regex-vs-llm-structured-text
80 / 100 · Low risk
Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By affaan-m/ECC (GitHub) · coding · 300,508 stars · scanned at commit d2ef268
Decision framework for parsing structured text (quizzes, forms, invoices, receipts, tables) with a hybrid regex-first pipeline — regex extraction handles 95%+ cheaply, a confidence scorer flags low-confidence items, and an LLM validator fixes only the edge cases. Use when choosing between regex and LLM for text extraction, building a cheap document parser, or optimizing extraction cost and accuracy.
Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'regex-vs-llm-structured-text' ] || [ -L ~/.agents/skills/'regex-vs-llm-structured-text' ]; then echo 'A skill folder named regex-vs-llm-structured-text already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/affaan-m/ECC' "$d" && git -C "$d" checkout --quiet 'd2ef2680594f9a17526a6e1a2e18b3d242c5d17b' -- 'pi/core/skills/regex-vs-llm-structured-text' && mkdir -p ~/.agents/skills && cp -R "$d"/'pi/core/skills/regex-vs-llm-structured-text' ~/.agents/skills/'regex-vs-llm-structured-text' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'regex-vs-llm-structured-text' ~/.claude/skills/'regex-vs-llm-structured-text' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
