pause_other_audio

Pause music or media from other apps to prevent audio bleed into recordings. Use before starting a recording or when asked to stop the music.

Instructions

Pause any music or media playing in other apps (Spotify, Apple Music, browsers, VLC) so it doesn't bleed into a recording. Use this BEFORE start_recording when the user is listening to music, or whenever the user says "pause my music", "stop the music", or "mute Spotify". Returns per-app attempts so the agent can describe what was paused. Best-effort cross-platform: macOS uses AppleScript to Music + Spotify (guarded by "is running"); Windows sends VK_MEDIA_PLAY_PAUSE (toggle key — same key used for resume); Linux uses playerctl pause (covers any MPRIS-compatible player). On Linux the response includes an install hint when playerctl is missing.

A4.6/5.0
Behavior5/5

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

With no annotations provided, the description fully carries the burden of transparency. It discloses that the tool is best-effort cross-platform, details platform-specific methods (macOS AppleScript, Windows toggle key, Linux playerctl), notes the toggle key on Windows can also resume, and mentions an install hint when playerctl is missing on Linux. This goes beyond basic functionality to cover important behavioral traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is somewhat lengthy but well-structured, front-loading the main purpose and usage, then detailing platform specifics and return value. Every sentence contributes value, though the platform details could be condensed slightly. Overall, it is efficiently written for an agent's consumption.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given zero parameters, no output schema, and no annotations, the description provides comprehensive context: when to use, how it works per platform, what it returns (per-app attempts), and additional notes (install hint on Linux). An agent using this tool would have sufficient information to invoke it correctly and understand its behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has zero parameters, and schema description coverage is 100%. According to guidelines, a tool with no parameters has a baseline score of 4. The description does not add parameter info because none exist, so this baseline is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool pauses music/media in other apps, listing specific examples like Spotify, Apple Music, browsers, and VLC. It specifies the verb 'pause' and the resource 'other apps audio', making the purpose unmistakable. The distinction from the sibling 'resume_other_audio' is implied but not explicit, yet the purpose is very clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit usage context: 'Use this BEFORE start_recording when the user is listening to music, or whenever the user says "pause my music", "stop the music", or "mute Spotify".' It does not explicitly state when not to use or mention alternatives, but the context is clear and sufficient for an agent to decide.

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