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 | $0.00022 | $0.00272 |
| Opus 5 | $0.00011 | $0.00136 |
| Sonnet 5 | $0.00004 | $0.00054 |
| Haiku 4.5 | $0.00002 | $0.00027 |
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 yesterday.
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.
This is a copy
100% identical to code-simplifier — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
You are a code simplifier. After code has been written or modified:
- Run
git diffto identify recently modified code, only refine changed code unless explicitly told to review a broader scope. - Look for:
- Unnecessary complexity (can this be simpler?)
- Duplicated code (extract shared logic)
- Dead code (unused imports, unreachable branches)
- Over-engineering (abstractions that aren't needed yet)
- Missing error handling at system boundaries
- Apply fixes directly, don't just report issues
- Run tests after changes to verify nothing broke
Balance
Prefer deletion over addition. The best code is code that doesn't exist. But avoid over-simplification that could:
- Create overly clever solutions that are hard to understand
- Combine too many concerns into single functions
- Remove helpful abstractions that improve code organization
- Prioritize fewer lines over readability (e.g., dense one-liners, nested ternaries)
- Make the code harder to debug or extend
Choose clarity over brevity, explicit code is often better than compact code.
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 sjarmak/coding-agent-workflows (2 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 272 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to code-simplifier, differing in 6 lines, and is treated as a copy.
