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

Annotations indicate readOnlyHint=false, destructiveHint=true, idempotentHint=true, openWorldHint=true. The description adds meaningful behavioral context: it sends a verified-email code, requires the person to inspect gaps and proposed decision, and explicitly states it cannot clear gaps, approve contents, or agree to production. This goes beyond the annotations and clarifies the side effects and limitations. No contradiction with annotations.

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 three sentences, each earning its place. The first sentence states the core action and options. The second sentence discloses the email-code behavior. The third sentence lists exclusions. It is front-loaded with the primary purpose and avoids fluff.

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 mutation tool with no output schema, the description covers the key behavioral aspects: what it does, how it communicates (verified-email code), and what it cannot do. It doesn't describe the return value or what happens after the reviewer confirms, but the annotations (idempotentHint, destructiveHint) and the explicit limitations provide enough context for an agent to invoke it correctly. The main gap is not explaining the qualificationRevision structure, but that is partially a parameter semantics issue.

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 only 25%, with only idempotencyKey having a description. The tool description does not explain the meaning of qualificationRevision, decision, or reason beyond what the schema shows. The description mentions 'bid, no_bid or hold' which maps to the decision enum, and 'exact qualification' hints at qualificationRevision, but it doesn't clarify the nested object structure or the reason field's role. Baseline 3 is appropriate because the description adds some context but doesn't fully compensate for the low schema coverage.

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 action: 'Ask a reviewer to confirm bid, no_bid or hold for the exact qualification.' It specifies the resource (qualification) and the decision options. It also distinguishes itself from related tools by noting it cannot clear gaps, approve contents, or agree to production, which helps differentiate from other request/confirm tools.

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 implies when to use this tool: when a reviewer must confirm a bid decision for a qualification. It explicitly states what it cannot do, which serves as a partial exclusion. However, it doesn't name specific alternative tools (e.g., helvabase_confirm_bid_decision or helvabase_submit_qualification) or provide explicit when-not-to-use conditions beyond the limitations.

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