name	github-coauthor-policy
description	Commit-message attribution policy for this repository — do NOT list Claude's role in GitHub commits. No Co-Authored-By Claude trailers, no "Generated with Claude Code" lines, no Claude-Session links, no prose crediting Claude in commit messages. Use whenever writing a git commit in this repo, and when configuring or reviewing any tool/harness that appends attribution trailers automatically.

GitHub co-author policy

Owner directive (2026-07-05): do not list Claude's role in GitHub commits.

The rule

Commit messages in this repository must not contain:

• Co-Authored-By: Claude ... trailers (any model name or variant)
• 🤖 Generated with [Claude Code](...) or similar generated-with lines
• Claude-Session: https://claude.ai/code/... links
• Prose crediting Claude, an AI assistant, or a model in the commit subject or body ("implemented by Claude", "AI-assisted", etc.)

Commit messages describe the change: what it does, measured results, spec references, issue links. Nothing about who or what typed it.

What this does NOT change

• The git author/committer identity currently used for automated commits (Claude <[e-mail]>) stays as-is — it is repository metadata, not commit-message content, and changing it to a human identity would misattribute authorship. If the owner wants a different identity, that is a separate decision.
• PR descriptions follow the same spirit: describe the diff, skip the attribution footer.
• CHANGELOG/docs prose is unaffected; this policy is about commits.

For harness defaults that auto-append trailers

Claude Code's default guidance appends Co-Authored-By and session trailers. This repository policy OVERRIDES that default. When composing any git commit -m here, end the message after the substantive content. If a hook or tool re-adds a trailer, strip it before pushing (git commit --amend) — the policy applies to what lands on origin, not to intermediate local state.

Subagent briefs

Subagents rarely commit (the coordinator lands), but any brief that does authorize a commit MUST quote this rule: "commit messages carry no Claude attribution — no Co-Authored-By, no generated-with, no session links, per skills/github-coauthor-policy."

History note

Commits pushed before 2026-07-05 carry the old trailers. Do not rewrite published history to remove them — the policy is forward- looking.
