# CI Workflow Authoring

> CI Workflow Authoring is an Agent Skill for devops & security published in the camunda/camunda repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Authors and refactors GitHub Actions workflows and composite actions for this monorepo using required conventions, minimal permissions, pinned SHAs, and observability steps. Use when creating or restructuring CI workflows.

## SKILL.md

# CI Workflow Authoring Skill

Check `docs/monorepo-docs/ci.md` first.

## Required Workflow Conventions

- Include metadata comments (`description`, `test location`, `type`, `owner`).
- Set default shell to bash.
- Start with `permissions: {}` and add only required scopes.
- Add `timeout-minutes` per job.
- Pin all external actions to commit SHAs.
- Ensure each job ends with `observe-build-status` step.
- Fail fast: validate cheap preconditions (required secrets, Vault reachability, input/tag contracts) in a preflight step or job before expensive build/test steps.

## Unified CI Criteria

- Runtime <= 30 minutes
- Stable and observable
- Vault-based secret handling
- Uses approved cache strategy

## Caching Strategy

- Maven: `.github/actions/setup-maven-cache`
- npm is the default for Node.js workflows in this monorepo
- Yarn (legacy workflows only): `camunda/infra-global-github-actions/setup-yarn-cache`
- Do not cache Docker layers via GHA cache
- Write caches only from `main` and `stable*`

## Templates

- Workflow template: `references/workflow-template.md`
- Composite action template: `references/composite-action-template.md`
