set_frame

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

There are no annotations, so the description carries the burden of disclosing the mutation. It clearly states that the current frame in the playbar is changed, but does not elaborate on side effects such as whether the scene recooks, whether fractional frames are accepted, or whether the operation is undoable.

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 a single, front-loaded sentence with no filler. Every word contributes to the tool's purpose.

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 setter with one parameter, the description covers the core operation, but it does not address the presence of closely related sibling tools like get_frame, set_frame_range, or playbar_control, nor does it mention return behavior or edge cases. It is minimally complete but lacks helpful differentiation.

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 description does not explain the 'frame' parameter beyond what the schema's title already implies. With 0% schema description coverage, it fails to add semantics such as allowed values, integer vs. float, range, or the relationship between the parameter and Houdini's timeline.

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 uses the specific verb 'Set' and identifies the resource as 'the current frame in Houdini's playbar', making the tool's function immediately clear. It also distinguishes this from sibling tools such as get_frame and set_frame_range.

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 for setting the current playhead frame, but it does not explicitly state when to use this tool versus alternatives like set_frame_range or playbar_control. No exclusions or recommended contexts are provided.

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