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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It describes a read operation ('Get'), implying it's likely safe and non-destructive, but doesn't specify any behavioral traits such as rate limits, authentication needs, data freshness, or pagination. The description is minimal and lacks context about how the data is retrieved or any operational constraints.

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, efficient sentence that directly states the tool's purpose without any unnecessary words. It's front-loaded with the core action and resource, making it easy to parse. There's no wasted text, and it effectively communicates the essential information in a compact form.

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?

The description is minimal but adequate for a tool with no parameters and an output schema (which handles return values). However, given the complexity implied by the tool name (involving ownership changes, business scope changes, and trading method transitions) and the lack of annotations, the description could benefit from more context about data sources, limitations, or typical use cases to fully guide the agent.

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 input schema has 0 parameters with 100% coverage, meaning no parameters are documented in the schema. The description doesn't mention any parameters, which is appropriate since none exist. This aligns with the baseline expectation for a tool with no parameters, as there's nothing to compensate for, and the description doesn't need to add parameter details.

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 clearly states the verb 'Get' and the resource 'companies with ownership changes and major business scope changes that were changed to trading method.' It specifies the type of companies retrieved (those with ownership and business scope changes that transitioned to trading method), which distinguishes it from general company retrieval tools. However, it doesn't explicitly differentiate from similar siblings like 'get_companies_ownership_changes_business_scope' or 'get_companies_with_business_scope_changes', which might overlap in scope.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention any prerequisites, exclusions, or specific contexts for usage. Given the many sibling tools (e.g., 'get_companies_ownership_changes_business_scope'), there's no indication of how this tool differs in application, leaving the agent to infer based on the name and description alone.

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