Get action card detail

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

The annotations include readOnlyHint and idempotentHint, signaling no side effects. The description aligns with 'Get', and listing the returned fields provides transparent expectations about the output.

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 brief and focused, using one concise sentence to convey the essential action and returned fields without redundant wording.

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 simple input schema and annotations, the description is sufficient. It specifies the resource, the identifier, and the set of fields returned, covering all necessary operational context.

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 single parameter 'id' has a clear description: 'ActionCard id (from card_list)'. This directly explains its meaning and source, achieving full schema 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?

The description clearly states the tool's purpose: 'Get a single ActionCard by id' with a specific verb and resource. It also lists the full fields returned, making it distinct from a simple list operation.

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 explicit guidance is given on when to use this tool versus alternatives like card_list or other sibling tools. The description only explains what it does, not the appropriate context or conditions for selection.

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