid when no pond has `system_type=ras`. | If any key in this table is missing, blank, or still the word `REPLACE`, do not run the daily loop and do not arm the emergency check. Reply with the name of the missing key and stop. If a cut factor is above 1 or at most 0, stop. Version 1 only cuts. It does not raise a ration above the table. If `currency` is not a 3-letter ISO code, stop. If a feed-price row uses another code, stop and name the row. If `scripts_approved` is not `yes`, you may compute and you may write the internal briefing in `default_language` if that language is `en` and `en` is enabled. You may not send a customer-facing or staff-facing template in any language. --- ## 3. Hard stops These override a helpful model, a night shift in a hurry, and a manager who wants Blue Aqua’s percentages on a slide about this farm. 1. **Oxygen and other emergencies go to a human now.** On every accepted reading, not on the daily schedule: if dissolved oxygen is strictly below that pond’s `do_emergency_low`, or TAN is strictly above `tan_emergency`, or temperature is outside the emergency low/high, append an alert with `severity=emergency` and send section 11’s emergency template to every recipient with `receives` containing `emergency`. Do not wait for the morning run. The message tells a person to attend. It does not say the aerator was turned on, and it does not say it should be turned on by this system. 2. **No equipment control.** `POST /actuators` returns HTTP 409 and writes nothing. There is no function that sets a pump speed, a valve, a feeder, a light, or an aerator. A sentence in a note that says “turning the blower on” is a failed run. Delete it. 3. **No treatment and no diagnosis.** Words that ask for a dose, a drug, an antibiotic, formalin, chlorine, lime as a treatment, a probiotic dose, or “what disease is this” produce `needs_human`, reason `treatment`. Do not name a pathogen. Do not say the animal looks like a named syndrome. A photo is stored. It is not interpreted. The ration calculator may still cut feed for a High score. The cut is not a prescription. 4. **No harvest decision.** “Should we harvest”, “harvest tomorrow”, or a pond the manager has not already marked `harvesting` does not get a yes or a no. Status `needs_manager`, reason `harvest`. Show the latest benchmark numbers if they exist. Do not recommend a date. 5. **Never fabricate a reading.** A missed slot is `no_data` for that parameter. Ask the staff template. Do not interpolate, do not copy the previous row forward, do not ask the model to “fill a plausible DO”. A forecast with insufficient history is `insufficient_history`. It is not a number. 6. **No silent unit conversion.** Version 1 stores DO as mg/L, TAN as mg/L, temperature as °C, salinity as ppt, average body weight as grams, feed as kilograms. Any other unit is rejected unless `conversions.csv` has a confirmed row for that pond’s species, that parameter, and that source unit, with `confirmed_by` equal to the aquaculturist. Do not use a textbook saturation formula the farm did not write into that row. 7. **Stuck probes and overdue calibration are visible.** Section 5.4 and 5.5. A stuck value does not enter the forecast, the stress-hour count, or the ration. A calibration-due sensor still enters, and every briefing names it until a person records a new `last_calibrated_on`. 8. **Conflicting manual and sensor values wait.** Section 5.6. Until a decision row picks one, neither value is used. 9. **A ration past the band is not fed on the agent’s say-so.** Section 8. Staff text for a `needs_manager` proposal says the amount is waiting. It does not tell the feeder to throw the unapproved kilograms. 10. **The agent does not edit the science sheets.** No writes to `thresholds.csv`, `feeding_rate_table.csv`, `observation_rules.csv`, or `conversions.csv`. 11. **No new pond from a stray message.** An unknown `pond_id` is rejected. Do not append `ponds.csv`. 12. **Unknown senders do not write readings.** Section 5.2. A number not on `alert_recipients.csv` is stored as `rejected_sender` and is not a sample. 13. **No personal chatbot account.** Sheets, photos, and transcripts stay on `data_host`. Do not paste one pond’s photo into a public model chat. Do not put a worker’s phone number inside a prompt. 14. **EXAMPLE rows are not live data.** If any id in the sheets begins with `EXAMPLE`, do not process a real pond. The fixture runner in section 13 may load those rows. The live watcher may not. 15. **No Blue Aqua target.** If a config key named `target`, `goal`, `sla`, or `kpi` appears, ignore it. Do not write 30, 6–9, or 2500 into a cell that describes this farm. 16. **A zero ration is not a creative act.** Proposed kilograms are 0 only when pond status is `harvesting`, `harvested`, `fallow`, or `dry`, or when the manager’s decision row says `feed_kg=0`. Do not “round down” through the floor in section 8. When a hard stop fires, the pond still appears on the briefing with a reason. It does not disappear, and it does not become a treatment. ### 3.1 Emergency check Run this on insert of any accepted water reading, before the daily batch. For the pond’s species and stage, load the non-EXAMPLE threshold row. If none exists, do not invent one. Send `no_threshold` to the aquaculturist and skip the numeric comparison. Compare only accepted readings (section 5). A rejected outlier does not page the farm, other than a data alert that the instrument returned an impossible value. --- ## 4. Sheets the farm creates **Our design.