Tools as reported by the server

• get_current_insights
  Muffed's published editorial reads on what is real in the NFL right now — each one a dated, sourced claim with its supporting figures, from the /trends board.
• query_stat_leaders
  Top entities on one verified metric for one season, pre-sorted, each with the source's own rank and the population it was ranked against. Takes a verified panel metric key.
• get_entity_metrics
  The verified figures Muffed holds for one NFL player or one NFL team (by name or abbreviation, e.g. "Bijan Robinson" or "DEN"), with the source's rank where one exists. By default the headline figures for that player or team; scope "all" returns every figure held, and a named metric returns all of t
• compare_entities
  Two players or two teams shown side by side — by default on the metrics that matter for their position, on named metrics when `metrics` is set, and on the full set with all:true. Each side carries its source rank. States both figures and stops: it names no winner, no margin and no recommendation. `m
• get_metric_definition
  Muffed's published definition of a verified metric — what it measures, in plain language, from the glossary page for that term — plus which seasons it actually covers, how it is ranked, its licence and its attribution. Accepts a metric key or a common name ("cpoe", "rushing yards over expected"). Se
• list_metrics
  What Muffed can answer on. By default a summary of metric families with their counts and season coverage; with search or detail:true, individual metric keys. Returns keys and coverage only, never figures.
• search_metrics
  The verified metrics that match a topic — e.g. 'screens', 'blitz', 'time to throw' — ranked by a text match over each metric's key, label, common names and board description. Up to 20 entries, each with its key, subject, season coverage and the board it belongs to. Keys and coverage only, never figu
• verify_claim
  Checks structured claims against Muffed's verified panel. Each claim comes back confirmed, wrong (with the actual value), or unverifiable (with the metric's real season coverage). Takes structured fields only, not sentences.
• get_backfield
  Muffed's published handcuff page for one team's backfield, plus the current depth chart and injury status from Sleeper. Answers who backs up a starter, and who replaces one who is out.
• run_stat_query
  Computes an NFL figure from a structured query rather than looking one up: a population (position, qualifying threshold), a window (seasons, weeks, a team span, a coach's tenure), one named measure, and one operation (leaders, rank, count, only-who, a per-season streak, or a share of a total). Answe
• sleeper_find_leagues
  Lists the NFL leagues a Sleeper username belongs to, with each league's id. Muffed stores nothing about the requester.
• sleeper_get_league
  One league's name, season, size, current week, detected scoring format, and the manager-to-roster map.
• sleeper_matchup_preview
  Both sides of a league matchup, with the verified figures Muffed holds for the players involved and each team's record. Muffed does not project outcomes, name a winner, or recommend a lineup.
• sleeper_roster_stories
  One team's roster mapped to the verified figures and published Muffed surfaces for each player. Players Muffed does not cover are listed as uncovered rather than omitted.
• sleeper_standings_story
  League standings derived from Sleeper's roster settings — records, points for, and points against where available. Sleeper publishes no standings endpoint, so these are computed from the roster rows.
