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

Annotations already declare destructiveHint=false, indicating no destructive behavior. The description adds action details but doesn't clarify recall's overwrite behavior or side effects. Some behavioral traits remain implicit.

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 with minimal but complete information, front-loading the core concept. Every word serves a purpose without redundancy.

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?

Although an output schema exists (reducing need to describe return values), the description fails to explain critical parameters like track_index and device_index. The tool has moderate complexity with 4 parameters, and the description covers only half adequately.

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 0%, so the description must compensate. It explains 'action' and 'index' but omits 'track_index' and 'device_index', which are required. This leaves significant gaps for an agent to correctly invoke the tool.

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 manages 'rack macro snapshots' with three specific actions: store, recall, randomize. This is a specific verb-resource pair that distinguishes it from sibling tools like 'get_rack_chains' or 'set_device_parameter'.

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 explicitly lists when to use each action (store to save, recall to restore, randomize for exploration). While it doesn't mention exclusions or alternatives, the context is clear for a specialized tool.

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