constraints.set

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

With no annotations provided, the description must fully disclose behavioral traits. It only states that it sets a property, but omits critical details like whether the operation is idempotent, what happens if the constraint doesn't exist, or any side effects. This is insufficient for safe invocation.

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 very short (one sentence), which is concise but may be too minimal given the tool's complexity (6 parameters). It lacks structure such as front-loading key information or breaking down usage. It does not waste words but also does not fully inform.

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 tool's complexity (6 parameters, no output schema, no annotations), the description is incomplete. It fails to explain how RNA property identifiers work, error scenarios, or the relationship between 'owner', 'bone', and 'object'. This leaves the agent underinformed.

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 0%, so the description should compensate by explaining parameter usage. However, it adds no meaning beyond the schema titles. For example, it does not describe how to specify the 'owner' or 'bone' parameter, or the format of 'value' (JSON) beyond the schema hint.

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 specifies the action ('Set'), the resource ('one RNA property'), and the target ('object or pose-bone constraint'). It effectively distinguishes the tool from its siblings (constraints.list, constraints.add, constraints.remove, constraints.report) by highlighting that it performs a property update.

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 explicit guidance on when to use this tool versus alternatives like constraints.add or constraints.remove. It lacks any mention of prerequisites, limitations, or context that would help an agent choose the appropriate tool.

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