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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety bar is partly covered. The description adds meaningful context beyond that: the preview/owner-approval requirement, requestId reuse for recovery, and the 'claim live only when status is active' status gate. It stops short of describing irreversible effects on entities the label was attached to.

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?

Four short sentences with the operation and confirmation gate front-loaded. The trailing 'Fields: soclo://...' pointer adds little and 'Claim live only when status is active' is slightly cryptic, but overall it is efficient.

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 destructive mutation with no output schema, the description covers the safety/confirmation workflow adequately. It omits what removal does to label associations on existing entities and what a success/failure response looks like, leaving some behavioral gaps given the complexity.

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 50%. The description reinforces the semantics of two parameters (confirm and requestId reuse), which the schema also documents. It does not add meaning for labelId, accountId, platform, or adAccountId, so it only partially compensates for the coverage gap.

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 clear verb+resource: 'Remove a Google Ads label.' An agent can tell it deletes a label object. However it does not distinguish itself from nearby siblings like soclo_ads_detach_ad_label, soclo_ads_update_ad_label, or soclo_ads_create_ad_label, so the sibling differentiation is left to inference.

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?

Gives a concrete procedural flow: preview first, then owner-approved confirm:true reusing the same requestId, and only claim live when status is active. This clarifies the confirmation gating condition. It does not, however, say when to prefer this over detach_ad_label, so exclusions are missing.

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