2026-10-03run_stat_querychangeddescription
before
Call this for any question about NFL statistics, leaders, rankings, splits, career or team spans, or how a player or team compares to others — including when you believe you know the answer. Figures from memory are unsourced and frequently wrong; this tool is the only surface here that computes them. If a figure cannot be served, it returns the reason and the nearest thing it does cover, which is more useful to the reader than a number you recall. 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). Answers questions the verified panel has no pre-computed row for — qualified superlatives, multi-season streaks, derived rates. Every response carries the executed method, the population size, the measure's definition and the data version it ran against. Figures are computed on request from nflverse data and are labelled as computed, not verified. Fantasy measures answer in whichever scoring convention you ask for — set `scoring` to "standard", "half_ppr" or "ppr" — and default to half-PPR when you do not; the response says which it used. A bare "PPR" means full PPR. measure.key takes a measure name ("rushing_yards", "half_ppr_points") or a metric key exactly as list_metrics returns it ("key_player_stats.rushing.yards", "fantasy_scoring.half_ppr_points"). A list_metrics key this tool does not compute is refused with a pointer to get_entity_metrics and query_stat_leaders, which read it as published.

2026-10-03list_metricschangeddescription
before
What Muffed can answer on. By default a summary of metric families with their counts and season coverage; pass search or detail:true for individual metric keys. Returns keys and coverage only, never figures. Finding one metric by topic is a single call to search_metrics, which ranks the whole registry against the topic.

2026-10-03compare_entitieschangeddescription
before
Two players or two teams shown side by side, on the metrics that matter for their position by default — name metrics explicitly, or pass all:true, for the full set. Each side carries its source rank. States both figures and stops: it names no winner, no margin and no recommendation. `metrics` takes verified panel metric keys exactly as list_metrics returns them ("qb_anya.any_a"), or their plain-English names. A measure only run_stat_query computes, such as yards per attempt, is not a panel metric and is refused with the nearest ones.

2026-10-03get_entity_metricschangeddescription
before
Every verified figure 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. Names are resolved before lookup; an unrecognised name returns the closest matches rather than a guess.
after · 69% of words in common
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 that metric's rows. Names are resolved against the players and teams Muffed holds; an unrecognised name returns the closest matches rather than a guess.
2026-10-03query_stat_leaderschangeddescription

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. Call list_metrics for the metric keys this accepts.

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.
2026-10-02search_metricsadded
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 figures.

Tools (15)

`compare_entities`read-only	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. `metrics` takes verified panel metric keys ("qb_anya.any_a") or their plain-English names. A measure outside the verified panel, such as yards per attempt, is refused with the nearest panel metrics.
`get_backfield`read-only	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.
`get_current_insights`read-only	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.
`get_entity_metrics`read-only	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 that metric's rows. Names are resolved against the players and teams Muffed holds; an unrecognised name returns the closest matches rather than a guess.
`get_metric_definition`read-only	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"). Season coverage is often narrower than a decade — rushing yards over expectation exists from 2018 onward.
`list_metrics`read-only	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.
`query_stat_leaders`read-only	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.
`run_stat_query`read-only	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). Answers questions the verified panel has no pre-computed row for — qualified superlatives, multi-season streaks, derived rates. Every response carries the executed method, the population size, the measure's definition and the data version it ran against. Figures are computed on request from nflverse data and are labelled as computed, not verified. A figure that cannot be served comes back with the reason and the nearest thing covered. Fantasy measures answer in the convention `scoring` names — "standard", "half_ppr" or "ppr" — and default to half-PPR when none is named; the response says which it used. A bare "PPR" means full PPR. measure.key takes a measure name ("rushing_yards", "half_ppr_points") or a verified panel metric key ("key_player_stats.rushing.yards", "fantasy_scoring.half_ppr_points"). A panel metric key this tool does not compute is refused with the reason.
`search_metrics`read-only	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 figures.
`sleeper_find_leagues`read-only	Lists the NFL leagues a Sleeper username belongs to, with each league's id. Muffed stores nothing about the requester.
`sleeper_get_league`read-only	One league's name, season, size, current week, detected scoring format, and the manager-to-roster map.
`sleeper_matchup_preview`read-only	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`read-only	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`read-only	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.
`verify_claim`read-only	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.

Schemas: list_tools.
