nfl-analytics: Skill for Claude Code

.claude/skills/new-view/SKILL.md

new-view is a skill for Claude Code from parthakker/nfl-analytics. It costs 30 tokens per session (298 once invoked), scanned A, original, MIT.

A checklist for adding or substantially changing a derived SQL view in a warehouse, including its definition, tests, documentation, and catalog entry.

In plain words
What is it for?
Use it when creating a warehouse view: load the query guidance, add the SQL, run it, write an invariant test, update the data dictionary and catalog, and adjust test fixtures if needed.
Why use it?
It reduces the chance that a new view has incorrect joins, incomplete source data, or silent data errors. It also keeps the view understandable and included in the project’s test setup.

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

new-view 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

New warehouse view checklist

  1. Load the warehouse-queries skill first (grains, join keys, traps).
  2. SQL into the VIEWS dict in scripts/build_views.py — WITH a leading comment stating the grain and any convention (team-perspective spread, ref_key aggregation, canon_team usage). Tables the view needs must be created before the VIEWS loop.
  3. python -m nfl_analytics.cli views — confirm the row count printed for the new view is plausible.
  4. Invariant test in tests/warehouse/ (row floor, symmetry/identity, or a pinned known value — whatever would catch silent corruption). Must pass on the CI fixture too (derive seasons from the DB; pytest.skip if the fixture slice can't contain the data).
  5. Dictionary: add/extend the relevant docs/dictionary/*.md.
  6. Catalog: one line in .claude/skills/warehouse-queries/SKILL.md views list.
  7. If the fixture needs the view's source tables: check scripts/make_fixture.py SLICED/FULL_COPY lists, rebuild via nfl fixture if so.

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.
