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

Adds useful behavior beyond the annotations: the target bin is created if missing, supported media types are enumerated, and numberedStills has defined sequence-import behavior. It does not cover collision/duplicate handling or failure modes, but with annotations already declaring safety and mutation hints, this is solid.

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 compact sentences with the main action and scope front-loaded. Every clause contributes useful information, including supported formats and the numberedStills exception.

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 three-parameter import tool with no output schema, the description gives enough to call it correctly: what can be imported, where it goes, bin creation behavior, and sequence handling. It could say more about returned results or error behavior, but the core invocation context is present.

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. It meaningfully explains bin creation, the media types appropriate for paths, and the numberedStills option, though it does not specify path formatting or bin naming details.

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 and resource: importing media files into a Premiere Pro bin. It also lists supported file types and names the numberedStills behavior, making the tool clearly distinct from generic imports, though it does not explicitly contrast with sibling import tools.

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?

Implies when to use the tool through 'Premiere Pro: import media files into a bin,' but gives no explicit when-to-use, when-not-to-use, or sibling alternative guidance such as media_import or ae_importFile.

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