analyze_uart_csv_file

Analyzes UART waveforms from CSV files with time and voltage columns, decoding serial data based on configurable baud rate.

Instructions

Analyze a two-column UART waveform CSV: time_s, voltage_v.

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Analyze', which is vague and does not disclose what happens during analysis, what the output contains, or how baudrate affects behavior. There is no mention of decoding UART data, error handling, or performance implications.

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?

The description is a single, concise sentence that earns its place by defining the CSV format. It is front-loaded and contains no filler, though it may be too terse for the tool's complexity.

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?

Given the tool's role in UART analysis and the presence of an output schema, the description is still insufficient. It does not explain the analysis process, the role of baudrate, or when to invoke this tool. The single sentence provides minimal context and leaves the agent to infer critical details.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate. It adds context for csv_path by defining the column structure (time_s, voltage_v), but entirely ignores baudrate, which is a meaningful parameter for UART analysis. The description does not explain why baudrate is needed or how it interacts with the waveform data.

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 tool analyzes a UART waveform CSV and specifies the two-column format (time_s, voltage_v). This distinguishes it from sibling tools like analyze_rs485_pair_csv_file. However, it doesn't specify what kind of analysis is performed (e.g., decoding, timing measurement), leaving some ambiguity.

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 capture_uart_auto_tcp or analyze_rs485_pair_csv_file. The description implies offline analysis of a CSV, but does not mention prerequisites, differentiators, or exclusions.

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