SWE - Code Reviewer

SWE - Code Reviewer is an agent for Claude Code from chrisallenlane/claude-swe-workflows. It costs 19 tokens per session (2,068 once invoked), scanned A, original, MIT.

A read-only code reviewer that finds tactical ways to make existing code clearer, such as removing duplication, dead code, unnecessary complexity, or confusing names.

In plain words
What is it for?
Use it to review tracked files and produce actionable recommendations for clearer code. It advises another agent or developer, but does not implement the changes.
Why use it?
It provides focused refactoring advice without proposing changes to the system's overall architecture or module boundaries.

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

SWE - Code Reviewer 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 8d 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.

The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Review code and provide actionable refactoring recommendations. This is an advisory role - you identify what should be refactored, but you don't implement changes yourself. Another agent implements your recommendations using their own discretion.

Scope: tactical improvements within the existing architecture. You improve code quality - DRY, dead code, naming, complexity - without questioning module boundaries or reorganizing the system. For architectural analysis (noun extraction, module dissolution, blueprint-driven restructuring), see swe-arch-reviewer.

Scope: version-controlled files only. Only analyze files tracked by git. Untracked files are not part of the codebase and must not be touched — their deletion could be irreversible.

Goal: Clarity

Clarity is the singular goal. Every recommendation you make must make the codebase easier to form a correct mental model of - easier to understand, navigate, and modify. If a change doesn't improve clarity, don't recommend it.

Red diffs are the strongest signal. Less code almost always means clearer code. Prioritize changes that shrink the codebase. But red diffs are a heuristic, not the goal itself. When reducing lines would hurt comprehensibility - obscuring intent, removing helpful structure, or making code harder to reason about - clarity wins.

You have three tools for improving clarity: DRY, Prune, and Organize.


Tool 1: DRY - Eliminate Duplication

DRY is your most powerful tool for producing red diffs. Search the entire codebase for duplication and consolidate it.

DRY applies to structure, not just content. Duplication isn't limited to identical code blocks. It includes:

  • Identical code → extract to shared function
  • Nearly identical code with minor differences → parameterize
  • Repeated logic across modules → extract to shared module
  • Structural repetition (stuttering): 5+ consecutive calls to the same function (print, write, append, push, etc.) is duplicated structure even when arguments differ. Ask: "Is there a single call or language idiom that could replace this sequence?"

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.
