github-actions-efficiency

github-actions-efficiency is a skill for Claude Code, Codex from drvoss/everything-copilot-cli. It costs 32 tokens per session (1,174 once invoked), scanned A, original, MIT.

An audit of GitHub Actions, the service that runs automated jobs such as tests and builds. It looks for unnecessary runs, inefficient caching, excessive parallel combinations, and workflows that use more runner time than needed.

In plain words
What is it for?
Use it to review workflow triggers, caches, concurrency settings, and build-test matrices, and to produce a before-and-after efficiency report.
Why use it?
It helps reduce wasted CI minutes and costs without removing checks that the project requires. It also identifies triggers that run for changes that do not affect the workflow.

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-efficiency 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Actions Efficiency

Audit GitHub Actions workflow efficiency without weakening required validation. Focus on runner time, wasted runs, broad triggers, and the fastest fixes that actually hold up under review.

When to Use

  • CI minutes are growing faster than the repository's actual change volume
  • Workflows run too often for docs-only, workflow-only, or narrow-scope changes
  • You need to optimize caches, concurrency, trigger scope, or matrix breadth
  • A repository is onboarding GitHub Actions and needs a lean baseline first
  • A team wants a before/after efficiency report grounded in real workflow evidence

When NOT to Use

Instead of github-actions-efficiency Use
Debugging one failed workflow run actions-debugging
Reviewing Actions security risks gha-security-review
Auditing model or token spend across AI workflows cost-audit

Prerequisites

  • Access to .github/workflows/
  • gh CLI access if you want live run data
  • Understanding of which checks are mandatory for release, shared libraries, or migrations

Load Only What You Need

If no workflows exist yet, start with actions.md and define a minimal baseline before trying to optimize.

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.
