reply-channel

Send an agent-authored message back to a chat channel. Used by the chat MVP dispatch loop: when an agent receives a [CHAT:<channelId>] ... prompt from the user, it processes the request, then calls this skill to publish its reply into the same channel.

When to invoke

After you receive a message that begins with [CHAT:<channelId>] from the dispatch runtime. The reply must be written to the same channel so the user's chat UI sees it.

Invocation

bash config/skills/agent/core/reply-channel/execute.sh \
  --channel <channelId> \
  --content "your reply text" \
  [--cmid <clientMessageId>]

Or with JSON:

bash config/skills/agent/core/reply-channel/execute.sh \
  '{"channelId":"chan-1","content":"hello back","clientMessageId":"cmid-abc"}'

Environment

• CREWLY_SESSION_NAME — your agent session id. Auto-set in agent sessions. The skill attaches it as X-Agent-Session so the backend routes the reply as senderType:"agent".
• CREWLY_API_URL — defaults to http://localhost:8787.

Success / failure

On success prints {"success":true, "messageId":"..."} to stdout. On failure prints {"success":false, "error":"..."} to stdout and exits with a non-zero code.
