wwa_handoff_verify

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

With no annotations, the description carries the burden of behavioral disclosure. It explains that the tool validates structure, required fields, and completeness, and it highlights the benefit of preventing context loss. However, it does not disclose whether the operation is read-only, what the return value or error behavior looks like, or any side effects.

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 concise and front-loaded, with each sentence contributing value. The first sentence states the core purpose, the second specifies what is validated, and the third explains the consequence. There is no wasted wording.

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?

The tool has one parameter with schema descriptions, but no output schema or annotations. The description explains what the tool validates and why, but it does not describe the return value or outcome of verification, nor does it contrast the tool with closely related siblings like wwa_handoff_validate_schema. This leaves gaps for an agent deciding whether to use this tool and interpreting 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?

The input schema already provides a complete description of the 'handoff' parameter with 100% coverage. The tool description adds no additional meaning about the parameter beyond stating it is the handoff document to verify, so a 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 clearly states the tool verifies a handoff document before accepting it, specifying the action (verify), resource (handoff document), and context (before accepting). However, it does not explicitly distinguish itself from the sibling tool wwa_handoff_validate_schema, which likely has overlapping validation responsibilities.

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?

The phrase 'before accepting it' provides clear context for when to use the tool: when an agent is about to accept a handoff document. While it does not mention alternatives or exclusions, this timing guidance is explicit enough to guide appropriate usage.

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