Use a single regex in a workflow to enforce naming discipline:

**Non-release branches:**

```regex
^(feat|fix|hotfix|refactor|chore|docs|test|perf|ci|build|deps|security|revert|research|design|a11y|ux|i18n|ops|proto|ds|api|schema|telemetry|content|seo|config|migrate|qa|uat|audit|codex)/[a-z0-9]+(?:-[a-z0-9]+)*-[a-z0-9]+(?:-[a-z0-9]+)*$
```

**Release branches (semantic versioning):**

```regex
^release/v?\d+\.\d+\.\d+(-[a-z0-9]+)*$
```

**Release branches (standard format):**

```regex
^(feat|fix|hotfix|release|refactor|chore|docs|test|perf|ci|build|deps|security|revert|research|design|a11y|ux|i18n|ops|proto|ds|api|schema|telemetry|content|seo|config|migrate|qa|uat)/[a-z0-9._-]+$
^release/[a-z0-9]+(?:-[a-z0-9]+)*-[a-z0-9]+(?:-[a-z0-9]+)*$
```

**For exact patterns, see the authoritative validator:** `scripts/validation/validate-branch-name.cjs` (lines 66-78)

### 4.1 Forbidden Prefixes (AI Agent Governance)

The following prefixes are **strictly forbidden** for all branches to enforce proper governance of AI-assisted development:

- `claude/` — Reserved for governance audits only; blocks automated routing
- `copilot/` — GitHub Copilot-specific branches not permitted
- `openai/` — OpenAI-related work must use appropriate type prefixes

**Rationale:** Forbidden prefixes act as circuit-breakers for AI agents (Claude Code, GitHub Copilot). When detected, they trigger fallback routing to default PR templates and prevent type-based automation. This ensures:

- AI agents cannot bypass branch naming governance
- Explicit type prefixes drive proper automation routing
- Governance audits are tracked and auditable
- No silent acceptance of non-conforming branch names

**Enforcement:** CI will reject any branch matching `claude/`, `copilot/`, or `openai/` prefixes, even if followed by valid scope-title patterns.

- For monorepos, ensure branch naming applies to each package/subproject, or use a consistent prefix (e.g. `feat/frontend-...`, `fix/api-...`).
- For forked repos, always clean up branches after merging upstream PRs, and avoid duplicating branch names across forks to prevent confusion.

### 4.3 PR Template Routing & Fallback Behavior

PR template selection is automatically routed based on branch type prefix:

| Branch Type | PR Template |
|---|---|
| `feat/` | `pr_feature.md` |
| `fix/` | `pr_bug.md` |
| `hotfix/` | `pr_hotfix.md` |
| `release/` | `pr_release.md` |
| `refactor/` | `pr_refactor.md` |
| `chore/` | `pr_chore.md` |
| `docs/` | `pr_docs.md` |
| `ci/` | `pr_ci.md` |
| `deps/` | `pr_dep_update.md` |
| `audit/` | `pr_chore.md` (governance review) |
| `codex/` | `pr_docs.md` (knowledge base) |
| Other types | `pr_chore.md` (default) |
| Forbidden prefixes | `pr_chore.md` (fallback) |
Comment thread
coderabbitai[bot] marked this conversation as resolved.

**Fallback Logic:** If a branch uses a forbidden prefix (e.g., `claude/governance-audit-implementation`), the PR template resolver detects the violation and routes to the default `pr_chore.md` template. This ensures:

- No PR is left without template guidance
- Forbidden prefixes trigger visible fallback routing (auditable)
- Authors are prompted to re-open PR with proper branch naming
- Type detection hierarchy: branch type → linked issue type → default

Align the documented fallback with the resolver workflow.

The resolver does not check the branch prefix and does not read .github/PULL_REQUEST_TEMPLATE/config.yml. For claude/ and copilot/ branches, it resolves the linked type and defaults to pr_feature.md; openai/ does not trigger the workflow. Update this section to match the workflow, or implement the documented pr_chore.md fallback.
