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

No annotations are provided, so the description carries full burden. 'Update case status' implies a mutation operation but gives no behavioral details about permissions needed, side effects, rate limits, or what 'status' means. The description contradicts the tool name ('create' vs 'update'), creating confusion about whether this creates or updates.

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 extremely concise (two words) but under-specified rather than efficiently informative. It wastes no words but fails to provide necessary context, making it more of an incomplete placeholder than a well-structured description.

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, no output schema, and ambiguous purpose, the description is completely inadequate. It doesn't explain what 'case status' refers to, what values are possible, or what the operation actually does, leaving the agent with insufficient information to use the tool correctly.

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?

With 0 parameters and 100% schema description coverage, the baseline is 4. The description doesn't need to explain parameters since none exist, though it could mention that no inputs are required.

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 'Update case status' restates the tool name 'create_case_status' with a different verb ('update' vs 'create'), creating confusion rather than clarifying purpose. It doesn't specify what resource is being updated or distinguish from sibling tools like 'create_case_archive', 'create_case_assign', or 'create_cases'.

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 tool versus alternatives. The description provides no context about prerequisites, appropriate scenarios, or distinctions from related case management tools in the sibling list.

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