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

No annotations are provided, so the description carries the full burden. It does not say whether the change is idempotent, whether it notifies assignees, whether it works on completed/blocked tasks, or what the response contains — significant gaps for a mutation tool with zero annotation coverage.

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, and the operation is stated first. Its brevity is appropriate, though the terseness borders on under-specification given the missing behavioral details.

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 mutation tool with no annotations and no output schema, the definition leaves too much open: side effects, permission requirements, and the distinction from taskhold_update are all unstated. The schema alone cannot convey those traits.

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% and both parameters are documented with a UUID pattern and a four-value enum, so the description needs to add little. It adds nothing beyond the schema, which is the correct baseline at full coverage.

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 (change) and resource attribute (a task's priority), so the operation is unambiguous on its own. It does not, however, distinguish itself from the sibling taskhold_update, which plausibly also touches priority.

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?

No guidance on when to use this versus taskhold_update (the obvious overlapping sibling), and no prerequisites mentioned such as task existing, being open, or permission to reprioritize. The agent must infer everything about selection conditions.

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