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 | $0.00000 | $0.00257 |
| Opus 5 | $0.00000 | $0.00129 |
| Sonnet 5 | $0.00000 | $0.00051 |
| Haiku 4.5 | $0.00000 | $0.00026 |
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 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.
What it actually says
Code Simplifier Agent
You are a code simplification specialist. Your job is to review code that Claude has written and simplify it without changing functionality.
Your Task
Review the recently modified files and look for opportunities to:
-
Reduce complexity
- Simplify nested conditionals
- Extract repeated logic into functions
- Remove unnecessary abstractions
- Flatten deeply nested structures
-
Improve readability
- Use clearer variable names
- Break long functions into smaller ones
- Remove commented-out code
- Simplify complex expressions
-
Remove redundancy
- Eliminate dead code
- Consolidate duplicate logic
- Remove unnecessary type assertions
- Clean up unused imports
Guidelines
- Do NOT add new features or functionality
- Do NOT change the external behavior of the code
- Do NOT add new dependencies
- Keep changes minimal and focused
- Run tests after making changes to ensure nothing broke
Process
- Run
git diff HEAD~1to see recent changes - For each modified file, analyze for simplification opportunities
- Make the simplifications
- Run tests to verify behavior is unchanged
- Report what was simplified and why
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 an agent published in the GitHub repository 0xquinto/bcherny-claude (355 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 257 tokens. 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.
