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 | $0.00000 | $0.02995 |
| Opus 5.5 | $0.00000 | $0.01198 |
| Sonnet 5.5 | $0.00000 | $0.00599 |
| Haiku 4.5 | $0.00000 | $0.00299 |
Grade A, and why
notes 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.
This is a copy
100% identical to notes — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Notes (笔记)
⛔ Before ANY write (
import_doc/append_doc): validate ALL string fields (content,title) are legal UTF-8. Non-UTF-8 content causes irreversible garbled text in IMA. See root SKILL.md § MANDATORY RULES for platform-specific validation methods.
API base path: openapi/note/v1
通过 IMA OpenAPI 管理用户个人笔记，支持读取（搜索、列表、获取内容）和写入（新建、追加）。
完整的数据结构和接口参数详见 references/api.md。
隐私规则： 笔记内容属于用户隐私，在群聊场景中只展示标题和摘要，禁止展示笔记正文。
接口决策表
| 用户意图 | 调用接口 | 关键参数 |
|---|---|---|
| 搜索/查找笔记 | search_note |
query_info（QueryInfo 对象） |
| 查看笔记本列表 / 列出笔记本 | list_notebook |
cursor(必填，首页传"0") + limit(必填) |
| 列出笔记/获取多篇笔记信息 | list_note |
folder_id(选填,空为全部) + sort_type + cursor(首次传"") + limit |
| 读取笔记正文 | get_doc_content |
note_id + target_content_format(必填，推荐0纯文本) |
| 新建一篇笔记（用户明确说"新建/创建笔记"时走此接口） | import_doc |
content + content_format(必填，固定1) + 可选 folder_id |
| 往已有笔记追加内容（⚠️ 敏感操作：用户必须明确指定目标笔记，否则先确认再操作） | append_doc |
note_id + content + content_format(必填，固定1) |
⚠️ 新建 vs. 追加 — 行为规则
新建笔记（import_doc） 和 追加内容到已有笔记（append_doc） 是两个完全不同的操作，务必正确区分：
明确走新建的信号词
用户说以下任一表述时，直接调用 import_doc 创建新笔记：
- "新建笔记"、"创建笔记"、"写一篇笔记"
- "新建一篇笔记记录这些内容"
明确走追加的信号词
用户说以下任一表述时，调用 append_doc 追加到已有笔记（但仍需确认目标笔记，见下方规则）：
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.

notes is a skill published in the GitHub repository nexus-research-lab/nexus (152 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 2,995 tokens. A static security scan graded it A with 0 findings. It is 100% identical to notes, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
agent-initialization
Initialize or extend an Agent from a user requirement - write AGENTS.md, set identity metadata, and create, install or import Skills and hook packages (scripts the harness runs on every prompt, before tool calls, or after a task). For an Agent with an in-app workbench, pair with penguin-plugin; for a standalone…
ceo-setup
One-time onboarding for the executive/manager commitment workflow — delegation-heavy, meeting prep, decision capture, morning and evening digests. Creates a commitments project and installs two dashboard widgets. After successful setup this skill is excluded from selection until the marker file is deleted.
commitment-triage
Recognize obligations in conversation, extract signals with immediacy and expiration, create and manage commitments in the workspace.
cron
Schedule, list, pause, resume, edit, or run the user's agentica cron jobs with the cronjob tool. Use when asked to remind, schedule a recurring or one-shot task, try a job now, or manage jobs that fire unattended.
routine-advisor
Suggests relevant cron routines based on user context, goals, and observed patterns.
delegation
Helps users delegate tasks, break them into steps, set deadlines, and track progress via routines and memory.
