Conversation
The harness service now serializes control commands per session, so the composer's client-side queue (drain loop, awaiting_turn latch, failed-head retry, QueuedPromptList) is redundant. Prompts post immediately; a failed POST surfaces as a toast. Sending is disabled until a just-created session's id lands, since there is no longer a pre-create queue.
Prompts and compacts sent while a turn runs are now held in an in-memory
per-session queue in the harness and dispatched one per turn end, instead
of being interleaved onto the ACP wire. The queue is listable, and entries
are editable and removable until they dispatch.
Backend:
- AgentActionId is a bare uuid v7 (legacy agent_session:-prefixed ids in
stored logs still parse)
- SessionMachine tracks the in-flight turn and emits TurnEnded on its
response; stop no longer voids pending actions (it cancels only the
running turn - the queue keeps draining)
- Harness gates dispatch on a per-session busy mark, serialized on the
existing per-session command worker; compose + chip announcement move
to dispatch time, so queued entries hold raw, editable text
- POST /control returns {actionId, status: sent|queued} and now needs
Edit access (was Owner); new GET/PUT/DELETE /agent-sessions/{id}/queue
- Queue snapshots publish over the connection gateway as
agent_session_queue on every mutation
Clients:
- Web composer renders the queue (next-to-dispatch adjacent to the input),
rows are always-editable Lexical surfaces autosaving as you type,
Up-arrow walks from the composer into the queue; no polling and no
client-side queue state - the gateway is the only writer after baseline
- SDK: session.queue() returns QueuedAction handles with edit()/remove();
control() returns the new response shape
An event is always the full queue, so events need no ordering among themselves; a baseline response identifies itself by the session it was fetched for. The socketAuthoritative latch is the whole reconciliation.
No backwards-compat shim: from_request_id parses bare uuids only. Frames logged in the prefixed era refold with request_id: None, which nothing reads - correlation only ever happens live, against an id the client was just handed.
- Cursor staff gate now covers EditQueued/RemoveQueued (queue mutations carry the acting user and are judged like delivery) - queue routes enforce ensure_harness_serves_session like control - deleting a session drops its queue and busy mark and publishes the emptied snapshot - the chip announces at most once per entry: dispatch marks the claimed entry announced, so a requeued failure retries without a second chip - edits refuse blank prompts (422; schema minLength 1) - composer only claims Up/leave-at-start keys while a queue row exists - session switch resets in-flight prompt count
…Cursor The execute() staff check was keyed on AgentKind::Cursor, so Cursor sessions required a macro.com opener/actor while Daytona (sandboxed coder) sessions had no gate at all. Swap it to AgentKind::SandboxedCoder so Daytona is staff-only and Cursor is unrestricted.
An outbound adapter (connection_gateway_realtime) was importing it from inbound::axum_router, violating the hexagonal-architecture rule that outbound adapters depend on the domain, not on each other. The type is domain-owned (both the queue GET response and the realtime queue snapshot serialize it byte-identically); axum_router re-exports it so existing importers are unaffected.
The longer domain-placement rationale leaked into the generated SDK and web OpenAPI specs, which failed CI. Keep the public schema description unchanged and leave the placement note as a regular comment. Co-authored-by: Wolf Mermelstein <wolf@404wolf.com>
Dispatch composed after posting the chip, so a lexical failure still announced a prompt that never reached the agent. Compose first, announce from the raw text, then deliver the composed action. Coder-session resume tests also hung: the Daytona staff gate rejected non-staff actors, so resume never ran. Send those fixtures as staff. Co-authored-by: Wolf Mermelstein <wolf@404wolf.com>
edit_prompt kept the original actor, so a session editor could rewrite waiting text that later announced and logged as someone else. The PUT handler already passed the editor; persist that on the entry. Co-authored-by: Wolf Mermelstein <wolf@404wolf.com>
QueuedAction had no per-item GET to lazily refetch from (only the queue snapshot), so it doesn't fit MacroEntity's fetch-by-id shape. Match CrmComment's pattern instead: a private constructor behind a .from() factory, get accessors over a mutable record, and edit() applying the change locally (the endpoint answers 204, so there's no response body to reread) and returning this for chaining instead of void.
The session machine answered every `session/request_permission` with the
broadest allow option. That is fine inside sandboxes we own, but a macrod
harness is somebody's own machine.
- `PermissionPolicy { AutoAccept, Prompt }` resolved per attach from a new
`PermissionPolicySource` port. Default by runtime kind: cursor, in-memory
and the sandboxed coder auto-accept; macrod (`External`) prompts. A
persona's `agent_configs.auto_accept_permissions` (nullable; NULL = kind
default) overrides.
- `AgentAction::RespondToPermission` rides the existing `/control` pipe as a
non-turn-occupying action; the machine validates it against the request it
holds open and sends the ACP response with the agent's own id. Stop, turn
end and death cancel open requests. A harness principal cannot answer.
- Fold exposes `requestId` on permission parts; the transcript renders the
agent's options as buttons and the composer shows a banner for the running
turn's pending prompts.
- Agents dialog gains an "Auto-accept permission requests" toggle pre-filled
from the chosen runtime, with a warning when on for macrod.

