item_get_takes_count

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

The annotation readOnlyHint=true already signals that this is a safe read operation. The description consistently describes returning a count, which aligns with the annotation, but it adds no additional behavioral details such as error conditions, return format, or reliance on the current timeline. With annotations covering the safety profile, the description's minimalism is acceptable.

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 concise sentence, front-loaded with the core action and resource. There is zero redundant text, and every word contributes to meaning, making it an exemplar of brevity.

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 simple read-only count tool with complete schema descriptions and an output schema present, the description is clear and sufficient. It doesn't mention prerequisites like the current timeline, but the schema and tool name provide enough context. It could be more explicit about how the item is located, but the overall definition is complete for its simplicity.

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?

The input schema has full 100% description coverage for all three parameters (item_name, track_type, track_index), so the schema already documents their meaning. The tool description does not add extra explanation about parameters, which is acceptable given the baseline of 3 when schema coverage is high.

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 clearly states the tool's function: 'Return the number of takes on a timeline item.' This is a specific verb (return) plus resource (takes on a timeline item), and it clearly distinguishes from sibling tools like item_get_take_by_index or item_delete_take_by_index by focusing on counting rather than accessing or modifying takes.

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 description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. It is a standalone sentence without any contextual hints about when counting takes would be appropriate, despite being one of many item_* tools.

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