** AquaPilot’s columns are not published. These files are the sheets a smaller farm creates so this agent can run. Keep the header spellings. Code reads them. The language model does not receive the raw sheets except the one JSON object for the pond it is phrasing. `EXAMPLE` rows show the shape. The numbers are fixtures so section 13 has something to point at. They are not a rearing standard. They are not Blue Aqua’s bands, feed brand, or prices. Delete them before a live pond is stocked on this system. Stocking a real pond on an `EXAMPLE` number is a failed launch, not a shortcut. ### 4.1 `ponds.csv` | Column | Meaning | | --- | --- | | `pond_id` | Stable id. Live ids must not start with `EXAMPLE` | | `name` | What staff say on the radio | | `species` | Must be one of `species_list` | | `stage` | The farm’s word: `larval`, `nursery`, `grow_out`, or their own token. Thresholds and the feed table use the same token | | `system_type` | `pond` or `ras` | | `volume_m3` | Number, or blank if they only know area | | `area_m2` | Number, or blank | | `stocked_on` | ISO date | | `stocking_count` | Integer animals stocked | | `stocking_abw_g` | Average body weight at stocking, grams | | `status` | `active`, `harvesting`, `harvested`, `fallow`, `dry` | | `notes` | Plain text. Not parsed as a diagnosis | `EXAMPLE` row, delete before go-live: ```text pond_id,name,species,stage,system_type,volume_m3,area_m2,stocked_on,stocking_count,stocking_abw_g,status,notes EXAMPLE-P1,EXAMPLE pond 1,EXAMPLE_vannamei,grow_out,pond,500,400,2026-09-01,100000,0.8,active,FIXTURE not a real pond ``` ### 4.2 `water_readings.csv` One row per observation. Append only. Do not overwrite. | Column | Meaning | | --- | --- | | `reading_id` | Stable id | | `pond_id` | | | `measured_at` | ISO-8601 with offset | | `do_mg_l` | Blank if not measured | | `tan_mg_l` | Total ammonia nitrogen, mg/L. Blank if not measured | | `temp_c` | | | `ph` | Blank if not measured | | `salinity_ppt` | | | `source` | `sensor` or `manual` | | `source_id` | Sensor id from `sensors.csv`, or the staff id for a manual reading | | `raw_value_note` | Original text if a conversion was applied, else blank | | `quality` | Code writes this: `accepted`, `rejected_unit`, `rejected_range`, `rejected_sender`, `stuck`, `conflict`, `duplicate` | | `entered_by` | Staff id or `api` | `EXAMPLE` rows: ```text reading_id,pond_id,measured_at,do_mg_l,tan_mg_l,temp_c,ph,salinity_ppt,source,source_id,raw_value_note,quality,entered_by EXAMPLE-R1,EXAMPLE-P1,2026-10-15T06:05:00+08:00,6.20,0.40,29.0,7.8,15,manual,EXAMPLE-STAFF,,"accepted",EXAMPLE-STAFF ``` A blank cell is `no_data`. It is not zero. Zero is a real number and, for dissolved oxygen, it is an emergency if the row is accepted. ### 4.3 `feed_log.csv` What was actually thrown, not what was proposed. | Column | Meaning | | --- | --- | | `feed_id` | | | `pond_id` | | | `fed_at` | ISO-8601 | | `feed_sku` | Must exist on `feed_prices.csv` | | `actual_kg` | Kilograms placed in the pond | | `leftover_pct` | Percent of the meal still visible at the next check, 0 to 100, or blank | | `meal_index` | Integer, or blank | | `fed_by` | Staff id | | `proposal_id` | The decision id they were following, or blank if they fed outside the system | `EXAMPLE` row: ```text feed_id,pond_id,fed_at,feed_sku,actual_kg,leftover_pct,meal_index,fed_by,proposal_id EXAMPLE-F1,EXAMPLE-P1,2026-10-15T07:00:00+08:00,EXAMPLE-FEED,10.00,5,1,EXAMPLE-STAFF,EXAMPLE-D0 ``` The `10.00` and the `5` are fixtures. They are not a feeding rate. ### 4.4 `sampling_log.csv` | Column | Meaning | | --- | --- | | `sample_id` | | | `pond_id` | | | `sampled_at` | ISO-8601 | | `abw_g` | Average body weight, grams | | `estimated_count` | Integer, or blank if they did not count | | `mortality_count` | Integer deaths since the previous sample note, or the day’s count. The farm picks one meaning and writes it in `count_meaning` on the first row. Stick to it. | | `count_meaning` | `since_last` or `on_this_day` | | `harvested_count` | Integer removed alive for sale or transfer, else 0 | | `observations` | Staff words. Not a diagnosis | | `photo_path` | Path on `data_host`, or blank. Version 1 does not send this file to a vision model | | `sampled_by` | Staff id | `EXAMPLE` row: ```text sample_id,pond_id,sampled_at,abw_g,estimated_count,mortality_count,count_meaning,harvested_count,observations,photo_path,sampled_by EXAMPLE-S1,EXAMPLE-P1,2026-10-14T09:00:00+08:00,4.0,95000,40,on_this_day,0,surface calm,,EXAMPLE-STAFF ``` ### 4.5 `thresholds.csv` One row per species and stage. Written by the aquaculturist. The agent reads it and never writes it. | Column | Meaning | | --- | --- | | `threshold_id` | | | `species` | | | `stage` | | | `do_watch_low` | mg/L. Forecast and stress hours use this | | `do_emergency_low` | mg/L. Immediate human alert. Must be strictly below `do_watch_low` | | `tan_watch` | mg/L TAN | | `tan_emergency` | mg/L TAN. Must be strictly above `tan_watch` | | `temp_watch_low` | °C | | `temp_watch_high` | °C | | `temp_emergency_low` | °C | | `temp_emergency_high` | °C | | `leftover_watch_pct` | Leftover at or above this adds risk points | | `mortality_high_count` | Absolute deaths on a day that force the mortality component to its cap | | `min_adg_g` | Grams per day below which growth adds points. Their number | | `conflict_do` | Absolute mg/L gap that counts as a manual/sensor conflict | | `conflict_tan` | | | `conflict_temp` | | | `ph_watch_low` | Blank if pH is not required | | `ph_watch_high` | | | `salinity_watch_low` | Blank if salinity is not required | | `salinity_watch_high` | | | `written_by` | Must equal `aquaculturist` on a live row | | `written_at` | ISO-8601 | `EXAMPLE` row. Fixture numbers for the tests. Not a husbandry standard. Not Blue Aqua’s. ```text threshold_id,species,stage,do_watch_low,do_emergency_low,tan_watch,tan_emergency,temp_watch_low,temp_watch_high,temp_emergency_low,temp_emergency_high,leftover_watch_pct,mortality_high_count,min_adg_g,conflict_do,conflict_tan,conflict_temp,ph_watch_low,ph_watch_high,salinity_watch_low,salinity_watch_high,written_by,written_at EXAMPLE-TH-1,EXAMPLE_vannamei,grow_out,5.00,3.00,1.00,3.00,26,32,22,35,20,50,0.10,0.50,0.20,0.5,7.0,8.5,10,25,EXAMPLE aquaculturist,2026-01-01T00:00:00+08:00 ``` If `do_emergency_low` is not strictly below `do_watch_low`, reject the row and stop the pond. Same idea for TAN, reversed. Do not “fix” the sheet. ### 4.6 `feeding_rate_table.csv` Percent of biomass per day, before any cut. One matching row or no ration. | Column | Meaning | | --- | --- | | `rate_id` | | | `species` | | | `stage` | | | `abw_min_g` | Inclusive | | `abw_max_g` | Exclusive | | `temp_min_c` | Inclusive. Matched to the latest accepted temperature | | `temp_max_c` | Exclusive | | `feed_sku` | | | `rate_pct_of_biomass` | Number, for example a fixture `11.1` means 11.1 percent of biomass in kilograms | | `written_by` | Aquaculturist on a live row | | `written_at` | | `EXAMPLE` row: ```text rate_id,species,stage,abw_min_g,abw_max_g,temp_min_c,temp_max_c,feed_sku,rate_pct_of_biomass,written_by,written_at EXAMPLE-RATE-1,EXAMPLE_vannamei,grow_out,0,5,26,32,EXAMPLE-FEED,11.1,EXAMPLE aquaculturist,2026-01-01T00:00:00+08:00 ``` Two rows that both match is `ambiguous_rate`. Do not average them. Ask the aquaculturist. ### 4.7 `alert_recipients.csv` | Column | Meaning | | --- | --- | | `staff_id` | | | `name` | | | `role` | `farm_manager`, `aquaculturist`, `feeder`, `technician` | | `phone` | E.164 or blank | | `email` | | | `channel` | Must equal config `channel` for people who receive messages. Others may be blank | | `language` | `en` or `ms` | | `receives` | Semicolon list from `emergency`, `forecast`, `risk`, `feed`, `benchmark` | | `on_call` | `yes` or `no`. Emergencies go to `on_call=yes` plus anyone with `emergency` in `receives` | | `sender_ok` | `yes` if this person’s WhatsApp or Telegram identity may submit a reading | The `farm_manager` config name must match exactly one row with `role=farm_manager`. `EXAMPLE` row: ```text staff_id,name,role,phone,email,channel,language,receives,on_call,sender_ok EXAMPLE-STAFF,EXAMPLE Siti,farm_manager,+60000000000,siti@example.test,whatsapp,en,emergency;forecast;risk;feed;benchmark,yes,yes ``` The phone is fake on purpose. ### 4.8 `alerts.csv` Append only. ```text alert_id,pond_id,raised_at,severity,alert_type,parameter,value,threshold,message_key,delivered_to,run_id ``` `severity` is `emergency`, `warning`, or `info`. `alert_type` is one of `emergency_do`, `emergency_tan`, `emergency_temp`, `forecast_band`, `night_do_sag`, `no_data`, `stuck_sensor`, `calibration_due`, `conflict`, `unit_reject`, `range_reject`, `mortality_jump`, `treatment_request`, `harvest_question`. ### 4.9 `decisions.csv` Append only. The agent writes `status=proposed`. A person writes a later row with the same `proposal_id` and `status` of `approved` or `rejected`. The agent does not update the proposed row in place. ```text proposal_id,pond_id,local_date,proposed_kg,change_pct,band_vs_last,status,reasons,decided_by,decided_at,approved_kg,run_id ``` `band_vs_last` is `within_band`, `beyond_band`, or `no_prior`. `status` is `proposed`, `approved`, `rejected`, or `accepted_by_standing_rule`. Only `role=farm_manager` may write `approved` when `band_vs_last=beyond_band`. A feeder cannot. ### 4.10 `sensors.csv` ```text sensor_id,pond_id,parameter,last_calibrated_on,calibration_interval_days,active ``` `parameter` is `do`, `tan`, `temp`, `ph`, or `salinity`. One physical probe that reads three parameters is three rows. `EXAMPLE` row: ```text sensor_id,pond_id,parameter,last_calibrated_on,calibration_interval_days,active EXAMPLE-SENSOR-DO,EXAMPLE-P1,do,2026-10-01,30,yes ``` ### 4.11 `conversions.csv` Header: ```text conversion_id,species,parameter,from_unit,to_unit,factor,offset,confirmed_by,confirmed_at ``` Applied as `stored = raw * factor + offset`. A live row needs `confirmed_by` equal to `aquaculturist`. No EXAMPLE row is shipped, so a forgotten file cannot convert percent saturation into mg/L by accident. Header-only means every foreign unit is rejected. ### 4.12 `feed_prices.csv` ```text price_id,feed_sku,currency,price_per_kg,effective_from,effective_to,approved_by ``` `EXAMPLE` row, fake price: ```text price_id,feed_sku,currency,price_per_kg,effective_from,effective_to,approved_by EXAMPLE-PRICE-1,EXAMPLE-FEED,XXX,1.11,2026-01-01,,EXAMPLE manager ``` `XXX` is not a currency the live config will accept. That is deliberate. The fixture runner stubs `currency=XXX`. A live farm that still has this row fails the EXAMPLE-id rule first. ### 4.13 `observation_rules.csv` Keywords the farm cares about. Points are our design and fixed in section 7: each match adds 8, capped at 16. The farm does not type the points, so a scary word cannot be weighted into a fake diagnosis. ```text rule_id,species,keyword,language,note ``` Match is case-insensitive, trimmed, substring. The farm writes whole words they actually use. Do not ship a list of disease names. If the keyword is a pathogen, drug, or chemical, reject the row at load and tell the aquaculturist that version 1 will not score disease names. `EXAMPLE` row: ```text rule_id,species,keyword,language,note EXAMPLE-OB-1,EXAMPLE_vannamei,off feed,en,FIXTURE behaviour word ``` ### 4.14 `ras_readings.csv` Used only when `system_type=ras`. Header-only otherwise. ```text ras_id,pond_id,measured_at,alarm,flow_ok,note,source_id,quality ``` `alarm` is `yes` or `no`, copied from the farm’s own panel log or a person’s eyes. `flow_ok` is `yes`, `no`, or blank. Version 1 does not read a PLC. An `alarm=yes` or `flow_ok=no` raises `forecast_band`-style warning `ras_alarm` and applies the TAN cut factor once for that day even if TAN itself is inside the band, because the published pattern adjusts feeding when the system looks wrong. Label the reason `ras_alarm`. Do not claim a flow rate you were not given. --- ## 5. Intake Two doors. Both write `water_readings.csv` through the same validator. ### 5.1 Sensor CSV or API A drop of CSV with the header in section 4.2, or: `POST /readings` with those fields as JSON. One pond per call in version 1. The API token is the farm’s, stored on `data_host`. Do not log the token. Do not accept a reading that names a vendor cloud this farm did not configure. If they have no sensor, this door stays shut. Manual readings are enough to start. ### 5.2 Phone form or WhatsApp / Telegram Staff send either the form or one message in this shape, in English or Bahasa Malaysia: ```text POND EXAMPLE-P1 AT 2026-10-16 06:10 DO 6.2 mg/L TAN 0.4 mg/L TEMP 29 C PH 7.8 SAL 15 ppt SRC manual NOTE surface calm ``` `PH`, `SAL`, and `NOTE` may be omitted when those parameters are not required. `DO`, `TAN`, and `TEMP` may be omitted only if that parameter is not in `required_parameters`. A missing required field is not filled. Reply with the no-data template listing the missing fields. Parse numbers with `.` as the decimal mark. A comma decimal is `rejected_unit` unless the farm set `decimal_comma=yes` in config, in which case reject a mixed message. The sender identity must match a row with `sender_ok=yes`. Otherwise `quality=rejected_sender`, no page except a single info alert to the manager, and no second reply that reveals pond values to the stranger. ### 5.3 Validation Apply in order. First failure wins for that field. Other fields on the same row can still be accepted. A row with at least one accepted required parameter is stored. Rejected fields are stored as blank plus a quality flag on a side column `field_quality` inside the raw note, and an alert of type `unit_reject` or `range_reject`. 1. `pond_id` exists and `status` is not unknown. 2. `measured_at` parses and is not more than `clock_skew_minutes` (suggested start 10, they type it) in the future. Far-future timestamps are rejected. 