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 5.1 | $0.00054 | $0.05264 |
| Opus 5 | $0.00027 | $0.02632 |
| Sonnet 5 | $0.00011 | $0.01053 |
| Haiku 4.5 | $0.00005 | $0.00526 |
Grade A, and why
refactoring-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 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.
How it starts
The opening of the file, as written. The whole thing — 842 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Refactoring Assistant Skill
This skill guides systematic code improvement through proven refactoring techniques. Use this whenever you need to clean up code, reduce technical debt, improve structure, or apply better design patterns.
Core Refactoring Principles
1. SOLID Principles
| Principle | Description | Violation Signs |
|---|---|---|
| Single Responsibility | One class = one reason to change | Large classes, mixed concerns |
| Open/Closed | Open for extension, closed for modification | Frequent edits to existing code |
| Liskov Substitution | Subtypes must be substitutable | Broken inheritance, type checks |
| Interface Segregation | Many specific interfaces > one general | Fat interfaces, unused methods |
| Dependency Inversion | Depend on abstractions, not concretions | Hard-coded dependencies |
2. DRY (Don't Repeat Yourself)
- Eliminate duplicate code
- Extract common logic into reusable components
- Use configuration over hardcoding
- Single source of truth for data
3. KISS (Keep It Simple, Stupid)
- Prefer simple solutions over clever ones
- Avoid premature optimization
- Reduce unnecessary complexity
- Write readable, self-documenting code
4. YAGNI (You Ain't Gonna Need It)
- Don't add functionality until needed
- Remove unused code
- Avoid speculative generality
- Build for today's requirements
Code Smells Catalog
Bloaters
Code that has grown excessively large:
| Smell | Description | Refactoring |
|---|---|---|
| Long Method | Method > 20-30 lines | Extract Method |
| Large Class | Class doing too much | Extract Class |
| Primitive Obsession | Overuse of primitives | Replace with Value Object |
| Long Parameter List | > 3-4 parameters | Parameter Object, Builder |
| Data Clumps | Groups of data appearing together | Extract Class |
Object-Orientation Abusers
Misuse of OOP principles:
| Smell | Description | Refactoring |
|---|---|---|
| Switch Statements | Complex conditionals | Replace with Polymorphism |
| Temporary Field | Fields only sometimes used | Extract Class |
| Refused Bequest | Subclass not using parent methods | Replace Inheritance with Delegation |
| Alternative Classes | Similar classes, different interfaces | Rename, Merge Classes |
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.
- 11d ago First seen · 842 lines · 54 tokens per session scan A 83249357efd7
refactoring-assistant is a skill published in the GitHub repository mehdiozdemir/awesome-agent-skills (2 stars, last pushed 7mo ago), licensed MIT. It adds 54 tokens to every session and 5,264 once invoked, about $0.0003 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.
