get_case_action

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

No annotations are provided, so the description must carry the full burden. It only states "Get detailed information" without disclosing side effects, authentication dependencies (beyond sessionCredentials parameter), rate limits, or any operational constraints. The add of "view metadata and available actions" is minimal behavioral context.

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, front-loaded sentence that states the tool's purpose without any wasted words. It efficiently conveys the core function and key information returned.

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 read-only retrieval tool with 5 parameters (including a nested sessionCredentials object), the description together with the schema covers the essential aspects. It mentions the key elements of the response (view metadata, available actions). However, the absence of an output schema could have been mitigated by a brief description of the return structure, which is not provided.

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?

The input schema has 100% coverage with detailed descriptions for all parameters, including examples for caseID and actionID. The description adds no further meaning beyond the schema, but given the high coverage, a baseline score of 3 is appropriate.

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 "Get" and the resource "case action", and specifies what information is returned: "detailed information, including view metadata and available actions". This distinguishes it from sibling tools like get_case (case-level) and get_assignment_action (assignment actions), making the purpose specific and actionable.

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 does not provide any guidance on when to use this tool versus its many siblings (e.g., get_case, get_assignment_action, perform_case_action). There is no mention of prerequisites, contextual conditions, or when to choose an alternative, leaving the agent without clear decision criteria.

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