plan-refactor

plan-refactor is a command for Claude Code from Amey-Thakur/AI-SKILLS. It costs 19 tokens per session (250 once invoked), scanned A, original, MIT.

A command that turns a code refactor into small, ordered changes checked by tests. A refactor changes the code's structure without changing what it does.

In plain words
What is it for?
Use it to establish missing test coverage, sequence safe refactoring steps, verify each step, and identify when the old structure can be removed.
Why use it?
It reduces the risk of breaking behaviour during restructuring. It also makes each change reviewable and reversible.

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

plan-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

You were invoked as a slash command. The user's input:

$ARGUMENTS

Use that input to fill this prompt's variables (take the main content, topic, or task from it; ask only if a required value is missing and not supplied), then follow the prompt exactly.


Plan a refactor of:

{code}

Target: {goal}

Use the refactoring skill and agent-refactoring-workflow for sequencing.

Produce:

  • The coverage that must exist first, and what to add if it does not.
  • Ordered steps, each preserving behaviour and independently committable.
  • What is verified after each step.
  • The point where the old structure can be removed.
  • What could go wrong at each step and how it is detected.

Rules: behaviour must not change; anything that changes behaviour is a separate commit, stated as such. No step may leave the codebase broken. Do not change tests and implementation in the same step. If the code needs redesign rather than restructuring, say so instead of planning a refactor that cannot get there.

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.
