play_enhanced_quake_sound

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

Annotations already indicate this is not read-only, not destructive, not idempotent, and open-world. The description adds valuable context beyond annotations: it specifies that playback occurs on the local system, updates session statistics, and supports 25 achievements across 5 categories. However, it doesn't mention potential side effects like system audio requirements or what 'updates session statistics' entails.

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 efficiently structured with two sentences that pack substantial information: the first states the core functionality with key features, the second provides important contextual details about achievement categories and statistics. Every element serves a purpose with no wasted words.

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 tool's moderate complexity (3 parameters, no output schema, rich annotations), the description provides good coverage of what the tool does and its key features. It could be more complete by explaining what 'updates session statistics' means in practical terms or mentioning any prerequisites for audio playback, but it adequately covers the tool's purpose and scope.

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?

With 100% schema description coverage, the input schema already thoroughly documents all three parameters with detailed descriptions and examples. The description adds marginal value by mentioning 'dual voice pack support' which relates to the voiceGender parameter, but doesn't provide additional semantic context beyond what's 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 clearly states the tool's purpose with specific verbs ('Plays', 'Triggers', 'Updates') and resources ('high-quality enhanced Quake 3 Arena achievement sound', 'session statistics'). It distinguishes itself from siblings by focusing on audio playback with achievement-specific functionality, unlike get_* tools that retrieve information or set_* tools that configure settings.

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 provides clear context for when to use this tool: for playing achievement sounds with dual voice pack support and updating statistics. However, it doesn't explicitly state when NOT to use it or mention alternatives like random_enhanced_achievement for random playback or set_enhanced_volume for volume control without playback.

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