# action/check-naming

Composite Gitea Action that validates a pull request's head branch name
and title against the fritzlab naming standard. `@v2` fails (exits 1) on
any violation; `@v1` is the legacy warn-only release that never fails
(Bugs program: see
[fritzlab/agenthub#557](https://code.fritzlab.net/fritzlab/agenthub/issues/557)).

## Standard

```
Branch:   <role>/bug-<id>/<kebab-description>     e.g. dev/bug-x7k2m9/fix-terminal-resize
Chore:    chore/<kebab-description>               bug-less trivia only (dep bumps, typos, CI tweaks)
Title:    [bug-x7k2m9] Fix terminal resize loss   (chore PRs: no [bug-id] prefix)
```

- `<role>` must be a roster handle: `dev` | `ux` | `ops` | `security` | `perf` | `architect` | `support`
- `<bug-id>` is `bug-` followed by lowercase alphanumeric characters
- `<kebab-description>` is lowercase alphanumeric with hyphens, starting with a letter or digit
- When both the branch and the title carry a bug-id they **must match**
- Break-glass: PRs authored by `dfritz` are exempt from all checks

## Usage

```yaml
jobs:
  naming:
    runs-on: fritzlab
    timeout-minutes: 5
    steps:
      - uses: https://code.fritzlab.net/action/check-naming@v2
        with:
          head-branch: ${{ github.head_ref }}
          pr-title: ${{ github.event.pull_request.title }}
          pr-author: ${{ github.event.pull_request.user.login }}
```

To wire a new repo warn-only first, add `continue-on-error: true` to the
job — the step still fails, but the job cannot block the PR.

## Inputs

| Name | Required | Description |
|---|---|---|
| `head-branch` | yes | Head branch name — `github.head_ref` |
| `pr-title` | yes | PR title — `github.event.pull_request.title` |
| `pr-author` | no | PR author login — `github.event.pull_request.user.login`; `dfritz` is exempt |

## Behavior

The check validates two things:

1. **Branch form** — must be `<role>/bug-<id>/<kebab>` or `chore/<kebab>`.
   Unknown roles, missing `bug-` segment, uppercase bug-ids, and empty
   kebab descriptions all produce a `FAIL[check-naming]` log line.

2. **Title form** — for a `role/bug` branch the title must start with
   `[bug-<id>] `. For a `chore` branch the title must have no `[bug-id]`
   prefix. If both carry a bug-id they must match.

Every violation prints a `FAIL[check-naming]: ...` line and the step
exits 1. To make the check required on a repo: drop any
`continue-on-error: true` from the consuming workflow and add the job's
context to the repo's `status_check_contexts` in agenthub `hub/hub.yaml`.

## Versions

- `v2` — enforcing: exits 1 on violation (current).
- `v1` — legacy warn-only: logs `WARN` lines, always exits 0.
