Behavior2/5

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

The term 'preview' implies a read-only, non-destructive operation, but no explicit confirmation or additional behavioral details are given. With no annotations provided, the description fails to clarify whether permissions are checked, what format the preview output takes, or if any state is affected.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single 4-word sentence, which is concise but severely under-specified. It lacks any structure that would help an agent quickly parse key information, such as bullet points or distinct sections for purpose, usage, or parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is highly incomplete given the tool's complexity (3 parameters, no output schema, no annotations). It does not define 'unsealing', explain the preview mechanism, or provide any context about return values or side effects, leaving the agent with insufficient information to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description does not explain any of the three parameters (oid, sensor_id, token_ttl_seconds). Given 0% schema description coverage, the description should compensate but adds no meaning beyond the parameter names. The agent has no insight into what these values represent or how they affect the operation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Preview unsealing') and the resource ('one sensor'), which aligns with the tool name. However, it does not differentiate this tool from its sibling 'lc_preview_seal_sensor' or other preview tools, missing an opportunity to clarify the specific scope.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like 'lc_preview_seal_sensor' or 'lc_get_sensor_seal_status'. The description does not indicate prerequisites or conditions for use, leaving the agent without contextual decision-making support.

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