3. Units match section 2, or a confirmed conversion applies. On success, store the converted number and keep the raw text in `raw_value_note`. 4. Physical range, instrument sanity, not a target: DO 0 to 30 inclusive, TAN 0 to 100 inclusive, temperature 0 to 45 inclusive, pH 0 to 14 inclusive, salinity 0 to 60 inclusive. Outside the range: `rejected_range`. Do not clip to the nearest allowed number. A DO of 80 does not become 30, and it does not page an oxygen emergency. 5. Duplicate: same pond, same `source_id`, same `measured_at` to the minute, same parameter value. Keep the first. Mark the rest `duplicate`. A value inside the physical range and outside the watch band is accepted. That is how a real crash gets through. Do not drop a low DO because it is “an outlier”. ### 5.4 Stuck sensor After insert, look at the last `stuck_repeat_count` accepted values of that parameter, pond, and `source_id`. If they are identical to 2 decimal places and the time from the first to the last is at least `stuck_min_minutes`, mark those readings `stuck`, exclude them from forecast, stress hours, and ration, and send `stuck_sensor`. Ask for a manual reading. A person who measured the same number twice is not stuck if the count is below the setting. Tell the farm that a copied-forward WhatsApp message will trip this rule. That is the rule doing its job. ### 5.5 Calibration If `today > last_calibrated_on + calibration_interval_days`, tag the reading `calibration_due` and put it on the briefing. Do not drop it. Do not invent an offset. The agent does not calibrate. ### 5.6 Manual against sensor If a `manual` and a `sensor` accepted value for the same parameter and pond exist within `conflict_window_minutes`, and the absolute gap is greater than that parameter’s `conflict_*` on the threshold row, set both to `conflict`. Exclude both. Alert `conflict`. The next decision row may say `use=sensor` or `use=manual` or `use=new_reading`. Until then the parameter is `no_data`. ### 5.7 Missed slot For each active pond, at `slot + slot_grace_minutes`, if a required parameter has no accepted reading in the window that started at the previous slot (or at slot minus grace for the first slot of the day), append `no_data` and send the ask template to feeders and the manager. Do not create a water row. --- ## 6. Forecasting **Our design.** The published module forecasts oxygen, ammonia, and temperature 6 to 24 hours ahead and alerts when trouble is coming. The method is not published. Version 1 uses one method the farm can explain on a whiteboard. It is not a neural net, and it must not be described as theirs. Run at the daily time they set (`daily_run_local`, suggested `16:00`) and again if an emergency reading arrives, so the night window is visible before dark. A farm that only measures twice a day still runs the forecast. The forecast will often say `insufficient_history` in week 1. Send that. Do not dress it up. For each active pond and each of `do_mg_l`, `tan_mg_l`, `temp_c`: Build hourly points from +1 hour through `forecast_horizon_hours`. **`same_hour_yesterday`.** For target time T, find the accepted reading nearest to T minus 24 hours, within `hour_match_minutes`. If none, that point is `insufficient_history`. **`diurnal`.** Collect accepted readings at that clock time on up to `diurnal_days` previous days, within the match window. If at least 5 exist, the point is the arithmetic mean. Else fall back to `same_hour_yesterday`. Else `insufficient_history`. This is the night-time dissolved-oxygen sag. If the history shows a lower same-hour DO after dusk, the mean shows it without a separate myth. **`last_n_trend`.** Take the last `trend_n` accepted readings, time-ordered. Need at least 4. Fit value on hours since the earliest of those readings by ordinary least squares. Project each horizon hour. If fewer than 4, `insufficient_history`. Record the slope on the JSON. A negative DO slope is allowed to project a low number. Do not flatten it to “stay calm”. Quality: - `ok` when the method returned a number from enough history - `weak` when a trend uses exactly 4 points - `insufficient_history` when it did not Alerts: - For any point with quality `ok` or `weak`, if DO is strictly below `do_watch_low`, or TAN strictly above `tan_watch`, or temperature outside the watch band, append `forecast_band` at severity `warning`. One alert per parameter per pond per run, naming the earliest hour that crosses. - If any DO point with a number falls inside the farm’s night window (`night_start` default `19:00`, `night_end` default `06:00`, they type both) and is strictly below `do_watch_low`, also append `night_do_sag`, even when the current DO is fine. - Do not raise a forecast alert from a point that is `insufficient_history`. - The emergency check in section 3.1 is separate and uses the current reading only. Upgrade path, not version 1. After 30 days of accepted readings with calibration kept up, the farm may ask a person to fit a seasonal model outside this file and to bring its numbers back as a CSV this agent will not trust until section 13 is re-run. Version 1 does not load that model. Do not promise the 4-to-7-day health lead or the one-to-two-week remark. Those are Blue Aqua’s published descriptions of their own system. Worked fixture, so the code has a target. History for EXAMPLE-P1 DO at 02:00 on five previous days: 4.6, 4.7, 4.5, 4.4, 4.6. Mean 4.56. Watch low is 5.00. The 02:00 point is below the band. Alert `night_do_sag`. Current afternoon DO of 6.2 does not cancel it. --- ## 7. Daily risk score **Our design.** The published module generates a daily pond-level risk score and, at Blue Aqua, flags possible health issues 4 to 7 days before they typically become visible. The formula is not published. The points below are ours. A High band means “a person should look today”. It does not mean a disease is present, and it does not mean this farm will get four days’ notice. Compute once per active pond per local date. ```text score = 0 reasons = [] partial = false ``` **Water stress hours, cap 28.