What is nfl-analytics CLAUDE.md?

A project instruction file for an NFL analytics repository, including its warehouse, commands, query practices, testing, and data workflows. An analytics warehouse is a structured store of data used to answer questions with queries.

Use it when working in the repository to query its DuckDB database, rebuild data and views, run tests, handle front-end or automation tasks, and follow its release process.

It gives the coding agent the project’s local rules, reducing mistakes such as writing to the database during analysis or querying the wrong tables. It also points to the commands and documentation needed for routine work.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02205	$0.02205
Opus 5.5	$0.00882	$0.00882

Security

Grade A, and why

nfl-analytics CLAUDE.md 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.

NFL Analytics Warehouse

Repo: https://github.com/parthakker/nfl-analytics (public, MIT). Local git identity is Parth's personal email (repo-local config). data/* (except the three hand-curated JSONs), *.duckdb, and logs/ are gitignored — fresh clones rebuild via nfl refresh --bootstrap. Commit when Parth asks; follow /release for the ritual.

Personal NFL analyst project. Questions are answered by running SQL against nfl.duckdb (DuckDB, repo root) — computed answers, not retrieval. Before non-trivial SQL, load the warehouse-queries skill (table grid, view catalog, query patterns); per-table dictionaries live in docs/dictionary/*.md.

How to query

python -c "import duckdb; con=duckdb.connect('nfl.duckdb', read_only=True); print(con.execute('''<SQL>''').fetchdf().to_string())"

Always read_only=True for analysis. Never write to any *.duckdb outside the build scripts (enforced by permissions.deny).

Commands

nfl <cmd> (or python -m nfl_analytics.cli <cmd>): refresh / rebuild / views / audit / smoke / weather / train / news / kalshi / fixture. Rebuild = nfl rebuild then nfl views (~60s).
Tests: pytest tests/unit (fast, no DB) · pytest -m warehouse (real-DB invariants) · pytest -m api (TestClient contracts) · cd web/ui && npm run e2e (Playwright vs live server). Prefer running single tests, not the whole suite. CI runs unit + fixture tiers (NFL_TEST_USE_FIXTURE=1).
Chat answer quality has its own suite: python scripts/run_chat_evals.py (evals/, 28 questions × 4 moments). Costs real API budget and is manual — re-run the affected --moment slice after editing CLAUDE.md, mcp_server.py or chat.py, and --compare against the previous run dir.
UI rebuild after web/ui edits: cd web/ui && npm run build.
Jarvis (primary UI): "NFL Jarvis" shortcut or python web/run_web.py (:8000). Legacy Streamlit lives in legacy/ — frozen, don't extend.

Front end

web/ — FastAPI routers (web/api/) + React/Vite/Tailwind SPA (web/ui/). Nav is 6 sections + More: Today / · Scores /scores · Teams /teams · Players /players · Betting /betting · Learn /knowledge; under More sit Leaders, Coaches, Refs, H2H, Markets, News. Details are singular (/team/:code, /player/:gsis, /coach/:name, /matchup/:gameId). Old paths redirect, unknown paths go to /. Ctrl-K is a moded command palette (jump / > commands / ? analyst) in components/CommandPalette.tsx.

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.
