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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description is not relied upon for safety. It adds useful behavioral context: the 'live' nature, a signed receipt (ML-DSA-65), and pricing ($1.00 USDC per call). However, it stops short of describing response structure or any edge-case behavior, so it earns a middle score.

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 sentence that packs in the core purpose, content domains, receipt detail, and pricing. It is concise and front-loaded, though the long comma-laden structure could be split into two sentences for readability without losing information.

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 and 0% schema description coverage, the description leaves important gaps: what 'focus' accepts, what the returned synthesis looks like, and any caveats about the 'named company' requirement. The pricing and receipt are helpful but do not compensate for the missing parameter semantics and selection guidance.

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 0%, so the description must carry the burden of explaining the two parameters. It indirectly covers 'company' via 'named company' but says nothing about the 'focus' parameter, its purpose, or its relation to the synthesis. This is a significant gap for a paid, parameterized tool.

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 ('synthesis') and resource ('company intelligence') and names concrete content areas: recent litigation, regulatory exposure, financial and news developments. This is clear and distinguishable from many siblings (e.g., get_case_law_synthesis, get_regulatory_news_synthesis) by its comprehensive scope, though it does not explicitly name any sibling as a contrast.

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 mentions a use case ('for due diligence workflows') but provides no guidance on when to use this tool versus the many related siblings, nor any exclusions or alternatives. Given the huge sibling list, an agent receives no routing help beyond the broad 'company intelligence' purpose.

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