Behavior2/5

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

With no annotations available, the description must carry the full behavioral burden. It mentions 'workflow' and 'CSV analysis' but doesn't disclose whether the tool connects to an instrument, modifies settings, writes files, or what side effects occur, leaving the agent with substantial uncertainty.

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

Conciseness4/5

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

It is a single short sentence, making it very concise and front-loaded. The word 'candidate' is somewhat extraneous but does not significantly impair readability.

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

Completeness2/5

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

For a tool that likely orchestrates multiple steps (capture, analysis) and returns a structured output schema, this description is far too sparse. It doesn't explain the workflow steps, expected outputs, or relationship to sibling tools.

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 schema has 0% description coverage and the description does not mention channel, max_points, or logic_level. Since the description must compensate but doesn't, the agent lacks semantic understanding of these parameters.

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 identifies the tool as a one-shot workflow for 2 Mbps UART capture and CSV analysis, which conveys its core function and distinguishes it from the automatic variant (capture_uart_auto_tcp) and the file-analyzer (analyze_uart_csv_file). However, it is phrased as a noun phrase rather than a direct action, with 'candidate' adding ambiguity.

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

Usage Guidelines3/5

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

The phrase 'one-shot' implies a single capture scenario, but the description provides no explicit guidance on when to choose this tool over capture_uart_auto_tcp or analyze_uart_csv_file, nor does it mention prerequisites or exclusions.

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