Data transformation and parsing
football-data
by machina-sports
Football (soccer) data across 13 leagues — standings, schedules, match stats, xG, transfers, player profiles. Zero config, no API keys. Covers Premier League, La Liga, Bundesliga, Serie A, Ligue 1, MLS, Champions League, World Cup, Championship, Eredivisie, Primeira Liga, Serie A Brazil, European Championship. Use when: user asks about football/soccer standings, fixtures, match stats, xG, lineups, player values, transfers, injury news, league tables, daily fixtures, or player profiles. Don't use when: user asks about American football (NFL), basketball (NBA), baseball, or any non-soccer sport. Don't use for live/real-time scores — data updates post-match. Don't use get_season_leaders or get_missing_players for non-Premier League leagues (they return empty). Don't use get_event_xg for leagues outside the top 5 (EPL, La Liga, Bundesliga, Serie A, Ligue 1).
tennis-data
by machina-sports
ATP and WTA tennis data via ESPN public endpoints — tournament scores, season calendars, player rankings, player profiles, and news. Zero config, no API keys. Use when: user asks about tennis scores, match results, tournament draws, ATP/WTA rankings, tennis player info, or tennis news. Don't use when: user asks about other sports. Don't use for live point-by-point data — scores update after each set/match.
fastf1
by machina-sports
Formula 1 data — race schedules, results, lap timing, driver and team info. Powered by the FastF1 library. Covers F1 sessions, qualifying, practice, race results, sector times, tire strategy. Use when: user asks about F1 race results, qualifying, lap times, driver stats, team info, the F1 calendar, or Formula 1 data. Don't use when: user asks about other motorsports (MotoGP, NASCAR, IndyCar, WEC, Formula E). Don't use for F1 betting odds or predictions — use kalshi or polymarket instead. Don't use for F1 news articles — use sports-news instead.
SKILL.md
by owasp-dep-scan
For WASM parsing changes, verify both normalized fields (imports, dynamic_entries, functions) and raw passthrough fields (wasm_report, wasm_analysis).
monitor-fly-io-usage
by iterate
Monitor Fly machine health and use focused playbooks.
grace-reviewer
by osovv
"GRACE integrity reviewer. Use when validating semantic markup correctness, contract completeness, knowledge graph consistency, or after code changes to ensure GRACE conventions are maintained."
grace-execute
by osovv
"Execute the full GRACE development plan step by step, generating code for each pending module with validation and commits. Use when the architecture is planned and you want to generate all modules sequentially with review checkpoints."
logophile
by tkersey
"Precision copy edits + naming: compress and clarify without changing meaning. Triggers: $logophile, rewrite/reword/rephrase, shorten, rename titles/labels/headings. Avoid operational scope/validation tasks unless rewriting is explicit."
learnings
by tkersey
"Capture and persist evidence-backed execution learnings into .learnings.jsonl. Trigger cues/keywords: $learnings, lessons learned, takeaways, wrap up, handoff, before commit/PR, after tests pass, fail-to-pass, strategy pivot, footgun, retry loop."
data-driven-testing
by NeverSight
"DEPRECATED: Use testing-best-practices instead. This skill has been retired."
capital-rotation
by Innei
Use when reading today's US-market capital flow across multiple sectors to identify rotation direction — e.g. "今天资金流向", "板块强弱", "rotation map", "卖芯买云", "where is money moving today", "scan flows across sectors". Produces a cross-section snapshot of net inflows by cohort (indices / semis / software-cloud / mega-tech / AI applications), names the dominant narrative, and writes a dated journal file. Different from market-session-tracker (intraday live monitoring of a single watchlist) — this is a one-shot end-of-session rotation read.
fred
by Innei
US/global macro time series from St. Louis Fed FRED — CPI, GDP, Fed funds, yields, M2, DXY, etc.
market-session-tracker
by Innei
Use when monitoring stocks/ETFs/indices across pre-market, open, intraday, or close — especially when the user is reading session action live and may revise their take as it unfolds. Triggers include 盘前/盘中/收盘 sessions, multi-symbol watchlists (e.g. MU/TSM/SMH semi tracking), user observations like "突破"/"冲高"/"回调"/"假突破", capital flow checks, market temperature checks, semi/AI/memory plays, and any request that bundles a position context with a live read.
gdelt
by Innei
Global multilingual news event stream with tone scoring via GDELT 2.0 Doc API.
profiling-tables
by astronomer
Deep-dive data profiling for a specific table. Use when the user asks to profile a table, wants statistics about a dataset, asks about data quality, or needs to understand a table's structure and content. Requires a table name.
project-planning
by athola
"Transform specifications into implementation plans with architecture design and dependency-ordered tasks. Use for spec-to-plan conversion, task breakdown, effort estimation. Skip if no spec exists."
project-specification
by athola
"Transform project briefs into testable specifications with acceptance criteria. Use for requirements translation, spec creation, pre-implementation. Skip if spec exists or still exploring."
