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

With no annotations, the description carries full responsibility for behavioral disclosure. It implies a write/mutation side effect ('Automate parcel booking') but does not explain whether authentication is required, whether existing records are affected, or what the response contains beyond 'instant tracking code'.

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 sentence, but it is not concisely informative—it omits critical details. Underspecification is not conciseness; the sentence lacks structure (e.g., no breakdown of steps, inputs, or outputs) and does not earn its place given the complexity of the tool.

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 tool with five parameters, zero schema descriptions, no annotations, and no output schema, the description is severely incomplete. It does not specify parameter formats, required fields, or expected behavior, making it impossible for an agent to call the tool reliably.

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 description coverage is 0%, so the description must explain the parameters. It fails to provide any meaning for 'note', 'codAmount', 'recipientName', etc. The description only mentions the general action, leaving agents without the necessary information to populate the five parameters correctly.

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 states a specific verb ('Automate'), a clear resource ('parcel booking with Steadfast courier'), and a distinct result ('instant tracking code'). It unambiguously identifies the tool's purpose and is not confused with any sibling, none of which relate to parcel booking.

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. It does not mention prerequisites, context, or exclusions. The description only states what it does, leaving the agent to infer when parcel booking is appropriate.

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