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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description still adds useful context by stating the returned payload shape (guidance + update schema) and explicitly denying any read or mutation of company records, which prevents an agent from assuming a side effect.

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?

Three short sentences, front-loaded with the return content and ending on the strongest constraint. The middle sentence about 'conversation or synthesis from supplied material' is the softest and earns its place least, but nothing is padded or repeated.

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 parameters, an output schema present, and annotations carrying the safety profile, the description supplies what an agent needs: what comes back and what it must not assume. It falls short only on the when-to-use framing relative to get_company_context, which is the one remaining gap.

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?

There are zero parameters and full schema coverage, so no parameter explanation is required. The baseline of 4 applies since the description correctly implies a no-argument call.

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 names a specific verb and resource: it returns shared company-context interview guidance plus the update schema. The final sentence ('Does not read or change company records') separates it from get_company_context and update_company_context, which are the nearest siblings, though neither is named directly.

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?

'Supports conversation or synthesis from supplied material' gestures at usage but is too abstract to route reliably. The exclusion of record reads implies 'use this to learn the interview structure, not to fetch data,' but the description never states the condition that selects this tool over get_company_context.

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