Add audio / music

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

No annotations are provided, so the description carries full burden. It discloses that the tool 'imports if needed' and allows trimming via inSeconds/outSeconds. However, it does not mention the behavior of the 'mode' parameter (overwrite/insert), whether tracks are created if missing, or any error conditions.

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?

Two sentences concisely convey the main purpose and optional trimming. Front-loaded with the primary action. Could include more behavioral details without being verbose, but current structure is efficient and not wasteful.

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 has 6 parameters, no output schema, and no annotations, the description is adequate but not exhaustive. It covers the core functionality and trimming, but lacks explanations for mode, track handling, and import implicit steps. For a tool of this complexity, more details would enhance completeness.

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 50% (3 of 6 parameters described). The description adds context by naming media types and mentioning trimming parameters (inSeconds/outSeconds), but does not explain mode or atSeconds beyond what the schema provides (e.g., start time default 0). Baseline of 3 is appropriate with moderate added value.

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 action ('Place an audio file on an audio track'), specifies the resource ('audio file: music, SFX, voiceover'), and mentions optional trimming. It distinguishes itself from sibling tools like premiere_place_clip and premiere_add_overlay by focusing specifically on audio placement.

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 implies usage for adding audio to a track at a given time, but lacks explicit guidance on when to use this tool vs. alternatives (e.g., premiere_place_clip for general clips, premiere_add_effect for effects). No prerequisites or when-not-to-use conditions are mentioned.

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