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

Without annotations, the description carries the full burden. It discloses the core effects of each action, including creating at a beat time, deleting, jumping the playhead, and listing locators, but it omits important behavioral details such as whether deletion is destructive, whether indexes shift after deletion, and what happens with invalid indexes.

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 a single front-loaded sentence followed by a compact action list. Every phrase contributes scope or action information, with no redundant or filler text.

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 actions and resource sufficiently for basic invocation, and the schema fully documents parameters. However, with no annotations and no output schema, it does not describe return values for 'list' or important side-effect details for mutation actions, leaving 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?

The schema has 100% description coverage and fully documents the action enum and parameters. The description adds only high-level action context, such as 'create locator at beat time,' which is already available in the schema, so baseline 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 states a specific resource, 'arrangement locator cue points in Ableton Live 12,' and enumerates the exact operations: create, delete, jump, and list. This distinguishes it from sibling transport, clip, and scene tools by scope and resource.

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 action list makes the tool's appropriate uses clear, and the phrase 'arrangement locator cue points' gives strong context. However, it does not explicitly name alternatives or state when not to use this tool versus transport or clip operations.

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