outline-mcp-rs: Skill for Claude Code

.claude/skills/refactor/SKILL.md

refactor is a skill for Claude Code from nizovtsevnv/outline-mcp-rs. It costs 11 tokens per session (1,193 once invoked), scanned A, original, MIT.

A code-quality workflow for finding design problems and safely reorganising an existing Rust project without changing its intended behaviour.

In plain words
What is it for?
It measures warnings and file sizes, runs tests, and reviews architecture, responsibilities, dependencies, and other design concerns.
Why use it?
It checks whether the project builds and its tests pass before suggesting structural improvements, so refactoring does not start from a broken baseline.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions CLAUDE.md; names the AskUserQuestion tool.

This is nizovtsevnv/outline-mcp-rs's own configuration. It tells Claude Code how to work on outline-mcp-rs 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 outline-mcp-rs 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 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.

Refactor

Code quality analysis and incremental refactoring with continuous validation.

Arguments (optional):

  • Path or crate: /refactor crates/app — limit scope
  • No arguments — analyze the entire project

Process

Phase 1: Exploration

  1. Read CLAUDE.md and doc/ru/PRD.md for project rules and conventions
  2. Collect baseline metrics (in parallel):
    • cargo clippy --workspace --all-targets 2>&1 — warnings count
    • Glob + wc — LOC per crate, files >400 lines
    • cargo test --workspace 2>&1 — baseline: all tests passing?
  3. If tests fail or code doesn't compile — report and stop

Phase 2: Diagnosis

Analyze code across 8 dimensions. For large scope, use parallel Task agents (subagent_type=Explore) — one per category or group of categories.

Analysis checklist:

Architecture (SOLID)

  • Files >400 LOC with multiple public types — splitting candidates
  • Modules with >1 responsibility
  • Hard dependencies between modules (concrete types instead of traits)
  • Open/Closed violations: match on types that will be extended

Legitimate exceptions to "1 file = 1 type": Error+ErrorKind pairs, Builder+Target, small private helpers (<30 LOC), related DTO families (Request/Response), typestate marker types, newtype wrapper collections.

Module coupling / cohesion

  • Crate dependency graph: unidirectional? (core ← mid ← app)
  • Circular dependencies between modules within a crate
  • Excessive pub API — types/functions public without necessity
  • Crate knows implementation details of another crate (leaky abstraction)
  • Changing one module cascades breakage into unrelated modules

Duplication (DRY)

  • Repeated code blocks (>5 lines, >2 occurrences)
  • Similar match patterns across different files
  • Copy-pasted error handling

Dead code

  • Unused use, functions, types, constants
  • Commented-out code
  • Unreachable branches

Performance

  • Unnecessary .clone() / .to_string() / .to_owned() where a reference suffices
  • O(n²) loops (nested iterations over collections)
  • Repeated lookups in HashMap/Vec inside a loop
  • Allocations in hot paths

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 is a skill published in the GitHub repository nizovtsevnv/outline-mcp-rs (7 stars, last pushed 8mo ago), licensed MIT. It adds 11 tokens to every session and 1,193 once invoked, about $0.0000 per session on Opus 5.5. 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.
