get_scope_state

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

With no annotations provided, the description carries the full burden. It implies a read-only operation ('snapshot') and explicitly discloses the concurrency restriction, which is a behavioral trait. It does not detail return format or error behavior, but for a simple getter this is adequate.

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?

Two sentences with no waste: the first states purpose and scope, the second gives usage context and a constraint. Every sentence earns its place, and the key information is front-loaded.

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?

Given the tool has no parameters and no output schema, the description covers the essential purpose and usage. It lists the main fields returned (channels, timebase, trigger) but does not specify exact format or units. For a simple snapshot tool, this is reasonably complete, though a bit more detail on return structure would push it higher.

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?

The tool has zero parameters, so the baseline for this dimension is 4 per the rubric. The description appropriately avoids explaining parameters since there are none.

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 returns a snapshot of the scope's current configuration, listing specific elements (active channels, timebase, trigger). This distinguishes it from sibling setter tools (set_channel, set_timebase, set_trigger) and getters like get_cursor_values, making its purpose unambiguous.

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?

It provides explicit when-to-use guidance ('at the start of a session to understand the current setup') and a clear when-not constraint ('Do not call concurrently with any other rigol tool'). It does not name alternatives, but no sibling serves the same purpose, so this is sufficient.

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