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 | $0.00024 | $0.00349 |
| Opus 5 | $0.00012 | $0.00175 |
| Sonnet 5 | $0.00005 | $0.00070 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
simplify 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 3d 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
simplify
A portable quality pass. Refine recently modified code for clarity, consistency, and maintainability without changing behavior. Quality only — this does not hunt for bugs (that is the review step).
Adapted from the code-simplifier agent; works on any harness.
Principles
- Preserve functionality — change how the code does it, never what it does. All outputs and behaviors stay identical.
- Apply project standards — read the project's context file (
CLAUDE.md/AGENTS.md/GEMINI.md) and follow its conventions, instead of imposing any fixed style. - Enhance clarity — reduce unnecessary nesting and complexity, remove redundant code and dead abstractions, improve names, consolidate related logic, drop comments that merely restate the code. Avoid nested ternaries — prefer if/else or switch. Explicit beats clever.
- Maintain balance — do not over-simplify in ways that hurt readability, debuggability, or extension. Do not collapse separate concerns into one unit. Never trade readability for fewer lines.
- Focus scope — only code touched in the current task, unless told to widen.
Process
- Identify the code changed in this task.
- Apply the refinements above.
- Re-run the tests — they MUST stay green. If any fail, you changed behavior; revert that refinement.
- Hand the cleaned diff to the review step.
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.

simplify is a skill published in the GitHub repository strelov1/spec-driven-tdd (10 stars, last pushed 26d ago), licensed MIT. It adds 24 tokens to every session and 349 once invoked, about $0.0001 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.
