One agent that knows your whole roster, your matchup, and every other team in your league — start/sit, drops, waivers, who's got surplus at your weak spot. Ask it anything and get an answer backed by real usage and matchup numbers, not a projection with a bow on it.
No password, no draft import — just your Sleeper username.
Every call, every week
Start/sit, drops, waiver priorities — for your actual roster, every card showing the specific signal behind it: target share, red-zone share, efficiency trend, how the defense you're facing gives up yards, the game's implied total.
Ask anything
Chat with an agent that can see your roster, your record, your matchup, and every team's composition in the league. When the data isn't there it says so instead of making something up — and when it's last season's, it's labeled stale.
Trade composition
See which teams have real surplus at your weak spot before you open trade talks — composition, not a made-up valuation dressed up as advice.

Matchup-fit accuracy (unlocks once Phase 4's coverage classification lands)
Retrieval measured 2026-09-20 against the leagues' own data (evals/results). Decision accuracy has been backtested too — the number and its caveats are in the README, and the eval is being redesigned before it goes on this page. Matchup-fit is a placeholder until its eval exists, never invented.
Built for one league. Works for yours too.
Started as a tool for one 12-team half-PPR league. Now it reads your league's own scoring, rosters, and matchups the same way.

Only leagues Sleeper lists for your username can be opened today (the API checks) — pasting an ID you're not in returns a clear error, not a guess.
Which teams have surplus at your weakest spot is answered by the chat agent's league-roster tool, not a report — open Moves → Trades to ask. Valuation/fairness grading isn't built (Phase 6); this is composition only.
AM
Ask about your roster, a matchup, or who to start. Every answer cites the tools it actually used, and says so when it can't ground something.

COMPOSITION · NOT A VALUATION
Asks the chat agent which position you're thinnest at and which teams roster surplus there — real league roster data via its get_league_rosters tool. It counts as one of today's chat queries, so it runs on request. Fairness/valuation grading is Phase 6, not built.
