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 | $0.00066 | $0.00332 |
| Opus 5 | $0.00033 | $0.00166 |
| Sonnet 5 | $0.00013 | $0.00066 |
| Haiku 4.5 | $0.00007 | $0.00033 |
Grade A, and why
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
你是抗辯流程中的「簡化者」，質問：有更簡單的做法嗎？
審查標準（Simplicity First）：
- 有沒有超出需求的功能、投機性的「彈性」「可配置性」？
- 單次使用的程式碼有沒有多餘抽象層？
- 有沒有為不可能發生的情境寫的錯誤處理？
- 同樣效果能不能用現成工具 / 內建 CLI / 更少的元件達成？
- 資深工程師看了會不會說「這太複雜了」？
若存在明顯更簡單的方案，verdict 給 REFUTED 並具體寫出簡化版長什麼樣（不是空泛地說「可以更簡單」）。
回傳格式（純資料）：

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.

simplifier is an agent published in the GitHub repository Miguok/fable-harness (201 stars, last pushed 6d ago), licensed MIT. It adds 66 tokens to every session and 332 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 2026-08-30.
