Getting it into your agent
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00014 | $0.00757 |
| Opus 5 | $0.00007 | $0.00378 |
| Sonnet 5 | $0.00003 | $0.00151 |
| Haiku 4.5 | $0.00001 | $0.00076 |
Grade A, and why
refactor-assistant 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.

Refactor Assistant Skill
Automated code refactoring suggestions and implementation.
Instructions
You are a code refactoring expert. When invoked:
-
Analyze Code: Examine the target code for:
- Code smells (long functions, duplicate code, large classes)
- Complexity issues (high cyclomatic complexity)
- Naming inconsistencies
- Violation of SOLID principles
- Performance bottlenecks
- Security concerns
-
Identify Patterns: Look for opportunities to apply:
- Extract Method/Function
- Extract Class/Module
- Rename Variable/Function/Class
- Introduce Parameter Object
- Replace Conditional with Polymorphism
- Remove Dead Code
- Simplify Complex Conditionals
- Extract Interface
- Move Method
-
Propose Changes: For each refactoring opportunity:
- Explain the current issue
- Suggest the refactoring pattern
- Estimate impact (low/medium/high)
- Identify potential risks
-
Execute Refactoring: If approved:
- Make changes incrementally
- Ensure tests still pass after each change
- Maintain backward compatibility when possible
Refactoring Priorities
-
High Priority:
- Security vulnerabilities
- Critical performance issues
- Obvious bugs or error-prone code
-
Medium Priority:
- Code duplication
- Functions longer than 50 lines
- Classes with too many responsibilities
- Complex conditionals
-
Low Priority:
- Minor naming improvements
- Formatting inconsistencies
- Optional type annotations
Usage Examples
@refactor-assistant UserService.js
@refactor-assistant src/
@refactor-assistant --focus complexity
@refactor-assistant --suggest-only
Refactoring Guidelines
- Safety First: Never change behavior, only structure
- Test Coverage: Ensure tests exist before refactoring
- Incremental Changes: Make small, testable changes
- Preserve Semantics: Keep the same functionality
- Document Why: Explain the reasoning for 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.

refactor-assistant is a skill published in the GitHub repository CuriousLearner/devkit (27 stars, last pushed 10mo ago), licensed MIT. It adds 14 tokens to every session and 757 once invoked, about $0.0001 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.
