+]v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full behavioral burden. It usefully discloses the non-obvious trait that no OS audio is produced, but omits whether the operation is idempotent, what session state it affects, or how project_path influences scope.
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?
A single front-loaded sentence with no filler; the key distinction (no OS audio) is included without padding.
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?
An output schema exists, so return values need not be explained. Still, the description leaves the optional project_path parameter and the tool's interaction with session state unaddressed for a two-parameter tool.
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. 'Start or pause' loosely implies the boolean semantics of 'playing', but project_path is entirely undocumented and its optional role is left unexplained.
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 a specific verb (start/pause) and resource (DAW browser transport), which clearly conveys toggling playback state. It does not explicitly contrast itself with close siblings like stop_session_tool or play_audio_tool, so it falls short of a 5.
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 parenthetical '(no OS audio)' hints that this is for transport state rather than audible playback, implying play_audio_tool is the audible alternative. However, there is no explicit when-to-use statement, prerequisite, or named alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
