remove_silence

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

With no annotations, the description carries the full burden and does well: it discloses that silence is destructively removed from the output, that sync is preserved, and that output defaults to '{name}_no_silence.{ext}' (implying a new file rather than in-place edit). It omits overwrite behavior when output_path already exists and any failure/error characteristics.

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 purpose sentence is front-loaded and the Args block is well organized and easy to scan; there is minor waste in restating defaults already present in the schema and in a Returns section that partly duplicates the output schema.

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 five-parameter media tool with one required input and an output schema already documenting return values, the description supplies nearly everything needed - parameter meaning, output naming, sync guarantee. It falls short only on overwrite/error behavior and environment prerequisites.

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, and it does: every one of the five parameters is explained with meaning plus a concrete example or default (dB example -30.0, 0.5s minimum silence, 0.1s padding rationale of avoiding clipped speech).

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 opens with a specific verb and resource ('Cut silent gaps from a video or audio file') plus the key quality guarantee ('keeping video and audio perfectly in sync'), which immediately separates it from siblings like smart_crop_vertical and apply_lut_grade.

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 purpose - an agent knows to call this when removing dead air - but there is no explicit guidance on when not to use it, no prerequisites (e.g. ffmpeg availability), and no comparison to the other media-processing siblings.

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