Deployment Composer

Deployment Composer

Compose the smallest safe deployment workflow from the repository's actual branching model, CI setup, deploy provider, and release risk. Routes work to focused skills instead of treating every deploy as the same checklist.

Authorized Scope

Apply this engine only within the user's requested task and existing explicit authorization. Loading or delegating to it grants no additional authority. Preserve report-only restrictions and the caller's target, host, provider, and cost limits. Existing approval satisfies a gate only for the same actions and scope; obtain approval before expanding them. Forward these limits to delegates.

Contract

Inputs:

• Repository root
• Desired release/deploy goal
• Optional target environment, source branch, target branch, PR number, or provider

Outputs:

• Deployment route: release PR, provider deploy, CI setup, or repair
• Selected delegated skills
• Quality gate state
• Confirmation gates still required

Creates/Modifies:

• Nothing during discovery
• May create local release notes or PR body files
• May create GitHub PRs only through release-pr-gates after confirmation rules are satisfied

External Side Effects:

• Reads git/GitHub metadata and workflow status
• May trigger provider deployment commands through delegated skills

Confirmation Required:

• Before production deploys or merges
• Before creating GitHub PRs when the user did not explicitly request PR creation
• Before running provider commands with production flags

Delegates To:

• release-pr-gates
• deploy
• github-fix-ci
• ec2-backend-deployer
• testing-cicd-init
• changelog-generator

Composed Skills

Discovery Phase

Always inspect before choosing a path:

git status -sb
git remote -v
git branch -r
find . -maxdepth 3 -type f \( -name 'package.json' -o -name 'vercel.json' -o -name 'Dockerfile' -o -name 'docker-compose.yml' -o -name 'docker-compose.yaml' -o -name 'turbo.json' \)
find .github/workflows -maxdepth 1 -type f 2>/dev/null

For GitHub repos:

gh repo view --json nameWithOwner,defaultBranchRef
gh workflow list

Capture:

• Current branch and dirty worktree state
• Default (trunk) branch and remote branch list
• CI provider and required checks
• Deploy provider: Vercel, EC2/Docker, GitHub Actions, custom scripts, or unknown
• Package manager and quality commands
• Environment targets: preview, staging, production

Routing Rules

Release

If the user wants to cut a release:

1. Use release-pr-gates to gate the release on the trunk (default branch).
2. A short-lived feature or fix branch is merged into the trunk via PR; the release is then cut from the trunk as a semver tag + GitHub release.
3. staging and production are deployment environments driven by CI/tags — not git branches.
4. Wait for quality gates before calling the release ready.
5. Use github-fix-ci if checks fail.

Direct Provider Deploy

If the user wants to deploy the current branch/app to an environment:

1. Use deploy for local pre-deploy checks and post-deploy verification.
2. Route provider setup or execution:
   • Vercel project: use Vercel-specific guidance or CLI.
   • EC2/Docker backend: use ec2-backend-deployer.
   • Turborepo: inspect turbo.json and use affected builds where appropriate.
   • Unknown provider: inspect scripts and workflow files before acting.
3. Do not deploy production without explicit confirmation.

CI Setup or Repair

If the repo has no CI or weak gates:

1. Use testing-cicd-init to add baseline checks.
2. Use deploy after CI exists.
3. For failing existing checks, use github-fix-ci.

Release Notes

If the release needs user-facing notes or a PR body:

1. Use changelog-generator for commit summaries.
2. Include migrations, env changes, and rollback notes when visible.

Deployment Workflow

1. Discover repo topology and deployment provider.

2. Choose the narrowest route from the routing rules.

3. Run local gates before every release PR or deployment. Format, lint, and type-check are mandatory:

   bun run format || npm run format || npx biome check --write .
   bun run lint || npm run lint || bunx turbo lint
   bun run typecheck || bun run type-check || npm run typecheck || npm run type-check || npx tsc --noEmit
   bun run test || npm test
   bun run build || npm run build
   

   Fix format, lint, and type-check failures before pushing or deploying. Tests and build should run when configured; report absent scripts as coverage gaps.

4. Execute the selected release or deploy path.

5. Wait for remote checks or deployment status.

6. Verify the deployed environment:

   • health endpoint
   • critical page/API path
   • logs or monitoring when available

7. Report final status and blockers.

Safety Rules

• Never hide a dirty worktree; identify whether local changes are part of the deploy.
• Never bypass branch protection or required checks.
• Never merge or deploy production without explicit confirmation.
• Never assume a staging environment is configured; verify CI/deployment settings.
• Never call skipped or absent checks green.
• Prefer existing repo scripts and workflows over inventing new deploy commands.
• If a provider cannot be identified, stop after discovery and report what is missing.

Output Shape

Return a compact deployment state:

Deployment route: [release PR / provider deploy / CI setup / repair]
Repository: [owner/repo]
Branches: [source] -> [target] or [current branch]
Provider: [Vercel/EC2/Docker/GitHub Actions/custom/unknown]
Checks: [passing/failing/pending/not configured]
Deployment: [not started/in progress/succeeded/failed]
Verification: [passed/failed/not available]
Needs confirmation: [production merge/deploy, if applicable]
