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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint as true/false appropriately, so the safety profile is covered. The description adds value by disclosing the response contents (counts per field/rule/constraint, mode, and a workflow_name field), which is especially important because there is no output schema.

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 sentences, each purposeful: the first states the action and returned details, the second provides a concrete downstream use. Zero filler.

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 simple list operation with rich annotations and a one-parameter schema, the description covers the account scope, the returned summary fields, and how to use the result (workflow_name for validate). No output schema exists, but the description fills in key return-value details.

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?

The single parameter api_key is fully documented in the schema with type and description ('GeodesicAI API key (gai_...)'), so the description adds no parameter-level meaning. With 100% schema coverage, 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?

The description opens with the specific verb 'List' and identifies the resource as 'Blueprints on this account,' then adds distinguishing detail: 'with field/rule/constraint counts and mode.' This clearly separates it from sibling create/update/delete/health 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?

The description provides an explicit downstream usage instruction: 'Use the returned workflow_name as "blueprint" in validate.' This gives clear context for when to call list_blueprints (before validation), though it does not explicitly contrast with alternative inspection tools like check_blueprint_health.

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