Stop Kimai Timesheet

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

Annotations indicate write operation (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds that it is a 'sensitive edit' requiring authorization and that 'the existing record is saved to a temp backup file before stopping,' which provides useful behavioral context beyond annotations.

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: first states purpose, second adds sensitivity and backup. It is concise and front-loaded, with no extra words. Could be slightly more structured, but effective.

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?

As a mutation tool without output schema, the description covers the action, authorization requirement, and backup behavior. It does not mention what happens if the timesheet is already stopped, but that is a minor gap. Overall adequate for the tool's complexity.

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 100%, so the description need not explain each parameter. However, it does not add parameter-specific meaning beyond the schema; e.g., the backup behavior is not tied to any parameter. Baseline 3 is appropriate.

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 starts with 'Stop an active Kimai timesheet,' clearly stating the verb ('Stop') and the resource ('active Kimai timesheet'). This distinguishes it from sibling tools like create, restart, or duplicate.

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 explicitly states 'Sensitive edit: call only after explicit human authorization,' providing clear when-to-use guidance. It also mentions backup behavior, but does not explicitly contrast with alternative actions (e.g., pause vs. stop), though the sibling list implies distinct purposes.

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