Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_leagueA | Resolve a Sleeper username to a user_id and list that user's NFL leagues for a season (defaults to the current NFL season). Use the returned league_id with the other tools. |
| get_draft_infoA | Draft settings for a league (or an explicit draft_id): draft type (snake/linear/auction), status, team count, rounds, third-round-reversal flag, the slot -> roster -> owner mapping, and the league's required starting slots. |
| get_draft_picksA | Ordered list of picks already made in a draft. Poll this every 5-10s during a live draft. Player names/positions/teams are resolved from the cached player dictionary (falling back to pick metadata). |
| get_available_playersA | Players not yet drafted in this draft, from the cached dictionary minus the picks made. Sorted by Sleeper's search_rank (rough ADP; lower is better). Defaults to fantasy positions only and drops unranked players. |
| whose_turnA | Compute the pick currently on the clock from the number of picks made, using snake-draft math (honours linear drafts and third-round reversal). Pass my_roster_id to get an on_the_clock flag and picks-until-your-next-turn. |
| get_my_roster_needsA | Compare the players a roster has drafted so far against the league's required starting lineup and flag thin positions. Needs the league's roster_positions, so pass league_id (or a draft_id whose league is known). |
| get_trending_playersB | Sleeper's trending players (most added or dropped across all leagues in the lookback window). Rough signal only — NOT rankings or ADP. |
| refresh_player_cacheA | Re-download Sleeper's /players/nfl dictionary (~5MB) and rewrite the disk cache. Normally automatic (daily); use this if names look stale. |

Scored across 8 tools
Each tool targets a clearly distinct task: market trends, cache refresh, on-the-clock computation, roster needs, league resolution, draft settings, draft picks list, and available players. While whose_turn and get_draft_picks both relate to draft state, their descriptions separate the calculation from the raw list, eliminating ambiguity.
Six of eight tools follow the get_<noun> snake_case pattern, but refresh_player_cache uses a different verb and whose_turn is a sentence fragment rather than a verb_noun action. The inconsistency is minor and naming remains predictable overall.
Eight tools form a focused and well-scoped set for live-draft assistance, covering data acquisition, draft configuration, pick tracking, turn calculation, and roster analysis without bloat. The cache refresh tool, though maintenance-oriented, is justified by the large player dictionary requirement.
The tool surface covers the full workflow for preparing and executing a draft: resolve a user's league, fetch draft settings, poll picks, determine whose turn it is, evaluate roster needs, and list undrafted players. No essential draft-related operation is missing, and the trending players tool adds useful pre-draft signal.
