README

Fantasy Dynasty Agent — Sleeper

**Dynasty / keeper league prep & research agent for the Sleeper app, built for auction drafts.**

Fantasy Dynasty Agent pulls your league straight from Sleeper, scores every player with *your league's own scoring settings* (custom PPR, IDP, anything), decodes every team's keepers and keeper costs, and prices the whole player pool in auction dollars for your exact team count, roster and budget. An optional Claude-powered research agent checks injuries, arrests/suspensions, depth charts and role news with cited sources.

Piece	What it does
`dynasty_agent/sleeper.py`	Client for Sleeper's public, keyless API (league, rosters, users, drafts, picks, players, stats, projections)
`dynasty_agent/scoring.py`	Scores raw stat lines with the league's `scoring_settings` — reproduces custom/IDP scoring exactly
`dynasty_agent/keepers.py`	Last-year auction prices, keeper cost (`last price + $5` by default), league-wide keeper decoding, keeper surplus ranking
`dynasty_agent/valuation.py`	League-wide starter fill → replacement level → VORP → auction dollars (net of keeper spend and one-dollar minimums) → points per dollar
`dynasty_agent/agent.py`	Claude research agent with web search (needs your own Anthropic key)
`dynasty_agent/api/app.py`	HTTP API with public and private routes
`web/draft_board.html`	Live auction board: sortable (rank, player, pos, est. value, pts, PPG, VORP, points per dollar), sticky header, mark drafted with price → My team / Other team, auto-filling roster board, budget left & max bid
