nfl-analytics: Skill for Claude Code

.claude/skills/rebuild/SKILL.md

rebuild is a skill for Claude Code from parthakker/nfl-analytics. It costs 18 tokens per session (198 once invoked), scanned A, original, MIT.

A rebuild procedure that recreates an NFL analytics warehouse—a database for storing prepared football data—and its derived views from data already on disk.

In plain words
What is it for?
Use it after changing downloaded data or warehouse-building code, then run the warehouse tests and check the travel-data result.
Why use it?
It provides a repeatable way to regenerate the database and check that the rebuilt data is usable. It also points out common failures such as missing files or a database lock.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rebuild scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Rebuild warehouse

  1. Preflight: explore.cmd (DuckDB browser UI) must be closed — the rebuild deletes and recreates nfl.duckdb.
  2. python -m nfl_analytics.cli rebuild (raw tables, ~60s) then python -m nfl_analytics.cli views (venues, weather parse, views, macros).
  3. Both must exit 0; views output ends with "travel sanity OK". Then python -m pytest -m warehouse -q.
  4. If a table fails with "no files match": non-optional glob missing from data/ — run /refresh-data instead. If the Jarvis server was up during the rebuild it may hold a stale handle — restart it if /api/health degrades.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
