ebay_bulk_update_campaign_keyword

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

No annotations provided, so the description carries full burden. It only states 'Bulk update keywords' without disclosing whether the update is partial or full replacement, required permissions, side effects, or error handling. This is insufficient.

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 a single sentence, which is concise, but it is too terse and lacks essential context such as what fields can be updated or behavior on success. It is not overly verbose, but it sacrifices completeness for brevity.

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 the complexity (nested bulk update, 2 required params, no output schema), the description is incomplete. It does not explain return values, error conditions, or whether the operation is additive or replacement. The context from siblings does not compensate.

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% with descriptions for all parameters, so baseline is 3. The description adds no additional meaning beyond what the schema provides (e.g., it does not clarify update semantics like partial vs full update).

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 clearly states the verb (bulk update) and resource (keywords at the campaign level). It distinguishes from siblings like 'ebay_bulk_create_campaign_keyword' (create vs update) and 'ebay_bulk_update_campaign_negative_keywords' (negative vs regular keywords), though it does not explicitly list alternatives.

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 tool versus alternatives such as 'ebay_update_keyword' (single update) or 'ebay_bulk_update_campaign_negative_keywords'. It does not specify scenarios, constraints, or prerequisites.

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