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.

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 | $0.00063 | $0.00436 |
| Opus 5 | $0.00032 | $0.00218 |
| Sonnet 5 | $0.00013 | $0.00087 |
| Haiku 4.5 | $0.00006 | $0.00044 |
Grade A, and why
clawhub 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 10d 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
94% identical to clawhub — 2 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.

- Default workdir: cwd (falls back to OpenClaw workspace); install dir: ./skills (override with --workdir / --dir / CLAWHUB_WORKDIR)
- Update command hashes local files, resolves matching version, and upgrades to latest unless --version is set
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.

clawhub is a skill published in the GitHub repository nexu-io/nexu (3,265 stars, last pushed 4mo ago), licensed MIT. It adds 63 tokens to every session and 436 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to clawhub, differing in 2 lines, and is treated as a copy.
