From e496cadd23b1c862b314d04c0a6057c2b6b9672f Mon Sep 17 00:00:00 2001 From: David Hagerty Date: Tue, 10 Feb 2026 21:04:31 -0500 Subject: [PATCH] feat: implement V2 Phase 2 (orchestrator) and Phase 3 (daemon HTTP API) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 2 adds the multi-agent orchestrator with work packages, worktree isolation, message bus, and agent tools. Phase 3 adds a full HTTP daemon with axum — project/goal/node/edge/task/decision/session/search/import-export API endpoints, WebSocket event streaming, CLI daemon detection with thin client routing, and static asset serving behind a bundle-ui feature flag. 42 new daemon tests across 5 test files. All 300+ tests pass.

This phase implements a flat `src/message.rs` file because the Envelope type (wrapping messages with sender/recipient/timestamp metadata) adds complexity without clear benefit at this stage — the sender is already embedded in Worker→Orchestrator variants via `agent_id`, and the MessageBus trait handles routing. If the Envelope type becomes needed (e.g., for message logging, replay, or ordered delivery), it can be extracted into a `src/message/` directory in a future phase without breaking the public API (`MessageBus` trait and `WorkerMessage` enum remain the same). + +**Implementation:** + +`src/message.rs` contains three main items: + +**1.

Reasonable defaults: broadcast_capacity=64, agent_channel_capacity=32. +- `subscribe()` — creates a new mpsc channel pair, stores the sender in agent_channels, spawns a background tokio task that reads from `broadcast_tx.subscribe()` and forwards to the mpsc sender (so the consumer gets one unified receiver). Returns the mpsc receiver. +- `send()` — looks up the agent's mpsc sender and sends the message. Returns error if agent not subscribed (log warning but don't panic — fire-and-forget semantics). +- `broadcast()` — sends on the broadcast channel. Ignores `SendError` (no subscribers) gracefully. + +The subscribe forwarding task should handle `broadcast::error::RecvError::Lagged` by logging a warning and continuing (not crashing). When the mpsc receiver is dropped, the forwarding task should detect the send failure and exit cleanly. + +Also implement a `remove_subscriber(&self, agent_id: &AgentId)` method to clean up the agent_channels entry when a worker completes.

Verified implicitly by AC1.1's construction tests, which use named fields matching the spec (e.g., `ProgressReport { agent_id, turn, summary }`). | +| P2a.AC1.3 | integration | `tests/message_test.rs` | Clone a WorkerMessage variant, format it with `Debug`.

If any method is missing, compilation fails. All subsequent tests exercise these methods. | +| P2a.AC2.2 | integration | `tests/message_test.rs` | Create TokioMessageBus, subscribe agent "a1", send a targeted message to "a1", receive it on the subscriber's receiver. Assert the received message matches. | +| P2a.AC2.3 | integration | `tests/message_test.rs` | Subscribe two agents, broadcast a message. Both receivers get the message. | +| P2a.AC2.4 | integration | `tests/message_test.rs` | `subscribe()` returns a receiver that gets both targeted messages (via `send`) and broadcast messages.

Verified by the behavior tests (AC2.2, AC2.3, AC3.3) which demonstrate that broadcast reaches all subscribers while targeted delivery reaches only one. | +| P2a.AC3.2 | integration | `tests/message_test.rs` | Subscribe 3 agents, broadcast a message. All 3 receive it. | +| P2a.AC3.3 | integration | `tests/message_test.rs` | Subscribe two agents "a1" and "a2". Send targeted message to "a1". Verify "a1" receives it and "a2" does not (use `tokio::time::timeout` to confirm "a2" gets nothing within 100ms). | +| P2a.AC3.4 | integration | `tests/message_test.rs` | Broadcast a message before any subscription. Then subscribe an agent. Use `tokio::time::timeout` to confirm the subscriber does not receive the earlier message (fire-and-forget semantics). | +| P2a.AC3.5 | integration | `tests/message_test.rs` | Subscribe an agent, drop the receiver. Broadcast a message. Bus does not panic.

Format with Debug to verify they exist. | +| P2c.AC2.2 | unit | `tests/orchestrator_test.rs` | Verify state transitions follow the defined state machine graph. Create orchestrator, check initial state is Startup. Manually set state to each valid transition to confirm the enum works. Full run-loop transition testing deferred to Phase 2d integration tests. | + +### P2c.AC3: Orchestrator struct + +| AC | Type | Test File | Description | +|----|------|-----------|-------------| +| P2c.AC3.1 | integration | `tests/orchestrator_test.rs` | Create Orchestrator with mock GraphStore and mock MessageBus.

Run scheduling. Verify the orchestrator queries and discovers them for work package creation. | +| P2d.AC3.2 | integration | `tests/orchestrator_test.rs` | Create multiple Ready tasks with overlapping file scopes. Scheduling groups them into work packages using `group_tasks_into_packages`. | +| P2d.AC3.3 | integration | `tests/orchestrator_test.rs` | Set `max_concurrent_workers=1`. Create 2 Ready tasks. Scheduling spawns only 1 worker. The second is deferred to the next scheduling pass. | +| P2d.AC3.4 | integration | `tests/orchestrator_test.rs` | No ready tasks remain and no workers are active.

Verify by string containment on all 5 profiles. | +| P2d.AC7.2 | unit | `tests/orchestrator_test.rs` | Profile-specific rules: planner's rules contain "independently"; coder's contain "declared scope"; reviewer's contain "Do not modify"; tester's contain "behavior"; researcher's contain "findings". Verify by string containment. | + +### P2d.AC8: Check-in interval support + +| AC | Type | Test File | Description | +|----|------|-----------|-------------| +| P2d.AC8.1 | integration | `tests/orchestrator_test.rs` | Create AgentRuntime with `message_bus` and `check_in_interval=2`.

In this phase, `run` always executes locally with an in-process orchestrator. The daemon provides monitoring (WebSocket events, API status queries) but does not run orchestration itself. Future work could add `POST /api/projects/:id/goals` triggering daemon-managed orchestration, with `run` posting the goal to the daemon when one is detected and streaming progress via WebSocket. This is deferred — Phase 3 establishes the daemon infrastructure, not daemon-managed orchestration. + +For the initial implementation, each command's daemon path calls the DaemonClient method and formats the output identically to the local path. This is somewhat verbose but keeps the local fallback working without changes. + +**Alternative (refactored) approach:** Extract the display logic into shared functions that accept data (not how it was fetched). This reduces duplication.

These functions only use `GraphStore` trait methods, so this is a type-signature-only change — except `import_goal` which uses a `SqliteGraphStore`-specific helper (`import_nodes_and_edges`) that needs to be promoted to the trait or reimplemented using `create_node`/`add_edge`. + +### Already done (verified) +7. **`SessionStore::get_session(id)` method**: Already exists in `src/graph/session.rs`. +8. **`SessionStore::list_sessions(goal_id)` method**: Already exists. diff --git a/src/agent/builtin_profiles.rs b/src/agent/builtin_profiles.rs index 7939929..af65d74 100644 --- a/src/agent/builtin_profiles.rs +++ b/src/agent/builtin_profiles.rs @@ -7,7 +7,14 @@ pub fn planner() -> AgentProfile { name: "planner".to_string(), extends: None, role: "Task breakdown specialist".to_string(), - system_prompt: "You are a task breakdown specialist.
