At a glance

Run the full build-and-deploy.yaml workflow locally via act + Docker.

  • Works in 7 steps: Verify prerequisites → Warn about first-run image pull → Ask which build path to simulate → …
  • Tasks that involve Pull requests
  • SKILL.md covers What I do, Critical Constraints, When to use me and Workflow
  • Calls java, mvn and docker; needs GITHUB_TOKEN and CI_DEPLOY_PASSWORD

What it does

CI Act Run is an agent skill from chewiebug/GCViewer. Run the full build-and-deploy.yaml workflow locally via act + Docker. Supports pullrequest and develop snapshot build paths, with configurable DRYRUN.

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: opencode

It sits in Development, covering Pull requests and Containers. It works with Docker, Java and GitHub. The repository describes itself as: Fork of tagtraum industries' GCViewer. Tagtraum stopped development in 2008, I aim to improve support for Sun's / Oracle's java 1.6+ garbage collector logs (including G1 collector).

When your agent uses it

  • Tasks that involve Pull requests
  • Tasks that involve Containers

Example prompts

  • “/ci-act-run”

Requirements

  • Docker
  • A credential in GITHUB_TOKEN
  • A credential in CODECOV_TOKEN
  • Compatibility (from SKILL.md): opencode

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Verify prerequisites
  2. Warn about first-run image pull
  3. Ask which build path to simulate
  4. Ask about DRY_RUN
  5. Ask whether to override the Java matrix version
  6. Execute act
  7. Summarize results

What it can do on your machine

Read from SKILL.md and the folder at commit fe447ec. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • java
    • mvn
    • docker
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use docker and git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • GITHUB_TOKEN
    • CI_DEPLOY_PASSWORD
    • CODECOV_TOKEN
    • ENCRYPTION_PASSWORD
    • SCP_PASSWORD

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    opencode

    From compatibility in the SKILL.md frontmatter.

Context cost

CI Act Run loads about 2.4k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 960 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 960 words (~2,447 tokens).
