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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds substantial context beyond them: exactly which record classes are returned and that every line carries a public source link. It omits what happens on an unmatched company name, which caps it at 4.

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?

Front-loaded with the core purpose and scope in the first clause, then a single dense enumeration of returned record types. The list is long but each item earns its place as content disclosure; no filler sentences.

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?

With no output schema, the description correctly carries the burden of describing returns, and it does so thoroughly across award, device, patent, filing, and recall classes. It is only missing edge-case behavior (no match, multiple matches, volume limits) for a full 5.

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% for the single parameter, and the schema itself already documents the fuzzy-match behavior. The description repeats 'matched against the archive' without adding format, casing, or ambiguity-resolution detail, so baseline 3 applies.

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 ('composed mini-dossier on one US medtech company in the archive') and bounds the scope to registry records. It does not explicitly distinguish itself from likely-overlapping siblings such as company_timeline or deep_record, so it stops short of a 5.

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?

It never says when to use this versus alternatives like company_timeline or deep_record, nor any prerequisite or matching behavior beyond what the schema already states. The only guidance-like content is the trailing scope note 'Registry records only', which limits content rather than routing the agent.

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