CLAUDE.md

coding-with-ai-lab CLAUDE.md is an instructions file for Claude Code from atra-consulting/coding-with-ai-lab. It costs 3,551 tokens per session, scanned A, original, MIT.

A project instruction file for a coding project that tells Claude Code where shared project knowledge lives and lists specialist agents for planning, operations, reviews, backend, database, frontend, testing, and design work.

In plain words
What is it for?
Use it to configure Claude Code for that project and direct different tasks to the appropriate planning, coding, testing, or review agent.
Why use it?
It gives the coding agent a consistent map of project rules, reference files, and available specialist roles before it starts work.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is atra-consulting/coding-with-ai-lab's own configuration. It tells Claude Code how to work on coding-with-ai-lab itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything coding-with-ai-lab configures →

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

coding-with-ai-lab 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 9d 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.

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Project knowledge for Claude Code and GitHub Copilot CLI. Claude Code loads this file. Copilot CLI loads it too (next to AGENTS.md, which only points here). Keep tool-neutral wording here.

Project

Full-stack CRM application. Node.js/TypeScript (Express + Drizzle ORM + libSQL/SQLite via @libsql/client) backend, Angular 21 frontend. German domain model: Firma, Person, Abteilung, Adresse, Aktivitaet, Chance. Local SQLite file at backend/data/crmdb.sqlite; production runs on Turso cloud when TURSO_DATABASE_URL is set. Authentication via hardcoded users (backend/src/config/users.ts, bcrypt-hashed passwords), session-based and persisted to the sessions table (LibsqlSessionStore). 3 users: admin/admin123 (ADMIN), user/test123 (USER), demo/demo1234 (ADMIN). Enforcement is role-based via requireRole('ADMIN'); users also carry a permissions array, but no requirePermission middleware is wired up.

Autonomous Agents (advanced workshop)

Two independent CI agents. Each runs Claude Code or Copilot CLI (engine input, default claude). Both are documented in full in docs/specs/SPEC-API-TASKS.md.

  • Agent-task runner — drains the agent_task table (sources EMAIL, GITHUB_ISSUE, APP_LOG, ERROR_REPORT; lifecycle OPEN → IN_PROGRESS → DONE | REJECTED) via the /api/agent-tasks API, decides solve-or-reject, implements, and merges. Admin dashboard at /admin/agent-tasks. Workflow .github/workflows/agent-task-runner.yml, prompts .claude/prompts/agent-*.md.
  • GitHub-issue agent — works real GitHub issues labelled Refinement needed, one per run, triggered from the solve-github-issues card in /admin/cron. Implements-or-asks; opens a PR against main (never merged) or comments a question and adds Input needed. Status tracked on GitHub Project board #7. Workflow .github/workflows/github-issue-agent.yml, prompt .claude/prompts/agent-github-refinement.md.

Agent endpoints authenticate with requireAgentToken (AGENT_API_TOKEN); cron triggers with requireCronAuth (CRON_SECRET or admin session). See docs/specs/SPEC-API-TASKS.md for endpoint signatures, required secrets, and board mechanics.

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.
