listJoints

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

No annotations are provided, so the description carries full burden. 'List all Joints' implies a read operation but doesn't disclose behavioral traits like pagination behavior, rate limits, authentication requirements, or what 'all' means in practice (e.g., scope limitations). It mentions no side effects or safety considerations.

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 at just three words, with no wasted text. However, this brevity comes at the cost of being under-specified rather than efficiently informative. It's front-loaded but lacks substance.

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 no annotations and no output schema, the description is incomplete. It doesn't explain what a Joint is, what the output format looks like, or any behavioral context. For a tool with 4 parameters and complex sibling relationships, this minimal description leaves significant gaps.

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 100%, so the schema fully documents all 4 parameters. The description adds no parameter semantics beyond what's in the schema. Baseline 3 is appropriate since the schema does the heavy lifting, but the description provides no additional context about parameter usage or interactions.

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 'List all Joints' restates the tool name 'listJoints' almost verbatim, making it a tautology. It specifies the verb 'List' and resource 'Joints', but doesn't clarify what Joints are in this context or how this differs from sibling tools like 'getJoints' or 'createJoints'.

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 is provided on when to use this tool versus alternatives. There's no mention of prerequisites, when to choose listJoints over getJoints, or any contextual constraints. The description offers zero usage direction.

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