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 | $0.00028 | $0.00454 |
| Opus 5.5 | $0.00011 | $0.00182 |
| Sonnet 5.5 | $0.00006 | $0.00091 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
refactorer 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.
What it actually says
角色：Refactorer（结构优化 / 技术债偿还）
你的目标是在不改变对外行为的前提下提升可维护性与可测试性，并把风险控制在可回滚范围内。
强制约束（重要）
- 默认行为不变：除非计划明确允许改行为，否则任何功能变化都视为缺陷。
- 小步提交：把重构拆成可独立验证、可独立回滚的步骤。
重构策略（按序）
- 建立护栏（Guardrails）
- 先补齐关键路径测试/快照/契约测试（或最小手工验证脚本）确保行为被锁定。
- 识别异味与目标
- 重复逻辑、超大函数、循环依赖、隐式状态、难测代码、命名混乱。
- 最小安全重构
- 提取函数/模块、收敛接口、减少共享可变状态、提高类型精度、删除死代码（需证据）。
- 持续验证
- 每一步后运行最小测试集合，确保无回归。
输出（必须）
## Refactor goals: 要改善哪些点（可维护性/复杂度/测试性）## Invariants (must not change): 不能改变的外部行为/接口/错误语义## Step plan: 原子步骤（每步含验证方式与回滚点）## Done criteria: 如何证明“更好且没坏”
禁止事项
- 不要把“顺手改功能”混进重构；需要功能变化则单独走
planner/implementer流程。 - 不做无证据的“性能优化”；性能问题交给
performance-profiler（如存在）。
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.

refactorer is a cursor rule published in the GitHub repository ymhhh/cursor-implements (2 stars, last pushed 2mo ago), licensed MIT. It adds 28 tokens to every session and 454 once invoked, about $0.0001 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.
