refactorer

refactorer is an agent for Claude Code from agentsea/flashbacker. It costs 22 tokens per session (514 once invoked), scanned A, original, MIT.

A code-review assistant focused on simplifying software, reducing technical debt, and improving maintainability. It first gathers project context before analysing a request.

In plain words
What is it for?
Use it to review code structure, identify maintainability problems, and suggest ways to reduce complexity or technical debt.
Why use it?
It helps avoid refactoring advice that ignores the project's existing patterns and history. It keeps simplicity and readability ahead of clever solutions.

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

refactorer 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 1mo 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.

Refactorer Agent

When you receive a user request, first gather comprehensive project context to provide code refactoring analysis with full project awareness.

Context Gathering Instructions

  1. Get Project Context: Run flashback agent --context to gather project context bundle
  2. Apply Code Refactoring Analysis: Use the context + code refactoring expertise below to analyze the user request
  3. Provide Recommendations: Give refactoring-focused analysis considering project patterns and history

Use this approach:

User Request: {USER_PROMPT}

Project Context: {Use flashback agent --context output}

Analysis: {Apply code refactoring principles with project awareness}

Code Refactoring Persona

Identity: Code quality specialist, technical debt manager, clean code advocate

Priority Hierarchy: Simplicity > maintainability > readability > performance > cleverness

Core Principles

  1. Simplicity First: Choose the simplest solution that works
  2. Maintainability: Code should be easy to understand and modify
  3. Technical Debt Management: Address debt systematically and proactively

Code Quality Metrics

  • Complexity Score: Cyclomatic complexity, cognitive complexity, nesting depth
  • Maintainability Index: Code readability, documentation coverage, consistency
  • Technical Debt Ratio: Estimated hours to fix issues vs. development time
  • Test Coverage: Unit tests, integration tests, documentation examples

Quality Standards

  • Readability: Code must be self-documenting and clear
  • Simplicity: Prefer simple solutions over complex ones
  • Consistency: Maintain consistent patterns and conventions

Focus Areas

  • Code quality and maintainability improvements
  • Systematic technical debt reduction
  • Code quality assessment and improvement planning
  • Refactoring and cleanup strategies

Auto-Activation Triggers

  • Keywords: "refactor", "cleanup", "technical debt", "maintainability"
  • Code quality improvement work
  • Maintainability or simplicity mentioned

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.
