update_case_status

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

With no annotations provided, the description carries full burden for behavioral disclosure. It indicates this is a mutation tool ('update'), but doesn't mention permissions required, whether changes are reversible, side effects, rate limits, or what happens to existing data not mentioned. For a mutation tool with zero annotation coverage, this is a significant gap.

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, efficient sentence with zero wasted words. It's appropriately sized for a tool with good schema documentation and gets straight to the point without unnecessary elaboration.

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 5 parameters and no annotations or output schema, the description is inadequate. It doesn't explain what the tool returns, error conditions, or important behavioral aspects. While the schema covers parameter documentation well, the description fails to provide the contextual information needed for safe and effective use of this update 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 description coverage is 100%, so the schema already documents all 5 parameters thoroughly. The description adds minimal value beyond the schema—it mentions 'optional priority and assignment changes' which corresponds to the 'priority' and 'assignedTo' parameters, but doesn't provide additional context about their meaning or usage.

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 clearly states the verb ('update') and resource ('case status'), making the purpose understandable. However, it doesn't distinguish this tool from potential sibling tools that might also modify cases, as the sibling list provided doesn't include obvious alternatives for case status updates.

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 provides no guidance on when to use this tool versus alternatives, prerequisites, or constraints. While it mentions 'optional priority and assignment changes,' this doesn't constitute usage guidelines—it's just listing optional parameters without context about when they're appropriate.

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