+
+# Conventional Commit Message Creation
+
+Create properly formatted conventional commit messages following project standards with line length validation and required trailers.
+
+## Purpose
+
+Generate commit messages that:
+
+- Follow conventional commits format (`type(scope): description`)
+- Use component names or GitHub issue numbers as scope
+- Respect line length limits (50 for subject, 72 for body)
+- Include required trailers (Signed-off-by, Assisted-by)
+- Match [Tekton commit message standards](https://github.com/tektoncd/community/blob/master/standards.md#commit-messages)
+
+## Quick Workflow
+
+1. **Analyze changes**: Run git status and git diff to understand modifications
+2. **Determine scope**: Use component name from changed files, or GitHub issue number if available
+3. **Generate message**: Create conventional commit message with proper formatting
+4. **Add trailers**: Include Signed-off-by and Assisted-by trailers
+5. **Confirm with user**: Display message and wait for approval before committing
+
+**CRITICAL**: Never commit without explicit user confirmation.
+
+## Conventional Commit Format
+
+### Structure
+
+```text
+<type>(<scope>): <description>
+
+[optional body]
+
+Signed-off-by: <name> <email>
+Assisted-by: <model-name> (via Cursor)
+```
+
+### Type Selection
+
+Choose the appropriate commit type based on changes:
+
+| Type | Description | Example |
+| ------ | ------------- | --------- |
+| `feat` | New features | `feat(pipeline): add start --output flag` |
+| `fix` | Bug fixes | `fix(taskrun): resolve log streaming race` |
+| `docs` | Documentation | `docs(README): update installation steps` |
+| `refactor` | Code refactoring | `refactor(actions): simplify CRUD helpers` |
+| `test` | Test changes | `test(pipelinerun): add describe unit tests` |
+| `chore` | Maintenance | `chore(deps): update go dependencies` |
+| `build` | Build system | `build(Makefile): add vendor target` |
+| `ci` | CI/CD changes | `ci(github): add golangci-lint action` |
+| `perf` | Performance | `perf(log): optimize pod log streaming` |
+| `style` | Code style | `style(format): run goimports formatter` |
+| `revert` | Revert commit | `revert: undo breaking CLI flag change` |
+
+For complete type reference, see `references/commit-types.md`.
+
+### Scope Rules
+
+#### Priority 1: Component from changed files
+
+Analyze staged files to identify the primary component:
+
+```bash
+git diff --cached --name-only
+```
+
+| File pattern | Scope | Example commit |
+| ------------ | ----- | -------------- |
+| `pkg/cmd/pipeline/*` | `pipeline` | `feat(pipeline): add start --dry-run flag` |
+| `pkg/cmd/task/*` | `task` | `fix(task): resolve list filtering` |
+| `pkg/cmd/pipelinerun/*` | `pipelinerun` | `feat(pipelinerun): add cancel subcommand` |
+| `pkg/cmd/taskrun/*` | `taskrun` | `fix(taskrun): correct log streaming` |
+| `pkg/actions/*` | `actions` | `refactor(actions): simplify CRUD` |
+| `pkg/formatted/*` | `formatted` | `feat(formatted): add JSON output` |
+| `pkg/log/*` | `log` | `fix(log): handle container restart` |
+| `pkg/pods/*` | `pods` | `fix(pods): resolve container lookup` |
+| `pkg/cli/*` | `cli` | `refactor(cli): extract client setup` |
+| `pkg/flags/*` | `flags` | `feat(flags): add --output flag` |
+| `pkg/plugins/*` | `plugins` | `feat(plugins): add discovery logic` |
+| `pkg/version/*` | `version` | `fix(version): correct server detection` |
+| `docs/*` | `docs` or filename | `docs(README): update steps` |
+| `test/*` | component being tested | `test(pipeline): add E2E tests` |
+| `cmd/*` | command name | `feat(tkn): add new subcommand` |
+| Root files | filename | `chore(Makefile): add target` |
+| `AGENTS.md`, `CLAUDE.md` | `docs` | `docs(AGENTS.md): update conventions` |
+
+#### Priority 2: GitHub issue number (optional)
+
+If the work is tracked in a GitHub issue and the user provides one, it can be used as the scope:
+
+```text
+# Branch: fix-123-log-race
+# Scope: #123 or component name
+# Result: fix(log): resolve streaming race condition
+
+Fixes #123
+```
+
+Add `Fixes #NNN` or `Closes #NNN` in the commit body (not the scope) — this is the standard GitHub convention for auto-closing issues.
+
+#### Priority 3: Ask user
+
+If changed files span multiple components or scope is unclear, ask the user which component is the primary focus.
+
+## Line Length Requirements
+
+### Subject Line
+
+- **Target**: 50 characters maximum
+- **Hard limit**: 72 characters
+- **Format**: `type(scope): description` counts toward limit
+- **Tips**: Use present tense, no period at end
+
+```text
+# Good (40 chars)
+feat(pipeline): add start --dry-run
+
+# Too long - exceeds 72 char hard limit
+feat(pipeline): add comprehensive dry-run support with preview output for pipeline start command
+```
+
+### Body
+
+- **Wrap at 72 characters per line**
+- **Blank line** required between subject and body
+- **Content**: Explain why, not what (code shows what)
+- **Format**: Wrap manually or use heredoc in git commit
+
+```text
+feat(pipeline): add start --dry-run
+
+Add dry-run flag to pipeline start command that previews the
+PipelineRun YAML without creating it. Useful for validating
+parameters and workspace bindings before submission.
