A set of project-specific instructions for working on the maf-doctor repository, including required checks before pushing and known build and shell problems.

In plain words
What is it for?

Why use it?
It gives contributors the repository's local rules and troubleshooting steps instead of leaving them to discover them through failed builds or CI runs.

Instructions file for Claude Code

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

This is joslat/maf-doctor's own configuration. It tells Claude Code how to work on maf-doctor 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 maf-doctor 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

maf-doctor 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 21d 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Read AGENTS.md first: it maps the codebase, the self-update loop, and the coding standards. These are working notes on top of it.

Before pushing

CI minutes and Copilot credits are limited. Run the gates locally so CI confirms rather than debugs:

dotnet test src/maf-autopilot.Tests/maf-autopilot.Tests.csproj -c Release -f net10.0
python3 -m pytest .github/scripts/tests -q
python3 .github/scripts/verify_crossfile_consistency.py
MAF_REGISTRY_PATH="$PWD/.github/skills/maf-obsolete-api-registry/registry.yaml" \
  dotnet src/maf-autopilot/bin/Release/net10.0/maf-doctor.dll verify-registry

When registry entries change, also compile their examples against the real packages (needs nuget.org; the release and the one before it must be in the train lock):

python3 .github/scripts/verify_registry_examples.py --old-version 1.22.0 --version 1.23.0 \
  --maf-doctor "dotnet src/maf-autopilot/bin/Release/net10.0/maf-doctor.dll"

Batch commits on one branch and keep one PR open at a time.

Gotchas

  • Build in Release. A running maf-doctor MCP server locks the Debug output. On Windows add -nodeReuse:false -p:UseSharedCompilation=false to avoid idle MSBuild nodes.
  • Doctor_ValidPath_ExitsZero can fail locally when %TEMP% is polluted; filter it out (--filter "FullyQualifiedName!~Doctor_ValidPath_ExitsZero").
  • Git Bash: prefix git show ref:path with MSYS_NO_PATHCONV=1. To run dotnet-inspect from Python on Windows, pass dotnet-inspect.cmd.
  • Escapes: writing C#, YAML or Python through a shell heredoc can turn \n and \-newline into literal line breaks. Use an editor tool for escape-heavy edits.
  • Unquoted YAML scalars in registry.yaml must not contain : ; quote them.
  • Diff from the merge-base (base...head) in PR gates. A two-dot diff against an advanced main attributes main's changes to the PR.
  • Watcher scaffold PRs (release-watcher/maf-*) must keep linear history and may only touch data paths; never merge main into them. To re-run their checks on a fresh merge ref, push a commit to the branch.

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.
