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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds genuine behavior beyond that: webhookSecret is redacted from webhook-action rules in every emitted row, and meta_capi rules return their stored actionConfig with named fields. It does not describe empty results or pagination termination, which keeps it from a 5.

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?

Four sentences, front-loaded with the purpose, then filters and pagination, then two return-shape notes. Each sentence carries information an agent would not get from the schema, so the length is justified. Slightly dense but well-ordered.

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 read-only list tool with no output schema, the description should explain the general returned row shape and how pagination terminates (e.g., presence of a next cursor). It covers redaction and one action type's config but not the overall response envelope, leaving an agent to infer the list structure.

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 six parameters, so the description must compensate; it does name the three filter parameters and cursor/limit pagination, adding meaning beyond bare property names. However, it gives no formats, defaults, max limit, or guidance on triggerType/actionType interplay, leaving half the semantic burden unmet.

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+resource: 'List automation rules for a tenant-owned webinar'. It is clearly the enumeration tool among siblings such as automations_get, automations_find_matching, automations_update and automations_delete, and the tenant-owned scoping adds precision.

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?

The description identifies the optional filters (enabled status, trigger type, action type) and pagination support, which gives clear context for when this enumeration tool applies. It never explicitly names an alternative or exclusion (e.g., when to prefer automations_find_matching), so it falls short of the 5 bar.

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