Update a time entry

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

The description is minimal and does not disclose any behavioral traits beyond the basic update action. No annotations are provided, so the description carries the full burden. It does not mention side effects, authentication requirements, error conditions, or what happens if the entry does not exist.

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 very short and to the point, but it lacks important details. It is concise in length but not in completeness, as it omits necessary context. The front-loading is acceptable (action and endpoint first).

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 complexity of two nested objects in the input schema and no output schema, the description is incomplete. It does not explain the expected behavior, return values, or how the update affects the resource. The presence of sibling create/delete tools without differentiation further reduces completeness.

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 description adds no meaning beyond the input schema. It only mentions 'Body: application/json' but does not explain any parameters. The schema itself provides descriptions for some properties (date, duration, isOvertime), but with 0% schema description coverage reported, the description fails to compensate for any gaps.

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 verb 'Update' and the resource 'a time entry', and includes the HTTP method and endpoint. This distinguishes it from related sibling tools like create and delete time entries. However, it does not elaborate on what specific fields can be updated, which would further clarify purpose.

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. There is no mention of prerequisites, context, or when not to use it. The description only explains what it does without any usage context.

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