sellfox_ads_sb_target_hourly

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

No annotations exist, so the description carries full burden. It only labels the tool without disclosing any behavioral traits such as read-only status, data freshness, rate limits, or response structure. The single phrase provides no transparency beyond the name.

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 description is extremely short (one phrase), but it is under-specified rather than helpfully concise. It lacks essential information to guide an AI agent, making it insufficient for effective tool selection.

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?

With no output schema and a complex tool that returns hourly reporting data by targeting, the description is completely inadequate. It fails to explain the report's content, limitations, or how optional parameters affect 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?

Schema coverage is 100% with basic Chinese descriptions for each parameter. The tool description adds no additional meaning beyond what the schema already provides, so baseline score of 3 is appropriate.

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?

The description '小时报告-SB投放报告' (Hourly report - SB delivery report) clearly indicates this tool provides hourly reports for Sponsored Brands targeting. It distinguishes from sibling tools like sellfox_ads_sb_campaign_hourly (campaign-level) and sellfox_ads_sb_ad_group_hourly (ad group-level) by specifying 'target', though not explicitly stating it is for targeting entities.

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 usage guidance is provided. The description does not indicate when to use this tool instead of similar hourly report tools for campaigns, ad groups, or placements, nor does it mention any prerequisites or exclusions.

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