cmd-code-simplify

A code-cleanup workflow that makes recently changed code easier to read and maintain without changing what it does.

In plain words
What is it for?
Use it to simplify functions, reduce deep nesting, extract shared logic, improve names, and verify the result with tests and a build.
Why use it?
It reduces confusing structure, duplication, dead code, and unclear names while checking that behavior stays the same.

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.

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

cmd-code-simplify 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

Invoke the agent-skills:code-simplification skill.

Simplify recently changed code (or the specified scope) while preserving exact behavior:

  1. Read CLAUDE.md and study project conventions
  2. Identify the target code — recent changes unless a broader scope is specified
  3. Understand the code's purpose, callers, edge cases, and test coverage before touching it
  4. Scan for simplification opportunities:
    • Deep nesting → guard clauses or extracted helpers
    • Long functions → split by responsibility
    • Nested ternaries → if/else or switch
    • Generic names → descriptive names
    • Duplicated logic → shared functions
    • Dead code → remove after confirming
  5. Apply each simplification incrementally — run tests after each change
  6. Verify all tests pass, the build succeeds, and the diff is clean

If tests fail after a simplification, revert that change and reconsider. Use code-review-and-quality to review the result.

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.

cmd-code-simplify is a cursor rule published in the GitHub repository nota-america/forgecat-agent-profiles (58 stars, last pushed 4d ago), licensed Apache-2.0. It adds 227 tokens to every session, about $0.0011 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 2026-08-30.
