set_sound_effect_mode

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

With no annotations, the description carries full burden. It discloses that the mode is persisted via '_saveSettings', covering a key behavioral trait. It does not mention immediate effect on sound output or side effects, but for a simple mode switch, this is adequate.

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 two sentences, no fluff. It front-loads the action and explains each mode efficiently. Every sentence 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 one parameter, no output schema, and no annotations, the description is largely complete. It covers mode values and persistence. It could optionally mention immediate effect, but not essential for a simple switch.

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 does so by explaining each enum value of the 'mode' parameter in detail, adding meaning beyond the raw enum list in the schema.

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 uses specific verb 'Switch' and resource 'EffectsEngine mode', lists all five enum values with clear explanations, and distinguishes from sibling tools like set_sound_hook and set_active_sound_pack that handle different aspects of sound effects.

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 explains what the tool does but does not provide explicit guidance on when to use it versus alternatives (e.g., set_sound_hook for per-hook sounds, set_active_sound_pack for pack selection). The purpose is clear, but no 'when not to use' or alternative references are given.

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