Generate Voiceover

generation_voiceover_create
DestructiveIdempotent

Queue a text-to-speech voiceover into the BlitzReels media library. Spends AI credits and returns a job to poll with generation_jobs_get.

TDQS

A4.2/5.0
Behavior4/5

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

Adds valuable context beyond annotations: it consumes AI credits (cost awareness) and is asynchronous (returns a pollable job). These aren't captured by the hints. Annotation destructiveHint=true is odd but not contradicted — queueing a job writes to the library.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences with zero waste; the action and the key behavioral facts (credit spend, async job) are front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values needn't be explained, and annotations cover safety flags. The description supplies the credit and async-polling essentials. Minor gap: no mention of idempotency for retries, though the schema covers the key.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so all six parameters (text, speed, voiceId, voiceStyle, workspaceId, idempotencyKey) are already documented. The description adds nothing parameter-specific, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Queue) and resource (text-to-speech voiceover) with destination (BlitzReels media library). Clearly distinguishable from sibling generators like generation_image_create or generation_music_create.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides a clear workflow signal: it returns a job to poll with generation_jobs_get. However, it doesn't explicitly contrast voiceover generation against sibling generation_* variants or state when-not to use it.

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