simplify

simplify is a command for Claude Code from felvieira/claude-skills-fv. It costs 17 tokens per session (396 once invoked), scanned A, original, Apache-2.0.

A command for simplifying and refactoring code while keeping its behavior unchanged. Refactoring means restructuring code without changing what it does.

In plain words
What is it for?
Use it to clean up code, or to produce a review list of safely removable dead code, unused imports, unused variables, uncalled functions, and unreachable branches.
Why use it?
It helps reduce complexity, remove duplication, and improve readability while using tests to check that behavior stays the same.

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

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 11d 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

/simplify — Simplificação e Refatoração

Objetivo: Reduzir complexidade, eliminar duplicação, melhorar legibilidade sem mudar comportamento.

Skill ativada: 23 — Migration & Refactor Specialist

Input esperado: Arquivo(s) ou módulo(s) alvo, motivo da simplificação.

Output esperado: Código refatorado, mais limpo e DRY, com testes garantindo que comportamento não mudou.

Policies relevantes:

  • policies/search-first.md — entender dependências antes de refatorar
  • policies/anti-rationalization.md — não simplificar demais nem de menos

Uso: /simplify [arquivo ou módulo a simplificar]

Modo delete-list

/simplify --delete-list [arquivo ou módulo] — em vez de aplicar a refatoração direto, gera uma lista de candidatos a remoção, sem tocar no arquivo:

O que remover Onde (arquivo:linha) Por quê é seguro remover
... ... ...

Cobre 5 categorias: código morto, imports não usados, variáveis não referenciadas, funções não chamadas, branches inalcançáveis. Ver skills/23-migration-refactor-specialist/SKILL.md (seção "Delete-List Review") para o critério de segurança e o carve-out de código de segurança/validação/a11y.

Uso padrão (sem a flag) continua editando direto, sem mudança.

Fontes: modo delete-list adaptado do conceito de "delete-list review" do projeto DietrichGebert/ponytail (MIT) — só o conceito, nenhum código copiado.

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.
