Security checks for vulnerabilities and agentic risk
This is a straightforward local CSS flexbox generator, with disclosed local storage and no evidence of hidden network, credential, or persistence behavior.
Before installing, be aware that saved layouts are kept in ~/.flex/data.jsonl and exports using --output can overwrite an existing file at the chosen path. Use stdout or a dedicated CSS export path if you want to avoid accidental replacement.
The skill advertises shell execution and write access to a persistent user directory but does not declare any explicit tool scope such as allowed-tools or permissions. That creates a trust and containment gap: an agent may invoke filesystem-writing behavior without a clear policy boundary, increasing the chance of unintended file modification or broader command execution than expected.
The skill stores layout data persistently in ~/.flex/data.jsonl, which creates session persistence across runs. While expected for a CLI layout tool, persistent storage can retain sensitive project names, layout metadata, or user-supplied content longer than intended, and that data may later influence agent behavior or be read by other local processes.
# Flex — CSS Flexbox Layout Generator
A CLI tool for generating CSS Flexbox layouts. Create flex containers, configure alignment, justify, wrap, gap, and order properties, then export production-ready CSS code.
## Prerequisites
The export command writes directly to a user-supplied path with mode 'w', which will silently truncate and overwrite any existing file the current user can access. In an agent/CLI skill context, that is dangerous because an unintended or manipulated --output value can destroy user data or overwrite project files without any confirmation or path restriction.
No suspicious patterns detected.
