ecamm_sound

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds useful behavior (volume range 0-100, loop/restart modes, accepting name or id), but says nothing about what happens on stop/pause when nothing is playing, whether play replaces or stacks sounds, or what is returned.

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 that leads with the resource and then enumerates operations with parenthetical qualifiers. Dense but every clause carries information; no filler.

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 four-parameter, no-output-schema action tool with annotations present, this covers the operation set, the required parameter's formats, and the volume range. Remaining gaps are edge-case behavior (stopping with nothing playing, restart-vs-loop semantics) rather than anything blocking a correct call.

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 only 50% schema coverage, the description compensates well: it clarifies that 'sound' accepts a name or an id (schema only says 'Required for play'), states the volume bounds, and maps loop/restart to playback behavior. The only soft spot is that the schema's 'stop' value for mode overlaps confusingly with the stop action, which the description does not reconcile.

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?

Names the resource (sound effects) and enumerates the concrete operations: play, stop, pause, volume. The phrase 'set volume of the playing sound' distinguishes it from the sibling ecamm_set_volume without naming it outright, so the boundary is inferable rather than explicit.

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?

Usage is implied by the self-describing action names, but there is no explicit when-to-use guidance, no statement of prerequisites (e.g., must a sound be playing to pause/stop), and no pointer to ecamm_set_volume for non-sound-effect volume changes.

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