get_member_activities

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

No annotations exist, so the description carries the full burden. It usefully discloses the shape of the return (daily per-member counts) which helps since there is no output schema, and 'Retrieve' implies a read-only operation. However it says nothing about pagination behavior despite pageCursor/limit parameters, nor about rate limits or permissions.

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?

Two short sentences, front-loaded with what the tool does followed by what it returns. No filler, though the second sentence slightly restates the first's resource focus.

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 four-parameter read tool with no annotations and no output schema, the description partially compensates by describing the return content, but omits pagination semantics (pageCursor interplay) and scoping/permission context, leaving gaps an agent would need.

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 100%, and all four parameters (limit, dateFrom, dateTo, pageCursor) are documented in the schema with defaults, ranges and ISO 8601 format examples. The description adds no parameter-level detail, so baseline 3 applies.

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?

Names a specific verb ('Retrieve') and resource ('member activity metrics') and describes the returned payload (daily activity data with feature/note/board creation counts). It is clear what the tool does, though it never explicitly contrasts itself with the sibling get_member or list_members tools.

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?

There is no when-to-use guidance, no mention of prerequisites, and no routing to alternatives such as get_member or list_members. Usage is only implied by the verb 'Retrieve'.

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