Make Compound Engineering stage launch gating opt-out so registered stages like debug remain launchable by default. - Replace enabledStages settings schema with disabledStages defaults and docs. - Derive launchable stages from the live registry minus explicit disabled opt-outs. - Update orchestrator gating, exports, tests, and plugin docs for the new setting. - Add a patch changeset for the Compound Engineering plugin behavior fix.

# Compound Engineering Plugin
|
|
|
|
A dedicated dashboard surface for the compound-engineering (CE) workflow — an
|
|
artifact hub, interactive `ce-*` skill sessions, a work→board bridge, and
|
|
event-driven bidirectional sync. It runs alongside Fusion's native pipeline.
|
|
|
|
## Install
|
|
|
|
1. Open **Settings → Plugins → Fusion Plugins**.
|
|
2. In **Bundled Plugins**, click **Install** for **Compound Engineering**.
|
|
3. Enable the plugin if it is not already started.
|
|
|
|
When installed and enabled, the plugin registers the **Compound Engineering**
|
|
dashboard view destination and installs its bundled `ce-*` skills into a
|
|
plugin-local, discoverable directory (never a global `~/.claude/skills` path).
|
|
|
|
**Built-in workflow gating:** the `builtin:compound-engineering` workflow is
|
|
hidden from the workflow picker and task workflow selection until this plugin is
|
|
installed and enabled. Once the plugin is active, the workflow appears
|
|
automatically alongside other built-in workflows — no additional configuration is
|
|
needed. If the plugin is uninstalled, the workflow is hidden again.
|
|
|
|
## Dashboard view
|
|
|
|
The Compound Engineering view is registered as a primary plugin destination
|
|
(`viewId: "compound-engineering"`).
|
|
|
|
It follows dashboard UI conventions: the view's panels, controls, responsive
|
|
layout, spacing, and radii use the shared `--space-*` / `--radius-*` design
|
|
tokens and shared button/card/input classes so the plugin remains visually
|
|
consistent across light, dark, desktop, and mobile surfaces.
|
|
|
|
It provides:
|
|
- An **artifact hub** that discovers CE artifacts from conventional locations
|
|
(`STRATEGY.md`, `docs/ideation/`, `docs/brainstorms/`, plan docs, `docs/work/`,
|
|
`CONCEPTS.md`, `docs/solutions/`) grouped by stage, with explicit
|
|
empty / partial / error states.
|
|
- Self-contained artifact previews read through plugin routes under
|
|
`/api/plugins/fusion-plugin-compound-engineering/`.
|
|
- A **stage launcher** listing the registered, operator-enabled stages.
|
|
|
|
## Sessions
|
|
|
|
Each stage maps to a bundled skill via the stage registry
|
|
(`{ stageId, skillId, artifactLocation, icon, label }`). Launching a stage starts
|
|
an interactive agent session on the host's `createInteractiveAiSession` seam.
|
|
|
|
The orchestrator streams `thinking`/`text` turns, surfaces a structured
|
|
`question` (pausing in `awaiting_input`), accepts a structured answer, and on
|
|
`complete` writes the artifact to the stage's conventional location. Lifecycle:
|
|
`launching → active → awaiting_input → completed`, plus `error` and
|
|
`interrupted`. Interrupt/error auto-saves progress and emits an observable event;
|
|
sessions resume/retry back to their current question.
|
|
|
|
Turn execution is **detached**: start/answer/resume return as soon as the
|
|
session row reflects the request, with the agent turn running in the background
|
|
(failures persist into session state — never an unhandled rejection). **Close**
|
|
only leaves the flow UI; it does not stop the detached agent. **Cancel** is the
|
|
explicit stop action for `launching`/`active`/`awaiting_input` sessions: it
|
|
aborts any live in-process handle, flushes live working output into history, and
|
|
keeps the session row as terminal `interrupted` with `Cancelled by user` so the
|
|
conversation can be inspected or resumed. **Discard** is different: it removes a
|
|
settled session row entirely after disposing any live handle.
