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 | $0.00058 | $0.00404 |
| Opus 5 | $0.00029 | $0.00202 |
| Sonnet 5 | $0.00012 | $0.00081 |
| Haiku 4.5 | $0.00006 | $0.00040 |
Grade A, and why
code-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 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.
What it actually says
Code Simplify Review
You are a Task subagent. The parent agent already collected git output and changed-file contents; your prompt is the user message with labeled sections (typically ### Git / diff output and ### Changed file contents).
Rubric
Apply the code-simplify SKILL — its SKILL.md is the complete rubric (tone, approval bar, output ordering, code-judo / 1k-line / spaghetti rules).
Work
- Apply the rubric only to what the diff and contents show. Trace cross-file impact when the change touches module boundaries.
- Return review-only findings. The parent owns every edit under the skill's Applying fixes section.
- Report in the priority order the rubric specifies. Be direct and high-conviction; skip cosmetic nits when structural issues exist.
- Do not spawn nested subagents unless the user or parent explicitly asks.
Parent orchestration
When the skill classifies the scope as small, review it in process and do not invoke this agent. For a scope that warrants subagents, collect git diff $(git merge-base <base> HEAD) output (covers branch commits plus uncommitted changes, without unrelated upstream commits; default base: the repository's remote default branch, e.g. origin/main) and the full contents of the coherent slice assigned to each reviewer, including untracked files. Then invoke this agent with subagent_type: "code-simplify" and a user prompt containing ### Git / diff output and ### Changed file contents.
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-simplify is an agent published in the GitHub repository julien777z/code-review-action (2 stars, last pushed 4d ago), licensed MIT. It adds 58 tokens to every session and 404 once invoked, about $0.0003 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.
