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

With no annotations, the description carries the full burden and does substantial work: it discloses that output is a reviewable draft rather than a submitted request, that explicit authorization is a precondition, and that invocation costs $0.50 USDC on Base via x402. Remaining gaps are the mechanics of an unsupported broker match and any failure/refund behavior on the paid call.

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?

Three short sentences, front-loaded with the action, then the safety constraint, then the payment term. Nothing is redundant and each sentence contributes a distinct fact an agent needs before 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 two-parameter tool with no output schema and no annotations, the description covers what is produced (a drafted request), the authorization gate, and the cost model. It stops short of describing what the draft contains or what happens when no removal path matches, which is the only meaningful omission.

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% with only two documented parameters, so the schema already explains 'link' and 'fullName'. The description adds only the qualifier that the link should be an authorized listing, which is marginal meaning beyond the structured fields — 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?

The description names a specific verb chain and resource: it matches a data-broker listing to removal paths and drafts a CCPA/GDPR request. That is far more precise than the audit/scan siblings (opsec-score, threat-scan), though it never explicitly contrasts itself with full-privacy-sweep or spam-caller-removal, so the sibling boundary is inferred rather than stated.

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?

Usage context is implied by 'authorized data-broker listing' and the no-submit-without-authorization clause, which tells an agent this is a single-listing drafting step, not a bulk sweep. However, it never says when to prefer it over full-privacy-sweep or what to do when a listing has no supported removal path, so the agent must infer the routing.

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