 ## Usage

-For large, multi-stage work, the extension instructs Pi to call `set_tasks` before exploration as the only tool in the first batch. Smaller work remains untracked. Pi then updates task states at each real transition instead of reconstructing progress at the end.
+For work with three or more distinct steps, the extension instructs Pi to explore enough to understand the scope, then call `set_tasks` before implementation. Smaller work remains untracked. Pi then updates task states at each real transition instead of reconstructing progress at the end.

 After automatic or manual context compaction, the extension sends one short hidden reminder only when unfinished tasks exist. Pi calls `list_task` to recover the authoritative current IDs and statuses; the full tree is not injected on every model call.

 | Tool | Parameters | Behavior |
 | --- | --- | --- |
-| `set_tasks` | `{ mode, tasks, force? }` | `append` extends the tree; `replace` atomically installs a new tree or clears it with `[]`. Replacing unfinished work requires `force: true`. |
-| `update_task` | `{ tasks: [...] }` | Atomically patches multiple tasks. `parentId: null` moves to the root; `position` is a zero-based sibling index. |
+| `set_tasks` | `{ mode, tasks, force }` | `append` extends the tree with `force: false`; `replace` atomically installs a new tree or clears it with `[]`. Replacing unfinished work requires `force: true`. |
+| `update_task` | `{ tasks: [...] }` | Atomically patches multiple tasks. Use `null` for unchanged text/status, `parentId: -1` for unchanged or `0` to move to root, and `position: -1` to keep the current order. |
 | `rm_task` | `{ ids: [...], reason }` | Removes only mistaken, duplicate, or canceled tasks. Removing a parent cascades through its descendants. |
 | `list_task` | `{}` | Returns the full tree as compact `id/status/name` lines. |
-| `get_task` | `{ ids: [...] }` | Returns complete task details, including parent and child IDs. |

-Descriptions are optional, but useful scope, constraints, and done criteria improve recovery through `get_task`. IDs are not reused by append/remove operations; `replace` deliberately rebuilds IDs from `1`. Replace forbids `parentId`, so new hierarchy must use nested `children`. Multiple tasks may be `in-progress`. A parent can be marked `done` only when all descendants are also `done`.
+Task input keys are explicit so strict tool-schema bridges do not invent values for omitted properties. Use `description: null` when no detail is needed, `status: "pending"` for the default state, `parentId: null` for root tasks and nested children, and `children: []` for leaves. `prepareArguments` still expands legacy calls that omit these fields.

+
+A task starts timing the first time it enters `in-progress`. Leaving that state records a stop and pauses the timer; entering it again resumes with a new active segment while preserving the cumulative duration. Repeated updates with the same status, as well as name, description, hierarchy, and position changes, do not reset timing. For started tasks, `get_task` includes the first `startedAt` timestamp, a `stoppedAt` timestamp while paused, and cumulative `durationMs`. Timestamps use ISO 8601.

 ## Herdr Integration

-When Pi runs inside Herdr, the extension reports the most specific `in-progress` task as a `task` pane metadata token. If nothing is in progress, it falls back to a blocked task. Parallel current tasks use a separate `task_count` token so Herdr can truncate long task names responsively while keeping the remaining count visible, for example `#7 Implement auth · +2`.

Parallel current tasks use a separate `task_count` token so Herdr can truncate long task names responsively while keeping the remaining count visible, for example `#7 Implement auth · +2`.

lesetong	28d7e66d8a	fix: hoist $defs to the schema root for set_tasks Refs like "#/$defs/AddTask" resolve from the document root, but Type.Cyclic nested the $defs inside tasks.items, so the moonshot-flavored gateway reported "$defs not found for reference". Hoist all $defs entries to the parameter schema root and strip the synthetic $id that would change fragment resolution. Update the regression test to pin the layout. Bump version to 0.2.3.	2026-08-10 00:48:36 +08:00
lesetong	7971cf1a09	fix: emit #/$defs/ refs in set_tasks schema TypeBox Type.Cyclic generates bare local refs ("AddTask") which strict moonshot-flavored JSON Schema gateways (Console Go upstream) reject with HTTP 400. Rewrite all local $ref values to the #/$defs/ form after building the schema, and add a regression test asserting the ref format. Bump version to 0.2.2.	2026-08-10 00:45:54 +08:00
