flow.review

A structured workflow for reviewing a codebase across several review categories and recording findings with effort, impact, and severity ratings.

In plain words
What is it for?
Use it to inspect an existing Git project, review selected or all categories, preview findings, or automatically process low-effort fixes.
Why use it?
It makes broad code reviews more systematic and turns approved findings into planned implementation work instead of leaving them as informal notes.

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

flow.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.

User Input

$ARGUMENTS

Arguments:

  • Empty: Run full interactive review with category-by-category approval
  • --dry-run: Generate findings without creating phase (preview mode)
  • --categories <list>: Review only specified categories (comma-separated: BP,RF,HD,MF,OC,OE,OD,SC,UI)
  • --fix: Auto-approve findings with effort ≤4, defer effort=5 items, then auto-run /flow.orchestrate

You MUST consider the user input before proceeding (if not empty).

Note: Use specflow directly, NOT npx specflow. It's a local CLI at ~/.claude/specflow-system/bin/.

Prerequisites

Requirement Check Command If Missing
ROADMAP.md exists cat ROADMAP.md Run /flow.roadmap
Constitution .specify/memory/constitution.md Run /flow.init
Codebase to review ls -la Need code to review
Git repo git status Initialize git repo

Goal

Perform a systematic code review across 7 categories, generate findings with effort/impact/severity ratings, allow interactive user approval, create an implementation phase for approved items, and defer rejected items to the backlog.

This is a refinement workflow focused on:

  • Implementing coding best practices
  • Identifying refactoring opportunities
  • Recommending hardening improvements
  • Finding missing/incomplete features
  • Cleaning up orphaned code
  • Simplifying over-engineered solutions
  • Updating outdated documentation

Constraints:

  • Does NOT propose brand new features
  • Does NOT break existing functionality without confirmation
  • Focus on technical debt reduction and code quality

Review Categories

Code Category Focus
BP Best Practices Coding standards violations, anti-patterns, inconsistencies
RF Refactoring Code duplication, complex functions (>100 lines), poor structure
HD Hardening Error handling gaps, input validation, security patterns
MF Missing Features TODOs, FIXMEs, stub functions, incomplete implementations
OC Orphaned Code Unused exports, dead code, unreferenced files
OE Over-Engineering Excessive abstraction, unused flexibility, premature optimization
OD Outdated Docs Stale comments, README mismatches, incorrect examples
SC Spec Compliance Implementation doesn't match spec.md requirements (if phase artifacts exist)
UI UI Compliance UI doesn't match ui-design.md mockups (if ui-design.md exists)

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.

flow.review is a skill published in the GitHub repository billbuchanan-code/claude-code-power-setup (2 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 4,659 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 2026-08-31.
