get_history_state

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is known. The description adds the notion that this reflects 'current' availability, which is contextual but minor. No contradictions, but also no extra behavioral detail such as return format or side effects.

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 no extraneous words. It states exactly what the tool reads, making it appropriately sized for such a simple operation.

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 zero-parameter read-only tool with annotations covering safety, the description is complete. It clearly identifies the resource being read and is sufficient for an agent to invoke the tool correctly. No output schema exists, but the return value ('availability') is adequately implied by the description.

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 parametersainer, so the baseline is 4. The description need not compensate for undocumented parameters, and there is nothing to clarify beyond the schema.

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 states a specific verb ('Read') and a precise resource ('current Ableton undo and redo availability'). It clearly distinguishes this read-only state query from siblings like 'undo' and 'redo', which perform actions, and from 'get_live_state', which covers broader state.

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 implies use as a read-only check of undo/redo availability, but it does not explicitly say when to prefer this over siblings like 'undo', 'redo', or 'get_live_state'. No exclusions or alternate routing are provided, leaving the agent to infer the context.

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