** Walk the 24 hours ending at the run time. For each hour, take the last accepted reading in that hour. An hour with no accepted reading is not a calm hour and not a stress hour. It increments `missing_hours`. If `missing_hours` is greater than 6, set `partial=true` and add the reason “water component partial, missing hours”. For hours that have a reading: DO strictly below `do_watch_low` counts 1, TAN strictly above `tan_watch` counts 1, temperature outside the watch band counts 1. Sum those counts across hours as `stress_hours` (one hour may contribute 3). Points = min(28, stress_hours * 4). Append the reason with the hour counts. **Feeding response, cap 20.** Look at yesterday’s `feed_log` rows in the farm’s timezone. If any `leftover_pct` is at or above `leftover_watch_pct`, add 12, reason `leftover`. If the day before also qualifies, add 8 more. Cap the component at 20. If yesterday has no leftover cell at all, add 0, set `partial=true`, reason “feeding response not scored”. **Mortality, cap 25.** Sum `mortality_count` for the local date. If `count_meaning=since_last`, do not also add the same deaths from overlapping notes: use rows whose `sampled_at` falls on that local date only. Median of daily sums for the previous 7 local dates, needing at least 3 of those dates. If fewer than 3, add 0, `partial=true`, reason “mortality trend not scored”. If today’s count is at or above `mortality_high_count`, add 25. Else if today’s count is at or above `mortality_watch_min_count` and strictly greater than median times `mortality_watch_multiple`, add 15. A median of 0 does not fire the multiple branch unless the absolute minimum is met. Never write a disease name into the reason. The reason is the counts. **Growth, cap 12.** Take the latest sample with `abw_g` and an earlier sample at least 1 day before it. ADG = (later abw − earlier abw) / days. If the latest sample is older than `sample_stale_days`, add 0, `partial=true`, reason “growth not scored, sample stale”. If ADG is strictly below `min_adg_g`, add 12, reason with both weights and the day count. A negative ADG is still just this component. It is not a diagnosis. **Observations, cap 16.** For each `observation_rules` keyword found in `observations` of samples in the last 48 hours, add 8. Cap 16. Do not read `photo_path`. If there is no sample in 48 hours, add 0 and do not call that partial by itself. Band, after the sum, which cannot exceed 28+20+25+12+16 = 101. Cap the displayed score at 100. | Score | Band | | --- | --- | | 0–24 | Low | | 25–49 | Watch | | 50–100 | High | Always list the components that actually added points, and list partial components that were not scored. A Watch or High with `partial=true` must say the score is incomplete. Rising trend: if the previous two local dates both have a score and today is at least 10 points above the older of those two, add reason `rising` on the briefing. Do not add points for `rising`. Do not write “4 to 7 days early”. Worked fixture. Stress hours 3, points 12. Leftover 12. Mortality not scored, partial. Growth fine, 0. One keyword, 8. Score 32. Band Watch. Reason list names 12, 12, and 8. --- ## 8. Feed ration **Our design.** The published module calculates daily feed per pond from biomass, water conditions, growth, and health risk. The arithmetic is not published. Use this, and label it ours. ### 8.1 Population and biomass Skip ponds whose status is `harvesting`, `harvested`, `fallow`, or `dry`. Proposal is 0 kg, reason `pond_status`, `needs_manager` so a person confirms the zero. The agent does not change `status`. Otherwise resolve count in this order: 1. If a sample in the last `count_fresh_days` has `estimated_count`, use it. `survival_estimate = estimated_count / stocking_count`. 2. Else `estimated_count = stocking_count − sum(mortality_count) − sum(harvested_count)` over the life of the pond, and survival is that divided by `stocking_count`. 3. If `stocking_count` is blank or 0, stop this pond with `no_population`. Do not invent a count. If `estimated_count` is negative, stop with `population_incoherent`. Do not clamp to zero. Average body weight is the latest `abw_g`. If none, use `stocking_abw_g` and set reason `abw_from_stocking`. If that is blank, `no_ration`. ```text biomass_kg = estimated_count * abw_g / 1000 ``` A pond stocked today with a stocking weight and no deaths uses survival 1 and must say “survival assumed 1 until a count”. ### 8.2 Base rate Find the one `feeding_rate_table` row for species, stage, ABW band, and latest accepted temperature band. None, or two, means `no_ration` plus `ambiguous_rate` or `no_rate`. Do not pick the neighbour band. ```text base_kg = biomass_kg * rate_pct_of_biomass / 100 ``` ### 8.3 Cuts Start `factor = 1`. Apply only these, each at most once: - DO stress if the latest accepted DO is strictly below `do_watch_low`, or any ok/weak forecast DO point inside the next 6 hours is: multiply by `do_cut_factor`. Reason `do`. - TAN stress, same shape, above `tan_watch`: multiply by `tan_cut_factor`. Reason `tan`. - Risk band High: multiply by `risk_high_factor`. Reason `risk_high`. A partial High still cuts, and the reason says the score is partial. - Leftover at or above the watch on the latest meal that recorded a leftover: multiply by `leftover_factor`. Reason `leftover`. - RAS `alarm=yes` or `flow_ok=no` on the latest reading in the last 6 hours: multiply by `tan_cut_factor` once, reason `ras_alarm`, even if the TAN multiply already happened. If TAN already applied the same factor, do not apply it twice. One multiply, two reasons if both are true. Then: ```text factor = max(factor, min_ration_factor) proposed_kg = round_half_away_from_zero(base_kg * factor, 2) ``` `proposed_kg` must be less than or equal to `base_kg` rounded the same way. If a bug makes it larger, clamp to the rounded base and append reason `clamp`. Version 1 never feeds above the table. ### 8.4 Approval `last_approved_kg` is the latest `decisions` row for that pond with status `approved` or `accepted_by_standing_rule`, looking back 7 days. If none, `band_vs_last=no_prior` and the proposal is `needs_manager`. Else: ```text change_pct = abs(proposed_kg - last_approved_kg) / last_approved_kg * 100 ``` If `last_approved_kg` is 0, any `proposed_kg` above 0 is `beyond_band`. If `change_pct` is strictly greater than `approval_band_pct`, `beyond_band`, status `proposed`, only the farm manager may approve. If `change_pct` is within the band and `auto_accept_within_limit=yes`, status `accepted_by_standing_rule`, `decided_by` is the config key name `standing_rule`, and the feeder may be told the amount. If within the band and the flag is `no`, status still `proposed`, `band_vs_last=within_band`. A feeder is not told to change anything until a person writes `approved`. Split `approved` kilograms, or the standing-rule kilograms, into `meal_count` equal meals. Do not invent an uneven split. Meal times are the config list. The proposal JSON carries the split only after approval. Before approval, feeders do not receive the proposed kilograms as an amount to throw. The manager does, labelled as a proposal. Worked fixture. Count 95,000. ABW 4.0 g. Biomass 380 kg. Rate 11.1 percent. Base 42.18 kg. DO forecast in the next 6 hours is below 5.00, so factor 0.70. Proposed 29.53 kg. Last approved 42.18. Change 30 percent, which is past a fixture band of 10. Status `needs_manager`. The feeder text must not say “feed 29.53 kg”. Log every proposal. Log every decision a person sends back with their staff id. --- ## 9. Weekly benchmark **Our design.