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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds two useful signals beyond that: the payload scope (readiness + stack + history) and the 'Pro' tag, which implies a paid/tier-gated capability worth knowing before calling. It does not cover any error/empty-result behavior.

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?

A single front-loaded sentence naming the resource first, then its contents. The trailing 'Pro.' is efficient but cryptic without further context, which keeps it from a perfect score.

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?

There is no output schema, so the description carries the return-value burden. It lists the three major content blocks, which is the minimum an agent needs, but says nothing about response shape, size, or whether the profile can be partially empty for a given company.

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%, so both parameters (slug, context) are fully documented in the schema itself, including the provenance of the slug. The description adds no parameter-level detail beyond that, which is the correct baseline when the schema does the heavy lifting.

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 resource (one company) and enumerates the payload contents: 40-dimension readiness, adopted stack, per-quarter history. The word 'Full' implicitly contrasts with the narrower company_dimensions/company_gaps/company_signals siblings, but no sibling is named outright, 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?

No explicit when-to-use, when-not, or alternative is given. The slug parameter's schema notes it comes from find_company_insights, which hints at a two-step find-then-get flow, but that routing lives in the schema, not the description, and no condition distinguishes this from the dimension-specific siblings.

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