sensor_visual

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only states 'Visual Encoding' but does not reveal whether the tool reads sensor data, generates simulated data, mutates state, or requires permissions. The input parameter 'simulate' hints at simulation, but no side effects or constraints are documented.

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 concise (one sentence) but at the expense of clarity and completeness. It is not structured to front-load key information; instead, it reads as a cryptic label. Over-conciseness here is detrimental.

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 (nested input object, video frames parameter, no output schema), the description is severely incomplete. It lacks information about return values, prerequisites, capabilities, and constraints. The description adds negligible value beyond the tool name.

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% with each parameter having a description in the schema. The tool description adds context about V-JEPA 2 and image/video processing but does not provide significant additional meaning beyond the schema. Baseline 3 is appropriate as the description complements but does not substantially enhance the schema.

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)' vaguely indicates the tool performs visual encoding for images or videos. However, it lacks a specific verb (e.g., 'encode', 'process', 'generate') and does not clearly differentiate from sibling tools like np_camera_capture or sensor_process. The purpose is somewhat clear but not sufficiently specific.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, typical use cases, or when not to use it. Given the presence of many sensor tools, this omission is significant.

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