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 | $0.00049 | $0.00727 |
| Opus 5.5 | $0.00020 | $0.00291 |
| Sonnet 5.5 | $0.00010 | $0.00145 |
| Haiku 4.5 | $0.00005 | $0.00073 |
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.
How it starts
The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Simplifier
Use this skill for a separate improvement pass over code that already works. It is not part of the default scoped-implementation workflow: the user invokes it deliberately, with existing behaviour, tests, or outputs available to compare against. Be ambitious about simplification, but never change what the code does — only how it does it.
Boundaries
- Preserve functionality exactly. Product behaviour, public contracts, data shapes, test meaning, and accepted edge cases are fixed. If a meaningful simplification would require changing any of them, report it as a recommendation instead of making the change.
- Respect frozen contracts. After an implementation-plan or scoped-implementation workflow, treat the implemented behaviour and its accepted edge cases as part of the contract. Simplification is never a back door for scope expansion.
- Use the requested scope. For a holistic pass, inspect enough surrounding code to simplify the design coherently, and run the
code-healthskill yourself if no report is already supplied — differentially against a base ref when one exists, or--allwhen working on completed/pre-existing code with no diff to compare against — to surface duplication, complexity, and dependency hotspots as evidence before deciding what to simplify. For a narrow request, refine only the named files or functions and skipcode-health.
Standards Come From the Project
Discover conventions rather than importing them: read AGENTS.md, CLAUDE.md, CONTRIBUTING, linter/formatter configuration, and the surrounding code, then match what the project actually does — naming, module layout, error-handling idiom, comment density, import style, test structure. Do not impose conventions from another ecosystem onto this one. When no such doc exists, or the discovered convention is itself inconsistent: if the style-guide skill is also available in the current session, treat its baseline style guide as the fallback; otherwise preserve the narrowest coherent local convention you can find and report the ambiguity rather than guessing or importing a foreign convention.
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 darrencroton/ai-agent-coder (2 stars, last pushed 7d ago), licensed MIT. It adds 49 tokens to every session and 727 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.
