get_acquisition

Read-only

Read the current acquisition mode (continuous or single sweep), sweep time in seconds, and auto flag for a selected spectrum analyzer.

Instructions

Get the acquisition mode: continuous (true) or single sweep (false), plus the sweep time (s) and its auto flag. Note: over the raw transport the instrument ignores all commands while a single sweep is running; over VXI-11 it queues them.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

TDQS

A4.2/5.0
Behavior5/5

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

Beyond the readOnlyHint annotation, the description discloses a genuinely important operational trait: over the raw transport the instrument ignores all commands while a single sweep is running, whereas over VXI-11 commands are queued. It also decodes the boolean return ('continuous (true) or single sweep (false)'), which annotations cannot convey.

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

Conciseness5/5

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

Two tight sentences: the return contract comes first, then the transport caveat. Every clause carries information an agent needs, with no restatement of the name or filler.

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

Completeness4/5

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

With no output schema, the description carries the burden of describing return values, and it does so for all three fields including units and boolean polarity. Only the precise field names/shape of the returned object remain unspecified, a minor gap for a simple getter protected by readOnlyHint.

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

Parameters3/5

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

There is a single optional parameter and schema description coverage is 100%, so the schema already explains that 'instrument' takes a name from list_instruments and defaults sensibly. The description adds nothing further about parameter behavior, which is the baseline-3 case.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ('Get the acquisition mode') and enumerates exactly what is returned: the continuous/single-sweep boolean, the sweep time in seconds, and its auto flag. It is trivially distinguishable from the sibling set_acquisition by both name and stated read intent.

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 usage context is only implied: an agent can infer this is the read side of acquisition configuration versus set_acquisition, but the description never states when to call it (e.g., before starting a sweep, to verify configuration) or any prerequisite checks. The transport caveat is a behavioral note rather than usage guidance.

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