Ai Image Gen Skill

AI图片生成技能，使用Gemini生成高质量图片，支持文生图和图生图

Security Scan

The skill's runtime instructions reference an external script and an undeclared GEMINI_API_KEY, which is inconsistent with the declared metadata and may cause the agent to execute code not included with the skill.

Purpose & Capability

The skill claims 'AI图片生成' with Gemini, which fits needing a GEMINI_API_KEY, but the SKILL.md points to /usr/lib/node_modules/openclaw/skills/nano-banana-pro/scripts/generate_image.py — a script that is not part of this skill package and is from a differently named skill (nano-banana-pro). The external dependency is not declared in metadata.

Instruction Scope

Instructions tell the agent to run an absolute path to a local Python script (via 'uv run') and to read reference image files; they also state a required GEMINI_API_KEY. The metadata declares no env vars and no code files. The instructions therefore ask the agent to execute and access resources outside the skill's own bundle and to use an undeclared secret.

Install Mechanism

There is no install spec (instruction-only), which is normally low risk — but here the instructions rely on a specific script path under /usr/lib/node_modules/... that this skill did not install. That could cause execution of arbitrary local code if the referenced script exists and is malicious or unexpected.

Credentials

SKILL.md says '需要 GEMINI_API_KEY' but the skill metadata lists no required env vars or primary credential. Requesting an API key for Gemini is reasonable for an image generation skill, but the omission from declared requirements is an incoherence that prevents informed permissioning and review.

Persistence & Privilege

The skill is not always-enabled and uses normal autonomous invocation defaults. It does not request persistent system-wide privileges in the metadata.

What to consider before installing

Do not install or run this skill as-is. Key issues: SKILL.md instructs running an external script at /usr/lib/node_modules/openclaw/skills/nano-banana-pro/scripts/generate_image.py that is not included, and it requires GEMINI_API_KEY even though metadata lists no env vars. Before proceeding, ask the author for: (1) the actual code or an install spec that creates the referenced script path, (2) an explanation why the skill points to 'nano-banana-pro' instead of its own files, and (3) updated metadata declaring GEMINI_API_KEY. If you must test, inspect the referenced generate_image.py file contents and the 'uv' runner first, run in a sandboxed environment, and ensure the Gemini API key you provide follows least-privilege practices (rotate it, limit scope). Prefer skills with a verifiable source/homepage and included install steps or code.
