set_sculpt_brush

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

With no annotations, the description carries the full burden. It only says 'configure active sculpt brush,' implying modification of brush properties but not disclosing whether it changes the active brush selection, requires an active brush, or has side effects. It does not mention error conditions or return behavior.

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 sentence, but this is under-specification rather than conciseness. It lacks necessary details about parameters and constraints, so the brevity does not serve the agent's needs.

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 tool with three parameters and no structural information about them, the description is incomplete. It does not cover what the parameters control, what the output schema returns, or any setup steps. The agent cannot confidently invoke this 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 coverage is 0% and the description mentions none of the parameters. 'Configure' gives no indication what size, strength, and brush_name do. The agent must guess at semantics from the parameter names alone, which is insufficient.

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 states a specific verb ('Configure') and resource ('active sculpt brush'), distinguishing it from other sculpt-related tools like enter_sculpt_mode or list_brushes. However, it is vague about what 'configure' entails, leaving the exact operation unclear.

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 gives no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., entering sculpt mode), nor does it contrast with other brush-setting methods. The agent must infer usage from the name alone.

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