everhour_update_time_record

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the update is partial or full, what happens when the record doesn't exist, whether any fields are required beyond 'id', or any permission/error considerations. The only behavioral detail is the time format flexibility, which is minor.

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 two sentences, immediately front-loaded with the core action, and contains no filler or redundant information. Every sentence contributes useful context.

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?

The schema covers parameter definitions well, but the description lacks behavioral context (e.g., return value, error handling, update semantics). With no output schema and no annotations, this is a clear gap. The description is adequate for basic invocation but not fully self-sufficient.

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 all parameter meanings. The description adds marginal value by explicitly highlighting the dual time format ('seconds or human-readable'), but this is also present in the schema. No unique parameter semantics beyond the schema are provided.

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 specifies the action ('Update') and the resource ('existing time record in Everhour'), which distinguishes it from sibling tools like create, delete, get, and list time records. The added note about time formats is a helpful extra detail.

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?

Usage is only implied by the verb 'update' and the presence of sibling time-record tools. There is no explicit guidance on when to choose this over alternatives (e.g., create vs. update) or any exclusions/prerequisites. However, the name makes the primary use case obvious.

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