live12_lom_set

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

With no annotations, the description must carry the full behavioral burden. It usefully states that only writable properties are targeted, but it does not disclose side effects, error behavior for invalid paths or non-writable properties, whether changes are undoable, or any permission or rate-limit context.

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 with no redundant or wasted text. It efficiently communicates the core 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 generic mutation tool with no annotations and no output schema, the description is too sparse. It does not explain validation behavior, failure modes, or the consequences of setting an invalid or read-only property, leaving important operational context missing.

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?

Schema description coverage is 100%, so all three parameters are already documented in the schema. The description adds no parameter-specific meaning beyond the schema's examples and types, so 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 states a specific verb and resource: 'sets the value of any writable property on an object in the Ableton Live Object Model (LOM).' This clearly distinguishes setting from sibling operations like live12_lom_get and live12_lom_call, though it does not explicitly name those alternatives.

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 implies usage by saying it sets writable LOM properties, but gives no explicit when-to-use guidance, no exclusions, and no comparison to live12_lom_get, live12_lom_call, or live12_lom_inspect.

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