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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds only that profiles must have 'previously been created,' a minor scope note; it discloses nothing about pagination behavior, default page size, or ordering beyond what the schema already documents.

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?

A single efficient sentence with no wasted words. It is front-loaded on the core action, though the endpoint phrasing ('This endpoint retrieves...') is slightly boilerplate versus a direct verb-first statement.

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?

With an output schema, rich annotations, and 100% schema coverage, the definition is minimally viable. However, for a list tool in a suite containing get_profile, create_profile, update_profile, and delete_profile, it lacks the routing guidance an agent needs to pick 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 100%; both size and offset are fully documented in the schema including the default of 10 and how to use current_offset. The description adds no parameter meaning beyond the schema, so the 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?

States a clear verb+resource: retrieving details of all previously created profiles. The word 'all' implicitly distinguishes it from the singular sibling get_profile, but it never names that sibling or explicitly scopes the list, so differentiation is left to inference.

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 statement of when to use this versus get_profile (single profile) or create_profile/update_profile. The agent must infer that this is the enumeration tool and that pagination parameters should be supplied for large collections, with no guidance in the description.

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