Hmi

Human-machine interface design tool

Security Scan

The skill is an instruction-only local CLI that stores data under ~/.hmi and its requirements and behavior align with its description.

Purpose & Capability

Name/description (HMI design tool) align with the included CLI script and commands. The script implements add/list/search/remove/export/stats/config functionality and only touches a local data directory (default ~/.hmi). Nothing requested by the skill (no credentials, no external services) is unexpected.

Instruction Scope

SKILL.md instructs the agent to run scripts/script.sh <command>, which is exactly the included script. The script only reads/writes files under the DATA_DIR (default ~/.hmi) and prints to stdout. It does not access other system config, credentials, or network endpoints.

Install Mechanism

No install spec — instruction-only with an included shell script. No downloads or package installs are requested, and the script is local, so nothing arbitrary is fetched or written during install.

Credentials

No required environment variables or credentials. One optional env var (HMI_DIR) controls the data directory — proportional to the stated functionality.

Persistence & Privilege

always is false and the skill does not request persistent elevated privileges or modify other skills or system-wide agent settings. It will create/modify files under the user's ~/.hmi directory (expected behavior for a CLI tool).

Assessment

This skill will execute a local shell script and store data under ~/.hmi (data.jsonl and config.txt). There are no network calls or credential requests. If you plan to install/run it, review scripts/script.sh yourself (it is small and readable) and be aware it will write and edit files in your home directory. If you prefer isolation, run it in a sandbox or container.
