export_dbc

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

No annotations are provided, so the description carries full burden. It fails to disclose whether the operation overwrites or appends to the file path, any permissions needed, error states, or if it is synchronous. The description implies a read operation but it writes a file, making transparency crucial.

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: two sentences plus a structured Args section. All information is front-loaded with no redundant words. Every sentence adds value.

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 no output schema and no annotations, the description covers the basic purpose and parameter, but lacks details on error handling, side effects (e.g., file overwrite), or scope of exported signals. For a file-writing tool, this is moderately incomplete.

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?

The description clarifies that 'file_path' must be an absolute path for a '.dbc' file, adding meaning beyond the schema's generic 'File Path' string. With 0% schema coverage, this compensation is valuable, though it is limited to just one parameter.

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 verb 'export' and resource 'all current signal definitions' with the output format 'DBC file'. It also mentions compatibility with common CAN tools, which adds context. This distinguishes it from siblings like import_dbc and list_signals.

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 like import_dbc. It does not specify prerequisites, when not to use, or compare to other export or file-handling tools. Users are left to infer usage context.

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