Update ad account

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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: it does not say whether this is a partial (merge) or full replacement update, whether omitted fields are preserved, or that it affects a single account addressed by ad_account_id.

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?

A single four-word sentence, front-loaded with verb and resource, with zero filler. It is concise but arguably under-specified rather than optimally structured.

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 mutation tool, the critical missing piece is update semantics (partial vs. full replacement) and confirmation that only one account is mutated. Rich schema coverage and non-destructive annotations compensate somewhat, but a mutation endpoint should do more than restate its own name.

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 description coverage is 100% and the nested `data` object enumerates every updatable field with enums inline, so the schema does the heavy lifting. The description adds no syntax or format meaning beyond it, which is the baseline-3 case.

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 (Update) and resource (ad account settings), which is enough to distinguish it from update_campaign, update_business, etc. by resource type. However, it offers no explicit sibling differentiation or scope detail beyond the two-word object.

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?

No guidance on when to use this versus reddit_ads_get_ad_account or the generic reddit_ads_api_request, and no prerequisites (e.g., required permissions or the need to know the account ID first). The agent must infer everything.

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