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

The annotations establish the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true), so the bar is lower. The description adds real behavioral value by disclosing that the call 'consumes the account's clip-minute allowance,' a billing side effect not captured by annotations, but it omits job/async semantics and failure behavior for a 15-parameter queuing operation.

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 tight sentences with zero filler, and the core action plus its batch limit is front-loaded. Nothing is wasted, though there is little beyond the essentials.

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 tool with 15 parameters, nested option objects, and no output schema, the description is far too thin. It should at least hint at the async job lifecycle (polling via get_clip_job_status) and the primary option groups, none of which appear.

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 only 7%, so the description must compensate and largely does not. It conveys the single-vs-batch behavior and the 10-item cap (matching url/urls), but says nothing about the remaining 13 parameters, including the nested options object with layout, mode, format, quality, brand_kit, and clip-count/duration controls.

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 ('Queue one video URL, or a batch of up to 10 video URLs, for AI clipping') with clear scope and the batch limit. However, it does not differentiate itself from siblings like get_clip_job_status, estimate_clone, or list_clip_jobs, which an agent would need to disambiguate an async job tool.

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?

There is no explicit when-to-use or when-not-to-use guidance and no named alternative (e.g., checking allowance via get_clip_minutes first, or polling with get_clip_job_status). Usage is only implied by the verb 'Queue ... for AI clipping'.

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