What it does

Review Changes is an agent skill from timothywarner-org/claude-code. Review uncommitted local changes in the current git working tree for bugs, smells, missing tests, and CLAUDE.md voice violations. Use when the user asks to "review my changes", "look at my diff", "check my staged changes", "code review my working tree", or wants a sanity check before committing or opening a PR. Do NOT use for already-open pull requests on GitHub (that's the separate review command).

Its SKILL.md is about 510 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 Pull requests and Agent instruction files. It works with Git and GitHub. The repository describes itself as: Claude Code and Large-Context Reasoning (O'Reilly Live Learning). The licence is MIT.

When your agent uses it

  • The user asks to review my changes
  • Look at my diff
  • Check my staged changes
  • Code review my working tree

Example prompts

  • “review my changes”
  • “look at my diff”
  • “check my staged changes”
  • “/review-changes”

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash(git:*)

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. No em dashes. Hyphens with spaces, commas, or periods only.
  2. Never use "ask" as a noun. "A heavy ask" is a rewrite.
  3. No AWS references. Not in code, not in comments, not in docs.
  4. No hardcoded secrets. Flag any string that looks like an API key, token, or password.
  5. No console.log in shipped JS/TS. Test files and demos in segment_*/ are fine.

What it can do on your machine

Read from SKILL.md and the folder at commit cb80eae. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Bash(git:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Review Changes loads about 506 tokens when it runs. Until then it costs about 105 tokens; SKILL.md has 195 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~105
When it runs · the whole SKILL.md, loaded when a task matches
~506

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.

Your task

Review the changes above. Flag bugs, anti-patterns, missing tests, and any violation of this repo's voice rules. Be terse, be honest, no glazing.

Hard checks (block-on-find)
  1. No em dashes. Hyphens with spaces, commas, or periods only.
  2. Never use "ask" as a noun. "A heavy ask" is a rewrite.
  3. No AWS references. Not in code, not in comments, not in docs.
  4. No hardcoded secrets. Flag any string that looks like an API key, token, or password.
  5. No console.log in shipped JS/TS. Test files and demos in segment_*/ are fine.
Soft checks (note, don't block)
  1. Comments explain WHY, not WHAT. Code shows what; comments justify design.
  2. PowerShell-first for shell scripts. Bash is the fallback.
  3. Azure-first for cloud examples. Never compare to other clouds.
  4. Docstrings/JSDoc on every new function or PowerShell script.
  5. Idempotent re-runs where state mutation is involved.
Report format
## Blockers
- file:line - issue - proposed fix

## Soft findings
- file:line - note

## What's working
- one or two things the diff got right (keep it brief, no glazing)

If the diff is empty, say so and stop. Do not invent findings.
