get_v4_user_activities

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

No annotations are provided; the description only indicates a read operation and that no API key is needed. It omits important behavioral details such as side effects, data freshness, pagination, or response format, leaving the agent underinformed.

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, efficient sentence that conveys the tool's purpose. It is concise but could benefit from slight restructuring to separate the list of activities from the API key note.

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 the tool has only 2 parameters and no output schema, the description lists transaction types but lacks information on pagination, time range, ordering, or return structure. This is minimally adequate but could be more complete.

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 coverage is 100%, so the schema already describes both parameters. The description does not add any additional meaning or context beyond what is in the schema, so a 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 clearly states the tool retrieves a user's Aave V4 transaction history and enumerates specific types (supplies, borrows, etc.), distinguishing it from sibling tools like get_v4_user_borrows or get_v4_user_supplies that return narrower subsets.

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 mentions 'No API key needed' as a convenience, but it does not provide explicit guidance on when to use this tool versus alternatives like get_v4_user_supplies. Usage context can be inferred but is not directly stated.

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