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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description adds that a reason is required ("with a reason") but says nothing about whether the dismissal is reversible, how it affects downstream status, or what happens to the task afterward.

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?

A single front-loaded sentence with no filler; the action and the key input requirement are both stated immediately.

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-read-only mutation with no output schema, the description is minimal: it does not explain the post-dismissal state, reversibility, or how the task differs from a resolved one. It is adequate but leaves meaningful gaps for an irreversible operation.

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 67%; the id and project params are self-documented, and the description's "with a reason" supplies the missing meaning for the undocumented note parameter. It adds useful semantics beyond the raw schema, though it doesn't clarify format expectations for note.

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 ("dismiss a manager task") that maps clearly onto the tool name. It does not explicitly contrast with the semantically close siblings resolve_manager_task and reopen_manager_task, so an agent must infer the difference between dismissing and resolving.

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?

"that no longer applies" gives an implied when-to-use condition, but there is no explicit guidance on when to dismiss versus resolve/reopen a task, nor any prerequisites. Usage is left to inference.

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