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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered by structured data. The description adds only 'tenant-owned', which usefully signals tenant scoping/permission requirements, but it does not say what readiness dimensions are checked or whether missing prerequisites are reported as errors or as flags.

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 front-loaded sentence with no filler, and the scope constraint ('one tenant-owned webinar') arrives before anything else. It is efficient, though the brevity edges into under-specification rather than true conciseness.

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?

No output schema exists, so the description should convey what 'readiness' covers, but it does not — the agent cannot anticipate the shape or vocabulary of the result. For a simple read-only single-parameter inspection tool this is acceptable minimum viability, but not complete.

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?

With one parameter and 0% schema description coverage, the description carries the burden; it implies a single webinar is targeted but never names or explains 'webinarId'. The schema itself supplies uuid format and a strict pattern, and 'tenant-owned' usefully constrains which IDs are valid, so the gap is partly mitigated.

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 specific verb ('inspect') and a specific resource ('setup readiness') scoped to a single webinar, which is clear enough to act on. It does not differentiate itself from the sibling workflow 'setup_end_to_end' or from the various getters like 'summary' or 'widget_style_get', so an agent cannot tell from the text alone whether readiness overlaps with diagnostics exposed elsewhere.

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?

There is no when-to-use guidance, no stated preconditions, and no mention of alternatives such as 'webinarstack.workflows.setup_end_to_end' for actually completing setup vs merely inspecting it. The agent is left to infer that this is a pre-flight check rather than a fixer.

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