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

Annotations already flag destructiveHint=true, openWorldHint=true, and idempotentHint=false, so the risk profile is known. The description adds genuinely new behavior: a two-step approval gate, requestId reuse for confirmation and recovery, and the caveat that the claim is only live once status is active. It stops short of saying what exactly is spent or how to poll status.

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?

The text is short and front-loads purpose before workflow, which is good. The trailing 'Fields: soclo://tools/soclo_ads_create_shared_budget' is a dangling self-referential URI with no explanation of how an agent should use it, and 'Claim live only when status is active' is compressed to the point of ambiguity.

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, money-moving operation with 10 parameters, a nested payload whose subfields carry no schema descriptions, and no output schema. The description leaves the preview step unidentified, does not explain the expected* verification parameters, and gives no way to learn the resulting budget status beyond an unexplained pointer.

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 explains the two most consequential parameters (confirm and requestId) with actual semantics rather than labels. It says nothing about the expectedCurrency/expectedBudgetType/expectedBudgetAmount cross-check group, the payload name/amount/type fields, or platform, leaving a meaningful share of the 10 params undocumented.

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 specific verb and resource ('Create a shared budget'), which is unambiguous against the only nearby sibling, soclo_ads_list_shared_budgets. It does not explicitly name that sibling or note that this tool also serves as its own preview step, so the differentiation is implicit rather than spelled out.

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?

The description gives a real workflow constraint: preview first, then owner-approved confirm:true reusing the same requestId. However, it never names the tool or call that produces the preview, gives no condition for when the budget should not be created, and offers no alternatives to soclo_ads_list_shared_budgets for inspection.

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