Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-11-05 (score 83, +1) No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes. ### 2026-11-03 (score 82, +16) - [security improvement] Malware scan: unverified → pass ### 2026-11-02 (score 66, −13) - [security regression] Malware scan: pass → unverified - [functional improvement] Stability: unverified → 0.13 - [functional] Package version: 0.2.0 → 0.2.1 ### 2026-10-30 (score 79, 0) - [functional regression] Security disclosure: unverified → fail ### 2026-10-29 (score 79) First indexed and scored. ## MCP tools (5) ### `baseball_player_history` (~211 tokens) Year-by-year MLB batting and/or pitching statistics for one player's whole career, from the SABR Lahman Baseball Database (1871-2025). Pass a player NAME ("Babe Ruth", "Walter Johnson") or an exact Lahman player_id (e.g. "ruthba01") -- a name is resolved by exact then fuzzy match; if more than one player matches, a list of candidates (with player_id, birth year, debut) is returned instead of a guess, so the caller can re-ask with the exact player_id. Returns every season the player appears in Batting.csv and/or Pitching.csv (most players have only one; a few, like Babe Ruth, have both). Each season row has team, league, games and the standard counting stats. Unknown or ambiguous names are refused with a clear error/candidate-list, never an empty success. Input parameters: - `player` (string, required): Player name ("Hank Aaron") or exact Lahman player_id ("aaronha01"). ### `baseball_team_season` (~202 tokens) One MLB team's full-season record and stats for one year, from the SABR Lahman Baseball Database (1871-2025): wins/losses, division/league/World Series result, runs scored and allowed, team batting and pitching totals, home park and attendance. Pass team as a 3-letter-ish code ("NYA", "BOS") or a common name ("Yankees", "Red Sox", "Dodgers") -- codes changed for some relocated/renamed franchises over the years (e.g. the Athletics' code changed for 2025), so an unrecognized code for that year is refused with a clear error rather than an empty success; try the franchise's name instead, or call with a nearby year to see what code that franchise used. Input parameters: - `team` (string, required): Team code ("LAN") or common name ("Dodgers"). - `year` (number, required): Season year, e.g. 1927. ### `baseball_game_log` (~256 tokens) Box-score-level summary of MLB game(s) played by one team on one date, from Retrosheet game logs (1871-2025): final score, game length, day/night, park, attendance, winning/losing/saving pitcher, managers, and each side's at-bats/hits/doubles/triples/homers/RBI/walks/strikeouts/errors. Covers regular season plus All-Star, Division Series, League Championship Series, Wild Card and World Series games (see game_type in the response: R/A/D/L/C/W). Pass date as "YYYY-MM-DD" or "YYYYMMDD" and team as a code ("NYA") or common name ("Yankees"). Returns an array because doubleheaders are two games on one date. This is a per-game SUMMARY, not a play-by-play log -- no pitch or at-bat level detail is stored. No games found for a valid date/team combination is reported as found:false with the reason, never an empty array treated as success. Input parameters: - `date` (string, required): Game date, "YYYY-MM-DD" or "YYYYMMDD". - `team` (string, required): Team code ("BOS") or common name ("Red Sox"). ### `baseball_season_leaders` (~349 tokens) Top players in one MLB season for one statistic, from the SABR Lahman Baseball Database. Batting stats: HR, AVG, RBI, R, H, SB, BB, SO, 2B, 3B (AVG = hits/at-bats, qualified at a simple AB>=100 floor -- NOT MLB's official plate-appearance qualifying rule, so this can include players who would not qualify for an official batting title). Pitching stats: W, ERA, SO_P, SV, L, WHIP (SO_P = pitcher strikeouts, to avoid colliding with batting SO; ERA and WHIP are qualified at a simple IPouts>=100 i.e. ~33 innings floor, also not the official rule). Pass stat exactly as listed (case-sensitive). Optionally scope to one league ("AL" or "NL"; pre-1901 leagues like "NA", "AA", "UA", "PL" also appear in the data). limit caps how many rows come back (default 10, max 50). An unrecognized stat name is refused with the list of valid ones, never an empty success. Input parameters: - `league` (string): Optional: scope to one league code ("AL", "NL", or an historical league code). - `limit` (number): Max rows to return, 1-50. Default 10. - `stat` (string, required): One of: HR, AVG, RBI, R, H, SB, BB, SO, 2B, 3B, W, ERA, SO_P, SV, L, WHIP. - `year` (number, required): Season year, e.g. 1998. ### `baseball_coverage` (~75 tokens) What this pack actually has loaded right now: the Retrosheet game-log date range, how many games, the latest Lahman season year, and when it was last loaded. Call this if a query for a date or year you expect to exist comes back not-found, to rule out a coverage gap before assuming a typo. ## Diagnostics Captured diagnostic sections: Provenance, Dependencies.
