audiobookCreate audiobooks from web content or text files. An agent skill from benchflow-ai/skillsbench.
Audiobook is an agent skill from benchflow-ai/skillsbench. Create audiobooks from web content or text files. Handles content fetching, text processing, and TTS conversion with automatic fallback between ElevenLabs, OpenAI TTS, and gTTS.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Text to speech and voice. It works with ElevenLabs and OpenAI. The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 9a1f4dd. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
api.elevenlabs.ioapi.openai.comFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
OPENAI_API_KEYELEVENLABS_API_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Audiobook loads about 2.4k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 230 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Audiobook fits situations like: tasks that involve Text to speech and voice.
Run `npx skills add benchflow-ai/skillsbench --skill audiobook -a claude-code`. Or copy the skill folder (tasks-extra/pg-essay-to-audiobook/environment/skills/audiobook in benchflow-ai/skillsbench) into .claude/skills/audiobook in your project. Claude Code loads it when a task matches its description.
Run `npx skills add benchflow-ai/skillsbench --skill audiobook -a codex`. Or copy the skill folder (tasks-extra/pg-essay-to-audiobook/environment/skills/audiobook in benchflow-ai/skillsbench) into .agents/skills/audiobook in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add benchflow-ai/skillsbench --skill audiobook -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/audiobook, .gemini/skills/audiobook, .github/skills/audiobook and .opencode/skills/audiobook in your project.
Going by SKILL.md and its folder, Audiobook needs credentials named OPENAI_API_KEY and ELEVENLABS_API_KEY. Our summary lists: Python 3; A credential in ELEVENLABS_API_KEY; A credential in OPENAI_API_KEY.
SKILL.md names 2 domains. In commands or code: api.elevenlabs.io and api.openai.com; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Audiobook is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.4k tokens (SKILL.md is roughly 9.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Audiobook: Video Translator (shang-zhu/violin, 1.1k stars), 9Router Text to Speech (decolua/9router, 30k stars), Super Video Maker (Bomx/super-video-maker-skill, 308 stars) and Motion Video (bestagentkits/motion-video-skill, 113 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