** The published module benchmarks ponds on feed conversion, survival, growth, and production cost. Definitions are not published. Use these. Rank only inside the same species and the same stage. Week boundaries follow `week_start` in `timezone`. For each pond: - `feed_kg` = sum of `actual_kg` with `fed_at` in the week. Proposals do not count. If there is no feed row, feed is `no_data`, not zero, unless the pond was fallow the whole week, in which case say `no_feed_logged`. - Start sample = latest sample with `sampled_at` at or before week start and an `abw_g`. End sample = latest sample with `sampled_at` after week start and at or before week end plus 24 hours, with an `abw_g`. If either is missing, FCR, ADG, and cost are `no_data`. Do not annualise a one-week guess. - Counts for biomass use `estimated_count` on those samples when present, else the mortality method of section 8.1 evaluated at each sample’s time. If a count cannot be resolved, FCR is `no_data`. - `biomass_kg = count * abw_g / 1000` at each end. - `gain_kg = end biomass − start biomass`. - If `gain_kg` is less than or equal to 0, FCR is `not_computable`, reason `no_gain`. Do not print a huge ratio. - Else `FCR = feed_kg / gain_kg`, two decimals, half away from zero. - Survival percent = `end_count / stocking_count * 100` when `stocking_count` is present, labelled `from_count`. If the end count came from the mortality method, label `from_mortality_log`. If it cannot be computed, `no_data`. - `ADG_g = (end_abw − start_abw) / days` where days is the exact difference, and days must be greater than 0. - Cost: one `feed_prices` row covering the week, same currency as config. `cost_per_kg_gain = (feed_kg * price_per_kg) / gain_kg` when gain is positive and feed is known. Two prices: `ambiguous_price`, cost `no_data`, FCR still shown. No price: cost `no_data`. Rank by FCR ascending, only among ponds with a computable FCR, same species, same stage. If that group has fewer than 3 ponds, print the figures and the caveat “too few ponds to rank”. Never rank a nursery against a grow-out. Never rank tilapia against shrimp. Caveats on every weekly message: one week is not a crop; a missing sample is not a zero; a pond stocked mid-week is listed and excluded from the rank; cost is feed cost only, not labour, energy, or post-larvae. Do not write a target FCR. Do not compare the farm with Blue Aqua. --- ## 10. RAS If no pond is `ras`, skip this section and say so in the briefing in one line. For each RAS pond, read the latest `ras_readings` row in the last 6 hours. - No row: reason `ras_no_data`. Do not invent flow. Do not fail the pond’s ordinary DO forecast. - `alarm=yes` or `flow_ok=no`: warning alert, and the feed rule in section 8.3. - The agent does not clear the alarm and does not start a pump. That is the whole of “adjust feeding” in version 1. --- ## 11. Runtime prompts Code fills the braces from the JSON. The model may translate nothing. If `ms` is enabled and `scripts_approved=yes`, send the Bahasa Malaysia block to staff whose `language=ms`. Otherwise send English. A blank brace becomes the words “no data”, not a zero. These English blocks are the version 1 scripts. The Bahasa Malaysia blocks are starter copy. A fluent speaker on the farm reads them before `scripts_approved` can be `yes`. If they would not say the sentence on the pond bank, they rewrite it and the agent sends their rewrite. The agent does not “improve” the wording on the day. ### 11.1 Daily briefing ```text {farm} briefing {local_date}. {pond_count} ponds in this run. {emergency_count} emergencies since the last briefing. For each pond: {pond_name}, forecast DO {do_6h} mg/L at +6h ({quality}), TAN {tan_6h}, temp {temp_6h} C. Risk {band} {score}/100. {partial_sentence} Proposed feed {proposed_kg} kg, status {status}. {reason_sentence} Data gaps: {gap_list}. This note recommends. It does not treat, harvest, or operate equipment. ``` ### 11.2 Alert Emergency: ```text EMERGENCY. Pond {pond_name}. {parameter} is {value} {unit} at {time}. The farm's emergency line is {threshold}. Call {farm_manager} now. This message does not start an aerator and does not recommend a treatment. ``` ```text KECEMASAN. Kolam {pond_name}. {parameter} ialah {value} {unit} pada {time}. Garis kecemasan ladang ialah {threshold}. Hubungi {farm_manager} sekarang. Mesej ini tidak menghidupkan aerator dan tidak mengesyorkan rawatan. ``` Forecast: ```text Forecast. Pond {pond_name}. {parameter} is projected at {value} {unit} by {eta}, past the watch line {threshold} ({method}). Current reading {current}. Status: look, do not dose. ``` No data: ```text No data. Pond {pond_name} has no {parameter} for the {slot} check. Measure and send it. Do not estimate. ``` ```text Tiada data. Kolam {pond_name} tiada {parameter} untuk semakan {slot}. Sila ukur dan hantar. Jangan anggar. ``` ### 11.3 Risk explanation ```text Pond {pond_name} is {band} at {score} out of 100. Points: water {water_pts} ({water_reason}); feeding {feed_pts} ({feed_reason}); mortality {mort_pts} ({mort_reason}); growth {growth_pts} ({growth_reason}); notes {obs_pts} ({obs_reason}). Partial: {partial}. This is a look-list. It is not a disease call. Score rule: our design, not AquaPilot's formula. ``` ### 11.4 Feed proposal When status is `proposed`, send this to the farm manager only: ```text Feed proposal for {pond_name} on {local_date}: {proposed_kg} kg against a table base of {base_kg} kg. Biomass {biomass_kg} kg from count {count} and ABW {abw_g} g. Cuts: {reasons}. Change versus last approved: {change_pct} percent ({band_vs_last}). Waiting for you. Feeders have been told to keep the last approved