sensor_visual

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

No annotations are provided, and the description offers zero behavioral disclosure. It does not mention side effects, data formats, return values, or any operational context, leaving the tool's runtime behavior completely opaque.

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 extremely terse (one phrase), but this is under-specification rather than effective conciseness. It does not use the space to convey meaningful content, and the lack of structure (no sentences, no guidance) makes it essentially a title.

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?

With no annotations, no output schema, and a description that only repeats the tool's topic, the tool is drastically underdescribed. It fails to explain what the tool does, what inputs mean (beyond schema), or what results to expect, making it unusable for correct invocation.

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%, as every parameter (input, videoFrames, width, height, source, channels, simulate) has a description in the schema. The baseline of 3 is appropriate because the description adds no parameter information, but the schema already documents all parameters.

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 'V-JEPA 2 Visual Encoding (Image/Video)' is a noun phrase, not a statement of what the tool does. It lacks an action verb and merely restates a topic related to the tool name 'sensor_visual', providing no clarity on the tool's actual function.

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?

There is no guidance on when to use this tool versus alternatives. Sibling tools like sensor_audio, sensor_fuse, and wm_encode exist, but the description gives no indication of the use cases, prerequisites, or differentiation needed for selection.

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