📝 SummarySummary by CodeRabbit
WalkthroughThis change adds server-authoritative agent-session queues with FIFO dispatch, editing, removal, capacity limits, and realtime snapshots. Control responses now report whether actions were sent or queued. Permission requests can be auto-accepted or answered through the composer and SDK. Agent request IDs and action IDs receive updated protocol representations. Runtime permission policies are persisted per agent and applied during session attachment. The web composer adds queue editing, focus navigation, and permission controls. Tests and OpenAPI specifications cover the new behavior. Merge Risk: 🟡 Moderate · up to Permission requests can be auto-approved contrary to an agent owner's setting, and some numeric request IDs cannot be answered from the web client. Queue state can also become stale after reconnects or failed edits, so the material permission and synchronization issues should be resolved before merge. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Stale permissions stay answerable
High Severity
answerable treats every pending permission as live whenever the session is working(), including parts from an earlier turn or a previous connection. After reconnect, request ids restart, so a click on an old card can answer a new request that reused the same id.

Turn-end leaves permissions pending
Medium Severity
resolve_permission finds the part only through the open turn. The machine logs the prompt result first, which closes that turn, and only then sends Cancelled for leftover requests, so those parts stay pending in the transcript.

Inline comments:
In `@apps/web/src/features/block-agent/context/create-composer-controller.ts`:
- Line 125: Update the prompt completion flow in the composer controller so each
POST captures the current session generation, and only decrement inflightPrompts
when that generation still matches the active session. Preserve the existing
non-negative counter behavior and ensure stale prompts cannot change sending or
busy state for a newer session.
- Around line 120-121: Route all service-client network calls through TanStack
Query mutations or adapters in the queries package: update
create-composer-controller.ts at lines 120-121, 136-137, 158-159, and 176-177 to
use query-layer operations for prompts, model changes, stop controls, and
permission responses; update interceptor.ts at lines 44-45 to obtain queue data
through the query-layer abstraction instead of calling real.queue() directly.
In `@apps/web/src/features/block-agent/context/create-queue-controller.ts`:
- Line 21: Update createQueueController to stop calling
agentHarnessServiceClient directly for baseline, edit, and remove operations.
Add corresponding TanStack Query-backed query and mutation APIs under the
queries package, then use those APIs from createQueueController so all
service-client network calls are routed through that layer.
- Around line 103-104: Update the queue controller’s baseline flow to track a
monotonically increasing socket-session generation: increment it when a session
changes or WebsocketEvent.Open starts a new session, capture the current
generation in baseline(), and ignore the response if the generation changed
before it settles. Add a reconnect test where the first baseline is delayed and
verify the older response cannot overwrite the newer session’s baseline.
- Around line 117-145: Update the edit and remove handlers in the queue
controller to remove the matching local queued entry when their mutation result
is an error containing NOT_FOUND, while preserving the existing toast behavior
for other failures. Reuse the controller’s existing queue-state update mechanism
and match by actionId so stale rows are retired even when the dispatch snapshot
is missed.
In `@apps/web/src/features/block-agent/ui/QueuedPrompts.tsx`:
- Line 251: Update the compact queue entry styling in CompactBody to add a
visible focus indicator using focus-visible ring utilities, while removing the
conflicting outline-none class so programmatic keyboard focus from AgentInput
remains clearly indicated.
In `@apps/web/src/features/settings/Agents.tsx`:
