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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true. The description's 'Read only; no spend' merely restates that, adding no new behavioral context such as what the defaults cover, whether they are account-scoped or platform-dependent, or any auth/rate considerations.

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?

Very short and front-loaded, so nothing is wasted, but the trailing 'Fields: soclo://tools/soclo_ads_get_dsa_defaults.' is a bare self-referencing URI that conveys no actionable information and reads like a template artifact.

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?

No output schema exists, and the tool takes a nested object parameter plus a 'confirm'/'requestId' confirmation pair that the description never explains. Given that complexity, the description leaves too much for the agent to infer about inputs and expected results.

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?

Six parameters with only 50% schema description coverage, including an undocumented nested 'parameters' object and bare 'platform'/'accountId' fields. The description mentions no parameters at all, so the half-documented surface must be guessed by the agent.

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 ('Get ad account DSA defaults'), which is clearly distinct from writing/updating tools. It does not, however, distinguish itself from the closely-named sibling soclo_ads_get_dsa_recommendations, so an agent must infer the defaults-vs-recommendations split.

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?

There is no explicit when-to-use or when-not-to-use guidance. 'Read only; no spend' hints at a safe pre-flight read but never says under what circumstances an agent should call this versus soclo_ads_get_dsa_recommendations or the account-level listing tools.

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