code-polish

code-polish is a skill for Claude Code, Codex from PaulRBerg/agent-skills. It costs 36 tokens per session (1,162 once invoked), scanned A, original, MIT.

A guide for simplifying changed code and reviewing it for defects within a fixed set of files. It focuses on high-confidence changes while preserving the code's behavior and public interfaces.

In plain words
What is it for?
Use it after code changes when asked to simplify, review, or do both. It is intended for files in a Git repository and excludes generated files, lockfiles, vendored code, and minified bundles unless requested.
Why use it?
It helps reduce unnecessary complexity and catch evidenced problems without expanding the review beyond the agreed scope. It also accounts for risk, exclusions, and verification.

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

code-polish 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 5d 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.

Code Polish

Resolve scope once, make only high-confidence simplifications, fix evidenced defects by risk, and verify the final state.

Modes

  • --simplify: simplify only.
  • --review: review and fix only.
  • Neither or both: simplify, then review the simplified result.
  • --with-profile <name> / --skip-profile <name>: add or suppress review profiles; skip wins.

Fixed Scope

  1. Require a Git repository.
  2. Use explicit paths, patterns, ranges, natural-language targets, or a supplied resolved-scope block when present. Otherwise use only files modified in this session; if session history is unavailable, use all uncommitted tracked and untracked files.
  3. Exclude lockfiles, generated outputs, vendored code, minified bundles, and large data snapshots from manual review unless explicitly requested. Validate relevant excluded outputs through their generator, schema, or invariants.
  4. Resolve and retain one authoritative scope set and optional exclusions for execution. Do not broaden or recompute scope later. Stop if it is empty.

Simplify

Preserve public contracts, inputs, outputs, side effects, error behavior, performance-sensitive characteristics, telemetry, and operational guards. Apply only changes with a concrete comprehension or defect-risk benefit:

  • flatten avoidable control-flow nesting;
  • clarify misleading names or dense transforms;
  • remove real duplication when the abstraction reduces total complexity;
  • tighten local types and contracts without broad churn;
  • remove only dead code caused by this session's edits.

Do not split by line count, perform architecture cleanup, convert sync/async APIs, add speculative configurability, or replace readable duplication with a one-use abstraction. A no-op is a valid result.

Review and Fix

Judge the diff against the user's request. Prioritize CRITICAL → HIGH → MEDIUM → LOW:

  • CRITICAL: exploitable security, data loss, or critical outage path.
  • HIGH: behavior, error-path, boundary, or performance defect affecting core behavior.
  • MEDIUM: resource leak, complexity hotspot, test gap, over-scoped change, speculative complexity, or weak success criterion likely to cause defects.
  • LOW: localized clarity or style issue with a real maintenance cost.

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.

code-polish is a skill published in the GitHub repository PaulRBerg/agent-skills (70 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 1,162 once invoked, about $0.0002 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.
