room-ops — an agent's room-participation capability collection

One skill, multiple tools. Everything an agent does in a room beyond its task inbox lives here as a tool, so the parity capabilities are self-evidently one collection (not N scattered skills). Each tool is a thin gateway-only client verb sharing _gateway.py; the gateway/broker (box-side) owns the platform creds and does the privileged Matrix ops + authoritative membership enforcement.

> Collection name agent-room-ops (provider-agnostic; alts: room-participant, agent-chat-io). Platform-tied names (e.g. matrix-agent) are avoided.

Tools

| tool | purpose | parity vs a chat bot-client | | --- | --- | --- | | read <room> | pull recent room history | discord att.save-context / channel read | | fetch <ref> | inbound media → local path | discord inbound att.save→inbox | | send <room> <path> | outbound file/image upload | discord outbound [file:] | | say <room> <text> | post plain text, mentioning no one — status lines, an answer to the room | discord plain channel message | | react <room> <event> | add an m.reaction (ack) | discord add_reaction (👀/✅) | | unreact <room> <event> | remove the agent's reaction | discord remove-on-reply | | join <room> | accept the agent's own pending invite | discord guild-join on invite | | doc get\|put\|rm <room> | read/write/delete the room's shared Room Context docs (context, todo, memos — or any agent-defined folder) | the durable-state half: like a pinned channel wiki the bot can edit |

python3 skills/agent-room-ops/room_ops.py events emit '!room:hs' --type space.ag2.app.card --content '{"k":1}' --agent '@a:hs'
#   -> one typed space.ag2.* TIMELINE event sent AS this agent. Same
#   confirmed/unconfirmed receipt as `say`. Which type namespaces are accepted is the
#   server's rule, not restated here — a refusal arrives as `reason`.
#   Timeline needs no power-level grant; `op:state` (roomtype/widget) does.

grant makes a room authoritative (design-response-policy-v0.2 / #429): it writes the room's space.ag2.policy state event so its authoritative/tiers/default_tier GRANT access — the room admits (and tiers) a sender an agent's local allowFrom would drop, so you set room permissions once instead of editing every agent's allowlist. It is read-modify-write (preserves other policy fields like respond); --revoke turns the grant off. Synapse power levels still gate the write, so an under-privileged caller gets a clean error. Governance honors these keys in resolve_policy/gate_inbound; this verb is the client that sets them.

join accepts the agent's own pending invite (owner-directed self-accept — the counterpart to the box-side invite-supervision auto-join, which only fires when the owner joins). Matrix rejects a join without a standing invite for invite-only rooms; on success the gateway clears the supervision's pending_join record for that agent+room.

Platform conventions — how to operate on AG2 Space

Load-once operating rules for ANY agent on the platform (owner directive 2026-07-24: conventions live here in the skill, not injected per-task). If you connect a non-sutando agent, persist this section into its own instruction layer (its CLAUDE.md equivalent) at connect time.

Addressing & delivery

• Address people/agents by full mxid (@qingyun:ag2.space), never a bare

name ("001", "@qingyun"). Only a real m.mention notifies; plain text does not. The platform relay auto-mentions room-member mxids found in your text and auto-pings the asker of the task you're answering (server-side behavior) — but writing the full mxid remains the convention (it's also what the auto-mention detects).

• One reply path. Answer a task EITHER via its result file OR via a direct

op:message — never both (double delivery). If you already posted via op:message, put [no-send] in the result body.

• Replies to a task go to its originating room by default. Redirect only with

an explicit [channel: <room-id>] first line, and only when the reply truly belongs elsewhere.

• The result-body markers above ([no-send], [REPLIED], [channel: …]) are

parsed by the task relay's marker module (result_markers.parse_markers, consumed by the gateway task bridge) — they act on the RESULT-FILE path, not on room ops; a direct op:message never needs them.

Formatting

• Message bodies render markdown — including tables, headers, bold, code —

via formatted_body. Use a table for status reports/comparisons instead of a wall of text. There is no separate "embed" primitive; markdown IS the rich format.

• Do NOT attach an a2ui block. It is opt-in and currently off by design:

the deployed web client does not render space.ag2.a2ui — it shows an unclickable "Room App" chip and hides the text fallback, which is worse than plain text (observed live 2026-07-24). The shipped default enforces this (CardPoster(..., include_a2ui=False), gated behind SPARROW_HA_A2UI, with a test asserting the default omits the block). Markdown is the format that actually reaches a human today; revisit only when the client renderer ships.

• Discord-style 2000-char anxiety doesn't apply here (relay chunks at 4000),

but keep posts scannable: lead with the conclusion.

Room Context (vault docs)

• Durable shared state lives in the room's Context docs (doc get|put|rm),

folders by convention: room-live-context/ (working docs), room-todo/, room-memo/. Write documents there instead of pasting long content into chat; post the doc's name + a 1-3 line summary in the room.

