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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds that this is a *public* profile view rather than internal company data, which is useful, but says nothing about auth requirements or what the returned profile excludes.

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?

One front-loaded sentence with the verb first and scope in a parenthetical; every word earns its place and there is no filler.

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 one-parameter read with full annotation coverage, this is serviceable, but the description is silent on two things an agent needs: how 'id' should be sourced, and how this differs from companies_get. No output schema exists, but that is mitigated because the parenthetical names the returned content.

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 0% and the single required 'id' (uuid) has no description in the schema. The phrase "a company's public profile" weakly implies the id identifies a company, but it does not confirm whether this is a company id, a domain, or another entity reference — a real ambiguity given the companies_* siblings.

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 specific verb (read) and resource (a company's public profile) and the parenthetical scopes what the profile contains (contact details, branding on landing pages). It is clear on its own, but it never distinguishes itself from the sibling companies_get, which an agent will plausibly consider the same resource class.

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 alternative is named. The natural companion tools, companies_get and company_profile_update, are left for the agent to sort out by guessing from names alone.

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