Manifest / Book Consignments with Carrier

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

Annotations already indicate write (readOnlyHint false) and non-idempotent. The description adds key effects: creates pickup booking and generates tracking numbers. However, it does not disclose that the operation may fail if carrier is unavailable, potential side effects, or that it is not idempotent. Given annotations cover some safety, the description adds moderate value.

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: two sentences and an Args section. It front-loads the main action. However, it could be more structured by listing effects or prerequisites in bullet points. Nonetheless, it is efficient and clear.

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 one parameter and no output schema, the description covers the primary purpose and parameter. However, it omits return value (e.g., tracking numbers, manifest ID) and error handling. It is acceptable for a simple tool but lacks completeness for a workflow step.

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?

There is one parameter with 100% schema description coverage. The description repeats the schema's explanation ('Array of booked manifest objects with consignment IDs and carrier booking details') but does not add new constraints or examples. It minimally adds meaning beyond the schema.

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 'Books/manifests' and the resource 'consignments with the carrier', and explains it creates pickup booking and generates tracking numbers. It also explicitly positions it as 'the final step in the consignment workflow', distinguishing it from sibling tools like create_consignment or get_consignments.

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 description implies usage as the final step but does not explicitly state prerequisites (e.g., consignments must be created first) or when not to use it. It also lacks guidance on alternatives or consequences of multiple calls (non-idempotent). The context is partially clear but not thorough.

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