What it does

Review is an agent skill from microsoft/service-fabric-dotnet, published by the product's own GitHub organization. Review code for correctness, approach, completeness, and consistency with instructions in this repo. Use for initial review, and verifying addressed feedback.

Its SKILL.md is about 980 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 Development, covering Code review. The repository describes itself as: Service Fabric .NET Libraries.

When your agent uses it

  • Verifying addressed feedback
  • Tasks that involve Code review

Example prompts

  • “/review”

Workflow steps

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

  1. Start the reviewer subagent if not explicitly instructed otherwise.
  2. Gather code context.
  3. Perform independent assessment
  4. Perform detailed analysis
  5. Issue a Verdict
  6. Generate a Report

What it can do on your machine

Read from SKILL.md and the folder at commit 4c8ce57. 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

Review loads about 980 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 501 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
~980

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 501 words (~980 tokens).
