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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description still adds real behavioral context: no inputs, no paid work, no provider calls, no platform-admin data, and per-API-key privacy for jobs and publication plans. The publication/human-review sentence is only loosely tied to context inspection, but it does disclose an organizational constraint the caller should know.

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 and scope are front-loaded in the first sentence, and the follow-up routing instruction lands at the end where it is easy to act on. Each sentence is short, though the publication/copy-only-plan sentence is tangential to a zero-input context read and slightly dilutes focus.

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?

This is a simple, zero-parameter tool with an output schema, so return values need no explanation. The description covers what the context contains (scope, versions, catalog coverage) and what it deliberately excludes, which is sufficient for correct invocation. Only a brief orientation note on how the context should change tool choice afterward 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 are zero parameters, so the baseline is 4, and the description reinforces this with 'No inputs'. Nothing further is needed for parameter meaning; the remaining sentences describe data boundaries rather than inputs.

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 gives a concrete verb and resource: inspect the authenticated organization's scope, versions and catalog coverage. It also hints at its orientation role ('before choosing tools') and distinguishes itself from webanto_get_capabilities, which it names as the follow-up. It stops short of explicitly framing itself as the entry-point/orientation tool versus the many other get_* siblings, so a 4 rather than 5.

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?

It states a clear usage moment ('before choosing tools') and an explicit follow-up alternative ('Follow with webanto_get_capabilities to diagnose authority'), which is stronger than most siblings. It does not say when NOT to use it or what it cannot answer beyond the data-boundary caveats, so no explicit exclusion guidance.

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