Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
What it does
This skill enables AI agents to compare and leverage the strengths of regular expressions (regex) and large language models (LLMs) for structured text processing. It helps in identifying when regex is more efficient, such as for pattern matching, versus when LLMs excel at understanding context or generating complex outputs.
When to use it
- Extracting specific patterns from unstructured logs or data where regex can be faster and more precise.
- Parsing semi-structured text like JSON or XML where both regex and LLMs may be used depending on complexity.
- Generating structured outputs (e.g., tables, forms) from free-form text when an LLM's contextual understanding is required.
Key capabilities
- Pattern matching using regular expressions for precise data extraction.
- Context-aware parsing with large language models for complex or ambiguous text structures.
- Decision-making on which method to use based on input complexity and desired output format.
Example prompts
- "Extract all email addresses from this log file using regex."
- "Parse the user feedback into a structured table, using an LLM if needed."
- "Compare the efficiency of regex versus an LLM for extracting dates from unstructured text."
Tips & gotchas
- Regex is best suited for repetitive, pattern-based tasks, while LLMs are better for nuanced or ambiguous content.
- Ensure your input data is clean and consistent to maximize accuracy with both methods.
