Venice Video Transcriptions

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

With no annotations provided the description carries the full burden. It mentions the auth paths (x402 wallet vs API key), which is useful behavioral context. However, it doesn't disclose limits like max video length, supported languages, whether the entire video is transcribed or a segment, or any cost/rate-limit implications. The 'transcript' nature implies a read-only outcome but this isn't explicitly confirmed.

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 description is a compact 3-sentence block that conveys the core action, operator preference, and auth options without waste. Each sentence earns its place. It could arguably merge some clauses, but nothing is verbose or redundant.

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 2-param tool with no nested objects and no output schema, the description is reasonably complete: it names the source (YouTube), the outcome (transcript), and auth paths. Gaps remain: no explanation of response_format behavior, no stated limitations (video length, language), and no detail on operator preferences. This is adequate but not thorough for a transcription service where input size and format expectations matter.

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 coverage is 50%, and the description describes the url parameter ('YouTube URL → text transcript') and references 'youtube-default' operator preference, adding modest context. However, the response_format param (enum: json/text) is in the schema but not described in the prose at all, and the description doesn't explain default responses or format differences. The description adds minimal value beyond what the schema already conveys.

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 verb ('Transcribe') and resource ('YouTube video URL'), and specifies the output ('text transcript'). This distinguishes it from siblings like venice_asr (which likely handles different input types) and venice_video_generate (video creation, not transcription). However, it doesn't explicitly contrast with venice_asr or venice_text_parser, leaving slight ambiguity about which transcription tool to choose.

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 mentions 'Operator preferences — default: youtube-default' and 'Supports x402 wallet auth (no Venice account needed) and API key', which gives some context on auth options. However, it provides no when-to-use guidance, no exclusions versus venice_asr (which may also transcribe audio/video), and no indication of when to prefer this over alternatives. 'Operator preferences' is mentioned but not explained in a way an agent can act on.

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