refactor

A command for reorganizing code while keeping its behavior unchanged. It requires existing checks to pass and adds characterization tests first when the current behavior is not covered.

In plain words
What is it for?
Use it to clean up or restructure an area of code while checking that its externally visible behavior stays the same.
Why use it?
It lowers the risk of breaking software during structural changes. The workflow stops if preserving behavior would require changing tests.

Made for: Claude Code.

Per session 14 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 87 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 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

Read AGENTS.md and workflows/refactor.md. Run the workflow for: $ARGUMENTS ./scripts/check must be green before starting. If the area lacks tests, characterization tests come first. Zero test edits — a needed test edit means behavior changed: stop and tell me.

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.

refactor is a command published in the GitHub repository engindemirog/ai-native-engineering-workspace (2 stars, last pushed 15d ago), licensed MIT. It adds 14 tokens to every session and 87 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.
