set_visual_baseline

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

No annotations provided, and the description omits behavioral traits such as whether it overwrites existing baselines, requires authentication, or has side effects. The description is too sparse to inform safe usage.

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?

Single sentence that is direct and front-loaded. Could be slightly more informative, but no wasted words.

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?

The description is incomplete for a tool with two parameters and no output schema. It does not explain return values, error conditions, or how the baseline is stored. Sibling tools are complex, making this lack of detail notable.

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 100%, and both parameters have clear descriptions. The tool description adds no additional meaning beyond the schema, so baseline score of 3 is appropriate.

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 states the action ('Set or update') and the resource ('visual baseline') with a specific purpose ('for future comparisons'). It distinguishes this tool from siblings like 'assert_visual_match' or 'compare_screenshots'.

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 on when to use this tool versus alternatives (e.g., 'record_visual_regression'). No prerequisites or contexts provided.

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