A refactoring workflow for changing code structure while keeping its behavior the same. Refactoring means reorganizing code without intentionally changing what it does.

Use it to prepare tests, reorganize an implementation, enforce a no-test-edit rule, and verify the project's checks before and after the change.

It uses existing checks and, where needed, characterization tests to detect accidental behavior changes before the work proceeds.

Per session 26 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.00143
Opus 5.5	$0.00010	$0.00057
Sonnet 5.5	$0.00005	$0.00029
Haiku 4.5	$0.00003	$0.00014

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 9d 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 what is described after the skill name. ./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. The mini-spec gets the self-critique pass of prompts/spec.md; set Self-critique: done after my approval. Stop at every human gate, one decision per gate message (workflows/segments.md, Contract, Gate).

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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 skill published in the GitHub repository engindemirog/ai-native-engineering-workspace (114 stars, last pushed 4d ago), licensed MIT. It adds 26 tokens to every session and 143 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-20.
