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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered structurally. The description adds nothing beyond that: no pagination behavior, no filtering semantics, no note on response shape or limits. It does not contradict the annotations.

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?

It is short, but the first sentence is duplicated verbatim, wasting the only structural emphasis available. There is no front-loaded statement of intent beyond the raw path.

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 generic REST-wrapper endpoint with an untyped query object, no output schema, and 0% parameter coverage, the description should explain at minimum what resource is listed and what can be filtered. The delegation to describe_operation covers request schemas but leaves the agent without enough to call this correctly.

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 0% and both parameters ('query' and 'params') are opaque open objects with no property documentation. The description provides no parameter meaning whatsoever, so it fails to compensate for the coverage gap.

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 is literally 'GET /api/pbc-requests' twice, which restates the tool name and title without explaining what a PBC request is or how this list endpoint differs from siblings like get_pbc_requests_by_id or get_pbc_requests_summary. An agent learns only that it is an HTTP GET on that path.

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 when-to-use or when-not-to-use guidance is given. The single actionable hint is the pointer to describe_operation for native request schemas, which is a discovery aid rather than selection guidance between this and the many sibling pbc/request tools.

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