Rxtool

Test, extract, replace, split, and explain regular expressions. Use when asked to test a regex pattern, extract matches from text, do regex replacements, spl...

Security Scan

The skill is a small, self-contained regex utility whose code, instructions, and requirements align with its stated purpose and do not request credentials or external installs.

Purpose & Capability

Name/description (regex testing/extraction/replacement/explanation) match the included code and runtime instructions. No unrelated environment variables, binaries, or config paths are requested. The presence of both rxtool.py and scripts/rxtool.py appears to be a packaging duplication but is consistent with the stated CLI usage.

Instruction Scope

SKILL.md instructs running the provided script(s) with pattern and text or via stdin. The instructions only reference regex patterns, text input, flags, and JSON output; they do not read or transmit unrelated files, environment variables, or external endpoints.

Install Mechanism

There is no install spec and all code is included in the bundle. No downloads, package managers, or archive extraction are used, which minimizes installation risk.

Credentials

The skill requires no environment variables, credentials, or privileged config paths. Runtime behavior reads stdin or accepts inline text only, which is proportional to a regex tool.

Persistence & Privilege

The skill is not always-enabled and does not request persistent system changes or modify other skills. It uses standard CLI invocation and has no autonomous persistence beyond normal skill behavior.

Assessment

This skill appears coherent and self-contained: it runs local Python code to test/extract/replace/split/explain regexes and does not contact networks or ask for credentials. Things to consider before installing or running: (1) the package contains two identical script files (harmless but redundant); (2) be cautious when running untrusted regexes or feeding untrusted patterns into your environment — complex regexes can cause excessive CPU usage (ReDoS/catastrophic backtracking) or large outputs; and (3) if you plan to use it on sensitive data, remember it prints matches to stdout — avoid piping secrets into tools unless you control where the output goes. If you need the maintainer's identity or a homepage for auditability, request that before wide deployment.

Regex Swiss army knife — test, extract, replace, split, explain.

Commands

# Test a pattern against text
python3 scripts/rxtool.py test '(\d+)-(\d+)' "order-123-456"

# Extract all matches
python3 scripts/rxtool.py extract '\b\w+@\w+\.\w+\b' "email me at [e-mail]"

# Extract with JSON output
echo "text" | python3 scripts/rxtool.py extract '\w+' --json

# Replace matches
python3 scripts/rxtool.py replace '\d+' 'NUM' "got 42 items and 7 boxes"

# Split by pattern
python3 scripts/rxtool.py split '[,;\s]+' "a, b; c d"

# Explain a regex
python3 scripts/rxtool.py explain '(?P<year>\d{4})-(?P<month>\d{2})'

Features

• Group capture (numbered and named)
• Case-insensitive (-i), multiline (-m), dotall (-s) flags
• Stdin pipe support
• JSON output for extraction
• Regex explanation with component breakdown
