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

With readOnlyHint=true, idempotentHint=true, and destructiveHint=false already in annotations, the description adds meaningful behavioral context by disclosing that party matching follows USPTO indexed names and may combine similarly named entities, warning that totals may include multiple entities. This goes beyond the annotations and is critical for responsible interpretation of the results.

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 tightly packed sentences with zero filler. The first sentence front-loads the core purpose and deliverables, and the second adds a necessary caveat. Every word earns its place, making this highly scannable for an agent.

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 summarization tool with no output schema, the description adequately specifies what the summary includes and warns about identity aggregation. It does not mention edge cases such as empty results, pagination, or time-range filtering, but given the tool's moderate complexity and the annotations covering safety, it is sufficiently complete for an agent to invoke it correctly.

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 schema already defines 'party' as a company or party name. The description adds mild context by framing the party as a petitioner or patent owner and by implying that matching may be fuzzy, but it does not add syntax, formatting, or disambiguation guidance beyond the schema. Baseline 3 applies since the schema carries the parameter burden.

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 a specific verb ('Summarize') with a clear resource ('PTAB proceeding exposure for a petitioner or patent owner') and enumerates the output contents (roles, challenged patents, statuses, trial types, recorded outcomes). This distinguishes it from search-based siblings like ptab_search_proceedings and ptab_search_decisions by focusing on a consolidated party-level summary.

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 first sentence clearly implies the tool is for obtaining a party-centric PTAB exposure overview. However, it does not explicitly state when to prefer this over sibling tools such as ptab_patent_risk_profile or ptab_proceeding_timeline, nor does it provide explicit exclusions. The identity-verification caveat is useful but pertains to data interpretation rather than tool selection.

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