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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the shape of the returned data (growth, peer comparison, page), which is useful context, but says nothing about read-only safety, auth/permission needs, rate limits, or whether a missing company errors or returns empty.

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 tight sentence with the scope front-loaded, no filler. The trailing 'and its page' is slightly ambiguous but costs little.

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 no annotations, the description must cover return values, which it partially does. For a simple one-parameter read tool this is roughly adequate, but the absence of routing guidance and any error/behavior notes leaves 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?

Schema coverage is 100% and there is a single parameter whose description already documents format and example ('supabase.com'), so the schema does the heavy lifting. The description adds no syntax or constraint details beyond that baseline.

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 clear resource (one company) and enumerates what is returned: per-signal growth, peer comparison, and page. The retrieval verb is only implied by the name rather than stated, and no sibling is named, but an agent can tell this is the single-company lookup distinct from list_groups or rising_companies.

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?

There is no when-to-use or when-not-to-use guidance and no alternatives referenced, even though siblings like find_breakouts and rising_companies cover overlapping territory. The agent must infer the routing from the tool name alone.

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