snapshot_state

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

No annotations provided, so description carries full burden. It discloses filename validation constraints and that it saves full mixer state. However, does not mention overwrite behavior, permissions, or destructive potential.

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?

Single sentence with no wasted words. Front-loads the action and includes essential detail about state scope and naming rule.

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 simple tool with one parameter and no output schema, description fully covers purpose, usage hint, and parameter constraint. No gaps given the tool's 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?

Input schema has 0% coverage and only parameter 'name' with default. Description adds meaningful constraint: filename must be letters/digits/_/- only, providing key semantic that schema lacks.

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?

States verb 'Save', resource 'full mixer state', and filename constraint 'letters/digits/_/- only'. Clearly distinguishes from siblings like 'load_preset' and 'diff_vs_snapshot'.

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?

Provides specific usage context: 'Take one when the stream sounds RIGHT.' While implicit, it gives clear when-to-use direction. No explicit when-not or alternatives, but sibling list aids differentiation.

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