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

The readOnlyHint annotation already establishes this is a safe read. The description adds the underlying REST mapping (GET /v1/catalog/blueprints/{blueprint_id}.json), which corroborates the read semantics and identifies the resource path, but says nothing about the shape of the returned blueprint or failure behavior on an unknown id.

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 the purpose and followed by the REST endpoint. Every word earns its place with no redundancy.

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 single-parameter read tool with full schema coverage and an annotation covering the safety profile, the description is sufficient to invoke it correctly. It could go slightly further by hinting at what a blueprint contains or how it relates to sibling variant/provider tools, but nothing essential is missing.

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 the single parameter is documented in the schema, so the baseline is 3. The description only echoes the id via the URL template '{blueprint_id}' and adds no format, valid-range, or example guidance beyond the schema.

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 specific verb and resource: 'Get a single catalog blueprint's details.' The word 'single' implicitly separates it from the sibling printify_list_catalog_blueprints, but the sibling is never named, so the differentiation is inferable rather than explicit.

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?

Usage is only implied — fetch one blueprint by id rather than listing. There is no explicit when-to-use, no stated follow-on (e.g. pair with get_variants/get_print_providers), and no alternative named. Adequate but with a clear gap.

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