get_time_entry

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

With no annotations, the description carries full burden for behavioral disclosure, but it only states the basic function. It does not mention that this is a read-only operation, how errors are handled (e.g., invalid ID), or any authentication/permission requirements.

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 with no extraneous content. It is front-loaded with the core purpose and is highly efficient.

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 tool's simplicity (single required parameter, output schema available), the description is largely sufficient. It could be slightly improved by noting that the response contains the full time entry object, but the output schema covers that. The description adequately covers the essential need.

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 schema provides no description for the parameter (0% coverage). The description adds the detail that the ID is a GUID, which clarifies the expected format beyond the schema's type string. However, it does not explain the origin or validation of the ID.

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 'Get a time entry by ID (GUID)' clearly states the action (Get), the resource (time entry), and the identifier method (GUID). It distinguishes this from sibling tools like list_time_entries (which returns multiple) and get_time_entry_lookups (which return reference data).

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 such as list_time_entries or get_time_entry_lookups. There is no mention of prerequisites (e.g., needing a valid GUID) or situations where this tool is preferred.

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