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

No annotations exist, so the description carries the full burden and does well: it declares 'Read-only', states 'Requires outcomes.read', clarifies that tracking capacity does not block outcome measurement, and explains that allowanceStatus counts are null when not measured. It does not cover pagination or the shape of the returned URL list.

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, but the middle sentences are dense and mix concerns (plan_limit meaning, upgrade remedy, plan determining crawl allowance) in one clause-heavy line. With no output schema the field-level detail is defensible, yet the passage could be tighter and better structured.

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 annotations and no output schema, the description supplies the key missing context: read-only safety, required scope, allowanceStatus values (at_limit/beyond_plan) and their null behavior, and remediation. The return shape of the saved-URL list itself is the main remaining gap.

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?

The single actionId parameter has 0% schema description coverage, but the description compensates: it ties actionId to 'a completed action' and explicitly says to omit it for project-wide capacity and allowance status. That is meaningful semantics beyond the bare uuid type.

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 specific verb (read) and precise resources: saved published URLs, page-tracking capacity, and crawl availability for a completed action. An agent can distinguish it from get_page_metrics or get_page_guard_rails by the tracking/allowance focus, though no sibling is named 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?

Gives concrete conditional usage: 'Omit actionId for project-wide capacity and allowance status' tells the agent when to scope to a project vs a single action, and 'Never ask the customer to resubmit a saved URL' plus the plan_limit upgrade remedy define how to act on the result. It stops short of explicitly contrasting with alternative sibling tools.

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