Contrib Gate for Pi

Contribution gateway for AI agents — enforce branch naming, conventional commits, pre-commit quality gates, and PR automation. Agents don't call git push — they call contrib_submit().

⚡ Every piece of work must be linked to a Gitea issue. The gate blocks file modifications, commits, and PR creation until an issue is linked via contrib_start_work(issue_id).

Install

pi install npm:@bytesbrains/pi-contrib-gate

Tools

| Tool | What it does | | --------------------------------- | ------------------------------------------- | | contrib_start_work(issue_id) | Create properly named branch, link to issue | | contrib_propose(message, files) | Validate, stage, quality-check, commit | | contrib_submit(title, body) | Push, create PR, return URL | | contrib_status() | Show branch, commits, changes, PR status |

Safety Intercepts

The gate passively monitors all bash tool calls and:

• ⛔ Blocks write/edit operations when no Gitea issue is linked (reminds agent to call contrib_start_work(issue_id) first)
• ⛔ Blocks write/edit on protected branches (main, dev, production)
• ⛔ Blocks contrib_propose() and contrib_submit() when no issue is linked
• ⚠️ Warns on git push --force
• ⚠️ Warns on non-conventional commit messages
• ⚠️ Soft-warns on feature branches without a recognized issue ID
• All blocks can be overridden with user confirmation

Quality Gates

Every contrib_propose() runs:

| Check | Default | Config | | --------------------------------- | ------- | ------------------------- | | Conventional commit format | ✅ | commits.convention | | Max files changed (20) | ✅ | quality.maxFilesChanged | | Max lines added (500) | ✅ | quality.maxLinesAdded | | TypeScript check (tsc --noEmit) | ✅ | quality.typeCheck | | Lint check (npm run lint) | ✅ | quality.lint | | Doctor audit (god file detection) | ✅ | quality.doctorAudit |

Configuration

Create .contribrc.yml in your project root (created automatically on first use with defaults):

# Remote configuration (optional — auto-detects by default)
remote.name: "" # Explicit remote name (e.g., "gitea", "origin")
remote.type: auto # "gitea" | "github" | "auto" — skip platform detection
remote.url: "" # Override API base URL for custom/self-hosted Gitea
remote.token: "" # Gitea PAT for API calls (required for SSH remotes)

branches.featPattern: feat/
branches.fixPattern: fix/
branches.chorePattern: chore/
commits.convention: conventional
commits.maxSubjectLength: 72
quality.maxFilesChanged: 20
quality.maxLinesAdded: 500
quality.lint: true
quality.typeCheck: true
quality.doctorAudit: true

Remote Configuration

When a repository has both gitea and origin (GitHub) remotes, agents can get confused about which platform to use. The remote section resolves this ambiguity.

| Key | Default | Description | | -------------- | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | remote.name | "" (auto) | Explicit remote name for push/pull. When unset, auto-detects from available remotes. | | remote.type | "auto" | Platform type. "gitea" skips GitHub API queries, "github" skips Gitea API queries, "auto" detects from remote URL. | | remote.url | "" (default) | Base URL for Gitea API (e.g., "https://gitea.mycompany.com"). Only needed for custom/self-hosted instances. | | remote.token | "" | Gitea personal access token. Required when using SSH remotes (git@gitea:...) since SSH URLs don't contain credentials. HTTP remotes with embedded PATs take priority over this value. |

SSH Remote Setup Example:

remote.name: gitea
remote.type: gitea
remote.token: your-gitea-pat-here

⚠️ Security: The token is never included in logs, error messages, or debug output. If .contribrc.yml is committed to your repo, add it to .gitignore or use an empty remote.token and rely on a URL-embedded PAT or environment-level credential store instead.

Example Workflow

→ contrib_start_work(issue_id="7", type="feat")
✅ Work started on feat/issue-7

→ [agent makes code changes...]

→ contrib_propose(message="feat(backup): add Firebase volume backup script", body="Implements daily pg_dump + tar + upload.")
✅ Changes committed (a1b2c3d)

→ contrib_submit(title="feat: automated volume backups to Firebase Storage")
