ebay_update_keyword_bid

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

No annotations provided, so the description must disclose behavioral traits. It only states 'update', implying mutation, but does not mention permissions, rate limits, idempotency, or what happens if the keyword does not exist. This is insufficient for a mutation tool.

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 concise—one sentence. While front-loaded and efficient, it omits necessary details. Minimalism is not a virtue here; the description could be improved with context without becoming verbose.

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, but description does not mention return values. With nested bid object and campaign context, more detail is needed. The description is under-specified for the tool's complexity.

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%, so baseline is 3. The description adds no additional meaning beyond the schema. It does not clarify bid format, currency, or how to obtain campaignId/keywordId.

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 'Update the bid for a specific keyword' clearly states the verb (update), resource (bid), and scope (specific keyword). It effectively distinguishes from sibling tools like ebay_update_keyword (updates other attributes) and ebay_bulk_update_keyword_bids (bulk operation).

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. The description does not mention that this is for single keyword updates, nor does it reference the bulk counterpart ebay_bulk_update_keyword_bids. An agent would lack context for choosing the appropriate tool.

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