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

With no annotations provided, the description carries full burden. It adds 'physics-aware' as a behavioral constraint (tricks follow physics rules), but lacks critical details: whether generation is deterministic/random, if results are persisted, or if there are rate limits/side effects.

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?

Efficient two-part structure: single-sentence purpose statement followed by structured Args documentation. No redundancy or filler; every element earns its place.

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?

Given the presence of an output schema (not shown but indicated) and single-parameter simplicity, the description adequately covers core functionality. Minor gap: lacks note on whether generation is stochastic or deterministic, which would help set agent expectations for repeat calls.

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?

Despite 0% schema description coverage (only title and type present), the Args section fully compensates by documenting num_tricks with semantic meaning ('chain together in the combo'), constraints ('between 1 and 20'), and default value ('Defaults to 3').

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 uses specific verb 'Generates' with clear resource 'physics-aware sequence of wizard-style inline skating tricks', clearly distinguishing it from sibling retrieval tools (get_tricks_by_category, list_trick_categories) that merely query existing data rather than create sequences.

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 guidance provided on when to use this tool versus the sibling retrieval tools, nor any prerequisites (e.g., whether certain categories must be listed first). The description states what it does but not when an agent should choose it over alternatives.

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