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

No annotations are provided, so the description carries the burden of behavioral disclosure. It clearly indicates this is an analysis operation (not a mutation) and lists the analytical dimensions covered. However, it does not disclose whether the data is live, cached, or whether any external dependencies exist (e.g., docket API availability). It also doesn't mention any limitations such as patent coverage by jurisdiction, which could affect results. The description is functional but not deeply transparent.

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, well-structured sentence that front-loads the core purpose ('Analyze the European litigation posture of a specific patent') before enumerating the detailed aspects. Every word adds value, with no filler or repetition. It is concise and effective.

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 there is no output schema, the description must convey what the tool returns. It enumerates the key analysis areas (UP status, opt-out risk, SEP/FRAND classification, active proceedings across courts), which gives a solid picture of the output scope. However, it does not mention the structure or format of the returned data (e.g., whether it's a summary object, list of proceedings, etc.), which could leave an agent unsure about how to consume the result. This is a minor gap in an otherwise comprehensive description.

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 schema covers 100% of the single parameter with a clear description and example ('EP3883351' or 'EP2154874'). The description itself does not add additional parameter semantics beyond what the schema already provides, which meets the baseline for full schema coverage. No extra context is given for parameter format, but the schema is sufficient.

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 states a specific verb ('Analyze'), a specific resource ('a specific patent'), and enumerates the exact scope (UP status, opt-out risk, SEP/FRAND classification, active proceedings across UPC, UK, EPO, national courts). It clearly distinguishes itself from siblings like get_case_intelligence (focused on case details), get_judge_benchmarks (judge analytics), and search_european_dockets (search across dockets).

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 implies its use case (analyzing a patent's European litigation posture) but does not explicitly state when to prefer this over siblings, nor when not to use it. There are no alternative tool names mentioned, so the agent must infer selection based on the described scope, which is reasonably clear but not explicit.

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