github-actions-cicd

A set of conventions for GitHub Actions, a service that runs automated software jobs from a repository.

In plain words
What is it for?
Use it when writing, reviewing, or debugging workflow files, including job structure, caching, permissions, secrets, pinned actions, and deployment environments.
Why use it?
It helps make build, test, security, and deployment workflows easier to maintain and safer to run.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

github-actions-cicd scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

GitHub Actions CI/CD Conventions

Workflow Structure

  • Split logically distinct phases into separate jobs (build, test, lint, security scan, deploy) rather than one monolithic job [web:66][web:64].
  • Split deployment targets into separate workflows or jobs per environment (dev/staging/prod) with explicit GitHub Environments and required approvals for prod [web:65].
  • Keep workflows simple; add complexity incrementally rather than front-loading a complex pipeline [web:65].
  • Parallelize independent jobs to reduce total pipeline time [web:65].

Caching and Performance

  • Cache dependencies (npm/NuGet/pip) and build artifacts between runs using actions/cache [web:65].
  • Reuse composite actions or reusable workflows for logic repeated across pipelines instead of copy-pasting steps.

Security

  • Store all credentials and API keys in GitHub Secrets, never in workflow YAML or committed files [web:65].
  • Restrict third-party actions to pinned versions (commit SHA or exact tag), not floating @main/@latest.
  • Avoid self-hosted runners on shared/production infrastructure; isolate them in a dedicated environment [web:60].
  • Scope GITHUB_TOKEN permissions to the minimum required (permissions: block) rather than defaulting to full write access.

Deployment

  • Use GitHub Environments with protection rules for staging/production deploys, requiring manual approval for prod [web:65].
  • Fail fast: run lint/test/security jobs before the deploy job, and make deploy depend on their success (needs:).

When Reviewing or Debugging

Check for: unpinned action versions, secrets exposed in logs or run: commands, missing needs: dependencies that let deploy run before tests pass, and overly broad token permissions — these are higher priority than formatting nits.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

github-actions-cicd is a skill published in the GitHub repository NicoGenti/opencode-orchestrator-kit (5 stars, last pushed 3d ago), licensed MIT. It adds 33 tokens to every session and 425 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
