refactor

refactor is a command for Claude Code from hamr0/liteagents. It costs 7 tokens per session (3,056 once invoked), scanned A, original, Apache-2.0.

A command for simplifying code without changing what it does. It focuses on reducing complexity, improving names and readability, removing repetition, and making functions smaller.

In plain words
What is it for?
Use it for safe refactoring of an existing project. It detects the project’s test command, runs the relevant tests, and stops for a decision if the refactor causes failures.
Why use it?
It helps make code easier to understand and maintain while preserving the public interface. It requires existing tests to pass so accidental behavior changes are detected.

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

refactor 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 15d 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.

Refactor $ARGUMENTS. A targeted refactor includes the performance pass below — it is on by default, not a separate command.

Guardrails

  • Spawn a worker, mid tier stated explicitly (omitted inherits the parent's, not the balanced one; not cheapest/fastest either — judgment degrades there; never a vendor model name). Fall back to running inline if your tool has no subagent mechanism.
  • Escalate, never assume. Anything you cannot decide, cannot verify, or that this spec does not cover → stop and report it to the orchestrator (the main session). Never improvise, never widen scope, never fix a side issue you noticed along the way.
  • The worker does the work itself — no delegation. The fixer must not spawn subagents of its own. Every edit it reports, and every test run it cites, has to be one it made or ran with its own tool calls: a relayed "I fixed it and the suite is green" from a sub-worker is hearsay, and this command's whole output is the claim that a change landed and the tests still pass. A fix that delegates its work is a report about a report.
  • The HITL gates below belong to the orchestrator, not the worker. A subagent cannot hold a conversation with the user, so it cannot run a gate that ends in stop and ask. When one trips — a failing test, a crossed public API boundary, a change bigger than the bullet asked for — the worker stops there and hands the situation back, with the options and its reasoning but no choice made. The orchestrator asks. A worker that picks revert / patch / update-test on the user's behalf has answered a question it was never allowed to ask.
  • Edit only what a surviving bullet names. Ledger mode's scope is the bullets that survive revalidation, one change per bullet — not the neighbouring code, not the formatting, not a second finding noticed on the way past. Anything else goes back to the orchestrator to become a new bullet.
  • Prove the blast radius with two checks, because neither sees what the other does. git status --porcelain at exit must list only files a surviving bullet named — that is this command's scope guarantee, and unlike /branch-review it is not expected to be empty. It cannot police the memory directory: .factory/ is normally gitignored, so porcelain stays empty whether you deleted a fixed bullet, wrote nothing, or overwrote MEMORY.md. So also hash the files there before you start and again before you report:
    find .factory/remember -maxdepth 1 -type f -exec md5sum {} + | sort -k2
    
    and show the comparison: only fix-ledger.md may differ. last-review.md in particular is /branch-review's to write — a fixer that touches it forges the gate that judges its own work.

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.