|
|
|
|
While a turn runs, the engine streams mid-turn progress (thinking/text deltas + tool
|
|
markers) through the seam's `onProgress` option; the orchestrator buffers it
|
|
and `GET /sessions/:id` attaches it as transient `liveActivity`. The per-turn
|
|
timeout is **inactivity-based** (progress re-arms it), so long actively-working
|
|
turns are never killed; on settle/interrupt the working trace is condensed into
|
|
the conversation history. Users can also **steer** mid-stage: answers may carry
|
|
free-text guidance (`{value, comment}`) or be guidance-only (`{feedback}`).
|
|
|
|
Updates are **pushed** over the shared `/api/events` SSE stream: the orchestrator
|
|
emits via `ctx.emitEvent`, the host forwards them as project-scoped
|
|
`plugin:custom` events, and the view subscribes through the host
|
|
`subscribePluginEvents` capability (no raw `EventSource`). Polling
|
|
`GET /sessions/:id` remains a fallback. The `projectId` from `start` is threaded
|
|
through every answer/resume/poll so they resolve the session's owning store.
|
|
|
|
HTTP endpoints (under `/api/plugins/fusion-plugin-compound-engineering/`):
|
|
- `POST /sessions` → start a stage session
|
|
- `POST /sessions/:id/answer` → answer the awaiting question (send `projectId`)
|
|
- `POST /sessions/:id/resume` → resume an awaiting/interrupted session (send `projectId`)
|
|
- `POST /sessions/:id/cancel` → cancel an in-flight session; stops the agent and keeps the row as `interrupted`
|
|
- `GET /sessions/:id` → current persisted session state (push + poll fallback)
|
|
- `GET /sessions` → list sessions (filter by status/stage)
|
|
- `GET /sessions/:id/links` → the work→board pipeline-link records for a session
|
|
- `DELETE /sessions/:id` → discard a session; stops any live handle and deletes the row
|
|
|
|
## Sync model
|
|
|
|
Two separate state machines are kept in sync, never merged:
|
|
|
|
- **Board-task ownership** → the task `column`. The **board is authoritative for
|
|
task state**.
|
|
- **CE-pipeline ownership** → `ce_pipeline_state.{currentStage, status}`. The
|
|
**CE flow is authoritative for artifact/pipeline content**.
|
|
|
|
**Inbound:** `onTaskMoved` / `onTaskCompleted` hooks resolve the link and enqueue
|
|
a sync signal under the 5s hook budget — no inline advancement.
|
|
|
|
**Reconcile:** `reconcileCePipelines(ctx)` is a single on-demand sweep (not a
|
|
poll loop). It drains the queue and independently re-derives transitions from
|
|
live board state, so a dropped or never-enqueued event still converges.
|
|
|
|
**Outbound:** when a pipeline advances to a stage that produces board work, the
|
|
reconciler creates the next-stage board task and links it.
|
|
|
|
**Conflict policy:** the reconciler only reads already-terminal board columns and
|
|
only writes CE-owned fields plus a new board task, so the two writers never
|
|
contend over the same cell.
|
|
|
|
The work bridge tags every CE-originated board task (source `workflow_step` with
|
|
CE markers in `sourceMetadata`) and records an authoritative pipeline-link row;
|
|
created tasks then run the normal lifecycle untouched.
|
|
|
|
## Settings
|
|
|
|
Settings render under **Settings → Plugins → Compound Engineering**.
|
|
|
|
**Sessions**
|
|
- `defaultProvider` (string) — provider for CE interactive sessions; blank uses
|
|
the host default. Consumed by the orchestrator's factory call.
|
|
- `defaultModelId` (string) — model within the provider; blank uses the host
|
|
default. Consumed by the orchestrator's factory call.
|
|
- `disabledStages` (string[], default `[]`) — explicit opt-out list. Registered
|
|
stages launch by default; the orchestrator rejects only IDs listed here.
|
|
|
|
**Sync**
|
|
- `reconcileOnHooks` (boolean, default `true`) — auto-fire the reconcile sweep
|
|
after task move/complete hooks. When off, the hook still enqueues so an
|
|
on-demand sweep converges later.
|
|
- `reconcileIntervalMinutes` (number, default `15`) — cadence hint for an
|
|
on-demand refresh surface; not a continuous poll loop.
