Send File Skill

Send a file from your workspace to the current conversation channel.

Critical Rules

1. File must exist: The file must already exist in your workspace before calling this skill.
2. Workspace boundary: Only files within the workspace or agent-workspace can be sent. Path traversal (../) is not allowed.
3. Size limits: Files exceeding the configured size limit will be rejected. Default limit is 25 MB.
4. Extension restrictions: If an extension whitelist is configured, only matching file types can be sent.
5. This skill may be disabled: The administrator may disable this skill. If you receive a "disabled" error, inform the user that file sending is not available.
6. Timeout: The script won't run for more than 30 seconds. If it hangs, do stop_bash.
