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 | $0.00042 | $0.01499 |
| Opus 5 | $0.00021 | $0.00749 |
| Sonnet 5 | $0.00008 | $0.00300 |
| Haiku 4.5 | $0.00004 | $0.00150 |
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 yesterday.
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 — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Intent (anchor): Change code structure safely while preserving observable behavior. Always: establish a passing baseline; make one atomic refactoring step at a time; build and test after every step. Never: combine refactoring with behavior changes or continue from a broken baseline.
Shared policy: Follow
instructions/coordination.instructions.mdfor precedence, invocation, delegation, and handoffs. Applyinstructions/workflow.instructions.mdfor proportional work and verification.
You are executing a disciplined refactoring process with safety guarantees.
Your goals are to:
- Preserve behavior — refactoring changes structure, not behavior.
- Verify continuously — tests must pass after every atomic step.
- Work incrementally — small, reversible changes, not big-bang rewrites.
- Prepare clean commit-review handoff — when refactoring is verified, recommend
git-commit-reviewrather than owning commit strategy.
When to use this skill
Use this skill whenever:
- Restructuring code without changing its behavior (rename, extract, move, inline, etc.).
- The user asks to "refactor", "clean up", "reorganize", or "restructure" code.
- Preparatory refactoring before a feature (making the codebase ready for a change).
- Reducing technical debt in a specific area.
Do not use this skill for:
- Adding new features or behavior — that's implementation, not refactoring.
- Bug fixes that change behavior — fix the bug directly.
- Trivial renames with no structural impact — just do them (Trivial tier).
Workflow
Phase 1: Establish Baseline
Before touching anything:
- Run the full test suite — record pass/fail counts. This is your safety net.
- If tests are failing — HARD STOP. Do not refactor against a broken baseline. Report the failures and do not proceed until the baseline is fixed outside this refactoring.
- Identify the refactoring scope — which files, classes, or modules are affected?
- Check for coverage — are the areas you're refactoring covered by tests? If not, flag this as a risk.
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 NickPolyder/NP.CoPilot.Config (2 stars, last pushed 7d ago), licensed MIT. It adds 42 tokens to every session and 1,499 once invoked, about $0.0002 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.
