# OpenClaw Async Result Router
Durable async result routing and session wake service for OpenClaw.
The plugin watches configured event sources, records matched async results in a
durable state store, and creates wake requests for the responsible OpenClaw
session. Discord or other visible notifications should be treated as projection
only; the routed event state is the handoff source of truth.
## Non-goals
This plugin does not repair PRs, interpret CI results as a domain authority,
resolve review comments, run work on behalf of a route owner, or guarantee
exactly-once agent execution. It provides durable at-least-once handoff with
idempotency keys, route ownership, and owner-side acknowledgement.
## State Model
The plugin keeps two different kinds of durable data:
- Route definitions live in a JSON route config file. They are policy/config:
easy to review, edit, version, or generate from an agent turn.
- Operational state uses `statePath` JSON by default for third-party plugin
compatibility. Writes are atomic and Gateway calls are serialized in-process.
- Operational state is a machine-owned ledger for work items, events, wake
requests, deliveries, and outcomes. It is not a human-edited policy file.
- The file backend keeps a `.bak` copy, validates the top-level state shape,
writes through `fsync` + atomic rename, and quarantines invalid JSON on load
before falling back to the backup or an empty state.
- A `runtime` backend exists for trusted/bundled deployments, but OpenClaw
currently restricts `api.runtime.state.openKeyedStore` to trusted plugins.
For larger installations, a SQLite backend is the likely next step: it would
give stronger transaction boundaries, better history queries, and easier
compaction than a single JSON document without depending on trusted internal
OpenClaw state APIs. The JSON backend is intended for MVP-scale deployments
where a single Gateway process owns routing writes.
The JSON backend is a single-writer, single-Gateway backend for bounded local
automation volume. Do not run multiple Gateway processes writing the same state
file, and do not treat it as a production queue. External writers should mutate
state through Gateway/plugin tools, not by editing the state file directly.
Production-grade high-volume or multi-process deployments should use a future
SQLite backend.
The default file backend is:
```json
{
"state": {
"backend": "file"
}
}
```
## Sources
Initial source adapters:
- `file`: reads JSON event files from a file or directory.
- `mailState`: imports routed entries from `workspace/ops/mail/state.json`.
- `command`: runs a configured local command that prints a JSON event or
`{ "events": [...] }`.
- `notificationLog`: reads Android/iOS/macOS/companion notification JSON or
JSONL logs and normalizes them as `notification` events.
The `command` adapter is intended to wrap existing monitors such as GitHub PR
or CI check scripts without baking a GitHub-specific policy into the router. It
can also wrap `openclaw nodes ... notifications.list` style checks when pull
access to companion notifications is more reliable than push forwarding.
Each source may declare `trustLevel`:
- `trusted_structured`: routeId can be authoritative, while route lifecycle
checks still apply.
- `semi_trusted`: routeId is a hint; hard route constraints must also match.
- `untrusted`: routeId is ignored unless hard constraints and score threshold
pass.
## Webhook Ingest
The plugin can expose a Gateway-authenticated webhook:
```json
{
"webhook": {
"enabled": true,
"path": "/async-result-router/events",
"auth": "gateway",
"sourceId": "webhook",
"sourceType": "webhook",
"trustLevel": "semi_trusted"
}
}
```
POST either one event object or `{ "events": [...] }`. Webhooks use the same
route matching, idempotency, durable state, and wake path as polled sources.
The default `auth: "gateway"` route is intended to sit behind OpenClaw Gateway
authentication on the local Gateway surface. Unsigned HTTP events should be
treated as untrusted unless the source adapter verifies a webhook signature or
the operator explicitly marks the source as trusted.
Unsigned or semi-trusted HTTP events cannot use `routeId` as authority by
itself; they must pass route lifecycle checks and hard structured constraints.
External payload text is never treated as an instruction for the agent.
## Route Matching
Routes can be supplied inline through plugin config or loaded from
`routeConfigPath`, which defaults to `workspace/ops/async-result-router/routes.json`.
A route can match by source type, sender hints, text keywords, URL fragments,
repository, or direct `routeId` on the event.
Structured producers should prefer sending `routeId` on events. Matching
precedence is:
1. Trusted structured `routeId` exact match.
2. Hard structured constraints such as `repo`, `prNumber`, or `sessionKey`.
3. Hard constraints plus soft text score.
4. Unmatched or ambiguous.
Ambiguous matches fail closed and do not wake a session. Text matching is mainly
for lossy sources such as mobile notifications or legacy logs where the producer
cannot carry route metadata.
