download_delivery_note_pdf

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description's 'Gets pdf' aligns with a safe read operation. However, the description adds no extra behavioral context, such as how the PDF is returned (binary vs URL), what happens on error, or whether any side effects occur.

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 short sentence with no fluff. It is front-loaded with the key action and resource. However, it could be slightly more informative without increasing length, e.g., mentioning the output format.

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 low complexity (1 param, no output schema, annotations present), the description is adequate but not complete. It fails to mention the return type (PDF binary) or error scenarios, which would be helpful for an agent.

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 covers the single parameter 'delivery_note_id' with description 'delivery note ID' (100% coverage). The tool description adds no additional meaning beyond the schema, so the baseline score of 3 applies.

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 'Gets pdf of specified delivery note' clearly identifies the action (get) and resource (pdf of delivery note). It distinguishes from sibling download tools for other document types (e.g., download_invoice_pdf) by specifying 'delivery note', but does not explicitly differentiate its purpose beyond the tool name.

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 usage guidance is provided. The description does not indicate when to use this tool versus alternatives like download_invoice_pdf or send_delivery_note_by_email. There are no conditions, prerequisites, or exclusions mentioned.

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