helixir CLAUDE.md

Project-specific rules for AI coding agents working on the Helixir codebase. They define safety requirements, verification steps, and when agents must ask a person to take over.

In plain words
What is it for?
They guide agents when reading files, editing code, installing packages, running quality checks, committing changes, and reporting the current project state.
Why use it?
They reduce the risk of skipped checks, exposed secrets, unsafe Git operations, or unverified claims about the project. They also protect the project's attribution policy.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

helixir 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 3d 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.

Agent Behavioral Rules

Non-Negotiable Rules

These rules are enforced by hooks and cannot be overridden by any agent instruction:

  • NEVER use --no-verify to skip git hooks — hooks are safety gates, not obstacles
  • NEVER commit secrets, credentials, API keys, or tokens to any file
  • NEVER force-push to main, master, staging, or production branches
  • NEVER push without all applicable quality gates passing (run pnpm preflight or equivalent)
  • NEVER install packages without verifying they exist in the npm registry first

Verification Requirements

  • Read files before editing them — understand existing code before modifying
  • Verify package existence before installing: npm view <package> or check npmjs.com
  • Confirm current state before claiming status — check git, files, build output
  • Check tool availability before assuming it is installed

Attribution

Do NOT include AI attribution in commits, PR bodies, code comments, or any content. When block_ai_attribution is enabled in .rea/policy.yaml, the commit-msg hook REJECTS commits containing structural AI attribution (Co-Authored-By with AI names, 'Generated with [Tool]' footers, etc.). The attribution-advisory hook also blocks gh pr create/edit and git commit commands with attribution. You must remove all attribution markers before committing — the hooks will NOT silently fix them.

Human-in-the-Loop Escalation

When you encounter an unexpected blocker, ambiguous requirement, or situation not covered by the current context:

  1. STOP — do not invent a workaround or make assumptions
  2. Describe the situation clearly: what you tried, what failed, what you need
  3. Wait for explicit human instruction before proceeding

The cost of pausing is always lower than the cost of acting incorrectly.

Policy File

Read .rea/policy.yaml at the start of every session to confirm:

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.
