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

Annotations already declare readOnly, idempotent, non-destructive and closed-world. The description goes further by disclosing the data-scoping behavior: only verified, opt-in records are returned and no private contacts or documents are exposed. It does not say what happens on a non-verified or missing ID, which is the remaining behavioral gap.

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 compact sentence with the resource scope front-loaded and the privacy guarantee appended. No filler and nothing redundant.

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 one-parameter read with full annotation coverage, the core is present. Still missing are the shape of the returned profile (no output schema exists) and the behavior on missing, unverified, or non-opted-in records, which an agent needs to handle failures correctly.

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 0%, so the description must compensate; 'opaque ID' is useful because it tells the agent the record_id is not a human-readable key. However, it never maps the term to the record_id parameter or notes the 1-36 character constraint, leaving partial compensation only.

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: 'Retrieve a verified opt-in public profile by opaque ID.' The resource name ('product' profile) implicitly distinguishes it from the sibling get_public_company_profile, though it never says so explicitly.

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?

Usage is only implied: you call it with an ID to read a public profile. There is no stated condition for choosing this over the near-identical get_public_company_profile sibling, and no guidance on what to do when a record is not verified or not opted in.

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