TTS 작업 접수

tts_jobs_create

한국어 TTS를 접수합니다. 기본 정규화 스킬이 발음을 다듬으며 추가 요금이 합산됩니다. normalize_text=false로 끌 수 있습니다. 완료 후 MP3와 원문 ASS를 공통 API로 받습니다. 서버·공급자 최종 실패 시 정규화까지 전액 환불하고, 연결 종료는 정상 과금합니다. [실제 토큰 원가×환율×1.4(작업당 기본요금 5P, 2026-11-06부터 · 소수점 올림) + 기본 on 정규화 스킬 요금]

TDQS

A3.6/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=false, so mutation is known; the description goes further with genuinely useful behavior: default-on normalization that adds cost, full refund on server/provider failure, connection termination billed normally, and the output artifacts (MP3 + original ASS). This is well beyond what the annotations convey.

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

Conciseness4/5

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

Purpose and cost behavior are front-loaded in the first sentences. The bracketed pricing formula is dense but arguably earns its place since it is billing-relevant and not captured elsewhere. Slightly heavy overall but no dead sentences.

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?

For a 14-parameter, zero-required, async creation tool with no output schema, the description usefully discloses the return artifacts and refund/billing rules. It stops short of explaining how the resulting job is tracked (e.g., via tts_jobs_status/tts_jobs_result) or whether a job id is returned, which would complete the picture.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3, but the description adds real semantic value beyond the schema: normalize_text=false skips both execution and billing, and voice_id defaults to 'Kore' with a pointer to tts_gemini_voices for listing. The pricing formula also explains cost-driving parameters.

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

Purpose4/5

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

States a specific verb+resource (submit Korean TTS job) and covers scope details like normalization and delivery format. However it never distinguishes this tool from the sibling creation tools tts_gemini_create and tts_openai_create, leaving the agent to infer which one to call for a given provider.

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

Usage Guidelines2/5

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

The description explains that normalize_text can be turned off and what happens on failure, but gives no explicit when-to-use guidance relative to the other TTS creation tools. With three near-identical create siblings, the absence of routing guidance is a real gap.

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