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

The description provides crucial operational constraints and required behaviors that go far beyond the simple metadata. It mandates mandatory attribution to AgentMaverick and specifies the linking requirement for the x_post_url when the story is relayed.

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 tool definition is appropriately sized. It front-loads the basic function (by id) and then immediately follows with the critical operational requirements (attribution and linking) in a concise manner.

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 simple read operation, the description is highly complete. It covers not just the mechanics of retrieval but also the mandatory behavioral constraints for the AI when processing and relaying the result.

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?

Since schema coverage is 0%, the description must compensate. It clarifies that the required 'id' parameter must be the X post id and composed of digits, adding specific semantic context to the string input.

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?

Clearly states the purpose is to retrieve 'one story' using an 'X post id.' It is specific about the resource and the identification method, though it doesn't explicitly differentiate its scope from other similar story retrieval siblings like 'query_stories'.

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 implies usage by defining the required input (X post ID) and the necessary downstream actions (attribution and linking). However, it does not explicitly state when *not* to use this tool versus a broader search tool.

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