What is Opensource-Contribution-Leaderboard GEMINI.md?

A project guide for an open-source contributor leaderboard that tracks pull requests and issues across GitHub repositories. It describes the application structure, setup, configuration, and deployment path.

Use it to understand the frontend, server, refresh worker, GitHub API integration, configuration file, and Node.js deployment process.

It gives developers the project context and setup details needed to maintain or deploy the leaderboard.

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	$0.00869	$0.00869
Opus 5.5	$0.00348	$0.00348
Sonnet 5.5	$0.00174	$0.00174
Haiku 4.5	$0.00087	$0.00087

Security

Grade A, and why

Opensource-Contribution-Leaderboard GEMINI.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.

Gemini AI Context — Opensource Contribution Leaderboard

What This Project Is

A real-time open source contributor leaderboard. It tracks PRs (open + merged) and issues across a GitHub organization's repositories. Uses Node.js, Express, and vanilla frontend.

Built originally for Rocket.Chat's GSoC contributor tracking, but works for any GitHub organization.

Project Architecture (keep it simple)

index.html          ← frontend (vanilla HTML, rendered via webpack)
src/index.js        ← frontend JS entry point (axios + socket.io-client)
src/server/app.js   ← Express server (serves static files + proxies API + spawns refresh)
src/server/refresh.js ← background worker that polls GitHub API and writes data.json
src/server/config.json ← YOUR config (copy from config-example.json)
src/server/util/API.js  ← GitHub API calls
src/server/util/Util.js ← helper utilities
admin/              ← admin panel (separate webpack build)

Deployment — The Only Path That Matters

There is exactly one deployment path. Plain Node.js.

git clone <repo-url>
cd Opensource-Contribution-Leaderboard
cp src/server/config-example.json src/server/config.json
# Edit src/server/config.json — add your GitHub auth token, org name, contributors
npm run add       # installs deps for root + server + admin
npm run build     # builds frontend + admin panel
cd dist/server
node app.js

Runs on port 8080. That's it.

For local development:

npm start         # webpack-dev-server on :8080
npm run serve     # backend on :62050 (in a second terminal)

Config

Static/environment settings live in .env (copy from src/server/.env.example):

AUTH_TOKEN=ghp_...              # GitHub personal access token
ORGANIZATION=YourOrg             # GitHub org name
ORGANIZATION_HOMEPAGE=https://yourorg.com/
ORGANIZATION_GITHUB_URL=https://github.com/YourOrg
ADMIN_PASSWORD=change-this       # admin panel password
SERVER_PORT=62050                # backend API port

Dynamic/runtime values stay in config.json (modifiable via admin panel):

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.
