get_note_timeline

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden. It usefully discloses that the tool directly reads timeline/original resources and explicitly returns unavailable when no timeline exists, but it does not describe the return shape, auth requirements, or whether it has any side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single compact sentence with the core purpose front-loaded, followed by the key fallback behavior. It is efficient, though '原文资源' is slightly vague and could be more precise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity, one-parameter read tool, the description covers the main action and a missing-timeline edge case. However, with no output schema and no annotations, it should ideally clarify return values and distinguish this tool from related note-content siblings.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There is only one required parameter, id, and the schema description coverage is 100%. The description adds no parameter-specific meaning beyond the schema, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific read operation and resource: it directly reads the structured timeline and original text resources of a recording or meeting note. The tool name and description make the core purpose clear, but it does not explicitly distinguish itself from close siblings such as get_note_chapters, get_note_transcript, or get_note_original.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only usage-like guidance is the fallback behavior when no timeline exists ('没有时间线时明确返回不可用'). It does not say when an agent should choose this tool over siblings that return chapters, transcripts, or original note content, nor does it list prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