- Around line 819-823: Update the ToggleSwitch in SettingsRow to provide an
accessible name for the auto-accept permissions control, using its label or an
appropriate aria-label/aria-labelledby association while preserving the existing
checked state and onChange behavior.
In `@apps/web/src/lib/service-clients/service-agent-harness/openapi.json`:
- Around line 909-911: Update the requestId schema to reference the shared
RequestId contract, restricting values to strings, integer numbers, or null
instead of unrestricted serde_json::Value; then regenerate the web OpenAPI
document and SDK specification from the Rust schema.
In `@crates/agent_fold/src/domain/model.rs`:
- Line 50: Update AgentRequestId::Number and the
createComposerController/on_permission_answer request flow to use a tagged
lossless representation for numeric permission IDs, ensuring values above
JavaScript’s Number.MAX_SAFE_INTEGER are transmitted exactly and reconstructed
as RequestId::Number for outstanding_permissions lookup. Add a regression case
covering an ID above Number.MAX_SAFE_INTEGER.
In `@crates/agent_harness/src/domain/service.rs`:
- Around line 1163-1176: The permission_policy_for method currently falls back
to AgentKind’s default, which can weaken managed agents’ persisted auto-accept
setting after a lookup failure. Replace that fallback with
PermissionPolicy::Prompt, or propagate the failure to abort attachment, while
preserving the existing warning context.
In `@crates/agent_harness/src/domain/service/test.rs`:
- Around line 1282-1292: Synchronize the test after
agent.sends_raw(permission_request("perm-1")) and before service.control_event
so it observes the permission request being recorded by
SessionRuntime/SessionMachine, ensuring outstanding_permissions contains perm-1
before submitting the answer.
In `@crates/agent_session/src/domain/connection.rs`:
- Around line 303-304: Update RuntimeConnection::bind to require an explicit
PermissionPolicy instead of constructing PermissionPolicy::default() internally,
and propagate the caller-selected policy through the external reattach path into
attach_session. Preserve prompting behavior by preventing callers from relying
on the AutoAccept default.
In `@crates/agent_session/src/inbound/axum_router.rs`:
- Line 657: Update the RespondToPermission handler’s access extractor to require
OwnerAccessLevel while retaining EditAccessLevel for prompt controls, ensuring
channel editors cannot approve pending tool actions.

Keep prompt completion state scoped to its originating session.
After a session switch resets inflightPrompts, an old prompt can settle after a new session starts a prompt. Line 125 then decrements the new session's count. sending and busy can become false while the new prompt POST is still pending.
Capture a session generation with each POST. Update the counter only when that generation is still current.

Discard baselines from an earlier socket session.
A prior GET /queue can remain in flight when the socket reopens. This reset allows that older response to update queued after the new socket session has already loaded a newer baseline, if no queue event arrives. The queue can then show stale entries until another queue mutation or reconnect.
Track a monotonically increasing socket-session generation. Capture it in baseline() and discard the response if the generation changed before it settles. Add a delayed-first-baseline reconnect test.
Proposed fix
let socketAuthoritative = false;
+let socketSession = 0;
const baseline = async () => {
+ const baselineSession = socketSession;
const sessionId = untrack(options.sessionId);
if (!sessionId) return;
const result = await agentHarnessServiceClient.queue(sessionId).catch(() => undefined);
- if (socketAuthoritative || sessionId !== untrack(options.sessionId)) return;

Remove the local queue entry on NOT_FOUND. SessionQueues removes claimed entries before dispatch, while queue publication is best-effort. The controller currently leaves queued unchanged. If the snapshot is missed before the folded message arrives, QueuedPrompts can keep rendering the stale row and controls until a later event. Remove the matching local entry when either mutation returns NOT_FOUND.