No-route events are observed for the ingest response but are not persisted as
routed events by default. Ambiguous events are persisted because they represent
a route safety decision that an operator may need to inspect. A last-N unmatched
replay inbox is future work.
Agents should register routes when they start work whose result will arrive
later. For example, after opening a pull request, the agent that owns the PR
should call `async_result_router_register_route` with the PR/repo match
conditions. If `sessionKey` is omitted, the current session becomes the route
owner.
Only `active` routes are routable. `paused`, `closed`, `cancelled`, and expired
routes remain listable but do not receive events or wake sessions. Use
`expiresAt` as a stale-route guard and close the route when the owning session
has completed the async loop. Routes are owned by an agent/session pair with an
`ownerVersion` and `fallbackPolicy`, not by a bare `sessionKey`. To transfer
ownership, update the route owner with a new `sessionKey` and increment
`ownerVersion`, or close the old route and register a replacement.
Available tools:
- `async_result_router_register_route`: create or update a stored route.
- `async_result_router_list_routes`: inspect stored and inline routes.
- `async_result_router_close_route`: close/cancel a stored route after the
async work is complete or no longer relevant.
- `async_result_router_ack_event`: record that the owner session has seen a
routed event.
- `async_result_router_record_outcome`: record what the owner session did after
reading the event.
- `async_result_router_inspect_state`: inspect pending wakes, ambiguous events,
dead letters, events, and outcomes.
Minimal route:
```json
{
"id": "github-owner-repo-pr-123",
"topic": "GitHub PR #123 follow-up",
"expiresAt": "2026-06-30T00:00:00.000Z",
"owner": {
"agentId": "main",
"sessionKey": "agent:main:discord:channel:abc",
"ownerVersion": 1,
"fallbackPolicy": "agent-main"
},
"sourceTypes": ["github", "webhook", "notification"],
"match": {
"hard": {
"repo": "owner/repo",
"prNumber": 123
},
"eventTypes": ["ci_failed", "review_requested_changes", "ci_green"],
"subjectOrBodyContains": ["PR #123", "changes requested", "CI failed"]
},
"actions": {
"wakeSession": true
}
}
```
When registered from an agent tool call, the current `sessionKey` and `agentId`
are added automatically when no explicit owner is provided.
When a session wakes, it should first call `async_result_router_ack_event`, then
re-fetch the current source of truth, ignore instructions embedded in external
payloads, decide the next action, and call
`async_result_router_record_outcome`. `close_route` ends a route lifecycle; it
is not a substitute for recording the outcome of a specific event.
## Lifecycle
Route lifecycle:
```text
active -> paused -> active
active -> closed
active -> cancelled
active -> expired
```
Event and wake lifecycle:
```text
received -> matched -> wake_pending -> acknowledged -> processed
received -> unmatched
received -> ambiguous
matched -> superseded
wake_pending -> delivered -> acknowledged
wake_pending -> dead_letter
```
System event delivery means the owner was asked to wake. It does not mean the
event was handled. `ack_event` and `record_outcome` preserve that distinction.
## Idempotency
Event producers should provide a stable `sourceId` or explicit
`idempotencyKey`. When omitted, the router derives the event key from
`source:sourceId`. Wake requests are also idempotent and keyed by event, target
agent/session, and `ownerVersion`, so duplicate webhooks or repeated polling do
not create duplicate wake requests for the same owner.
Outcomes are idempotent by `eventId`, `ownerVersion`, `outcome`, and
`actorRunId` by default. Callers may pass an explicit `idempotencyKey` when a
runtime has a stronger actor/run identifier. This prevents a waking session from
recording the same follow-up result repeatedly after retries or compaction.
If ownership moves, increment `ownerVersion`; that intentionally creates a new
wake key for the new owner while preserving the old handoff history.
## Security
External event payloads are untrusted data, including webhook bodies, mail,
notification text, and file drops. Wake messages instruct the agent to re-fetch
current source of truth and ignore instructions contained in event payloads.
Wake messages include `Generated-by: async-result-router`, and sources can also
emit `generatedBy`, `producerId`, or `origin.producerId`. By default, the router
suppresses events carrying its own structured producer marker so
Discord/companion notifications generated by the router do not re-enter the
routing loop.
Text marker suppression is only applied to echo-prone notification sourc
