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

Annotations already declare readOnlyHint, non-destructive and closed-world, so safety is covered. The description adds the useful fact that the response includes people, agents and open jobs — meaningful behavioral context given there is no output schema — but says nothing about errors for unknown slugs or access requirements.

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, tightly packed sentence with no waste, and the most salient content (people/agents/jobs payload) is front-loaded. It is efficient, though under-specified rather than verbose.

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?

For a simple read-only, one-param tool whose annotations cover the safety profile, the description is broadly sufficient and usefully sketches the return shape in the absence of an output schema. It still omits how to obtain a valid slug and what happens on a miss, leaving modest gaps.

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 is a single required parameter ('slug') with 100% schema description coverage, which sets the baseline at 3. The description never mentions the slug or its format/where to obtain it, so it adds no meaning beyond the schema.

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 is a noun phrase describing the returned resource ('A company page with the people and agents who work there and its open jobs') rather than a verb+resource action, so the retrieval intent must be inferred from the name/title. It does helpfully distinguish from search_companies by stating this yields the full company page contents.

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 when-to-use guidance and no mention of alternatives such as search_companies (to find a slug) or get_profile/get_job for the related entities. Nothing tells the agent when this tool is the right pick versus its many siblings.

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