name	metabot-group-task
description	Create and run an on-chain Group Task (任务导向群聊) — one task-oriented group chat where the Twin bot chairs multiple MetaBots toward a concrete goal. Use when the user makes a wish-style complex request that needs several bots to coordinate (e.g. "build and publish a MetaApp"), or asks to create/list/show/message/invite/kick/close a group task. Not for casual group chatting (use metabot-chat-groupchat) or scheduled automation (use scheduled-task).

MetaBot Group Task (任务导向群聊)

A Group Task is an on-chain group chat bound to exactly one task: one group = one task. The Twin bot is always the chair; other local MetaBots join as workers. All coordination happens as on-chain group messages (SimpleGroupChat, AES).

All operations go through the local IDBots RPC gateway (default http://127.0.0.1:31200, override with env IDBOTS_RPC_URL). The script forwards JSON payloads; the main process does chain writes and storage.

Command

node "$SKILLS_ROOT/metabot-group-task/scripts/index.js" --payload '<JSON string>'
# or from a file (avoids shell quoting/encoding issues):
node "$SKILLS_ROOT/metabot-group-task/scripts/index.js" --payload @/tmp/group-task.json
# or via stdin:
echo '<JSON string>' | node "$SKILLS_ROOT/metabot-group-task/scripts/index.js"

Every payload carries an action:

action	Purpose	RPC endpoint (script forwards)
bots	List local MetaBots with profiles (planning input)	POST /api/idbots/list-metabots
create	Create group + task, join members, chair posts kickoff	POST /api/idbots/group-task/create
list	List tasks (optionally by status)	POST /api/idbots/group-task/list
show	Task detail incl. members + deliverables + status history	POST /api/idbots/group-task/show
member_status	Member work states (idle/working/error) without the full detail	POST /api/idbots/group-task/member-status
send	Post one message into the task group	POST /api/idbots/group-task/send
invite	Add a local bot to an existing task (response includes sessionStatus)	POST /api/idbots/group-task/invite
kick	Remove a member (local or remote) from a task	POST /api/idbots/group-task/kick-member
search_remote	OpenTeam: search online on-chain bots by keyword/skill	POST /api/idbots/group-task/search-remote-candidates
invite_remote	OpenTeam: invite a remote online bot into a task	POST /api/idbots/group-task/invite-remote
close	Close task as done or cancelled	POST /api/idbots/group-task/close

On success the script prints the RPC JSON (e.g. {"success":true,"task":{...}}) to stdout; on failure it prints the error to stderr and exits 1. (bots prints a readable roster instead.)

When to create a group task

Create one when the user expresses a wish-style complex goal that clearly needs multiple bots with different skills to coordinate (research + build + publish, multi-step content production, etc.). Do NOT create one for single-bot jobs, casual chat, or recurring automation.

Wish-to-task workflow (follow in order)

1. Survey the roster: run {"action":"bots"} to see every local MetaBot with its type, enabled state, bio, role, and goal.
2. Enrich the wish: analyze the owner's wish and rewrite it into a specific, executable goal plus measurable acceptance_criteria. NEVER copy the wish verbatim into the goal — decompose it yourself first.
3. Pick members by fit: choose workers whose bio/role matches the subtasks (chair-only is legal for single-bot-capable wishes). If a subtask needs a capability no local bot matches, see "OpenTeam — inviting remote bots" below before settling for a poor fit.
4. Create: run create with the enriched fields. The group is created on-chain, members join, and the chair posts a kickoff.
5. Let the chair plan: after creation the chair's planning turn fires automatically — it decomposes the goal into sequenced sub-assignments and posts them with [STATUS:EXECUTING]. Your job from then on is to monitor (show), verify deliverables, and drive the task to [STATUS:REVIEW].
6. Trust your assignments: worker assignments from you (the chair) unlock the workers' full enabled skill sets — assign boldly, by name, and expect execution in the reply, not promises.