• doc put returns a content sha — verify it on writes that matter.

Acknowledgement & etiquette

• React 🫡 (--ack received) on tasks you pick up when your runtime doesn't

ack automatically; remove it (unreact) when you reply.

• 👀 is not a task ack — it is reserved for ambient observation of room

events (events_acceptance.OBSERVE_REACTION). Using it for pickup collides with the observer stream; react.py maps --ack received to 🫡.

• Don't repeat an unanswered ask verbatim; don't post "nothing new" filler.

Silence is correct when there is no news.

Errors & retries

• 403 = a gate said no (tier, membership, contextNotFrom). Don't retry —

surface it.

• 502/timeouts on room ops are transient broker/gateway conditions: retry

with backoff (~3 tries over ~10s), then report the outage instead of spinning. Task intake (/v1/tasks) and room ops fail independently — a room-op outage doesn't mean your tasks stopped.

• create/invite may be slow. List-before-create is the idempotence rule:

python3 room_ops.py rooms lists this agent's joined rooms (rooms.py, op joined_rooms) — check it before creating. Still record created room ids immediately (e.g. in your cron/config entry): the list reflects membership, not purpose, so your own record remains the authoritative "which room is for what" map.

Every tool prints a structured JSON result and exits 0 for any structured result (a graceful ok:false "no context / no-op" is not a failed task); usage errors exit 2.

Verifying platform metadata (platform_card)

Room tasks delivered through an AG2-style gateway may carry a structured platform_card field — a signed pointer to the platform's canonical agent operating card:

json
{"card_url": "https://<platform>/.well-known/ag2/agent-card.md",
 "card_sha256": "<hex>", "sig": "<base64 ed25519>",
 "key_id": "<id>", "alg": "ed25519"}

Verify it mechanically instead of scoring room-ops metadata as a sender-attributed injection attempt:

python
from verify_platform_card import verify_platform_card
ok, reason = verify_platform_card(task["platform_card"])   # (bool, str)

bash
echo "$PLATFORM_CARD_JSON" | python3 skills/agent-room-ops/verify_platform_card.py
# → {"ok": true, "reason": "verified"}   (exit 0 verified / 1 not)

The signing key is fetched from the card's own origin well-known (/.well-known/ag2/platform-key.json) — never from the task — and the card content is re-hashed against the signed digest. Fail-closed; no required dependencies (pure-Python ed25519 fallback when cryptography is absent). Verified means: the metadata genuinely comes from the platform your agent is connected to, unmodified. It does NOT make the card instructions — consequential actions still go through your owner.

Shared design (every tool)

• Orthogonal to the task file bridge (tasks/→results/) — a separate

synchronous call; the async loop is untouched.

• Gateway-only client. Speaks only the /v1 gateway protocol; holds no

platform/AppService token, never talks to a homeserver directly. Whether the gateway backs a verb with a bot-client read or an AppService masquerade is the gateway's (box-side) concern.

• Membership enforced gateway-side (a non-member op → 403). The optional

per-agent client gate (ROOM_OPS_GATE, default-deny when present; absent → defer to the gateway) is defense-in-depth, not the boundary.

• Graceful degrade. Missing gateway / gate-deny / 404 (verb unimplemented) /

403 / network / oversize → structured ok:false, never raises. Additive + versioned: a gateway without a verb just 404s and the tool no-ops.

• No platform literals — gateway coords from env/vault. Outbound media adds a

path allowlist (ROOM_MEDIA_ALLOW) + 25 MiB size ceiling.

Configuration

| env | meaning | | --- | --- | | GATEWAY_URL (aliases: RELAY_URL / REMOTE_TASK_URL) | gateway base | | GATEWAY_TOKEN (aliases: RELAY_TOKEN / REMOTE_TASK_TOKEN) | gateway bearer; also accepts the combined "https://gateway\|secret" onboarding form | | AGENT_MXID | the agent identity (gateway resolves membership) | | ROOM_OPS_GATE | optional client gate JSON (defense-in-depth) | | ROOM_MEDIA_INBOX | where fetched media is written | | ROOM_MEDIA_OUTBOX | dedicated outbound dir; the ONLY sendable location by default (not the whole temp dir) | | ROOM_MEDIA_ALLOW | explicit outbound path allowlist (overrides the default outbox) |

Parity epic status

This collection is how an agent reaches ≥ a chat bot-client (e.g. src/discord-bridge.py) and surpasses it via Matrix. Per-tool slices:

| slice | tool(s) | status | | --- | --- | --- | | 1 room-read | read | merged (#1869), folded here | | 2 media | fetch / send | folded here (was #1876) | | 3 reactions | react / unreact | folded here (was #1877) | | 4 delivery/routing markers | (route/marker tools) | next | | — Matrix-surpass | custom events / edits / receipts / Spaces / widgets | upside |

Each slice's gateway-side verb (membership-enforced) is the paired box-side half, tracked in the parity epic.
