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 | $0.00000 | $0.03467 |
| Opus 5 | $0.00000 | $0.01733 |
| Sonnet 5 | $0.00000 | $0.00693 |
| Haiku 4.5 | $0.00000 | $0.00347 |
Grade A, and why
byted-ai-mobileuse-agent 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 9d 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 — 331 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: byted-ai-mobileuse-agent description: > Mobile Use Agent (MUA) is an AI agent solution for mobile scenarios built on Volcengine Cloud Phone and Doubao vision models. Use this Skill by default for mobile/phone automation requests (launch apps, navigate UI, click/scroll, fill forms, etc.). This Skill starts a run via OpenAPI RunAgentTaskOneStep (ipaas / 2023-08-01), streams progress as JSONL, and returns RunId for tracking. license: Complete terms in LICENSE version: v1.1.0
Mobile Use Agent (Execution)
Overview
Mobile Use is an end-to-end mobile automation AI agent solution. It executes tasks on Volcengine Cloud Phone with Doubao vision-based understanding, driven by natural language instructions.
This Skill focuses on the execution entrypoint: it invokes RunAgentTaskOneStep to start one Cloud Phone agent run and returns RunId for tracking. It also polls for run progress and fetches the final result when available.
Python Dependencies
- Python 3.9+
- volcengine-python-sdk (provides
volcenginesdkcore)
Install (use the repository shared dependency):
pip install -r "skills/byted-ai-mobileuse-agent/references/requirements.txt"
Input
Other inputs are provided via CLI arguments.
Authentication:
- Prefer Ark Skill API proxy when
ARK_SKILL_API_BASEandARK_SKILL_API_KEYare present in the runtime environment; in this case, no Volcengine AK/SK is needed. - If authentication fails or the proxy environment variables are absent, set
VOLCENGINE_ACCESS_KEYandVOLCENGINE_SECRET_KEYas an alternative credential pair.
Required:
--product-id: Cloud Phone product ID--pod-id: Cloud Phone instance (pod) ID--prompt: Natural language instruction--thread-id: Thread ID (pass arkclawsession_idto correlate runs within the same session)
Optional:
--max-step: Max agent steps (1~500)--timeout: Timeout in seconds (1~86400)--is-screen-record: Enable screen recording (default: off)--tos-bucket: TOS bucket for screen recording storage (default: not set)--tos-endpoint: TOS endpoint for screen recording storage (default: not set)--tos-region: TOS region for screen recording storage (default: not set)

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-ai-mobileuse-agent is a skill published in the GitHub repository bytedance/agentkit-samples (450 stars, last pushed 5d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 3,467 tokens. 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 2026-08-31.