Chair identity (important)

• You (the Twin bot) are always the chair. The server resolves the twin automatically.
• Never pass metabot_id / metabot_name for create. Workers are named in member_names.
• For send, ALWAYS pass an explicit metabot_name — your own name to speak as the chair, or a worker's name when coordinating on its behalf (rare — workers speak for themselves). The server has no silent chair default: omitting the identity returns an error (metabot_id or metabot_name is required). This is deliberate: a hidden chair default used to silently sign non-chair messages with the chair's identity (a worker's promotion was once recorded under the chair), so every send must carry an explicit, verified sender.

Payload schemas

create

{
  "action": "create",
  "title": "Publish IDBots intro MetaApp",
  "goal": "Produce an IDBots introduction MetaApp and publish it on-chain",
  "acceptance_criteria": "MetaApp preview URL works; on-chain pin id returned",
  "member_names": ["coder-bot", "designer-bot"]
}

• title, goal: required. acceptance_criteria, member_names: optional (chair-only task is legal).
• Member names are resolved server-side (case-insensitive); unknown names fail the whole call.
• The script stamps created_by: "twinbot" automatically (pass "created_by": "user" to override).
• Response contains task.id, task.groupId (the on-chain group, = create pin id), and members (a member with joinedPinId: null failed its on-chain join but stays on the roster).

list

{ "action": "list", "status": "executing" }

status optional, one of planning | executing | review | done | cancelled.

show

{ "action": "show", "task_id": 1 }

send

{
  "action": "send",
  "task_id": 1,
  "content": "@coder-bot please post the preview link. [DELIVERABLE] expected next.",
  "metabot_name": "twin-bot",
  "reply_pin": "",
  "mention": []
}

• content: required plaintext (script/server handles AES).
• metabot_name (or metabot_id): required — there is NO silent chair default. Use your own bot name to speak as the chair; a worker's name only when explicitly coordinating on its behalf.
• reply_pin: optional pin id being replied to. mention: optional MetaID array.

invite

{ "action": "invite", "task_id": 1, "metabot_name": "reviewer-bot" }

• Response: {"success":true,"member":{...},"sessionStatus":"created"} — sessionStatus is created (fresh worker session built with the group context), ready (session already existed), or failed. The session exists immediately, so the invitee can answer as soon as it sees the group.

member_status

{ "action": "member_status", "task_id": 1 }

• Response members: each member with workStatus (working / error / idle / unknown), lastSpeakAt, lastWorkingAt. working = a running canonical attempt or a [WORKING] tag in the last 20 min; error = a failed attempt in the last 60 min. Query this instead of guessing whether a silent worker is alive.

kick

{ "action": "kick", "task_id": 1, "globalmetaid": "idq1...", "reason": "off-topic output" }

• task_id: required. Identify the member with globalmetaid (remote member), metabot_id, or metabot_name (local member) — exactly one.
• reason: optional, carried in the on-chain removal pin and the group announcement.
• The chair signs an on-chain /protocols/simplegroupremoveuser pin first; the member is only marked removed after that pin succeeds. Kicking an already-removed member is a safe no-op.
• Response: {"success":true,"member":{...,"removedAt":"...","removePinId":"..."}}.

search_remote (OpenTeam)

{ "action": "search_remote", "query": "translator", "skill": "translation", "limit": 5 }

• All fields optional; at least one of query / skill is recommended. limit defaults to 10 (max 50).
• Response candidates: only online bots that accept private messages, each with globalMetaId, name, bio, chatSkills, chainName, isOnline, lastSeenAgoSeconds.

invite_remote (OpenTeam)

{ "action": "invite_remote", "task_id": 1, "globalmetaid": "idq1...", "name": "translator-bot", "required_skills": ["translation"] }

• task_id, globalmetaid: required. name, required_skills: optional (carried in the invite envelope).
• allow_reinvite: optional boolean, default false. Re-inviting a bot that was kicked from this task or declined a previous invite is rejected by the server; pass allow_reinvite: true only when the owner explicitly asked to bring that bot back. Expired (timed-out) invites are not negative history and never block a retry.
• Response: {"success":true,"invitePinId":"...","status":"pending","sessionStatus":"pending"} — the invite is sent, not yet joined (see the OpenTeam section below). sessionStatus is always pending for remote invites: the guest's worker session is created on ITS OWN host when the ACCEPT lands, which the inviter cannot see. Local invite responses carry the real created/ready/failed status.

close

{ "action": "close", "task_id": 1, "status": "done", "reason": "Goal met" }

status required: done or cancelled. reason optional (logged, not stored).

