What is sap-community-activity-badges CLAUDE.md?

A repository instruction file for working on the SAP Community Activity Badges project. It documents commands, the project structure, startup steps, and important directories for its Node.js service and Vue app.

Use it when changing or running this repository, especially when working with its Express server, Vue frontend, or Vitest tests.

It gives a coding agent the project-specific information needed to install dependencies, run the services, regenerate types, and run tests correctly.

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	$0.01562	$0.01562
Opus 5.5	$0.00625	$0.00625
Sonnet 5.5	$0.00312	$0.00312

Security

Grade A, and why

sap-community-activity-badges 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.

Commands

All development commands are run from the srv/ directory (the Node.js service):

cd srv
npm run install:all     # Install Express deps AND the nested Vue app's deps (one-time per checkout)
npm run dev             # Start Express + Vite dev server (concurrent, ports 4000 and 5173)
npm run dev:server-only # Start Express only (nodemon, port 4000) — when the Vue app isn't needed
npm start               # Start production server (port 4000 by default, overridden by PORT env var)
npm run types           # Regenerate TypeScript declarations in srv/types/
npm run test:vue        # Run the Vue app's Vitest unit tests

Why install:all and not npm install? The Vue SPA at srv/app/profile-vue/ has its own package.json (Vite/Vue/UI5 don't ship to production). Plain npm install in srv/ only handles Express's deps. install:all runs both. We don't use a postinstall hook for security reasons (postinstall scripts are a supply-chain attack vector).

When npm run dev is running, open http://localhost:5173/profile/<scn-id> (Vite's dev server proxies API calls to Express).

To build the MTAR for SAP BTP Cloud Foundry deployment, run from the root:

npm run build        # Builds the Vue SPA, then runs mbt build (requires Cloud MTA Build Tool)

There are no automated tests for the Express service (npm test is a stub). The Vue app has 73 Vitest unit tests; run via npm run test:vue.

Architecture

This is a single Node.js Express 5 service (srv/) packaged as an MTAR for SAP BTP Cloud Foundry deployment. The service generates SVG/PNG image cards showing SAP Community user activity and badges, plus a Devtoberfest contest gameboard.

Requires Node.js ^22.0.0 || ^24.0.0.

Startup Flow

srv/index.js → srv/express-server.js (ExpressServer class):

Loads srv/server/express.js (middleware: logging, CORS, security, Swagger, health check, overload protection)
Auto-loads all srv/routes/**/*.js files as Express route handlers

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.
