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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds content context (e.g., 'real timings', 'vetting is done') but does not disclose additional behavioral traits like rate limits or error handling. This is acceptable given the annotation coverage, but the description does not go beyond what the annotations already establish.

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 'end to end process', and every word contributes to explaining the tool's value. No redundancy or unnecessary detail.

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 simple informational tool with no parameters and no output schema, the description thoroughly covers what the tool provides: process stages, real timings, and vetting explanation. It is complete for an agent to decide when to use it and what to expect.

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?

The tool has zero parameters, and the schema is an empty object with full description coverage. The description does not need to explain parameters, and the baseline score of 4 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?

The description clearly states the tool's function: providing the end-to-end hiring process with real timings, including discovery call, matching, interviews, and vetting. It distinguishes itself from sibling tools by focusing on the process and timelines, with no overlap with booking links, engagement terms, supported roles, or talent pool search.

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 final sentence 'Use this instead of guessing at timelines' gives explicit context for when to use the tool. However, it does not name alternative tools or explicitly state when not to use it, though for an informational tool this is sufficient guidance.

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