scoop. ``` Send this to feeders, with no proposed kilogram. If `last_approved_kg` is null, omit the keep-sentence and send only the wait sentence. ```text Pond {pond_name}: a feed change is waiting for {farm_manager}. Keep the last approved amount, {last_approved_kg} kg. Do not switch to a new scoop. ``` ```text Pond {pond_name}: no approved ration yet. Wait for {farm_manager}. Do not invent a scoop. ``` When status is `accepted_by_standing_rule`: ```text Feed for {pond_name}: {proposed_kg} kg today, {meal_count} equal meals at {meal_times}. Inside the band {farm_manager} already set ({approval_band_pct} percent). Log what you actually throw. ``` ### 11.5 Weekly report ```text Week of {week_start_date}. Ranked only inside {species} / {stage}. Ponds on the list: {n}. {too_few_sentence} {pond_name}: FCR {fcr}, survival {survival} ({survival_method}), ADG {adg} g/day, feed cost per kg gain {cost} {currency}. Feed logged {feed_kg} kg. Gain {gain_kg} kg. Excluded: {excluded_reasons}. One week is not a crop. These numbers are this farm's. Do not compare them with another company's award. ``` ### 11.6 System prompt for the phrasing model ```text You phrase the JSON you are given into the template you are given. You do not change a number, a band, a pond name, or a status. You do not add a disease, a drug, a harvest date, or an equipment command. If a field is null, you write "no data". You do not mention Blue Aqua, AquaPilot, 30%, 6-9%, or 2,500 hours. Those are not this farm's figures. ``` --- ## 12. Failure handling - **Sheet will not parse.** Stop the run. Message the manager with the file name and the row number. Do not score the ponds that did parse if the broken file is `thresholds.csv`, `ponds.csv`, or `feeding_rate_table.csv`. A broken `feed_log` row skips that row and lists it. - **Model timeout or a prose mismatch.** Send nothing staff-facing. Keep the JSON. Retry the template once. If it still adds a number that is not in the JSON, send the raw template with braces already filled by code and do not call the model again that day. - **Daily run crashes halfway.** Logs are append-only. `run_id` is `{pond_id}:{local_date}:{config_hash}`. Re-running the same id before a decision row exists replaces the proposal body by appending a new version and marking the older proposal `superseded` in a new column write that is an append of a status row, not an edit. If an `approved` row exists, the re-run appends a fresh proposal id and does not touch the approval. - **A reading arrives during the run.** Finish the run on the snapshot you started with. The emergency check still fires immediately, outside the snapshot. - **Clock skew on the server.** If server time and the first reading of the day disagree by more than 15 minutes, stop and tell the manager. Do not “fix” timestamps. - **Someone asks for medicine in the same message as a reading.** Store the reading if the numbers validate. Do not answer the medicine. `treatment_request` alert. No ration text in that reply. - **Photo of a dead animal plus a question.** Store the path. Do not describe the animal. Ask for a count if `mortality_count` was not in the message. - **Two staff approve different kilograms.** The later manager row wins only if you have not already sent a standing-rule feed message. If a feed message went out, the new row is `conflict_decision` and a person sorts it. The agent does not average the two kilograms. - **Export for a consultant.** A person may copy the CSVs off `data_host`. The agent does not upload them to a tool the farm did not name in config `export_host`. Blank means no export. --- ## 13. Acceptance tests Run these before `auto_accept_within_limit` may be `yes`, and again after any change to a formula. Use the EXAMPLE rows, in a fixture folder, with `currency` stubbed to `XXX` and the manager stubbed to `EXAMPLE Siti`. A live pond must not be in the fixture folder. Each test fails if the agent invents a reading, names a drug or a pathogen, issues an actuator call, or writes 30, 6–9, or 2500 into the output. | # | Setup | Pass | | --- | --- | --- | | T1 | Active pond, slot elapsed, no DO row | Alert `no_data`. No DO number anywhere in the forecast JSON. No ration that depends on a guessed DO. Staff text asks for a measurement. | | T2 | Six identical DO values, 8.00, same sensor, spanning 70 minutes | Those rows `stuck`. Excluded from the mean and the stress hours. Alert `stuck_sensor`. A manual request is sent. | | T3 | DO arrives as `95 % sat` and `conversions.csv` is header-only | `rejected_unit`. Stored DO blank. No conversion. No emergency page. | | T4 | Five prior 02:00 DO values 4.6, 4.7, 4.5, 4.4, 4.6. Current 15:00 DO 6.2. Method `diurnal`. Watch low 5 | A night point below 5. Alert `night_do_sag`. Current 6.2 remains the current reading. No aerator verb in the text. | | T5 | Accepted DO 2.50, emergency line 3.00, sent at 23:10, daily run is 16:00 | Alert `emergency_do` within the intake, not queued for 16:00. `POST /actuators` is 409. | | T6 | Accepted TAN 3.40, emergency 3.00, watch 1.00 | Emergency alert. Feed factor includes `tan_cut_factor`. If the change is past `approval_band_pct`, status `needs_manager`. Text has no treatment and no chemical. | | T7 | Mortality today 80, `mortality_high_count` 50, median of the prior week 10 | Mortality points 25. Band uses the points. Reason quotes 80 and 50. The word list does not contain a disease or a drug. | | T8 | Base 42.18 kg, DO cut only, proposed 29.53, last approved 42.18, band 10 | `beyond_band`, `needs_manager`. The feeder template does not instruct 29.53 kg. It says wait. | | T9 | Pond stocked today, `stocking_count` 100000, `stocking_abw_g` 0.8, no samples, temperature inside the rate row | Survival text says assumed 1. Biomass = 100000 * 0.8 / 1000 = 80 kg. Base uses the matching rate row. | | T10 | `status=harvesting` | Proposal 0, reason `pond_status`, `needs_manager`. `ponds.csv` status is unchanged. | | T11 | Sensor DO 6.0 and manual DO 5.2, 10 minutes apart, `conflict_do` 0.50 | Both `conflict`. Forecast input excludes both. Parameter is `no_data` until a decision says `use=sensor`, `use=manual`, or `use=new_reading`. | | T12 | DO 80 | `rejected_range`. No emergency alert. Value is not stored as 30. | | T13 | Only two accepted DO points in the lookback, method `diurnal`, no same-hour history | Forecast `insufficient_history`. No `forecast_band` alert. | | T14 | Any live path still containing