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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does state meaningful side effects: propose offers slots, reschedule replaces slots, and cancel revokes an invitation. However, it does not disclose permissions, persistence effects, notifications, or what happens after a successful action.

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 compact, well-organized around action= segments, and front-loaded with the core purpose. The bilingual summary in English is slightly redundant with the Russian text but does not significantly hurt readability.

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 an 11-parameter tool with three distinct action modes and no output schema, the description provides sufficient high-level routing and conditional parameter requirements. Combined with the rich 100% schema descriptions, an agent can construct a valid call, though it lacks clarification around output behavior or error cases.

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 coverage is 100%, so the baseline is 3. The description adds value by mapping each action to the required parameter set (e.g., reschedule needs conversationId and proposedSlots; cancel needs conversationId) and by specifying the ISO-8601 UTC format for slots, which is not fully captured in every parameter schema description.

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 states a precise operation on a specific resource: propose, reschedule, or cancel an interview with the candidate. It lists the three action modes explicitly, which makes the tool clearly distinguishable from siblings like message_candidate or send_vacancy.

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 explains what each action does and which parameters are needed, but it gives no explicit guidance on when to prefer this tool over alternatives or when not to use it. Sibling tools are not referenced, and no exclusion conditions are provided.

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