mvmt: Instructions file for Claude Code

CLAUDE.md

mvmt CLAUDE.md is an instructions file for Claude Code from philipnee/mvmt. It costs 712 tokens per session, scanned A, original, MIT.

Project instructions for coding agents working on mvmt, a local-first hub that collects data through the Model Context Protocol.

In plain words
What is it for?
Use them when making changes in mvmt to understand the project context, avoid unrelated edits, and run the required verification command.
Why use it?
They set boundaries for keeping code changes small and require checks before work is declared complete.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions Claude Code; mentions Codex.

This is philipnee/mvmt's own configuration. It tells Claude Code how to work on mvmt 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 mvmt 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

mvmt 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.

Agent Rules

This file is the entry point for any AI coding agent working on mvmt. If you are Claude Code, Codex, Cursor, Copilot, or any other coding agent, read and follow these rules before making any changes.

Project context

mvmt is a local-first MCP data hub. Read README.md for what it does, docs/architecture.md for how it works, and CONTRIBUTING.md for development setup and the test matrix.

Rules

1. Keep diffs small and reviewable

  • One concern per commit. Do not bundle unrelated changes.
  • Prefer editing existing files over creating new ones.
  • Do not refactor, rename, reformat, or add comments to code you are not changing for the task at hand.
  • Do not add speculative features, abstractions, or configurability beyond what was requested.
  • If a change touches more than ~5 files or ~150 lines, stop and break it into smaller steps.

2. Run verification before declaring done

Run:

npm run verify

This is the PR gate. It runs the TypeScript build, full test suite, whitespace checks, package dry-run, and a runtime smoke test.

Coverage requirements:

  • 100% feature coverage: every behavior your change introduces or modifies must have a test that exercises it, including error/rejection paths.
  • 80% spatial coverage: at minimum 80% of the lines you added or changed must be hit by at least one test. Run npm run test:coverage to check.

Do not skip verification. Do not report a task as complete without showing that verification passed.

3. Security-sensitive changes need extra tests

If your change touches any of these areas, add focused tests for both the success and failure/rejection paths:

  • Token generation or validation
  • OAuth/PKCE flow
  • Origin checks
  • Write gates
  • Filesystem path validation (traversal, symlinks)
  • Environment scrubbing
  • Audit logging
  • Connector process spawning or shutdown

Default to less access. Require explicit user consent for writes.

4. PR description format

Every pull request must include:

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.
