Send action email

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

Annotations are minimal (no hints for destructiveness or idempotency). Description merely states it sends an email, but does not disclose side effects (e.g., rate limits, email delivery expectations, user notification) or clarify what happens if the user has no email or if actions are invalid. With low annotation burden, description should provide more behavioral context.

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?

The description is a single short sentence, which is concise but lacks necessary detail. It is appropriately front-loaded but does not fully earn its place as it omits key information. Score reflects minimal viable 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?

Given the low schema description coverage and minimal annotations, the description is incomplete. It does not explain what the 'id' parameter represents, valid action values beyond two examples, or the expected outcome. A more complete description would include parameter details and usage context.

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 has 0% description coverage for parameters. Description provides examples of possible action values but does not formally describe the 'id' parameter (likely user ID) or the 'actions' parameter (array of required action types). This leaves ambiguity for an AI agent.

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?

Description clearly states the action (send email) and resource (user with required actions). Provides specific examples (VERIFY_EMAIL, UPDATE_PASSWORD) and distinguishes from sibling tools which are for listing, getting, or managing other entities.

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?

No guidance on when to use this tool versus alternatives. Does not state prerequisites (user must have email, actions must be enabled) or context for usage. Sibling tools like keycloak_user_logout serve different purposes but no comparison.

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