bytedance/agentkit-samples is a collection of examples and tutorials for Volcengine AgentKit, an AI-agent development platform for building, deploying, and operating agent applications. Developers use the samples to learn agent creation, multi-agent collaboration, memory, retrieval, MCP integrations, media generation, customer service, and other workflows. The catalogue skills provide agent workflows based on these examples.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00062 | $0.01954 |
| Opus 5 | $0.00031 | $0.00977 |
| Sonnet 5 | $0.00012 | $0.00391 |
| Haiku 4.5 | $0.00006 | $0.00195 |
Grade A, and why
byted-music-generate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Music Generate Skill
Generate music using the Volcengine Music Generation API. Supports vocal songs, instrumental BGM, and AI lyrics generation.
Trigger Conditions
- User wants to generate a song (with lyrics or a text prompt)
- User needs background music, instrumental tracks, or soundtracks
- User wants AI-generated lyrics
- User mentions "write a song", "music generation", "BGM", "background music", "lyrics"
Environment Variables
Two authentication methods are supported (gateway takes priority):
Option 1: API Gateway (recommended)
ARK_SKILL_API_BASE— API gateway base URLARK_SKILL_API_KEY— API gateway authentication key
Option 2: Direct AK/SK
VOLCENGINE_ACCESS_KEY— AccessKey IDVOLCENGINE_SECRET_KEY— AccessKey Secret- How to obtain: Volcengine Console → Account → Key Management → Create Key
Usage
- Determine user intent and select the mode (
song/bgm/lyrics). cdto the skill directory:skills/byted-music-generate.- Run the script. The script polls the API internally and may take several minutes to complete (typically 1–5 minutes for song/bgm).
- Monitor execution: If the runtime environment moves the command to background, you MUST periodically (every 10 seconds) read the terminal output to check whether the script has finished. The script prints polling progress to stderr and outputs a single JSON line to stdout upon completion.
- Once completed, return the
audio_urlorlyricsfrom the JSON output to the user.
Three Modes
1. song — Vocal Song
User provides lyrics (Lyrics) or a text prompt (Prompt) to generate a vocal song.
# With text prompt
python scripts/music_generate.py song --prompt "A song about summer at the beach" --genre Pop --gender Female
# With lyrics
python scripts/music_generate.py song --lyrics "[verse]\nMoonlight on the windowsill\nMemories flowing like water\n[chorus]\nYou are my moonlight" --genre Folk --mood "Sentimental/Melancholic/Lonely"
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

byted-music-generate is a skill published in the GitHub repository bytedance/agentkit-samples (450 stars, last pushed 5d ago), licensed Apache-2.0. It adds 62 tokens to every session and 1,954 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
