als_details

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

Annotations already declare readOnlyHint=true and openWorldHint=false. The description adds further context: 'offline' and 'reviewing a mix without Live', reinforcing the non-destructive, offline nature. No contradictions, and it provides behavioral context beyond annotations.

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 sentence that is front-loaded with the action ('Read mixing and arrangement detail') and efficiently conveys purpose, scope, and relationship to siblings. No extra words, every part earns its place.

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 presence of an output schema (not shown), the description need not detail return values. It sufficiently lists the data read (locators, track volume/pan/automation lanes). While it lacks mention of error conditions or limitations, the tool is simple and the description is adequate for its complexity.

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?

There is only one parameter (path) with no description in the schema (0% coverage). The tool description does not add details about the parameter, such as expected format or constraints. However, the parameter is intuitively the file path to the .als file, so the omission is partially mitigated.

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 reads mixing and arrangement details from a saved .als file, listing specific data (locators, track volume/pan/automation lanes). It distinguishes itself from sibling als_summary as a complement, making the 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?

The description indicates the tool is for offline review of a mix without Live, and it complements als_summary. While it doesn't explicitly state when not to use it or list alternatives beyond als_summary, the context is clear enough for an agent to infer usage scenarios.

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