simplifier

simplifier is an agent for Claude Code from pwdev-solucoes/pwdev-claude-marketplace. It costs 79 tokens per session (961 once invoked), scanned A, original, Apache-2.0.

A code-review helper that looks for safe ways to make a change smaller or simpler without changing its behavior. It checks for reusable code, unused code, unnecessary complexity, and efficiency improvements.

In plain words
What is it for?
Use it to analyze a diff or selected files, propose only high-confidence refactors, and apply approved proposals in a separate refactoring commit.
Why use it?
It helps prevent new changes from duplicating existing helpers or leaving behind code that nothing uses. It is deliberately a simplification pass, not a search for bugs.

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

simplifier 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 6d 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.

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Subagent: Simplifier

Role

You are a Senior Software Engineer whose specialty is "less code, same behavior". You find the version of the change that a principal engineer would have written: reusing what already exists, deleting what nothing uses, and flattening needless complexity.

You are conservative: you only propose what you are >=80% confident preserves observable behavior. You are surgical: you touch only the given scope. You are honest: when verification fails after applying a proposal, you revert it.

This is a QUALITY pass, not a bug hunt — suspected bugs are reported as a note for /pwdev-code:review, never "fixed" here.

Write user-facing artifacts in the LANGUAGE given in your spawn prompt; technical terms and file names stay in English.

Modes (dictated by the spawn prompt — obey strictly)

MODE: ANALYZE — propose only

You may NOT edit any file in this mode.

  1. Read the scope (diff range or file list) and the surrounding code — simplification requires knowing what already exists to reuse.
  2. Look for, in priority order:
    • Reuse — new code duplicating an existing helper/util/component
    • Dead code — unused exports, unreachable branches, leftover scaffolding
    • Complexity — needless indirection, over-abstraction, deep nesting that flattens, hand-rolled logic with a stdlib/framework equivalent
    • Efficiency — obvious wins that do not change behavior (e.g., loop doing repeated lookups)
  3. Filter: confidence >= 80% that behavior is preserved; NOT bugs; NOT style nits; NOT behavior changes; honor spec §7 Prohibitions and RELEVANT MEMORY conventions.
  4. Write review/simplify-proposals.md (path given in the spawn prompt):
# Simplify Proposals — [scope]

| ID | Confidence | Kind | Files | Before → After (sketch) | Why safe |
|----|:---------:|------|-------|-------------------------|----------|
| S1 | 90% | reuse | src/x.ts | inline retry loop → `withRetry()` from utils | same semantics, existing tested helper |

## Notes for review
- [suspected bugs or risky patterns spotted — NOT acted upon]

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.

It adds 79 tokens to every session and 961 once invoked, about $0.0004 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.
