record

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

With no annotations provided, the description carries full burden, but it only states the basic action. It does not disclose file overwrite behavior, whether recording is blocking or async, or what happens if parameters are invalid (e.g., seconds=0).

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?

Single sentence that is front-loaded with the verb and key resource ('Record the live stream'), no extraneous words, and clear structure.

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 tool's complexity is moderate (3 parameters, no output schema). The description covers the main action but omits important context like error handling, file overwrite behavior, and return value. It is minimally adequate but not comprehensive.

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?

Schema description coverage is 0%, so description must add value. It explains 'fmt' with formats (npz/csv/edf) and mentions 'seconds' and 'file'; however, it does not detail the 'path' parameter or constraints on 'fmt' values.

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 tool records a live stream for a specified duration to a file with specific formats (npz/csv/edf). It is distinct from siblings like 'connect' or 'calibrate', though the stream type (e.g., EEG) is implied rather than explicit.

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?

No guidance on when to use this tool versus alternatives. Missing prerequisites (e.g., must be connected to a device) and conditions like when recording might fail or should not be used.

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