ebay_cancel_bundle

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

The description implies a mutation (cancel) but does not disclose behavioral traits like side effects, authorization requirements, or irreversibility. No annotations exist to compensate, so the description carries the full burden and falls short.

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, concise sentence that front-loads the action and key input. It is appropriately short, but could include more details without being 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?

For a cancellation tool with one parameter and no output schema, the description should mention prerequisites, expected effects, and return behavior. It does not, leaving significant gaps for an AI agent to safely use the tool.

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?

With 0% schema description coverage, the description must add meaning to the single parameter 'bundleId'. It merely restates 'by ID', adding no semantic value. The parameter type and format remain unclear.

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 'Cancel a bundle by ID' clearly states the action (cancel) and resource (bundle). It distinguishes from sibling tools like ebay_cancel_package by specifying 'bundle' rather than 'package', but could be clearer about what 'bundle' means in context (e.g., shipping bundle or order bundle).

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 is provided on when to use this tool versus alternatives like ebay_bulk_cancel_packages or when cancellation is appropriate. The description lacks prerequisites, such as whether the bundle must be in a cancellable state.

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