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 | $0.01026 | $0.01026 |
| Opus 5.5 | $0.00410 | $0.00410 |
| Sonnet 5.5 | $0.00205 | $0.00205 |
| Haiku 4.5 | $0.00103 | $0.00103 |
Grade A, and why
Opensource-Contribution-Leaderboard AGENTS.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.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quick Orientation

|---|---|
| Frontend entry | src/index.js |
| Frontend HTML | index.html |
| Backend server | src/server/app.js |
| GitHub data fetcher | src/server/refresh.js |
| GitHub API wrapper | src/server/util/API.js |
| Utility helpers | src/server/util/Util.js |
| Config template | src/server/config-example.json |
| Live config (gitignored) | src/server/config.json |
| Admin panel | admin/ (separate webpack build) |
| Webpack config (main) | build/webpack.config.js |
| Webpack config (admin) | admin/build/webpack.config.js |
| REST API docs | REST-API.md |
| Cached leaderboard data | src/assets/data/data.json (auto-generated) |
npm Scripts
| Command | What it does |
|---|---|
npm run add |
Installs dependencies for root, server, and admin |
npm start |
Dev mode — webpack-dev-server with hot reload on :8080 |
npm run serve |
Starts the backend server (run in separate terminal during dev) |
npm run build |
Production build — compiles admin + main frontend |
npm run lint |
ESLint |
How It Works (in plain english)
app.jsstarts an Express server on port 8080- It spawns
refresh.jsas a child process refresh.jsreadsconfig.json, loops through thecontributorsarray, and calls the GitHub API for each one- Results are written to
src/assets/data/data.json - The frontend fetches
/dataendpoint which servesdata.json - Real-time updates via socket.io
- The API endpoints (
/api/stats,/api/rank,/api/contributor) read from the samedata.json
Critical Design Decisions
Hidden Rank Column
The rank column and some aggregate stats are rendered with invisible/white text. This is intentional — admins can select-all and copy the table to get full stats in one stroke. Do not "fix" this visibility.
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.
