# submit-commit-cleanup-artifact ## Overview A commit cleanup is one markdown document (`artifact_type: "commit_cleanup"`) recommending which files must NOT be committed: binaries, build artifacts, editor temp files, machine-local configuration. Submit with `ralph_submit_md_artifact`; pre-check with `ralph_verify_md_artifact`. ## Document Shape Frontmatter: `type: commit_cleanup` and `analysis_complete: true` or `analysis_complete: false` (exactly those lowercase words). | Section | Required | Items | |---|---|---| | `## Actions` | yes (may have zero items) | `<action> \| <path-or-pattern>` per item | | `## Reason` | no | at most 1: why these actions | Each action item text is `<action> | <value>` with a space-pipe-space separator: - `delete_file | <path>` — remove a file from the repo. Only for actual binary/generated files in the diff or paths on the Ralph runtime-artifact allowlist. - `add_to_gitignore | <pattern>` — project-wide patterns like `*.pyc`, `build/`, `dist/`. - `add_to_git_exclude | <pattern>` — machine-local patterns like `.env.local`, `.vscode/`. Never use `delete_file` for environment files. Paths and patterns must be printable ASCII: no control characters, no whitespace-only values, no non-ASCII, and no leading `#` (a `#` prefix would silently disable a real `.gitignore` / `.git/info/exclude` rule via comment-line injection — the validator rejects it on purpose). ## Security Boundary (keep these semantics) The runtime enforces a path boun
