update_case_stage

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

No annotations are present, placing the full burden on the description. The description only states the action without disclosing side effects, permissions, reversibility, or any behavioral traits beyond the basic rename operation.

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 very concise (one sentence) with no wasted words, but it lacks structure and essential information, making it under-specified rather than efficiently concise.

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 the tool's simplicity and the presence of an output schema, the description is still incomplete. It fails to explain the operation's effects, error conditions, or how it fits within the case management workflow.

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%, and the description does not add any meaning to the parameters (stage_id, name) beyond their names. The tool's purpose implies renaming, but no extra context is provided for correct parameter 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 'Rename a case stage' uses a specific verb (rename) and resource (case stage), clearly stating the tool's function. However, it does not differentiate from sibling tools like 'create_case_stage' or 'delete_case_stage', preventing a perfect score.

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, lacks context or exclusions, and does not mention any prerequisites or typical scenarios.

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