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

Annotations already flag destructive, idempotent and open-world behavior, so the description's incremental value is the two-phase safety protocol (preview, then owner-approved confirm:true, reusing the same requestId) and the note that claims only go live when status is active. These add genuine operational context beyond the annotations, though "Claim live only when status is active" is vague and no return/outcome format is given.

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 the confirmation constraint is front-loaded, but the closing "Fields: soclo://tools/soclo_ads_update_campaign_assets." doesn't earn its place and the "Claim live only when status is active" sentence is opaque. Some telegraphic fragments cost clarity more than they save space.

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, 10-parameter mutation with nested asset objects and no output schema, the description covers the critical preview/confirm gate but leaves the nature of the asset updates and the budget-verification fields unexplained. It is minimally adequate but not complete enough for an agent to call it confidently without reading the schema closely.

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%, and the description adds no parameter meaning beyond what the schema already documents (confirm and requestId reuse are both spelled out in schema descriptions). The nested payload structure (updates with assetResourceName, sitelinkAsset, calloutAsset, structuredSnippetAsset) and the expectedBudget/expectedCurrency guard fields are untouched, and the "Fields:" URI replaces explanation rather than providing it.

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 restates the title ("Soclo Ads: Update campaign assets") without much expansion. It states a verb and resource, so the basic purpose is identifiable, but it doesn't distinguish from near-identical siblings such as soclo_ads_attach_campaign_assets, soclo_ads_remove_campaign_assets, or soclo_ads_update_ad_group_assets. The trailing "Fields: soclo://tools/..." URI is a pointer, not a purpose statement.

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 gives a concrete workflow cue: spending/deletion requires a preview first, then an owner-approved confirm:true with the same requestId. That is real usage guidance for the confirmation path, but it says nothing about when to choose this tool over attach/remove/update alternatives, and no prerequisites for the initial (preview) call are stated.

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