# 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 |

```bash
python3 skills/agent-room-ops/room_ops.py read   '!room:hs' --limit 20 --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py fetch  'mxc://hs/abc' --room '!room:hs' --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py send   '!room:hs' /tmp/pic.png --caption 'fig 1' --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py react  '!room:hs' '$evt' --ack received --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py unreact '!room:hs' '$evt' --ack received --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py say    '!room:hs' 'deploy finished, 3 green' --agent '@a:hs'
#   -> {"ok":true,"state":"confirmed|unconfirmed","event_id":...}. `confirmed` means an
#   event id came back. `unconfirmed` is a 200 with no proof: the send probably landed, so do
#   NOT re-send blindly, but do not drop a fallback/result path on it either.
#   Use `mention` instead when a specific agent must be triggered; `say` never pings.
python3 skills/agent-room-ops/room_ops.py join   '!room:hs' --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py doc get '!room:hs' --folder room-todo --name TODO.md --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py doc put '!room:hs' --folder room-memo --name note.md --file /tmp/note.md --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py doc rm  '!room:hs' --folder room-memo --name note.md --agent '@a:hs'
python3 skills/agent-room-ops/room_ops.py grant '!room:hs' --tier '@u:hs=owner' --default-tier guest --agent '@a:hs'
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 `404`s 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.

## Layout

```
agent-room-ops/
  _gateway.py        shared: gateway coords + per-agent gate + http + degrade
  read.py          read_room()
  media.py         fetch_media() / send_media()
  react.py         react() / unreact()
  room_ops.py      unified CLI dispatcher
  test_room_ops.py 39 tests, no network
```

## 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.
