/install message-chunker
Description
智能消息分段工具。自动将长消息拆分成多条发送,避免飞书API消息长度限制。当需要发送长消息(如汇报、方案、日志)时自动激活。
Usage Guidance
This skill is instruction-only and internally consistent with its stated purpose. Before installing, verify how your agent sends messages (so you know which messaging integration/credentials will be used) and test behavior with non-sensitive content. Pay attention to retry rules (the doc suggests retrying on Status 400 — you may want to adjust that to avoid repeated client-error retries), decide where the "failure queue" should be stored, and set appropriate maxChunkSize and continuation markers to avoid confusing recipients. If you need stricter behavior (e.g., never splitting tables or excluding sensitive sections), update the configuration in your TOOLS.md and test thoroughly. If you rely on automated sending, ensure the agent's messaging permissions and rate limits are acceptable.
Capability Analysis
Type: OpenClaw Skill
Name: message-chunker
Version: 1.0.0
The 'message-chunker' skill is a utility designed to help an AI agent split long text responses into smaller segments to comply with platform-specific message length limits (e.g., Feishu, Telegram). The bundle consists entirely of documentation and configuration files (SKILL.md, config.yaml, README.md) with no executable code, network activity, or instructions that would lead to data exfiltration or unauthorized access.
Capability Assessment
Purpose & Capability
Name/description (split long messages for platforms like Feishu) aligns with the provided files and runtime instructions; it does not request unrelated credentials, binaries, or config paths.
Instruction Scope
SKILL.md contains only chunking rules, triggers, simple retry guidance, and configuration pointers (TOOLS.md). It does not instruct reading arbitrary files, accessing unrelated environment variables, or sending data to external endpoints.
Install Mechanism
No install spec and no code files are present (instruction-only), so nothing is downloaded or written to disk by the skill itself.
Credentials
The skill declares no environment variables, credentials, or config paths. That is proportionate: chunking logic can run using the agent's existing messaging capabilities without extra secrets.
Persistence & Privilege
always is false and the skill does not request persistent system-wide changes or elevated privileges. Behavior described is limited to message-sending logic within the agent's normal operation.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install message-chunker - After installation, invoke the skill by name or use
/message-chunker - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.0
- Initial release of "message-chunker": an intelligent tool for splitting long messages into multiple parts to avoid Feishu API length limits.
- Automatically triggers when messages exceed 4000 characters, include multiple sections/tables, or message send fails.
- Supports platform-specific length limits for Feishu, Telegram, Discord, and WhatsApp.
- Flexible chunking by section, table, or paragraph, with both automatic and manual chunk markers.
- Configurable behavior via TOOLS.md, including chunk size and splitting preferences.
