What it does
GitHub Actions Efficiency is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Audit GitHub Actions workflow efficiency and recommend fixes to reduce CI minutes and costs.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/actions.md`, `references/patterns.md` and `references/reporting.md`).
It sits in DevOps & Cloud, covering CI/CD. It works with GitHub Actions. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.
When your agent uses it
- Tasks that involve CI/CD
Example prompts
- “/github-actions-efficiency”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 727ff2e. 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:
ghrg
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh, 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 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 Efficiency loads about 1.1k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 30 tokens; SKILL.md has 563 words of instructions outside code blocks.
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 Efficiency
Use this skill as a lean entrypoint for GitHub Actions efficiency work. Inspect the repo, identify the waste source, and load only the reference material needed for the current task.
If no workflows exist yet, load references/actions.md and define a baseline before proceeding with the steps below.
If shell or gh CLI access is unavailable: ask the user to paste .github/workflows/ contents and gh run list --limit 10 output. If only partial files are provided, note it: "Audit based on provided files only; some insights may be incomplete." Begin responses from files alone with: "Static-only analysis (not confirmed with live runs)."
Use This Skill When
- The user wants to reduce GitHub Actions runtime, CI cost, or wasted workflow runs.
- The repo has existing workflows in
.github/workflows/or explicit GitHub Actions configuration questions. - The user asks for caching, concurrency, path filters, matrix reduction, job optimization, or workflow-specific fixes.
- The user needs help creating a new GitHub Actions workflow or CI baseline from scratch.
Load Only What You Need
references/actions.md— audits, job gating, matrix reduction, live validation, and workflow-specific fixes.references/reporting.md— when the user asks for a before/after efficiency report.references/patterns.md— full YAML examples when inline audit commands are not enough.
Core Workflow
1. Measure first
rg -n "on:|concurrency:|paths:|paths-ignore:|strategy:|matrix:|cache:" .github/workflows
gh run list --limit 10
run_id=$(gh run list --limit 1 --json databaseId --jq '.[0].databaseId')
gh run view "$run_id" --log-failedLook for: missing dependency caches, missing concurrency cancellation, over-broad triggers, duplicate workflow coverage, and expensive jobs that run on every change regardless of scope.
2. Apply guardrails
Check each proposed fix against these rules before recommending it:
- Does not hide required validation — drop any fix that removes release, schema, migration, or shared-library checks.
- Does not reduce parallelism without justification — drop unless the user prioritised cost over latency and the new critical path stays within 1.25× the original.
- Preserves only documented matrix legs — drop matrix legs with no explicit version or platform commitment.
- Write-back jobs use opt-in triggers — flag (do not drop) formatter or bot jobs that run automatically; recommend an opt-in trigger instead.
- Repo changes stay separate from org settings — split any fix that mixes repo-editable YAML with org-level or GitHub-account settings into two distinct recommendations.
Show full SKILL.md (215 more words)Show less
3. Select the top 3 fixes
From the six candidates below, keep only those supported by audit evidence from step 1 and passing all guardrails from step 2. Rank survivors by estimated daily CI minutes saved (per-run savings × runs per day). Select all candidates that meet both criteria, up to a maximum of 3.
- Add dependency caching with lockfile-based keys
- Add or correct
concurrencycancellation - Remove duplicate workflow coverage before merging jobs
- Narrow workflow or job triggers safely
- Reduce matrix breadth to match risk and event type
- Parallelize independent jobs on the critical path
4. Verify
- If
ghCLI access is available, validate path-gating and concurrency cancellation with a live test push on a non-protected branch. - If live validation is not possible, state that explicitly in the output.
- Treat unexpected live behavior as a real bug even when the YAML looks correct.
Required Output
- Waste sources — top cost or latency drivers found in step 1
- Proposed fixes — top 3 (or all remaining) with supporting audit evidence
- Validation — what was proven live, what was checked locally only, and any remaining risk
- Impact — expected savings vs. measured savings; separate PR wall-clock time from total runner time
