review-plan

review-plan is a command for coding agents from FlorianBruniaux/claude-code-plugins. It costs 24 tokens per session (730 once invoked), scanned A, original, MIT.

A structured review of an implementation plan across architecture, dependencies, data flow, scaling, and security before code is written.

In plain words
What is it for?
Use it to inspect a planned system, discuss concrete recommendations, and collect feedback section by section before implementation.
Why use it?
It exposes design risks and trade-offs early, when changing the plan is easier than changing finished code.

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.

Security

Grade A, and why

review-plan 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 3d 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.

Review Plan Before Implementation

Review the current plan thoroughly before making any code changes. For every issue or recommendation, explain the concrete tradeoffs, give an opinionated recommendation, and ask for user input before assuming a direction.

Engineering Preferences

Use these to guide your recommendations (override with project-specific CLAUDE.md preferences if they exist):

  • DRY is important: flag repetition aggressively
  • Well-tested code is non-negotiable: prefer too many tests over too few
  • Code should be "engineered enough": not under-engineered (fragile, hacky) and not over-engineered (premature abstraction, unnecessary complexity)
  • Err on the side of handling more edge cases, not fewer
  • Bias toward explicit over clever; thoughtfulness over speed

Review Pipeline

Work through each section sequentially. After each section, pause and ask for feedback before moving on.

1. Architecture Review

Evaluate:

  • Overall system design and component boundaries
  • Dependency graph and coupling concerns
  • Data flow patterns and potential bottlenecks
  • Scaling characteristics and single points of failure
  • Security architecture (auth, data access, API boundaries)

2. Code Quality Review

Evaluate:

  • Code organization and module structure
  • DRY violations (be aggressive here)
  • Error handling patterns and missing edge cases (call these out explicitly)
  • Technical debt hotspots
  • Areas that are over-engineered or under-engineered relative to engineering preferences

3. Test Review

Evaluate:

  • Test coverage gaps (unit, integration, e2e)
  • Test quality and assertion strength
  • Missing edge case coverage (be thorough)
  • Untested failure modes and error paths

4. Performance Review

Evaluate:

  • N+1 queries and database access patterns
  • Memory-usage concerns
  • Caching opportunities
  • Slow or high-complexity code paths

Issue Reporting Format

For every specific issue found (bug, smell, design concern, or risk):

  1. Describe the problem concretely, with file and line references
  2. Present 2-3 options, including "do nothing" where that's reasonable
  3. For each option, specify: implementation effort, risk, impact on other code, and maintenance burden
  4. Give your recommended option and why, mapped to engineering preferences above
  5. Ask explicitly whether the user agrees or wants to choose a different direction before proceeding

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-plan is a command published in the GitHub repository FlorianBruniaux/claude-code-plugins (40 stars, last pushed 3mo ago), licensed MIT. It adds 24 tokens to every session and 730 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-30.
