get_v1_user_highlights

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

The description includes a billing note ('2 requests per call'), which is helpful, but no annotations are provided. It does not disclose whether the operation is read-only, what the 'force' parameter does regarding privacy checks, or other behavioral traits beyond billing.

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 extremely short (two sentences) but is not well-structured. The first line gives the endpoint, the second is a billing warning. It is concise, but the brevity sacrifices clarity and completeness.

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?

Given three parameters, no output schema, and no annotations, the description is highly incomplete. It fails to explain return values, the meaning of 'highlights', or how parameters affect results. The billing note is the only extra context, which is insufficient.

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?

Schema description coverage is only 33% (only 'force' has a description). The description adds no additional meaning to the parameters; it does not explain 'user_id', 'amount', or the context of 'force'. With low coverage, the description should compensate but does not.

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 'User Highlights' and gives the endpoint path, indicating it retrieves highlights for a user. However, it does not clarify what user highlights are or use a verb, making the purpose somewhat vague. It is differentiated from siblings that use username or v2 endpoints, but not clearly.

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?

No guidance is provided on when to use this tool versus alternatives like get_v1_user_highlights_by_username or get_v2_user_highlights. There is no mention of prerequisites or context for use.

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