rollback_task

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action (rollback to a timestamp) but does not disclose whether the rollback is destructive, whether it creates a new version or overwrites, if it is reversible, or what consequences occur for states after the target timestamp. This lack of side-effect information is a significant gap for a mutation tool.

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, front-loaded sentence that states the action and key qualifier. It is concise and free of redundant information, achieving maximum efficiency.

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 that rollback is a potentially destructive operation with no output schema and no annotations, the description is under-specified. It does not explain the meaning of 'previous state', whether the rollback is a soft/hard revert, or how the timestamp is validated. More behavioral context is needed for an agent to use it safely, especially since sibling tools like get_task_snapshot and get_task_history exist for related non-destructive actions.

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 already covers both parameters with clear descriptions (taskId and targetTimestamp with ISO 8601 format). The tool description adds no further semantic meaning beyond what the schema provides, and with 100% schema coverage, the baseline of 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 uses a specific verb 'rollback' with a clear resource 'task' and qualifies it with 'to a previous state at a specific timestamp'. This precisely distinguishes it from sibling tools like update_task or delete_task by indicating a restore-to-timestamp operation.

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 implies usage for reverting a task to an earlier state, but it provides no explicit guidance on when to use this tool versus alternatives like update_task or get_task_snapshot. There are no exclusions or alternative recommendations, so the usage context is only implied.

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