sdr_connect

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

No annotations are supplied, so the description carries the full behavioral burden, yet it says nothing about whether the connection is exclusive or persistent, what happens if the device is busy or the wrong type, or whether it must be torn down with sdr_disconnect. The enum values and device types are the only behavioral facts conveyed.

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?

A single front-loaded sentence with the action and target first. The tail listing spectrum analysis, scanning, recording and transmit is slightly wasteful since those belong to sibling tools, but it remains compact with no filler.

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?

For a two-optional-parameter connect tool with no output schema, the description covers the what but not the return value (handle/session identifier), success/failure behavior, or lifecycle tie-in to sdr_disconnect. Adequate as a minimum-viable entry point but with clear gaps.

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 coverage is only 50%: device_index is documented in-schema, while device_type is an undescribed enum with a default. The description partially compensates by naming the two supported hardware families (RTL-SDR, HackRF), which map onto the enum values, but it adds no detail on default selection or multi-device behavior.

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 names a specific verb ('Connect') and resource ('SDR hardware (RTL-SDR or HackRF)') and scopes it to Python-side control, which is enough to separate it from sdr_disconnect and sdr_list_devices. It doesn't explicitly name a sibling as the alternative, which keeps it from a 5, and the trailing capability list describes what other tools do rather than this one.

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 never states when to call this versus alternatives (sdr_list_devices, sdr_disconnect) or that it should precede the set_frequency/set_sample_rate tools. Prerequisites such as installing drivers or enumerating devices first are left entirely to inference.

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