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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description still adds genuine context beyond them: findings are 'computed by fixed rules, never by a model' (trust/determinism), non-organization websites answer 'not found' (scoping behavior), and it details the ordering logic and what each finding contains. 'It changes nothing' duplicates readOnlyHint, but the rest is substantive.

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?

Purpose is front-loaded in the opening clause, and the following sentences each carry distinct information: ranking basis, evidence, causes and remedies, minor-finding marking, determinism, and the not-found case. It is dense but earns its length; the trailing 'It changes nothing' is the one redundant sentence given readOnlyHint.

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, the description carries the burden of describing the return value, and it does so well: findings ranked by goal, each with estimated effect, evidence numbers, likely causes, and suggested actions, plus minor-finding marking. The main omission is sibling disambiguation against webops_finding and the input format for 'domain,' but nothing essential to calling it correctly is missing.

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 one required parameter, 'domain,' with 0% schema description coverage; the schema only supplies a pattern and length bounds. The description implies the parameter identifies one of the organization's verified websites, which is useful context, but it never states the expected format (bare hostname vs. URL with scheme) or what happens for ambiguous input. With a single parameter and no output schema, this is adequate but leaves a real gap.

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 concrete resource and scope: 'For one of the organization's verified websites: the latest analysis and its findings ... ranked by the website's goal.' An agent knows this retrieves findings for a single site, and the 'verified websites' qualifier narrows the domain of applicability. It stops short of distinguishing itself from the near-identically named sibling webops_finding (singular) or from webops_daily/webops_pages, so a 5 is not warranted.

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: an agent can infer this is the tool for 'what to fix on one website,' and the title reinforces that. There is no explicit when-to-use versus the sibling webops_finding, webops_list_websites, or webops_daily, and no statement of when not to use it. The negative case is only partially covered by the note that a non-owned website returns not found.

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