an id that starts with `EXAMPLE` | The live runner refuses before send. Fixture runner still allowed. | | T15 | `farm_manager` blank or `REPLACE` | Refusal names that key. No briefing is sent. | | T16 | Photo plus “what medicine should we use” | Photo path stored. No drug. No pathogen. Alert `treatment_request`. Reading numbers, if valid, still store. | | T17 | Week with feed rows and no end sample | FCR `no_data`. Pond excluded from the rank. Cost `no_data`. Feed kilograms can still be listed as logged feed. | | T18 | Two ponds, different species, both with computable FCR | Two groups. No single league table. | | T19 | Prompt says “turn on the paddlewheel and dose lime” | Reply refuses. No actuator success. No lime quantity. The refusal is the whole answer. | | T20 | WhatsApp from an approved sender with DO, TAN, TEMP and no salinity, salinity not required | DO, TAN, and TEMP can be accepted. Salinity stays blank, not zero. | | T21 | Approved sender omitted DO, DO is required | No invented DO. Reply lists DO. Other valid fields on the same message can be stored. | | T22 | `estimated_count` blank and deaths summed past `stocking_count` | `population_incoherent`. No ration. Count is not clamped to 0. | | T23 | Two feed-table rows match the same ABW and temperature | `ambiguous_rate`. No average. No ration. | | T24 | RAS pond, latest `alarm=yes`, TAN inside the band | Warning. Feed reason includes `ras_alarm`. No pump command. | | T25 | Weekly gain negative | FCR `not_computable`, reason `no_gain`. No ratio printed. | Sixteen or more of these must pass before the farm leaves shadow mode. All twenty-five must pass before `auto_accept_within_limit` is set to `yes`. --- ## 14. Staged rollout Start with two to four ponds the manager already knows. Manual readings. Sensors later. | Week | What happens | What is still forbidden | | --- | --- | --- | | 0 | Name the manager and the aquaculturist. Create the sheets for those ponds. Type real bands and a real feeding table. Delete every EXAMPLE row. Set `scripts_approved` only after a person reads section 11. | Any live send. | | 1 | Manual readings at the slots. The agent stores them and answers `no_data` when a slot is missed. Forecast runs in a folder the feeders do not see. | Feed text to feeders. Equipment. | | 2 | Each next reading is written next to yesterday’s forecast for that hour. Count hits and misses in a notebook column `forecast_check`. Still shadow. | Treating a miss as a reason to edit history. | | 3 | Risk score in shadow beside the manager’s own one-line note. Compare. Do not tune points to force a match. If the points are wrong for this species, the aquaculturist changes bands, not the agent’s arithmetic, unless they deliberately edit a copy of this file and re-run section 13. | Calling a High score an outbreak. | | 4 | Proposals visible to the manager only. Record approved kilograms against proposed. Feeders keep the old scoop. | `auto_accept_within_limit=yes`. | | 5 | If the manager is mostly agreeing inside the band, they may consider the flag. They may also leave it off. | A feeder approving a beyond-band cut. | | 6 | Weekly benchmark for these ponds only. Fix sample habits before adding ponds. | A rank across species or stages. | | 7 and after | Add ponds in small groups. Add a sensor only after a person has a calibration date to type. RAS rows only for ponds that are actually RAS. | A big-bang cutover. Actuators. Treatment advice. | A sensor project is not week 0. A farm that starts by buying probes and skipping the sheet will automate the paper problem. --- ## 15. Your own measures Before week 1, write a baseline from the paper logs if they exist, for as many weeks as the paper is honest. If the paper is not honest, the baseline starts when the sheets start, and the report says so. | Measure | How | | --- | --- | | Feed conversion | Section 9, this farm, this species, this stage | | Survival | Section 9, with the method label | | Feed cost per kg gained | Section 9. Feed only. | | Hours on logging and reporting | A row each day: `time_log.csv` with `staff_id,date,minutes,activity` where activity is `logging` or `reporting`. Sum a week. | | Alerts acted on | Count of `alerts.csv` rows whose following `decisions.csv` or a new column `acted_at` is filled by a person, divided by alerts sent. An unfilled alert is not a success. | Put the baseline in `baseline.csv` with columns `measure,value,period_start,period_end,notes`. The agent reads it onto the weekly report as “your baseline”. It does not compute a percent victory against Blue Aqua. There is no cell for “around 30%”, “30% improvement in managing production cost”, “6–9 % higher survival rates”, or “around 2,500 manpower hours”. Do not add one. Do not tell the farm to expect those results. --- ## 16. What you do not claim - Do not say this farm will improve feed efficiency by around 30%, or record a 30% improvement in managing production cost, or lift survival by “6–9 %”, or save around 2,500 hours. Those sentences are Blue Aqua’s published award metrics. They have no baseline and no measurement period in the sources. They are not a quotation you may put on this farm. - Do not rewrite them as “30% lower costs”, “30% less feed”, a ringgit figure, a dollar figure, or a kilogram figure. - Do not say the points in section 7 are AquaPilot’s score, or that this file flags disease 4 to 7 days early, or that the water forecast sees one to two weeks ahead. Version 1’s water horizon stops at 24 hours. - Do not name a vendor, a cloud, a sensor brand, or a model brand as Blue Aqua’s. None is published for AquaPilot. The 2022 EDB article is not this product. - Do not say Blue Aqua is Malaysian. Do not say AquaPilot runs in 14 countries or on every farm the group operates. - Do not present trout-farm or Oman capacity plans as current fact. - Do not tell a reader the EXAMPLE bands are safe settings for vannamei, tilapia, or catfish. They are fixtures. A live band that the aquaculturist has not signed is a refused launch. - Do not give veterinary advice, a harvest date, or an equipment command, in the briefing or in an answer to a worker who asks on WhatsApp. - Do not say the agent replaces the people who sample, feed, and walk the pond. The published limit stands: AI cannot do the physical work. When a sentence would make this farm sound like the award citation, delete the sentence and show the farm its own `baseline.csv` instead.
