Projects Bot

Purpose. Automates labels and syncs Issues/PRs into GitHub Projects (Status / Priority / Type) across LightSpeed repos. Runs entirely in GitHub Actions using a GitHub App installation token—no external server, no user OAuth.

What it does.

• Applies labels on Issues/PRs (file‑ and branch‑based) and enforces exactly one status:*.
• Adds Issues/PRs to your Project (Beta) and updates Status / Priority / Type from labels & PR branch prefix.
• Nudges PRs without a changelog category via meta:needs-changelog.

Workflows.

• .github/workflows/labels-issues-prs.yml – Issue & PR labelling
• .github/workflows/project-meta-sync.yml – Add to Project + field sync
• .github/labeler.yml – label rules (file globs & branch regex)

Required Project fields. Single‑select options must match these values (or update the workflow mapping):

• Status → Triage, Ready, In progress, In review, In QA, Blocked, Done
• Priority → Critical, Important, Normal, Minor
• Type (optional) → Feature, Bug, Documentation, Task

GitHub App (recommended).

• Org permissions: Projects Read & write.
• Repo permissions: Issues Read, Pull requests Read, Contents Read.
• Secrets/variables:
  • LS_APP_ID (org/repo variable): your App ID
  • LS_APP_PRIVATE_KEY (org/repo secret): your App private key (PEM)
  • LS_PROJECT_URL (org/repo variable): e.g. https://github.com/orgs/LightSpeed/projects/1
• The sync workflow mints an installation token with actions/create-github-app-token@v2 and passes it to the project steps.

PAT fallback (optional). If you can’t use a GitHub App, set LS_PROJECT_PAT (fine‑grained/classic PAT with Projects read/write + Repo read) and change github-token: inputs accordingly.

Security. No webhooks or callback URL required; the App only grants Actions a short‑lived installation token. Keep the private key in Actions secrets.

Troubleshooting.

• 403 on project updates → the App likely lacks Org → Projects: Read & write, or isn’t installed on the repo.
• Items not added to project → check LS_PROJECT_URL and that it’s a Projects (Beta) board, not Classic.
• Labels not applied → ensure .github/labeler.yml exists and patterns match the repo.

Setup Projects Automation

Follow these steps once per organisation; then drop the workflows into any repo that should be automated.

1) Create & install the GitHub App

1. Org Settings → Developer settings → GitHub Apps → New GitHub App.
2. Name it (e.g. LightSpeed Projects Bot). Webhooks/callback not needed.
3. Permissions: Org → Projects Read & write. Repo → Issues Read, Pull requests Read, Contents Read.
4. Generate private key (download .pem).
5. Install the App to the org (all or selected repos).

2) Add Actions secrets & variables

At the org level (recommended) or per repo:

• Variables: LS_APP_ID, LS_PROJECT_URL
• Secrets: LS_APP_PRIVATE_KEY

CLI (example):

3) Create/align Project fields

In your Project (Beta), add single‑select fields with these options:

• Status: Triage, Ready, In progress, In review, In QA, Blocked, Done
• Priority: Critical, Important, Normal, Minor
• Type (optional): Feature, Bug, Documentation, Task

4) Add the workflows & label config

Commit these files to each target repo (or call reusable workflows from .github):

• .github/workflows/labels-issues-prs.yml
• .github/workflows/project-meta-sync.yml
• .github/labeler.yml

5) Protect branches & adopt branch naming

• Protect main and (if used) develop (require PR + review).
• Use prefixes: feat/…, fix/…, docs/…, chore/… (drives the Type field for PRs).

6) Smoke test (5 minutes)

1. Create an issue → should get status:needs-triage, be added to the Project, and have Status Triage.
2. Open a PR from feat/my-change → labeler applies area/lang labels; PR gets status:needs-review; Project fields set (Status In review, Type Feature).
3. Merge the PR → Project Status becomes Done.

7) Roll out at scale

• Put these files in the org .github repo as reusable workflows, or script repo bootstrap with gh.
• Keep labels.yml canonical in .github and sync (optional) via script.

8) FAQ

• Do we need OAuth / callback URLs? No. We use a GitHub App installation token inside Actions.
• Can we use a PAT instead? Yes (fallback), but a GitHub App is safer and org‑wide.
• Classic vs Beta Projects? These workflows target Projects (Beta).
