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

With no annotations, the description carries the full burden. It discloses the operation (listing) and the nature of results (field names and values), but does not explicitly state it is read-only, how sorting is determined beyond 'letzten', or any limitations like pagination. This is reasonable but not exhaustive.

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 concise sentence that directly states the tool's purpose and output content. Every word is informative, with no fluff or repetition.

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 simple list operation with two parameters and no output schema, the description adequately covers the tool's purpose and result format. It could mention ordering or default limit, but the schema provides limit details, and 'letzten' hints at the ordering.

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 coverage is 50%, with 'limit' already described in the schema and 'tracker_id' self-explanatory. The description does not add any additional parameter-specific detail, but the schema plus the tool name are sufficient for the two simple parameters.

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 action ('Listet'), the resource ('Eintraege eines Trackers'), and adds the scope ('letzten' meaning latest) plus output content ('mit Feldnamen und Werten'). This distinguishes it from siblings like list_trackers and list_boards, which target different resources.

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 the tool is for listing entries of a tracker, and the mention of 'letzten' indicates it returns recent entries. However, it provides no explicit guidance on when to use this over alternatives, nor does it mention exclusions or prerequisites.

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