What it does

GitHub Actions Performance is an agent skill from AliceJump/ok-end-field. Diagnose slow GitHub Actions jobs in ok-script repos, especially checkout history/tags and partial-sync-repo tag pruning. Use when attributing a sync job speed change or reducing repeated tag work.

Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering CI/CD. It works with GitHub Actions. The repository describes itself as: 终末地 End Field Automation 基于ok-script开发的自动化. The licence is AGPL-3.0.

What it can do on your machine

Read from SKILL.md and the folder at commit a8af4e8. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

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

Context cost

GitHub Actions Performance loads about 439 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 218 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~439

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

GitHub Actions Performance

Verified ok-end-field sync case

ChangeObserved effect
37593fa added fetch-depth: 0 and fetch-tags: true~9–11 min to ~3 min
e1125be upgraded actions/checkout@v4 to @v6~3 min to ~1.4 min

The old shallow checkout saw only tags reachable from its single commit. ok-oldking/partial-sync-repo compared that incomplete source set with target tags and deleted about 304 apparently “missing” tags at roughly 2 seconds each. The tags existed in the source repository; they were not orphans. Full history plus tags stopped that work. The later checkout upgrade sped up the full fetch.

Diagnose another run

  1. Get the job log and measure its first/last timestamps; old jobs API startedAt / completedAt can be null. Count Deleting tag lines to see whether pruning dominates.
  2. Tie each compared run's head_sha to the exact workflow/action version and tag state. Separate a persistent code/version improvement from a one-time cleanup.
  3. Check the action's behavior before changing options: it clones target repositories, syncs listed files, and then synchronizes tags. When no files change, its early continue skips tag synchronization for that target. It has no “push new tag but keep all old tags” option; that requires a fork or custom commands.

Pin partial-sync-repo to a reviewed full commit SHA rather than @master when modifying the workflow. Validate YAML and Actions structure with $github-workflows.
