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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds genuinely new behavioral context: webhookSecret is redacted for webhook-action rules and meta_capi rules return a specific actionConfig shape, which an agent could not infer from structured fields.

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 sentences, front-loaded with the core action, then the two field-level caveats. No filler or restatement of the title.

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 usefully characterizes the return payload (full configuration, redacted secret, meta_capi actionConfig fields). It could say more about error behavior for unknown IDs or non-tenant-owned webinars, but it is largely complete for a simple two-UUID read.

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%, so the description must carry the burden, but it only implies that webinarId scopes to a tenant-owned webinar and automationId selects the rule. Both parameter names are self-explanatory UUIDs, so the gap is modest rather than severe.

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 and resource ("Retrieve one automation rule by ID") plus scope ("tenant-owned webinar"), which clearly separates it from list-style siblings. It does not name an alternative tool, so it stops short of a 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?

"by ID" implies the tool is for when an automationId is already known, which is useful implied guidance. However, there is no explicit when-to-use/when-not guidance and no mention of automations_list or automations_find_matching as the way to obtain an ID.

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