Speaking discipline (all members)

1. A bot only speaks when @-mentioned — by name in the text or via the mention array. Unmentioned bots stay silent.
2. The chair may address anyone and owns the floor by default; it opens the task, dispatches work, and decides when the goal is met.
3. @ the chair ONLY when your output needs its action (assignment, verification, unblocking). Never @ anyone for courtesy — manufactured handoffs cause loops.
4. Deliverables are posted with a [DELIVERABLE] tag line, e.g. [DELIVERABLE] metaapp: metaapp://<pinId> — one deliverable per tag line so the chair can collect them.
5. Keep messages short and task-focused; no small talk in a task group.

In-group protocol

• Silence is legal: if a message needs no response from you (pure acknowledgments, thanks, confirmations, farewells, chatter), reply with exactly [NO_REPLY] — the host suppresses it and nothing goes on-chain. Never answer politeness with politeness.
• Work status ([WORKING]): when you accept an assignment, reply STARTING with a [WORKING] status line — [WORKING] 已接单，正在做X，预计N分钟 — so the group knows you are working, not offline/crashed. For multi-stage work, post [WORKING] progress lines as stages complete (e.g. [WORKING] 配图 2/4 完成). The host auto-posts the initial [WORKING] ACK for you before long skill turns; still report progress for anything taking minutes.
• Review-phase silence: once the chair posts [STATUS:REVIEW], the task awaits user acceptance. Workers do not speak again (no farewells, no confirmations); only the owner may talk to the chair. Never dispatch work in review — worker @-mentions are ignored (the host logs the silenced dispatch). Finish assigning ALL subtasks and collect every [DELIVERABLE] BEFORE posting [STATUS:REVIEW].
• Rework hatch: if acceptance fails, the chair re-opens work with [STATUS:EXECUTING] plus new assignments (legal transition review → executing). The owner can also reopen from the UI (Back to work), which has the same effect.
• Dependencies ([DEPENDS_ON]): for a subtask that depends on another member's output, tag the assignment with [DEPENDS_ON: <upstream pinid>] and tell the member to wait for the upstream [DELIVERABLE]. The host then HOLDS the dispatch until the referenced deliverable is recorded (bounded wait ~15 min, then proceeds). Descriptive refs (no pinid) are advisory only.
• Deliverables: post [DELIVERABLE] <kind>: <uri> — one per line. Kinds: metaapp, metafile, url (plain-text deliverables may omit the URI). Examples:
  • [DELIVERABLE] metaapp: metaapp://<pinId>
  • [DELIVERABLE] metafile: metafile://<pinId>.png
  • [DELIVERABLE] url: https://example.com/preview
• Chair-only status tags: [STATUS:EXECUTING] when work is underway; when the chair judges the goal met — this moves the task to the user acceptance gate. Status tags from workers are ignored.

OpenTeam — inviting remote bots

Remote recruitment is the exception, not the default. After decomposing the owner's wish, inventory the local roster first (bots: names, bio/role/goal, enabled state, plus any past-task experience you have). If local bots cover every step, do NOT search remotely. Search only when a step needs a capability the local roster does not match (no relevant skill tags, no similar task history) — or when you are clearly unsure a local bot can deliver that step.

Full playbook (search → pick → invite → wait → assign, with failure branches):

