A command that examines a chosen directory and reports on its code structure, design choices, quality problems, and possible improvements. If no directory is given, it examines the current one.

It is for reviewing source folders and getting actionable recommendations based on the project's coding standards.

It provides a repeatable way to find unused code, naming inconsistencies, weak error handling, complexity, and possible security issues.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 253 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00253
Opus 5.5	$0.00000	$0.00101
Sonnet 5.5	$0.00000	$0.00051
Haiku 4.5	$0.00000	$0.00025

Security

Grade A, and why

review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/review

Review the contents of a specified directory and provide a comprehensive analysis of the code structure, patterns, and potential improvements.

Usage

Specify a directory path to review. If no path is provided, reviews the current directory.

Examples:

/review src/ - Review the src directory
/review src/commands/ - Review the commands module
/review - Review the current directory

Steps to execute:

List all files in the specified directory recursively
Analyze the code structure and organization
Identify patterns and architectural decisions
Check for code quality issues:
- Unused code or dependencies
- Inconsistent naming conventions
- Missing error handling
- Potential performance issues
- File size and complexity (consider splitting large files)
- Module organization and separation of concerns
Suggest improvements based on the project's coding standards (CLAUDE.md)
Highlight any security concerns or best practice violations
Provide a summary with actionable recommendations

The review follows the principles outlined in CLAUDE.md:

Memory safety over micro-optimization
Code clarity and maintainability
Clean code maintenance (removing unused elements)
Proper error handling patterns

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

review is a command published in the GitHub repository kopi-vm/kopi (29 stars, last pushed 1y ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 253 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-11-11.
