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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is known. The description adds real context beyond that: creation requires a spend preview followed by an owner-approved confirm flag reusing the same requestId, and the result should only be treated as live once status is active. It does not explain rollback or what happens to the conversion action if confirmation is skipped.

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?

Purpose is front-loaded and the approval workflow follows in one compact sentence, but the trailing 'Fields: soclo://tools/...' reference is a dangling pointer with no usable content, and 'Claim live only when status is active' is telegraphic without naming how status is obtained.

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, open-world, 10-parameter tool with a nested payload and no output schema, the description covers the approval/safety path but omits how to source adAccountId/accountId, what the nested payload fields mean, and which tool verifies the resulting status (soclo_ads_operation_status). Adequate minimum, but with clear gaps.

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?

Coverage is 60% and the description only touches confirm and requestId, largely restating the schema text for those fields, though it does add the useful constraint that the requestId must match the previewed request. The nested payload object (name, type, category, countingType, lookback windows, etc.) has no documented semantics in either the description or the schema, so the description does not compensate for that 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?

The description pairs a specific verb and resource ('Create website conversion action') under the Soclo Ads namespace, which lets an agent distinguish it from soclo_ads_update_conversion_action and soclo_ads_list_conversion_actions by name. It stops short of explicitly stating how it differs from the sibling create_custom_conversion_goal, so no credit for active sibling differentiation.

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?

It does state a prerequisite workflow for this tool: preview first, then confirm:true with owner approval and the same requestId. However it never says when to choose this over soclo_ads_update_conversion_action or soclo_ads_create_custom_conversion_goal, nor which platforms/ad accounts qualify.

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