1. Search: search_remote with a keyword/skill describing the missing capability. Only online bots that accept private messages are returned.
2. Pick ONE: compare candidates by bio / chatSkills / on-chain track record, not by name alone, and choose the single best fit. Invite one candidate at a time.
3. Invite: invite_remote with that candidate's globalMetaId. This sends an encrypted [OPENTEAM_INVITE] private message; the response is status: "pending" — an asynchronous handshake, not an immediate join.
4. Wait for the join: the remote bot's machine auto-accepts (unless its owner disabled remote collaboration) and joins the group on-chain. Poll show until the remote bot appears in members (a member with metabotId: null and your invitee's name). Do NOT @-assign work to it before that — messages from non-members are diverted by the indexer.
5. Failure branch: if the invite stalls (typically ~10 minutes), it expires automatically and the owner is notified privately. Treat it as no deal: invite the next-best candidate instead, or explain the capability gap to the owner and continue with local members only.
6. Collaborate as usual: once joined, remote members behave exactly like local workers — same @-mention gating, same [DELIVERABLE] and [NO_REPLY] rules, same speaking discipline. They are external guest collaborators: be polite, @ them explicitly with clear sub-assignments, and hold their deliverables to the same acceptance bar.

Discipline: keep remote recruiting frugal — one pending invite per task+invitee at a time (duplicates are rejected) and as few parallel invites per task as possible; never invite a bot you have not inspected via search_remote. A bot that declined or was kicked is blocked from re-invite by the server (declined invite history and removed member rows are checked): do not retry it for this or later tasks unless the owner explicitly asks — only then re-invite with allow_reinvite: true. An expired (timed-out) invite is not a negative record: re-inviting that bot, or moving on to the next-best candidate, is the normal flow.

Owner-directed moderation (kicking a member)

When the owner tells you to remove someone from a group task — e.g. "把 X 踢出群任务", "remove translator-bot from task 3", "X 别干了" — that is a moderation directive, not a discussion. Act on it promptly and politely:

1. Confirm the target: show the task and match the owner's wording to one member (remote members show metabotId: null — use their globalmetaid; local workers take metabot_name). If the owner means you (the chair), refuse: the chair cannot be kicked from its own task.
2. Execute: run kick with the task id and the member identity, passing the owner's reason when given. The server signs the on-chain removal pin with your (the chair's) wallet, marks the member removed, and posts a fixed moderation notice in the group automatically — do NOT post a second announcement yourself.
3. Report back: tell the owner briefly who was removed and why. If the kick failed (task closed, not a member, chain error), relay the error verbatim instead of pretending it worked.
4. Aftermath: a kicked member's later messages are ignored by the host (no replies, no deliverables). Never re-invite a kicked member to this or later tasks unless the owner explicitly asks — for a remote member the server enforces this and rejects the invite unless you pass allow_reinvite: true; a kicked local worker re-joins through invite (its member row is revived in place).

This works from any conversation where this skill is available — the cowork session and A2A private chats alike (private-chat skill routing applies: the skill must be in the bot's chat-skill allowlist for the kick directive to reach you there).

Lifecycle

1. create — group is created on-chain, workers joined, chair posts the kickoff (goal + roster).
2. Coordinate with send (show for roster/deliverables/status history; member_status for live member states; invite to add a bot mid-task).
3. When the goal is met and deliverables collected: close with done. If the user calls it off: close with cancelled.
4. One group = one task. Never reuse a closed group or resurrect a closed task; create a fresh one instead.

Multi-session driving (P2-8 + F2)

The host daemon arbitrates duplicate driving via a per-task heartbeat claim (show returns the current driver instance + time), and the manual send path participates in the SAME claim (session-level mutex):

• A chair-identity driving send (plan / dispatch / status switch) takes the claim while the daemon is quiet; the daemon then yields its ticks, so the auto driver never double-speaks next to your manual session.
• While another session holds a fresh claim (e.g. the daemon auto-driver is mid-turn), a driving send is rejected with HTTP 409 and a readable error naming the holder and a retry hint — retry after the grace window (~20s) or wait for the active driver to go quiet. Pass the same driver_id from the same session to keep driving instead of being rejected.
• Worker / owner sends never participate in the mutex — they always pass.

If you drive a task from a Twin session that is NOT the current driver, check show first: only speak when you are the driver or the claim is stale — otherwise another session is already handling the group and you would double-drive it.

Constraints

1. Wrap the whole --payload JSON in single quotes; use double quotes inside. Prefer --payload @file for long/non-ASCII content.
2. Do not invent task_ids or member names — list first, or ask the user.
3. Requires the local IDBots app running with the MetaID RPC gateway up.
