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

Annotations already declare readOnly=false, destructive=false, idempotent=false and openWorld=false, so the safety profile is covered. The description adds that the write is immediate/synchronous, which is genuinely extra context, but it omits what happens on duplicate competitors (despite idempotent=false) and how aliases/domains affect tracking.

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?

Two short, front-loaded sentences with no filler; the action and its immediacy lead. It is terse to the point of under-informing rather than wasting words.

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 4-parameter mutation with no output schema and 0% schema description coverage, the description is too thin: it explains neither the roles of aliases/domains/project_id nor duplicate or error behavior. It leaves an agent under-equipped to call it 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% across 4 parameters, so the description must compensate, and it largely does not: aliases, domains, and project_id get no mention at all. Only "one more competitor" faintly implies a single name per call.

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?

States a concrete verb (track) and resource (competitor) in a specific domain (AI answers), so an agent immediately knows it mutates the tracked-competitor set. It does not explicitly distinguish itself from siblings, though no sibling covers competitor tracking.

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?

"Runs at once" implicitly contrasts with the prepare_*/confirm_change workflow siblings, hinting that this tool executes immediately without a confirmation step. However, it never names an alternative or states prerequisites/exclusions explicitly.

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