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

No annotations are provided, and the description only covers parameter meanings. It does not disclose behavioral traits such as what happens if already connected, error conditions, or whether the operation is safe/destructive.

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 concise, starting with a clear one-line purpose followed by a structured list of arguments. No unnecessary 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 lacks crucial information such as return value (e.g., connection handle) and side effects (e.g., global state changes). Given the tool complexity and absence of output schema, this is insufficient.

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?

With 0% schema description coverage, the description fully explains each parameter: interface types and examples, channel naming conventions, and common baudrates. This adds substantial meaning beyond the default values in 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 explicitly states it opens a CAN interface connection, specifying supported interface types (pcan, virtual). This clearly distinguishes it from siblings like disconnect and list_interfaces.

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 implies this is a setup step before using other tools like capture or analyze_message, but provides no explicit guidance on when to use or avoid it, or alternatives.

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