Lists multiple concrete actions: read and update PRD, start a new work item, mark something complete, add an open question. Also mentions per-dev subdir isolation for conflict avoidance—very specific.

Clearly answers both 'what' (read and update the team's shared PRD, enforce per-dev subdir isolation) and 'when' (explicit trigger clause covering multiple scenarios like asking about work status, starting items, marking complete, adding questions).

Includes natural trigger terms users would say: 'current/inflight/done work', 'start a new work item', 'mark something complete', 'add an open question', 'team's spec', 'PRD'. Good coverage of how users would phrase these requests.

Highly distinctive: targets a specific artifact (team PRD in AFS workspace), specific operations (work item management, open questions), and a specific architectural constraint (per-dev subdir isolation). Unlikely to conflict with other skills.

The content is lean and efficient. Every section serves a purpose—layout convention, conflict rules, identity establishment, and workflows are all necessary and non-obvious domain knowledge. No unnecessary explanations of basic concepts.

The guidance is concrete with specific file paths, naming conventions, and markdown templates, but lacks executable MCP tool invocations (e.g., actual read_file/write_file/file_replace commands). The steps describe what to do but don't show exact tool calls Claude would use.

Multi-step processes (starting work items, marking done, adding questions) are clearly sequenced with explicit steps. The 'read before write' reflex serves as a validation checkpoint, and the append-only/single-writer rules provide clear guardrails against destructive operations.

For a skill with no bundle files, the content is well-organized into clearly labeled sections with a logical progression from layout → rules → identity → workflows. The CONVENTIONS.md reference and directory structure serve as natural navigation aids. No monolithic walls of text or deeply nested references.
