poster generator

Generate professional marketing posters, social media graphics, and event flyers using AI-driven templates, customizable text, colors, and batch output in PN...

Security Scan

The skill appears to do what it says (poster generation) but the package metadata omits required Node/npm setup and the docs ask you to install unreviewed npm packages and run commands that may require elevated privileges — review the source and installation steps before trusting it.

Purpose & Capability

The skill's name and documentation describe a Node.js-based poster generator (templates, canvas/sharp/jimp, npm CLI). However the registry metadata lists no required binaries or env vars. That mismatch is an internal inconsistency: a legitimate Node-based skill would normally declare Node/npm as a requirement or include an install spec.

Instruction Scope

SKILL.md instructions stay on-topic (generate posters, templates, fonts, batch runs) and do not explicitly instruct reading unrelated secrets or system files. It recommends cloning a GitHub repo and running npm install, installing system fonts (sudo apt-get), and using axios for network operations — the docs claim 'local processing' but axios implies the code can perform network requests depending on implementation. No explicit exfiltration steps are present, but the skill gives the agent discretion to fetch remote assets.

Install Mechanism

There is no formal install spec in the registry (instruction-only), but the README tells users to npm install -g or git clone from GitHub. Installing npm packages (canvas, sharp, jimp, axios) is common for this functionality, but native modules (canvas, sharp) run build/postinstall scripts and may require system libraries and compilers. Because the skill pulls code from an external GitHub/npm source at install time, review package.json and postinstall scripts before installing.

Credentials

The skill declares no required credentials or env vars (reasonable for offline poster generation). The docs do suggest setting NODE_OPTIONS and using sudo to install fonts or npm -g which require elevated privileges — those are not secrets but are privileged actions. No API keys are requested, but axios in dependencies could be used to fetch remote assets if the implementation does so.

Persistence & Privilege

The skill is not marked always:true and doesn't request special agent-wide privileges. It instructs creating a local config file (.postergenrc.json) which is normal. It does not claim to modify other skills or global agent settings.

What to consider before installing

This skill plausibly implements a poster generator, but there are some red flags you should act on before installing: - Metadata mismatch: the registry lists no required binaries, but the docs require Node.js >=18 and npm packages. Treat the docs as authoritative only after you inspect the code. - Inspect the source: review the GitHub repository (package.json, index/CLI entry, and any postinstall scripts) for network calls, eval/exec usage, or unusual postinstall behavior before running npm install -g. - Check package.json scripts: watch for postinstall, preinstall, or install scripts that run arbitrary commands with your privileges. - Run in a sandbox: if you're unsure, run the tool inside a container or VM, or use npx to avoid global installation. - Watch native modules: canvas/sharp/jimp are native or binary-compiled modules that may require build tools and run native code during install — ensure you trust the package source. - Verify the claim of 'local processing': search the code for axios/fetch/http calls to confirm whether assets or data are sent to external servers. - Avoid providing secrets: the skill does not need API keys for basic features, so do not supply credentials unless you confirm they are necessary and trustworthy. - Use standard safety checks: run `npm audit`, check maintainer reputation, read recent commits, and prefer installing from an official, well-maintained package or verified repository. If you can provide the repository/package.json or the package code, I can scan the scripts and dependencies for risky install-time behavior or network calls to give a higher-confidence assessment.
