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 | $0.00022 | $0.00623 |
| Opus 5 | $0.00011 | $0.00311 |
| Sonnet 5 | $0.00004 | $0.00125 |
| Haiku 4.5 | $0.00002 | $0.00062 |
Grade A, and why
feedback 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Feedback
Collect user feedback and forward it to the Nexu team. Conversation history and images are extracted automatically by a script — you do NOT need to copy-paste messages or scan for image URLs.
When triggered
The user sends /feedback <message> to share feedback, report issues, or make suggestions about the Nexu platform.
Steps
-
Extract feedback content: The text after
/feedbackis the user's feedback. If empty, ask the user to provide their feedback. -
Gather identifiers:
- agentId: Your own agent ID. Find it from the
Runtime:line in your system prompt — it appears asagent=XXXXXX. It is a cuid2 string likey9cnvdlucvyaokp20mqrsoa9. Do NOT use "main" or other placeholder values. - channel: The current channel type — one of
feishu,slack, ordiscord. - sender: The sender's display name or username as shown in the conversation. If you only have a user ID, use that. Do NOT use generic "user" or "User".
- agentId: Your own agent ID. Find it from the
-
Run the submit script: Use the exec tool to run the following command. The script automatically reads your conversation history and any images from the session file — you do NOT need to provide them manually.
SKILL_PATH="<SKILL_LOCATION>"
node "$(dirname "${SKILL_PATH/#\~/$HOME}")/submit-feedback.mjs" \
--content "<ESCAPED_FEEDBACK>" \
--sender "<SENDER>" \
--channel "<CHANNEL_TYPE>" \
--agent-id "<AGENT_ID>"
Important:
- Replace
<SKILL_LOCATION>with the exact path from the<location>tag in your system prompt (may contain~) - The
${SKILL_PATH/#\~/$HOME}expansion handles tilde (~) → absolute path conversion automatically - Replace ALL other
<...>placeholders with actual values BEFORE running the command - Properly escape shell special characters in the feedback content (single quotes →
'\'', etc.)
- Confirm to user:
- If the output contains
{"ok":true}, reply: "Thanks for your feedback! It has been forwarded to the Nexu team." - If it fails, reply: "Sorry, there was an issue sending your feedback. Please try again later."
- If the output contains
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.

feedback is a skill published in the GitHub repository nexu-io/nexu (3,264 stars, last pushed 4mo ago), licensed MIT. It adds 22 tokens to every session and 623 once invoked, about $0.0001 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.
