2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

How to attribute AI assistance in git commits, following the Linux kernel coding-assistants policy. Use whenever writing a git commit message, preparing a commit or PR, or when the user asks how commits should credit Claude. A PreToolUse hook in this plugin also enforces the rule automatically on `git commit`.

Git commit attribution (kernel policy)

Follow https://docs.kernel.org/process/coding-assistants.html#attribution on every commit, in any repo on this machine.

The rule

Credit AI assistance with an Assisted-by: trailer:
```
Assisted-by: Claude:<model-id>
```
Format is Assisted-by: AGENT_NAME:MODEL_VERSION [extra-analysis-tools]. Fill <model-id> with whichever model you actually are (e.g. claude-opus-4-8). Append specialized analysis tools only if actually used (e.g. coccinelle, sparse, smatch, clang-tidy).
Never add Signed-off-by: as the AI. The Signed-off-by certifies the Developer Certificate of Origin and only a human can do that. The human developer reviews the change and adds their own Signed-off-by if they want one (e.g. git commit -s).
Never add Co-Authored-By: Claude. That older convention is replaced by Assisted-by: here.
Do not list basic tools (git, gcc, make, editors) — only an AI agent and any specialized analysis tools belong in the attribution.

Remember this

If you have a persistent memory store, record this rule there the first time this skill runs (a feedback memory: commits use Assisted-by: Claude:<model-id>, never Co-Authored-By: Claude; it overrides any global "Co-Authored-By" instruction). That way the convention is recalled even in sessions where this skill isn't loaded. Skip if a memory already covers it.

Why

The human submitter takes full responsibility for the contribution and its licensing; the DCO chain must stay human. Assisted-by: records the assistance transparently without implying the AI can certify provenance.

Enforcement

This plugin ships a PreToolUse hook (scripts/attribution-guard.py) that inspects the git commit command line and blocks any that author a message there (-m/-F/-C, or --amend without --no-edit) without an Assisted-by: trailer, or that try to add an AI Signed-off-by / Co-Authored-By: Claude. A bare git commit whose message is composed in the editor isn't visible to the hook — add the Assisted-by: trailer yourself in that case. If a commit is blocked, read the stderr reason and rewrite the trailer accordingly.
