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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the concrete shape of the returned records, which matters because no output schema exists, but it says nothing about pagination, date-range behavior, or whether the list can be empty.

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 compact clauses, front-loaded with the resource and followed by the returned fields. The trailing 'GET /0/candidates/{id}/events' is mild redundancy but confirms the scope cheaply.

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 single-parameter read tool with annotations covering safety, the description's enumeration of returned fields largely carries the burden left by the absent output schema. Only pagination and empty-result behavior are missing, which are minor for this shape.

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 100% and the single candidate_id parameter is already documented as 'Taleez candidate id.' The description adds no format, range, or sourcing guidance beyond what the schema provides, so baseline 3 applies.

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 resource (events for a candidate) and enumerates the returned data: subject, start/end, location, meeting URL, attendees. It is clear enough to distinguish from taleez_get_candidate, but it never explicitly contrasts with the sibling taleez_list_events, which appears to serve the same domain with a different scope.

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 says what it fetches but not when to choose it over taleez_list_events or the other candidate sub-resources. There are no stated prerequisites, scope notes, or exclusions, so an agent must infer from the names alone that this is the candidate-scoped variant.

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