How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/camunda/camunda/blob/HEAD/.claude/skills/ci-workflow-authoring/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ci-workflow-authoring, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

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
