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

The description meaningfully supplements the annotations by disclosing the preview-then-owner-approved-confirm gate and the requestId reuse contract, which the destructiveHint/non-idempotent annotations alone do not convey. The phrase 'Claim live only when status is active' is murky, but the safety workflow context is a real addition.

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 action, but the trailing 'Fields: soclo://tools/soclo_ads_reply_to_ad_comment' is cryptic filler that does not inform invocation. The confirm-workflow sentence, while dense, earns its place.

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, no-output-schema tool, the description covers the confirmation flow but leaves the budget-related parameters and the reply payload unexplained. It is enough to avoid an unsafe call but not enough to invoke confidently for the odd budget fields.

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 schema carries part of the load. The description clarifies requestId and confirm semantics but says nothing about payload.text, adId/commentId, platform, or the surprising expectedCurrency/expectedBudgetAmount/expectedBudgetType fields, leaving notable ambiguity unexplained.

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 ('Reply to an ad comment'), which is clear enough to distinguish from generic tools. However, it does not differentiate from adjacent siblings like soclo_inbox_reply_comment or soclo_ads_get_ad_comments, so the agent must infer the ad-context scoping.

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 workflow guidance for the confirm/requestId preview protocol ('preview, then owner-approved confirm:true with the same requestId'), which is useful. But it never says when to choose this versus the inbox reply tools, nor any exclusions, so selection guidance is only implied.

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