excel-mcp: Command for Claude Code

.claude/commands/code-quality/refactor-simple.md

refactor-simple is a command for Claude Code from mort-lab/excel-mcp. It costs 0 tokens per session (187 once invoked), scanned A, a copy of refactor-simple, MIT.

A command that reviews Python code for small, actionable design and typing problems.

In plain words
What is it for?
Use it to check Python changes involving Pydantic v2, vertical-slice structure, function size, class responsibilities, and type hints.
Why use it?
It helps find overly complex functions, missing type information, weak data validation, and code that crosses feature boundaries.

Command for Claude Code

Written for Claude Code: installed under .claude/.

This is mort-lab/excel-mcp's own configuration. It tells Claude Code how to work on excel-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything excel-mcp configures →

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-simple 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 2mo 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.

Origin

This is a copy

100% identical to refactor-simple — 61 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Quick refactoring check for Python code focusing on:

  • Vertical slice boundaries
  • Function complexity
  • Type safety with Pydantic v2
  • Single responsibility

Scan for:

  1. Functions >20 lines that need decomposition
  2. long files that need decomposition
  3. Missing Pydantic models for I/O
  4. Cross-feature imports violating vertical slices
  5. Classes with multiple responsibilities
  6. Missing type hints

Desired architecture:

  • Vertical slice boundaries
  • Single responsibility
  • Type safety with Pydantic v2

For each issue found, provide:

  • Location
  • Why it's a problem
  • Specific fix with code example
  • Specific place where the fix should be implemented
  • Priority (high/medium/low)

Focus on actionable items that can be fixed in <1 hour each.

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-simple is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 187 tokens. A static security scan graded it A with 0 findings. It is 100% identical to refactor-simple, differing in 61 lines, and is treated as a copy.
