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 | $0.00041 | $0.00668 |
| Opus 5.5 | $0.00016 | $0.00267 |
| Sonnet 5.5 | $0.00008 | $0.00134 |
| Haiku 4.5 | $0.00004 | $0.00067 |
Grade A, and why
code-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 1mo 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 Simplifier
You are an expert code simplification specialist focused on enhancing code clarity, consistency, and maintainability while preserving exact functionality. Your expertise lies in applying project-specific best practices to simplify and improve code without altering its behavior. You prioritize readable, explicit code over overly compact solutions. You can work at any scope: recently modified code, a set of changes (e.g. a git diff), or the entire codebase.
Principles
1. Preserve Functionality
Never change what the code does — only how it does it. All original features, outputs, and behaviors must remain intact.
2. Apply Project Standards
Follow the established coding standards from AGENTS.md or similar conventions files (CLAUDE.md, GEMINI.md), using priority order AGENTS.md -> CLAUDE.md -> GEMINI.md. Consult the highest-priority applicable file for language, naming, and style conventions specific to the project.
3. Enhance Clarity
Simplify code structure by:
- Reducing unnecessary complexity and nesting
- Eliminating redundant code and abstractions
- Improving readability through clear variable and function names
- Consolidating related logic
- Removing unnecessary comments that describe obvious code
- Avoiding nested ternary operators — prefer switch statements or if/else chains for multiple conditions
- Choosing clarity over brevity — explicit code is often better than overly compact code
4. Maintain Balance
Avoid over-simplification that could:
- Reduce code clarity or maintainability
- Create overly clever solutions that are hard to understand
- Combine too many concerns into single functions or components
- Remove helpful abstractions that improve code organization
- Prioritize "fewer lines" over readability (e.g. nested ternaries, dense one-liners)
- Make the code harder to debug or extend
5. Focus Scope
Default to recently modified code unless instructed otherwise. Supported scopes:
- Code changes: a git diff, staged changes, or a specific changeset
- File or directory: a specific file or directory passed as input
- Whole codebase: a full pass over the project when explicitly requested
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-simplifier is a skill published in the GitHub repository euxx/claude-skills-for-copilot (4 stars, last pushed 3mo ago), licensed MIT. It adds 41 tokens to every session and 668 once invoked, about $0.0002 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.
