atelier-pipeline: Instructions file for Claude Code

CLAUDE.md

atelier-pipeline CLAUDE.md is an instructions file for Claude Code from robertsfeir/atelier-pipeline. It costs 1,118 tokens per session, scanned A, original, Apache-2.0.

Project instructions for Atelier Pipeline, a system that coordinates several AI coding agents in Claude Code and Cursor. They describe its tools, source layout, tests, and coding conventions.

In plain words
What is it for?
Use them when modifying Atelier Pipeline, especially when working with its agent files, hooks, slash commands, shared templates, or Claude Code and Cursor plugin packaging.
Why use it?
They give coding agents shared rules and quality checks, reducing inconsistent changes and unclear project practices across two development tools.

This is robertsfeir/atelier-pipeline's own configuration. It tells Claude Code how to work on atelier-pipeline 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 atelier-pipeline 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

atelier-pipeline 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 10d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Atelier Pipeline

Multi-agent orchestration system for AI-powered IDEs (Claude Code + Cursor). Quality gates and continuous QA. Persistent institutional memory is provided by the separate mybrain plugin (optional; install alongside this plugin).

Tech Stack

  • Hooks/Enforcement: Bash shell scripts (PreToolUse hooks)
  • Agent System: Markdown persona files, slash commands, orchestration rules
  • IDE Support: Claude Code plugin + Cursor plugin (dual-target from shared source)
  • Plugin System: Claude Code plugin format (.claude-plugin/plugin.json), Cursor plugin format (.cursor-plugin/)

Test Commands

  • pytest tests/ -- full test suite
  • echo "no linter configured" -- linter
  • echo "no typecheck configured" -- type checker

Source Structure

Source templates are split into three directories: source/shared/ (platform-agnostic content), source/claude/ (Claude Code overlays with frontmatter and hooks), and source/cursor/ (Cursor overlays). Agent files are assembled at install time by combining platform-specific frontmatter overlays with shared content bodies.

  shared/        # Platform-agnostic content (no YAML frontmatter)

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.
