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

Annotations already flag destructiveHint=true, idempotentHint=false, and openWorldHint=true, but the description goes further by disclosing the preview/owner-approval gate and the requestId-reuse contract needed to recover an outcome. That is genuinely useful context an agent cannot get from the annotations. It still doesn't say precisely what is destructive here or how to recover via soclo_ads_operation_status, which keeps it off a 5.

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?

It is short and front-loads the safety protocol, which is the right ordering. However, the trailing fragment "Fields: soclo://tools/soclo_ads_create_test_lead." is an opaque pointer with no explanation of what to do with it, and "Claim live only when status is active" is ambiguous about whose status. Compression here edges into under-specification.

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?

This is a destructive, open-world, 10-parameter tool with nested payload objects, no output schema, and only 60% parameter documentation. The description covers the approval mechanics but leaves the entire payload shape, the formId/platform/adAccountId relationship, and the return/recovery path unaddressed — not enough for an agent to call it correctly on the first try.

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 60%, so the baseline is 3. The description does reinforce that confirm and requestId must be paired with a prior preview, which corroborates the schema's own descriptions, but the semantic core — payload.fieldData name/values pairs, parameters.formId, platform, adAccountId, and the expected* preview-echo fields — gets no treatment at all.

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 first sentence, "Soclo Ads: Create a test lead," is a verbatim restatement of the tool title, so an agent learns nothing beyond the name. It never explains what a "test lead" is (presumably a synthetic submission used to validate a lead form) or how it differs from siblings like soclo_ads_create_lead_form or soclo_ads_list_leads. The verb+resource are identifiable, but the definition adds no differentiating substance.

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 encode a real two-step protocol: preview first, then a confirm:true call with the same requestId after owner approval, and it implies the claim only goes live once status is active. What it never states is when to reach for this tool versus creating a real lead form submission, or when not to use it at all. Usage is implied through the approval flow rather than framed as selection guidance.

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