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

Annotations already declare the safety profile (not read-only, idempotent, non-destructive). The description adds real behavioral context beyond that: the exact verification artifact (/.well-known/privi-scan.txt) the check depends on and the side effect of marking org ownership. It omits failure behavior when the token is absent or mismatched.

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?

A single sentence that front-loads the check and then states the outcome, with zero filler. It is efficient, though the ordering slightly buries the org-verification result, which is the agent's primary motivation for calling.

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 one-parameter tool with full schema coverage and annotations carrying the safety profile, the description covers the mechanism and the effect adequately. The remaining gap is sequencing within the scan_claim_start/verify flow and any error path, but no output schema exists that would need explaining.

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?

Only one parameter and schema coverage is 100%, with the schema itself documenting the accepted 'mcp_... id or endpoint URL' format. The description adds nothing about the server argument, so the baseline 3 for schema-carried semantics 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 concrete verb-and-effect pair: check the token at a named well-known path, then mark the org as verified owner. This is distinguishable from scan_claim_start, which the 'Finish claiming' title implies is the preceding step, though the description itself never names that relationship.

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 word 'Finish' in the title and the verify-and-mark framing imply this is the closing step of a claim flow whose start is scan_claim_start, but no sentence states when to call it, what precondition must hold, or when to use scan_claim_start instead. Usage is inferred rather than stated.

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