Names the domain (Feishu permission management) and mentions documents and files, but doesn't list specific concrete actions like granting access, revoking permissions, listing collaborators, or changing sharing settings.

Answers both 'what' (Feishu permission management for documents and files) and 'when' with an explicit trigger clause ('Activate when user mentions sharing, permissions, collaborators').

Includes some relevant keywords ('sharing', 'permissions', 'collaborators') but misses common variations like 'access control', 'share link', 'invite', 'read-only', 'edit access', or 'Feishu docs'.

The combination of 'Feishu' and 'permission management' creates a clear niche that is unlikely to conflict with other skills, as it targets a specific platform and a specific functional area.

The content is lean and efficient. It assumes Claude understands APIs and JSON payloads, avoids explaining what permissions or collaborators are, and every section serves a clear purpose with no filler text.

Provides fully concrete, copy-paste ready JSON payloads for each action (list, add, remove), complete reference tables for all parameter values (token types, member types, permission levels), and realistic examples with plausible token formats.

The three actions are clearly documented individually, but there's no explicit workflow sequence or validation guidance for permission management, which is explicitly noted as a sensitive operation. Missing feedback loops (e.g., verify after adding/removing, check current permissions before modifying) for what the skill itself acknowledges is a sensitive/destructive operation.

For a skill of this scope (single tool, well-bounded functionality), the content is appropriately organized into clear sections—actions, reference tables, examples, and configuration—without needing external files. The structure supports easy scanning and discovery.
