Create set navigator

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

Annotations indicate non-read-only and open-world behavior; the description adds that the navigator 'drives manage_cue recall' on the target, revealing a side effect, and mentions optional beat quantization. However, it doesn't disclose potential failure modes, prerequisites beyond the stated workflow, or what exactly changes on the target, leaving some behavioral gaps.

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?

The description is concise at three sentences, front-loaded with the main purpose, then features, then usage context. Every sentence contributes unique value with no redundancy or 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?

The description covers the tool's purpose, interaction model, integration with manage_cue, and when to use it. It lacks an explicit return value description, but the schema's parameter descriptions and the absence of an output schema make this a minor omission. Overall, it's sufficiently complete for a creation tool.

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 input schema has 100% parameter coverage with descriptive text for each parameter. The description adds minimal parameter-level detail, only referencing 'quantize GO' which aligns with go_on_beat. Since the schema already handles parameter semantics, the baseline of 3 is appropriate.

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 it builds a 'hands-light stage navigator' with specific interactions (Next/Prev/Go/Index), and distinguishes it from other create tools by referencing the QLab model and its reliance on manage_cue. The verb 'Build' and resource are 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?

It gives clear usage context: 'Use after building a control panel with manage_cue cues stored' and contrasts with 'instead of recalling by name.' It doesn't explicitly name alternative tools, but provides a clear workflow and an alternative approach, meeting the threshold for good guidance.

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