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.
