Conciseness

The body is lean: it gives path conventions, JSON command templates, and tight rules without explaining concepts Claude already knows, so every token earns its place.

Actionability

It provides copy-paste-ready JSON for ack_task and submit_task, exact path templates, the completion-message format, the blocker format, and an enumerated status list — fully executable guidance.

Workflow Clarity

The Acknowledge → Read spec → Execute → Submit → Completion Message sequence is explicit, with validation checkpoints (ack_task failure handling, BLOCKED instead of silent waiting, acting only after submit_task returns ok: true) for the stateful submit step.

Progressive Disclosure

This is a focused single-purpose skill with no external bundle files and no nested references; its well-organized sections (Task Directory, Acknowledge, Execute, Submit, Completion Message) satisfy the simple-skill note for progressive disclosure.

Specificity

The description lists multiple concrete actions — "acknowledges the task", "works inside shared/tasks/{task-id}/", "submits with taskflow submit_task", "publishes deliverables", "reports TASK_COMPLETED or blockers" — matching the anchor for several specific concrete actions.

Completeness

An explicit "Use when a Worker receives TASK_ASSIGNED..." clause answers "when", and the action list answers "what", satisfying the anchor for both what and when with explicit triggers.

Trigger Term Quality

It covers the natural system trigger terms a Worker would actually encounter — TASK_ASSIGNED, taskflow submit_task, TASK_COMPLETED, Task room, shared/tasks/{task-id}/, blockers — giving good coverage rather than jargon or a single keyword.

Distinctiveness Conflict Risk

The trigger is tied to a distinct teamharness Worker protocol (TASK_ASSIGNED, taskflow submit_task, Task room), occupying a clear niche unlikely to fire for unrelated skills.
