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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00042 | $0.00577 |
| Opus 5 | $0.00021 | $0.00289 |
| Sonnet 5 | $0.00008 | $0.00115 |
| Haiku 4.5 | $0.00004 | $0.00058 |
Grade A, and why
summarizer 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 6d 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.

内容摘要指南
从已有来源提取关键信息生成结构化摘要。核心约束：每个观点必须能在原文找到对应段落，不添加原文没有的推断。
适用场景
- URL 网页摘要（"这个链接讲了什么"）
- 本地文件（PDF / 文档 / 代码）摘要
- 会议纪要整理（录音转写后的会议记录）
- 多文档对比（找共识 / 分歧）
- 长文精简（保核心、删枝叶）
不适用场景
- 从零创作 → content-creator
- 数据统计报告 → data-analyst
- 跨多源调研 → research-assistant

通用要点：
- 选格式：短摘要（3-5 句） / 深度摘要（章节结构） / 会议纪要（议题 / 决议 / 行动项 / 责任人） / 多文档对比（共识 / 分歧 / 来源标注）
- 抓不全要声明：抓取空 / 不全 / 被付费墙挡时告知用户，不假装抓了全部
- 多文档对比：每篇逐一读取后再生成，不靠单文档外推
- 来源标注：URL 摘要开头

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

summarizer is a skill published in the GitHub repository ntygod/ZhiWei (137 stars, last pushed 26d ago), licensed MIT. It adds 42 tokens to every session and 577 once invoked, about $0.0002 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.
Other skills, from other repositories
inbox-triage
Summarize unread Gmail messages Alfred Core has already synced, and offer to draft or schedule follow-up actions -- never sends or deletes anything on its own.
morning-brief
Render Alfred Core's deterministic morning brief and deliver a short, warm rewrite of it without changing any fact, date, or link it contains.
weekly-review
Pull together the week's open tasks, GitHub notifications, Canvas missing assignments, and remembered context into one retrospective-style summary.
docmancer
Work from the same local memory as every other coding agent on this machine. Recall prior decisions, preferences, instructions, and project conventions that Claude Code, Codex, Cursor, and other agents wrote here, with cited sources, fully local. Also searches a separate local technical-documentation index.
vault-for-llm
Connect OpenClaw to Vault Agent Memory as a local-first governed project memory layer. Search first, then bounded-read cited source ranges; propose new memories as candidates instead of writing directly into active memory.
mooncite
Use when an agent needs past Pi, OMP, Claude Code, Codex, or ChatGPT context.
