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.

What it costs to keep this loaded
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 | $0.00041 | $0.00463 |
| Opus 5.5 | $0.00016 | $0.00185 |
| Sonnet 5.5 | $0.00008 | $0.00093 |
| Haiku 4.5 | $0.00004 | $0.00046 |
Grade A, and why
common-signal-detector 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 2mo 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
通用：信号检测
将它作为轻量的心智扫描。普通请求中，不要仅因可能存在信号就加载本文件或执行文件读写。每条用户消息都做一次通常不出声的轻量扫描。
检测四类信号
- 原创思考：值得保留的用户原句、模型、判断或连接。
- 实体提及：可能影响实体页的人物、地点、组织、项目、书、媒体、工具或别名。
- 来源更新：日记或来源文件发生变化、新增笔记，或原始材料需要摄取。
- 运行规则更新：用户对 wiki 或 Skill 工作方式的偏好。
路由建议
- 原创思考 -> 建议对话摄取，并路由到相关构建 Skill。
- 实体提及 -> 达到显著性门槛时，建议
build-people或build-life-experience。 - 来源更新 -> 建议日记摄取或来源摄取。
- 规则更新 -> 分析时建议
common-skill-system；用户明确要求修改时建议build-knowledge-adjustment。
捕获规则
- 用户原创表达应保留准确措辞。
- 一次性提及如果不改变解释，不要建页。
- 不要为了宣布捕获信号而打断主任务。
- 除非用户明确要求 wiki 维护，或当前任务已经授权，否则不要写入、追加日志或触发构建 Skill。
- 没有可沉淀信号时，什么都不做。
调试记录
执行明确授权的维护时，在 wiki/log.md 中加入一条简短记录：
Signals: N original, N entities, N source updates, N rule updates
普通消息不要添加调试记录，除非用户要求运行 wiki。
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.

common-signal-detector is a skill published in the GitHub repository lihaozheCharlie/TwhWiki (24 stars, last pushed 2mo ago), licensed MIT.
