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

No annotations are provided, so the description must disclose behavioral traits. It hints at the output content (creative insight, signature move, brand vibe) but does not explicitly state read-only, idempotency, or side effects. The inference is reasonable for a retrieval tool, but lacks explicit transparency.

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?

The description is a single, 14-word sentence that front-loads the action ('Get a single inspiration card by slug') and includes parenthetical detail. No redundant information; every word adds value.

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?

Without an output schema, the description should explain return values. It mentions 'full creative insight, signature move, brand vibe', providing insight into the response content. This is adequate for a simple retrieval tool, though a more explicit structure listing would raise completeness further.

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 coverage is 100% with description 'Inspiration slug from get_inspirations', and the tool description adds 'by slug'. This combination provides context that the slug originates from another tool, enhancing semantic understanding beyond the schema alone.

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 clearly states the tool retrieves a single inspiration card by slug, specifying the content includes 'full creative insight, signature move, brand vibe'. This distinguishes it from sibling 'get_inspirations' which lists cards, making the purpose specific and differentiated.

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 and parameter schema reference 'slug from get_inspirations', implicitly guiding users to first list cards to obtain the slug. However, it does not explicitly exclude alternatives like 'get_brand_moves' or provide when-not-to-use scenarios, but the guidance is clear enough for typical use.

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