What it does
Skill Reviewer is an agent skill from microsoft/GitHub-Copilot-for-Azure, published by the product's own GitHub organization. Review skill PRs with structured severity-rated feedback covering token budgets, routing conflicts, and repo conventions. WHEN: "review skill", "review skill PR", "review skill changes", "check skill quality", "skill PR feedback".
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/output-format.md`, `references/review-checklist.md` and `references/routing-analysis.md`).
It sits in Development, covering Pull requests and LLM cost and token optimization. The repository describes itself as: GitHub Copilot for Azure. The licence is MIT.
When your agent uses it
- Tasks that involve Pull requests
- Tasks that involve LLM cost and token optimization
Example prompts
- “review skill”
- “review skill PR”
- “review skill changes”
- “/skill-reviewer”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Collect — Identify all changed skill files (SKILL.md, references, tests, scripts)
- Check — Run each category from the review checklist
- Classify — Assign severity per the severity guide
- Analyze Routing — Check triggers for conflicts per routing analysis
- Draft — Write the review per the output format
- Validate — Verify suggested fixes are actionable with accurate file/line references
What it can do on your machine
Read from SKILL.md and the folder at commit fcf2f3b. 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
Skill Reviewer loads about 482 tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 162 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.
