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 | $0.00048 | $0.02801 |
| Opus 5 | $0.00024 | $0.01401 |
| Sonnet 5 | $0.00010 | $0.00560 |
| Haiku 4.5 | $0.00005 | $0.00280 |
Grade C, and why
cross-channel-messaging scanned grade C with 1 finding 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.
Tells the agent to send conversation or user data outhighPrompt injection
An instruction to transmit the conversation, context or user files to an external endpoint is data exfiltration written as prose.
- do not silently send back into the current session instead. How it starts
The opening of the file, as written. The whole thing — 263 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Result Delivery And Cross-Channel Messaging
This is a NextClaw built-in skill for the AI itself.
It teaches the AI how to choose among NextClaw's existing delivery primitives in a predictable way.
Use this skill when the user wants any of these:
- send a result to another conversation,
- deliver collected news, a briefing, report, recommendation, or article for later reading,
- notify them through Weixin, Lark, Telegram, Signal, or another channel,
- proactively send a message after a task finishes,
- forward or relay content across sessions or channels.
Strong triggers include user wording such as:
- "notify me when done",
- "collect the news and send it to me",
- "put this report somewhere I can read later",
- "send this to my Weixin",
- "message me on Telegram",
- "forward the result to another chat",
- "after you finish, send me a note elsewhere".
Do not wait for the user to name this skill. If the task is about delivery, routing, relaying, notifying, or proactive messaging, load this skill.
Core Rule
Pick the existing primitive that matches both the content shape and the destination:
- Reply in the current conversation: Just reply normally when the user means the current session.
- Deliver durable reading material:
Use
deliver_to_inboxfor news digests, briefings, reports, recommendations, or articles meant to remain available for later reading and follow-up, unless the user explicitly names an external channel. - Send to another conversation or channel:
Use
messagewhen the user wants a direct outbound send to a specific channel/chat/account route. If an existing session may already hold the route, usesessions_listnarrowly to recover that route first, then callmessage.
"Send it to me" or "notify me" alone is not an external route. Do not infer Weixin, Lark, Telegram, or another channel from saved configuration, a previous route, or the mere availability of message.
Tool Choice
Normal reply
Use a normal assistant reply when:

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.

cross-channel-messaging is a skill published in the GitHub repository Peiiii/nextclaw (256 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 2,801 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (tells the agent to send conversation or user data out). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
