Finish locker session

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It only says 'End' and 'tear it down' without detailing side effects like whether the locker is released, whether the session is irrevocably closed, or what errors may occur. It lacks information about permissions or idempotency.

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?

Two sentences, front-loaded with the main action. The second sentence provides a crucial reference to the open tool without unnecessary fluff. Every word earns its place.

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?

Without an output schema, the description does not explain what the tool returns (e.g., success indicator). It also does not elaborate on the 'tear it down' scenario or the conditional phoneNumbers parameter. However, given only two params and a simple finish operation, it is minimally adequate.

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 100%, so the schema already documents both parameters. The description adds a useful note that the session id comes from inpost_consumer_locker_open, reinforcing but not significantly extending schema meaning.

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 uses the specific verb 'End' with the resource 'Paczkomat pickup session', clearly identifying the action and scope. It also distinguishes itself from siblings by referencing the session id from inpost_consumer_locker_open, making it the explicit counterpart to the open tool.

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?

It explicitly states when to use the tool: after opening a session or for teardown. It links to the workflow by instructing to use the session id returned by inpost_consumer_locker_open. No explicit exclusions or alternatives are given, but the context is clear.

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