The content is lean and efficient. It doesn't explain what Feishu is or how APIs work—it jumps straight into token extraction, action schemas, and concrete JSON examples. Every section earns its place with no filler.

Every action includes a complete, copy-paste-ready JSON payload with specific parameter names and example values. Limitations (e.g., markdown tables not supported) and important notes (e.g., owner_open_id for permissions) are clearly called out.

The 'Reading Workflow' section provides a clear 3-step sequence with a conditional check, which is good. However, there's no validation/error handling guidance for write operations (write, delete_block, create_table), and no feedback loops for potentially destructive operations like 'write' which replaces the entire document.

The content is well-organized with clear section headers and a logical progression from simple to complex actions. However, at ~150 lines with detailed JSON examples for 12+ actions, some content (e.g., table operations, image upload details) could be split into referenced files. As a standalone file with no bundle, it's a borderline monolithic reference.

Names the domain (Feishu documents) and mentions 'read/write operations' as actions, but doesn't list specific concrete actions like creating, editing, formatting, or extracting content from documents.

Clearly answers both 'what' (Feishu document read/write operations) and 'when' ('Activate when user mentions Feishu docs, cloud docs, or docx links'), with explicit trigger guidance.

Includes natural keywords users would say: 'Feishu docs', 'cloud docs', 'docx links'. These cover common variations of how users refer to Feishu documents.

'Cloud docs' and 'docx links' could overlap with other document-handling skills (e.g., Google Docs, general document processing). 'Feishu' is distinctive, but the other trigger terms introduce some conflict risk.