+
+Signed-off-by: Developer Name <developer@example.com>
+Assisted-by: Claude Sonnet 4.5 (via Cursor)
+```
+
+## Required Trailers
+
+### Signed-off-by
+
+**Always include**: `Signed-off-by: <name> <email>`
+
+This certifies the Developer Certificate of Origin (DCO) — required by tektoncd upstream.
+
+**Detection priority order**:
+
+1. Environment variables: `$GIT_AUTHOR_NAME` and `$GIT_AUTHOR_EMAIL`
+2. Git config: `git config user.name` and `git config user.email`
+3. If neither configured, ask user to provide details
+
+```bash
+echo "$GIT_AUTHOR_NAME <$GIT_AUTHOR_EMAIL>"
+git config user.name
+git config user.email
+```
+
+If neither is configured, ask the user to provide their name and email.
+
+### Assisted-by
+
+**Always include**: `Assisted-by: <model-name> (via Cursor)`
+
+**Format examples**:
+
+```text
+Assisted-by: Claude Sonnet 4.5 (via Cursor)
+Assisted-by: Claude Opus 4.5 (via Cursor)
+```
+
+Use the actual model name (Claude Sonnet 4.5, Claude Opus 4.5, etc.).
+
+## User Confirmation Requirement
+
+**CRITICAL RULE**: Always ask for user confirmation before executing `git commit`.
+
+### Confirmation Workflow
+
+1. **Generate** the commit message following all rules above
+2. **Display** the complete message to the user with separator
+3. **Ask**: "Should I commit with this message? (y/n)"
+4. **Wait** for user response
+5. **Commit** only if user confirms (yes/y/affirmative)
+
+### Example Interaction
+
+```text
+Generated commit message:
+---
+feat(pipeline): add JSON output support
+
+Add --output=json flag to pipeline list and describe commands.
+Uses the existing formatted package JSON helpers.
+
+Signed-off-by: Developer Name <developer@example.com>
+Assisted-by: Claude Sonnet 4.5 (via Cursor)
+---
+
+Should I commit with this message? (y/n)
+```
+
+Wait for user response before proceeding.
+
+## Commit Execution
+
+Use heredoc format for proper multi-line handling:
+
+```bash
+git commit -m "$(cat <<'EOF'
+feat(pipeline): add JSON output support
+
+Add --output=json flag to pipeline list and describe commands.
+
+Signed-off-by: Developer Name <developer@example.com>
+Assisted-by: Claude Sonnet 4.5 (via Cursor)
+EOF
+)"
+```
+
+**Never use**:
+
+- `--no-verify` (skips pre-commit hooks)
+- `--no-gpg-sign` (skips signing)
+- `--amend` (unless explicitly requested and safe)
+

+
+1. **Subject line format**: Must match `type(scope): description` (conventional commits)
+2. **Subject line length**: Target 50 chars, hard limit 72 chars
+3. **No trailing punctuation**: Subject must not end with `.` `!` `?` `,` `:` `;` (exception: `!` for breaking changes like `feat!:`)
+4. **No trailing whitespace**: On any line
+5. **Blank line after subject**: Required before body text
+6. **Body line length**: Wrap at 72 characters per line
+7. **Valid commit type**: Must be one of: `feat`, `fix`, `docs`, `style`, `refactor`, `test`, `chore`, `build`, `ci`, `perf`, `revert`
+8. **Signed-off-by trailer**: Required — `Signed-off-by: Name <email>`
+9. **Assisted-by trailer**: Required when AI assists — `Assisted-by: Model (via Tool)`
+10. **Trailer spacing**: Blank line before trailers, no blank lines between them, no trailing blank lines
+
+## Format standards
+
+Follow [Tekton commit message standards](https://github.com/tektoncd/community/blob/master/standards.md#commit-messages):
+
+- Conventional commit format (`type(scope): description`)
+- Subject line: target 50 characters, hard limit 72
+- Body lines wrapped at 72 characters
+- Required `Signed-off-by` trailer (DCO)
+- No trailing punctuation on the subject
+
+## Auto-Detection Summary
+
+When generating commit messages:
+
+1. Run `git status` (without -uall flag)
+2. Run `git diff` for staged and unstaged changes
+3. Identify primary component from staged file paths
+4. If scope unclear, ask user
+5. If user mentions a GitHub issue number, add `Fixes #NNN` to body
+6. Analyze staged files to determine commit type
+7. Generate appropriate scope and description
+8. Detect author info from environment variables or git config
+9. Ensure subject line is ≤50 characters (max 72)
+10. Wrap body text at 72 characters per line
+11. Add required trailers (Signed-off-by and Assisted-by)
+12. Format according to conventional commits standard
+13. **Display message and ask for user confirmation**
+14. Only commit after receiving confirmation
