Conciseness

Every line is operational — path rules, ownership tables, exact messages to send, and failure directives. No concept explanations, no padding, no repetition; the whole body is well under a page and every token earns its place.

Actionability

Copy-paste-ready guidance throughout: exact paths ('shared/tasks/{task-id}/spec.md'), a concrete filesync JSON pull payload, an exact message to tell Workers, and a precise retry policy ('if it still fails after one retry, report a filesync/shared-directory issue'). Common cases are covered by specific examples.

Workflow Clarity

Each workflow is clearly sequenced with explicit validation checkpoints and feedback loops: 'If a directory pull fails, stop and report the sync failure; do not fall back to partial file pulls', and the numbered troubleshooting flow (verify → instruct pull → retry once → escalate). Sync operations have their failure handling explicitly stated.

Progressive Disclosure

The skill is short, self-contained, and single-purpose with no bundle files; nothing here belongs in a separate reference. Sections are well-organized under clear headers (Local Abstraction, Team Task Files, Task Directory Sync, Refresh Project Files, troubleshooting), making navigation trivial with zero nested references.

Specificity

The description lists several concrete trigger contexts — 'project directories, global-shared inputs, non-task shared files, listing shared paths, or troubleshooting missing files' — plus explicit exclusion of task-level sync. Minor gaps: it never states what the skill actually does (path conventions/abstraction), so it falls just short of the comprehensive anchor.

Completeness

The 'when' is explicit and strong ('Use before filesync calls for...'), and the negative boundary ('Do not use for task-level sync') is clear, but the 'what' — that the skill provides local shared-path conventions — is only implied rather than stated. Both halves are present with one could-be-more-explicit, matching the anchor 4 example.

Trigger Term Quality

Good natural keyword coverage: 'shared files', 'shared paths', 'missing files', 'sync', 'filesync calls'. A few user-natural synonyms or concrete path examples (e.g. 'shared/projects/', 'shared/tasks/') are missing, keeping it below the comprehensive-synonym anchor.

Distinctiveness Conflict Risk

It carves a clear niche (filesync for shared files) and explicitly disambiguates from the closest overlapping skill: 'Do not use for task-level sync; taskflow delegate_task and check_task handle task directory sync internally.' Minimal conflict risk.
