List Reddit ad accounts

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

Annotations already declare readOnlyHint and destructiveHint, so safety is covered. The description adds useful behavioral context by naming the output fields (ad_account_id, currency, time zone, approval state) and the connection requirement, going beyond the annotations.

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?

Two concise, front-loaded sentences. The first states the core purpose; the second gives actionable guidance about ordering and connection prerequisites. No filler or redundancy.

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?

Given zero parameters, existing annotations, and an output schema, the description fully covers what an agent needs: purpose, when to call it, prerequisites, and key output values. Nothing essential is missing.

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?

The tool has zero parameters, so there are no parameter semantics to explain. The description does not waste space on parameters and the schema coverage is effectively complete.

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 the specific action 'List' and the resource 'Reddit businesses and ad accounts the connected Reddit user can access.' It also clarifies the primary purpose: discovering ad_account_id values needed by other Reddit tools, which clearly differentiates it from siblings like list_reddit_funding_instruments and get_reddit_campaigns.

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?

Explicitly instructs to 'Call first' before using other Reddit tools and gives the prerequisite connection setup steps. This tells an agent exactly when to invoke this tool and what environment must be in place.

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