nfl-analytics: Skill for Claude Code

.claude/skills/refresh-data/SKILL.md

refresh-data is a skill for Claude Code from parthakker/nfl-analytics. It costs 14 tokens per session (259 once invoked), scanned A, original, MIT.

A data-refresh procedure that downloads updated NFL data from nflverse, a public source of NFL statistics, then rebuilds and checks the analytics warehouse.

In plain words
What is it for?
Use it for weekly updates, a complete historical refresh, or a fresh data download, followed by weather processing, view rebuilding, and warehouse tests.
Why use it?
It makes updating the local database repeatable and identifies download problems, missing files, row-count issues, and failed validation checks.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter.

This is parthakker/nfl-analytics's own configuration. It tells Claude Code how to work on nfl-analytics itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nfl-analytics configures →

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

refresh-data 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 2mo 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

Refresh data

  1. Preflight: make sure nothing holds a write lock — explore.cmd (DuckDB UI) must be closed; check logs/refresh.log tail for an already-running refresh.
  2. Run python -m nfl_analytics.cli refresh $ARGUMENTS
    • no flag: weekly mode (current + last season assets + schedules)
    • --full: every season in the manifest
    • --bootstrap: fresh-clone download (~2 GB, resumable) This downloads, runs fetch_weather, rebuilds warehouse + views, snapshots Vegas lines.
  3. Verify: the build output must end with "All tables loaded" and "travel sanity OK"; then run python -m pytest -m warehouse -q.
  4. Report: assets fetched, any FAILURES lines, row-count anomalies, and the refresh.log line. If a download failed with "no candidate matched", nflverse likely renamed an asset — check their releases page before editing the manifest in scripts/refresh_data.py.
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.
