refactorer

A code-cleanup agent for removing unused code, combining duplicate code, and simplifying structure without changing behavior.

In plain words
What is it for?
Use it when a project contains dead code, repeated functions, or unnecessary abstractions that need a deeper refactoring review.
Why use it?
It helps reduce clutter and complexity while checking that the cleanup has not broken tests.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 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

Agent: codi-refactorer

Code cleanup agent for removing dead code, consolidating duplicates, and simplifying without changing behavior.

When to Delegate

  • Detected dead code needs safe removal with test verification
  • Duplicate functions or redundant abstractions need consolidation
  • The user asks for deeper refactoring analysis

How to Use

Defined at .codi/agents/codi-refactorer.md. Invoke via the Agent tool with subagent_type set to codi-refactorer.

Key Capabilities

  • Dead code detection across multiple languages
  • Safe deletion with test verification after each change
  • Duplicate consolidation and complexity reduction
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.

refactorer is an agent published in the GitHub repository lehidalgo/codi (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 134 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 2026-08-31.
