Getting it into your agent
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.

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 | $0.00102 | $0.02536 |
| Opus 5 | $0.00051 | $0.01268 |
| Sonnet 5 | $0.00020 | $0.00507 |
| Haiku 4.5 | $0.00010 | $0.00254 |
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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Refactor
Refactor code safely using characterization tests, incremental changes, and continuous verification. Every change preserves existing behavior while improving code structure, readability, and maintainability.
Refactoring Goal
$ARGUMENTS
Core Principle: Behavior Preservation
Refactoring changes code structure WITHOUT changing behavior. Every step must be verified against existing tests. If tests break, the refactoring introduced a bug: revert and retry.
Anti-Hallucination Guidelines
- Read before changing: understand all callers and dependencies first.
- Test before and after: full suite before starting, and again after every incremental change. Results must match.
- Characterization tests first: where coverage is thin, capture current behavior in tests before restructuring.
- Incremental changes: one small, verifiable change at a time. Never combine steps into a single edit.
- No feature changes: refactoring doesn't add features, fix bugs, or change behavior; those are separate tasks (
implement-feature,fix-bug). Phase 0's scope gate below is where this gets enforced, not just stated. - Reference real code: never claim a structure you haven't verified by reading the actual files.
- Prefer deletion over addition: when several call sites share logic, consolidate it into one place and delete the copies, rather than wrapping them in a new abstraction.
- Never trim the floor: simplifying structure must not drop a validation check, an error/data-loss path, a security control, or an accessibility branch. If a step would drop one, it's a behavior change, not a refactor, stop and re-scope it separately.
Quality Gates
A Stop hook re-runs the Phase 4 Quality Gates Checklist automatically and blocks completion if any item fails, see the hook prompt above for the exact wording.
Task Management
Whether the ceremony below (formal task chain, subagent fan-out) is worth it depends on blast radius, not on whether the skill fired.
What ships with it
4 files 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.
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 mgiovani/cc-arsenal (7 stars, last pushed 4d ago), licensed MIT. It adds 102 tokens to every session and 2,536 once invoked, about $0.0005 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.
