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

No annotations are present, so the description must carry the full behavioral burden. It does disclose strict joint-angle limit enforcement and a USDC fee on Base L2, but it is silent on convergence behavior, failure modes, return format, or whether computation is stateless.

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 compact: one sentence packs the algorithm, target resource, and key behavioral constraint, and a second sentence gives the cost. Every phrase earns its place with no redundant filler.

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 complex 6-DOF IK solver with no output schema and no annotations, this description is too thin. It does not explain how to construct the payload, what the solver returns, what units are used, or when the solver might fail, so an agent cannot confidently invoke 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?

Schema description coverage is 100%, so the baseline is 3. However, the payload description is generic ('Input parameters or JSON string payload') and the tool description adds no detail about what the payload should contain, such as target end-effector pose, joint limits, or robot geometry.

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 identifies the tool as a CCD/FABRIK solver that computes joint angles for a 6-DOF robotic manipulator. It names the specific algorithms, the subject domain (robotics), and the output (joint angles), which distinguishes it from all unrelated sibling tools.

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 say when to use this tool versus alternatives, nor does it provide expected inputs, prerequisites, or exclusions. The only usage hint is the tool's name and the generic 'solver' language, which is not enough guidance for an agent deciding between tools.

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