nexu is an open-source desktop client that connects an OpenClaw AI agent to messaging services such as WeChat, Feishu, Slack, and Discord. It is for people who want to chat with their agent from those channels using their own model credentials while keeping data on their computer, and the catalogue entries support its agent workflows.
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 | $0.00033 | $0.02722 |
| Opus 5 | $0.00016 | $0.01361 |
| Sonnet 5 | $0.00007 | $0.00544 |
| Haiku 4.5 | $0.00003 | $0.00272 |
Grade A, and why
feishu-calendar 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 12d 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.

🚨 执行前必读
- ✅ 时区固定：Asia/Shanghai（UTC+8）
- ✅ 时间格式：ISO 8601 / RFC 3339（带时区），例如
2026-02-25T14:00:00+08:00 - ✅ create 最小必填：summary, start_time, end_time
- ✅ user_open_id 强烈建议：从 SenderId 获取（ou_xxx），确保用户能看到日程
- ✅ ID 格式约定：用户
ou_...，群oc_...，会议室omm_...，邮箱email@...

🎯 核心约束（Schema 未透露的知识）
1. user_open_id 为什么必填？
工具使用用户身份：日程创建在用户主日历上，用户本人能看到。
但为什么还要传 user_open_id：将发起人也添加为参会人，确保：
- ✅ 发起人会收到日程通知
- ✅ 发起人可以回复 RSVP 状态（接受/拒绝/待定）
- ✅ 发起人出现在参会人列表中
- ✅ 其他参会人能看到发起人
如果不传：
- ⚠️ 用户能看到日程，但不会作为参会人
- ⚠️ 如果只有其他参会人，发起人不在列表中（不符合常规逻辑）
2. 参会人权限（attendee_ability）
工具已默认设置 attendee_ability: "can_modify_event"，参会人可以编辑日程和管理参与者。
| 权限值 | 能力 |
|---|---|
none |
无权限 |
can_see_others |
可查看参与人列表 |
can_invite_others |
可邀请他人 |
can_modify_event |
可编辑日程（推荐） |
3. 统一使用 open_id（ou_...格式）
- ✅ 创建日程：
user_open_id = SenderId - ✅ 邀请参会人：
attendees[].id = "ou_xxx" - ✅ 删除参会人：
user_open_ids = ["ou_xxx"]（工具已优化，直接传 open_id 即可）
⚠️ ID 格式区分：
ou_xxx：用户的 open_id（你应该使用的）user_xxx：日程内部的 attendee_id（list 接口返回，仅用于内部记录）
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.
- 12d ago First seen · 256 lines · 33 tokens per session scan A 7d879d14b956
feishu-calendar is a skill published in the GitHub repository nexu-io/nexu (3,266 stars, last pushed 4mo ago), licensed MIT. It adds 33 tokens to every session and 2,722 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.
