Security Scan

The skill's files and runtime instructions are consistent with a local CSV analysis tool: it does not request credentials or network access, but it does write logs/data under your home directory and has a small mismatch between declared environment requirements and script behavior.

Purpose & Capability

Name/description match included scripts and SKILL.md: tools for analysis, charting, filtering, merging, cleaning, conversion and HTML reports. No unrelated credentials, binaries, or external services are requested.

Instruction Scope

SKILL.md prompts and the two scripts stick to CSV processing and report generation. One point to note: the embedded Python analyzer expects a file path via sys.argv or CSV_FILE environment variable, but the wrapper heredoc does not pass argv — so the behavior falls back to CSV_FILE. CSV_FILE is not declared in requires.env, creating a small inconsistency (functional bug/risk that the agent may rely on an undeclared env var).

Install Mechanism

No install spec or external downloads; this is instruction + script-only, so nothing is fetched from arbitrary URLs and no archives are extracted.

Credentials

The skill declares no required environment variables or credentials. The scripts optionally respect CSV_ANALYZER_CN_DIR and (in practice) may read CSV_FILE if present — CSV_ANALYZER_CN_DIR is reasonable for configuring data storage; CSV_FILE is not declared and should be considered optional/undeclared.

Persistence & Privilege

The skill is not always-enabled and runs only when invoked. It creates a data directory under $XDG_DATA_HOME or $HOME/.local/share/csv-analyzer-cn and writes history.log and data.log there — normal for a local tool, but it does persist data and logs on disk which may include user-provided CSV contents.

Assessment

This skill appears to do exactly what it claims: local CSV analysis and report generation with no network calls or secret access. Before installing: (1) be aware it will create and write files under ~/.local/share/csv-analyzer-cn (or $XDG_DATA_HOME) and keep history/logs — avoid using it on CSVs containing secrets you don't want saved; (2) note a small implementation quirk: the analyze subcommand's embedded Python expects a filename via sys.argv or the CSV_FILE env var but the wrapper doesn't pass argv, so you may need to set CSV_FILE or call the script with the correct invocation; (3) review the included scripts yourself if you need stronger assurance; (4) if you plan autonomous agent use, remember the skill can write files locally — consider running in an isolated environment for sensitive data.