MDN JavaScript Number.MAX_SAFE_INTEGER exact integer precision JSON.parse
💡 Result:
In JavaScript, Number.MAX_SAFE_INTEGER is a static constant representing the largest integer (2^53 - 1, or 9,007,199,254,740,991) that can be represented exactly as an IEEE 754 double-precision floating-point number [1][2][3]. When using JSON.parse, any integer value exceeding this threshold (or falling below the negative equivalent) will silently lose precision during the parsing process [4][5][6]. Because the standard JavaScript JSON parser automatically converts all JSON numbers into the native number type (an IEEE 754 64-bit float), integers outside the safe range are rounded to the nearest representable double-precision value [7][4][5]. This happens without throwing an error, leading to potentially incorrect data in applications, such as with large database IDs or 64-bit integers [4][5][8]. To handle integers larger than Number.MAX_SAFE_INTEGER without losing precision, consider these common approaches: 1. Send as Strings: The most robust, interoperable solution is to ensure large numbers are serialized as strings in the JSON source (e.g., "12345678901234567890") [4][5][6]. Strings are parsed losslessly, and they can be converted to BigInt in JavaScript if arithmetic is required [9][5]. 2. Use a Custom Parser: If you cannot control the JSON source and must handle bare numbers, use a third-party, BigInt-aware JSON parser (such as json-bigint or lossless-json) [7][4][10][5]. These libraries can parse large numeric literals directly into BigInts, bypassing the precision limitations of the standard number type [7][5]. 3. Reviver Function: You can attempt to use the reviver parameter in JSON.parse, but note that if the source JSON provides a number (not a string), the precision loss has often already occurred by the time the reviver function is called [9][7][6]. To use this approach effectively, the source must typically provide the value as a string [9]. Since BigInts cannot be serialized by default using JSON.stringify, ensure you convert them back to strings before sending them in JSON [5][6].

Preserve numeric permission IDs without JavaScript rounding.
AgentRequestId::Number stores i64 but exports as a TypeScript number. If an agent sends an ID above Number.MAX_SAFE_INTEGER, the browser can round it before createComposerController posts it. on_permission_answer then cannot find the exact ID in outstanding_permissions, returns PermissionRequestNotFound, and leaves the permission pending.
Use a tagged, lossless ID representation that reconstructs RequestId::Number on the server. Add a regression case above Number.MAX_SAFE_INTEGER.

Wait for the permission request to be recorded before answering. SessionRuntime selects the command and inbound channels independently. If the answer reaches SessionMachine::on_permission_answer first, no outstanding_permissions entry exists, so it returns PermissionRequestNotFound and expect panics. Add a synchronization point that observes request processing before calling control_event.

Security Misconfiguration (CWE-1188): Insecure Default Initialization of Resource
Reachability: Internal · Exploitability: Difficult
Make PermissionPolicy explicit in RuntimeConnection::bind.
The current external reattach path overrides the AutoAccept default. Any future caller can still pass the defaulted attachment directly to attach_session and bypass prompting.

In `@crates/agent_session/src/domain/connection.rs` around lines 303 - 304, Update
RuntimeConnection::bind to require an explicit PermissionPolicy instead of
constructing PermissionPolicy::default() internally, and propagate the
caller-selected policy through the external reattach path into attach_session.
Preserve prompting behavior by preventing callers from relying on the AutoAccept
default.

Authorization Bypass (CWE-269): Improper Privilege Management
Reachability: External · Exploitability: Moderate
Require owner authorization for RespondToPermission.
PermissionPolicy::Prompt forwards the selected permission option to the runtime. The shared handler only requires EditAccessLevel, so channel editors can approve pending tool actions. Keep prompt controls at Edit, but require OwnerAccessLevel for permission responses or split them into a separate endpoint.

