Security Scan

The skill is an instruction-only poster generator whose requested actions and resources match its description; it asks for no credentials or installs and behaves as expected for image-prompt composition and synthesis.

Purpose & Capability

Name/description (dark 9:16 poster with handwritten marker style) match the actual instructions: build structured prompts and call image_synthesize. No unrelated credentials, binaries, or installs are requested.

Instruction Scope

Runtime instructions are focused on composing prompts and calling image_synthesize, saving output to /workspace and returning it via the 'message' tool (channel=feishu). This is coherent, but the doc assumes platform tools (image_synthesize and message) exist and instructs sending results via a specific channel — confirm you trust the agent's messaging integration and storage of /workspace artifacts. There is a minor internal guidance tension: style-guide advises 'do not put Chinese in prompts' while the skill expects Chinese poster text; this is explainable but worth noting.

Install Mechanism

Instruction-only skill with no install spec and no code files — lowest-risk install surface. Nothing is downloaded or written by an installer.

Credentials

The skill requests no environment variables, credentials, or config paths. All declared requirements are proportional to its purpose.

Persistence & Privilege

always:false and no persistent install actions. The skill does not request permanent presence or elevated privileges and does not modify other skills or system configs.

Assessment

This skill appears internally consistent and does what it says: it assembles English prompts for a dark 9:16 poster style, calls the platform image_synthesize tool, writes an image to /workspace, and sends it via the agent's messaging tool. Before installing, confirm you are comfortable with: (1) the agent having access to the platform image_synthesize and message tools (it will send images to the configured channel, here mentioned as Feishu); (2) generated artifacts being written to /workspace (check your platform's retention and visibility policies); and (3) any brand/logo text the skill may generate — you should verify copyright/trademark use and replace AI-generated Chinese text with vetted fonts for production. If any of these platform integrations are untrusted in your environment, restrict or review them before enabling the skill.
