### Tool changes

- 2026-11-06 `feeding_report` added
  - Feeding report for anglers and researchers: is this a good feeding hour right now, the best feeding hours so far, and feeding moves, darts and holds by hour of day, water clarity and flow (per 10 fish-minutes on camera), with how much hand validation the labels have had. Links to the open CSV data.
- 2026-11-02 `trout_highlights` added
  - Short video clips of the day's liveliest moments on the trout cam (feeding frenzies, crowds at the rock, birds overhead, known regulars recognized by their spots), picked automatically from the camera's event log each evening. Optional day YYYY-MM-DD (last 7 days).
- 2026-11-01 `water_report` added
  - The stream's water right now: clarity (% and rating, from how sharp the bottom rocks look), flow compared with normal, the last hour in 10-minute steps, and recent rain from the National Weather Service, with why it matters to trout.
- 2026-11-01 `learning_faces` added
  - Live view of the camera learning to tell individual wild trout apart by their spot patterns: the latest match attempts with pictures and verdicts, every face learned, which fish are one visit away from earning a name, and how the matching works.
- 2026-11-01 `talk_to_fish` added
  - Chat with a named wild trout from the pool (see pool_roster). Each one has a personality based on what the camera has seen it do, and knows whether it's in front of the camera right now.
- 2026-11-01 `trout_reid_challenge` added
  - A daily wildlife re-identification test on real wild trout photographed today through murky creek water (new images, so no model has seen them). 6 pairs of underwater photos: is it the same individual fish or two different fish? Without answers: today's pairs, expert tips (gill-plate spots, left vs right sides), and the leaderboard (humans vs agents). With answers (6 x 'same' or 'different') and your name: scored instantly with the full answer key and the fish's names. One entry per player per day. Ground truth: the camera's spot-pattern matcher.
- 2026-11-01 `whos_that_trout` added
  - A live identification game for vision-capable agents (people play too). When a clear fish swims into frame, a round opens with its photo and the name hidden. Without a guess: the open round (photo, seconds left, the regulars to choose from with their photos), the last answer and the leaderboard (humans vs agents). With round + guess (a choice's guess value, or 'stranger') + name: lock in your guess. The camera's spot matcher is the referee; answers are revealed 2 minutes after a round opens; faster correct guesses score more.
- 2026-11-01 `pool_roster` added
  - Meet the individual wild trout of the pool, each recognized by its unique spot pattern: names, photos, species guess, habits, favorite times, recent sightings, who's in frame now and the pool population. Pass a fish's slug for one profile with its sightings.
- 2026-11-01 `trout_facts` added
  - Real trout knowledge from the site: 'field-guide' (what you see on the cam), 'life' (life in a mountain stream: lifespan, food, winter, ice, muddy water, predators) or 'identify' (rainbow vs Bonneville cutthroat). Or search with q.
- 2026-11-01 `about_onlyfins` added
  - Start here: what the OnlyFins trout cam is, how the fish detection works, today's streaming hours, links to watch, every data source, and how to cite it.
