What it does

Piv Review Changes is an agent skill from coleam00/skills. Performs a technical code review of recently changed files for bugs, security issues, and standards compliance, then writes a report. Use before committing, as a pre-commit quality gate.

Its SKILL.md is about 700 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 and Quality gates. The repository describes itself as: The agent skills I actually use to build software with coding agents. The PIV loop, planning, worktrees, and the meta-skills for building your own AI Layer. The licence is MIT.

When your agent uses it

  • Tasks that involve Code review
  • Tasks that involve Quality gates

Example prompts

  • “Use the piv-review-changes skill to perform a technical code review of recently changed files for bugs, security issues, and standards compliance…”
  • “/piv-review-changes”

Workflow steps

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

  1. Logic Errors
  2. Security Issues
  3. Performance Problems
  4. Code Quality
  5. Adherence to Codebase Standards and Existing Patterns

What it can do on your machine

Read from SKILL.md and the folder at commit 847be08. 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:

    • 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

Piv Review Changes loads about 699 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 302 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~699

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.

Code Review

Perform technical code review on recently changed files.

Core Principles

Review Philosophy:

  • Simplicity is the ultimate sophistication - every line should justify its existence
  • Code is read far more often than it's written - optimize for readability
  • The best code is often the code you don't write
  • Elegance emerges from clarity of intent and economy of expression

What to Review

Start by gathering codebase context to understand the codebase standards and patterns.

Start by examining:

  • CLAUDE.md
  • README.md
  • Key files in the core module
  • Documented standards in the docs directory (and any .claude/references/ docs)

After you have a good understanding, run these commands:

bash
git status
git diff HEAD
git diff --stat HEAD

Then check the list of new files:

bash
git ls-files --others --exclude-standard

Read each new file in its entirety. Read each changed file in its entirety (not just the diff) to understand full context.

For each changed file or new file, analyze for:

  1. Logic Errors

    • Off-by-one errors
    • Incorrect conditionals
    • Missing error handling
    • Race conditions

  2. Security Issues

    • SQL injection vulnerabilities
    • XSS vulnerabilities
    • Insecure data handling
    • Exposed secrets or API keys

  3. Performance Problems

    • N+1 queries
    • Inefficient algorithms
    • Memory leaks
    • Unnecessary computations

  4. Code Quality

    • Violations of DRY principle
    • Overly complex functions
    • Poor naming
    • Missing type hints/annotations

  5. Adherence to Codebase Standards and Existing Patterns

    • Adherence to standards documented in the docs directory
    • Linting, typing, and formatting standards
    • Logging standards
    • Testing standards

Verify Issues Are Real

  • Run specific tests for issues found
  • Confirm type errors are legitimate
  • Validate security concerns with context

Output Format

Save a new file to .claude/code-reviews/[appropriate-name].md

Stats:

  • Files Modified: 0
  • Files Added: 0
  • Files Deleted: 0
  • New lines: 0
  • Deleted lines: 0

For each issue found:

severity: critical|high|medium|low
file: path/to/file.py
line: 42
issue: [one-line description]
detail: [explanation of why this is a problem]
suggestion: [how to fix it]

If no issues found: "Code review passed. No technical issues detected."

Important

  • Be specific (line numbers, not vague complaints)
  • Focus on real bugs, not style
  • Suggest fixes, don't just complain
  • Flag security issues as CRITICAL
