Seedream 图片生成

Seedream 图片生成 - 火山引擎方舟大模型服务平台图片生成 API。支持文生图、图生图、多图融合、组图生成等多种模式。

Security Scan

The skill's stated purpose and requested credential (ARK_API_KEY) match the Seedream/Volcengine image-generation API, but the runtime instructions expect local Python scripts that are not included—this mismatch is suspicious and needs clarification before installing.

Purpose & Capability

Name/description correspond to Volcengine Seedream image-generation and the single required env var ARK_API_KEY and python3 binary are appropriate for that purpose. However, the SKILL.md assumes a local script at {baseDir}/scripts/seedream.py which is not provided in the package, so the bundle is incomplete.

Instruction Scope

Instructions tell the agent to run python3 {baseDir}/scripts/seedream.py with various flags and to read ARK_API_KEY. Because there are no code files, the instructions refer to files that don't exist in the skill—this is a substantive scope/integrity problem. Also, the README suggests passing the API key on the command line (exposes it via process lists) and enables network calls (expected for an API client) but the exact network endpoints and behavior of the missing script are unknown.

Install Mechanism

The only install step is a brew install of the python formula to provide python3, which is reasonable and low-risk for a Python-based CLI. No downloads from unknown URLs or archive extraction are present.

Credentials

Only ARK_API_KEY is required and declared as the primary credential, which is proportionate for a cloud image-generation API. No unrelated credentials or config paths are requested.

Persistence & Privilege

The skill does not request always:true or other elevated persistence. It is user-invocable and allows autonomous invocation (the platform default); this is expected for skills that make network API calls.

What to consider before installing

This skill appears to be an instruction wrapper for Volcengine's Seedream image API and appropriately asks for ARK_API_KEY and python3, but the SKILL.md expects a local script ({baseDir}/scripts/seedream.py) which is not included in the package. Before installing or running it, ask the publisher for the missing script or the real implementation, and verify its source. Do not paste your ARK_API_KEY into command-line arguments (use environment variables or secure config) because command-line args can be visible to other users/processes. Confirm the script makes HTTPS calls to the official Volcengine endpoints and inspect its code for any unexpected file access or data exfiltration. Because this is an instruction-only skill with no code to audit, treat the missing script as an integrity gap—if you cannot obtain and review that code from a trusted source, avoid installing or running the skill.