Why
SessionMachine::respond_to_permission_requestanswered every ACPsession/request_permissionwith the broadest allow option, with nobody in the loop. Inside sandboxes we own that is harmless; on a macrod harness it is a bot approving its own tool calls on someone's real machine.What
Policy, resolved per attach
PermissionPolicy { AutoAccept, Prompt }(agent_session), carried onRuntimeAttachmentlikemcp_servers.AgentKind: cursor / in-memory / sandboxed coder → auto-accept; macrod (External) → prompt. A persona's new nullableagent_configs.auto_accept_permissionsoverrides;NULLmeans "kind default". Resolved through a newPermissionPolicySourceport (PgPermissionPolicySourcein the service), falling back to the kind default on a lookup error so a DB blip never blocks an attach.Answering
AgentAction::RespondToPermission { requestId, answer }rides the existingPOST /agent-sessions/{id}/controlpipe as a non-turn-occupying action. The machine short-circuits it inon_command, validates it against the request it holds open (unknown id → 409, unoffered option → 422), and sends the ACP response echoing the agent's own id — kept asRequestId(string or number), since7does not answer"7".session/cancel, per ACP), turn end, and death (when the transport is still up) resolve open requestsCancelled.actor: None) may not answer — that would be the runtime approving itself. An answer to a disconnected session returnsDisconnectedwithout resuming a sandbox.Fold + frontend
MessagePart::PermissioncarriesrequestId(specta-exported asstring | number).PermissionPartrenders the agent's options as buttons while the request is open in a live session;AgentComposershows a banner with the same options for the running turn's pending prompts, so a blocked turn is never buried.nullso a future default change flows through.docs/AGENT_GUIDE/ai-chat.mddocuments both.Testing
cargo test -p agent_runtime_protocol -p agent_session -p agent_harness -p agent_fold -p bots -p agent_trigger— all green; new machine tests cover the prompt path, answers (valid / unknown / unoffered / before-live / dead), numeric ids, and cancellation on stop, turn end, and abandon vs. dead transport. Harness tests cover per-kind policy, the harness-principal refusal, and the no-resume path. Fold snapshots updated forrequestId.cargo fmt,just clippy,just prepare_db.apps/web:bun run check, biome, vitest (new controller tests for answering).Not in this PR: notifying the channel thread when a trigger-opened session is blocked on a prompt (
SessionAnnouncerfast-follow); a server-side timeout for unanswered prompts (the sans-IO machine has no clock, and a silent auto-cancel is worse than a visible pending prompt);packages/sdkclient regeneration (specs synced,openapi-tsmissing locally; no new endpoints,just coveragepasses).Note
Medium Risk
Changes how sessions accept prompts and how tool permissions are answered on live runtimes; macrod auto-accept remains opt-in with UI warning but misconfiguration could approve commands without prompts.
Overview
Moves mid-turn prompt ordering to the harness service and reshapes the block composer around that. The client no longer drains a local queue or waits for the fold before sending the next prompt—
sendposts immediately, failures toast instead of retry rows, andQueuedPrompts(edit/remove, keyboard focus with the input) reflects the server queue synced viaGET …/queue,agent_session_queuewebsocket snapshots, and dedupe against foldedrequestIds. Control acks are now{ actionId, status: sent | queued }.Adds interactive ACP permission handling in the UI: fold permission parts expose
requestId, transcriptPermissionPartandAgentComposerrenderPermissionOptionsand postrespondToPermissionon the existing control endpoint while a turn is live.Persists
agent_configs.auto_accept_permissions(sqlx insert/update/list) and wires an Agents settings toggle (runtime-aware default, macrod warning). Agent create/update APIs pass through the nullable override.agent_foldstamps permissionrequestId, treatsRespondToPermissionas non-control, and real-fixture snapshots pick up uuid-shaped userrequestIds on prompts/controls.Reviewed by Cursor Bugbot for commit a40985d.
