team_time_complete_task

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, and the description adds real context beyond them: an atomic side effect on the key creator's running timer, and the failure mode where other members' timers block completion. The one notable omission is any mention of the expectedVersion optimistic-concurrency check, despite the tool being non-idempotent.

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?

Three short sentences, front-loaded with the action, then the parameter rule, then the side effect. Dense and mostly waste-free, though "Complete verified work" is slightly jargon-laden.

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 destructive, non-idempotent mutation with no output schema and 0% schema coverage, the description covers side effects and the claimId rule but leaves the mandatory expectedVersion semantics and the result payload shape unexplained. Adequate, but not enough to invoke confidently on the first try.

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 0%, so the description must carry parameter meaning and it largely does not. It clarifies claimId's conditional role, but says nothing about expectedVersion (optimistic concurrency token) or taskId, and "test evidence and relevant links" do not map to any schema field — only `result` exists, so it is unclear where that content goes.

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?

States a specific verb+resource ("Complete ... work", i.e. a task) and adds scope: record outcome, test evidence, links. An agent can tell this is the completion action rather than a generic edit. However, it never names team_time_set_status or team_time_update_task and why completion is a distinct operation from setting status.

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?

"Include claimId for claimed work" is a genuine conditional rule that tells the agent when a parameter is required. Beyond that there is no when-to-use / when-not-to-use guidance, no prerequisites (e.g. must the task be claimed first?), and no differentiation from the sibling status/update tools.

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