text-editor-from-scratch

100 / 100 · Low risk

Fine to try.

By yanacuti1121/Yana-AI (GitHub) · coding · 13 stars · scanned at commit 54d4aa9

Use when building a terminal or GUI text editor from first principles — buffer data structures, cursor handling, raw-mode terminal rendering, undo/redo. Not for configuring an existing editor. Triggers on: 'build a text editor', 'implement a text buffer', 'gap buffer vs piece table', 'terminal raw mode editor', 'write my own vim/nano clone', 'undo redo implementation for editor'.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'text-editor-from-scratch' ] || [ -L ~/.agents/skills/'text-editor-from-scratch' ]; then echo 'A skill folder named text-editor-from-scratch already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/yanacuti1121/Yana-AI' "$d" && git -C "$d" checkout --quiet '54d4aa9fa3241319f4d37212bd23826658bf6bed' -- '.claude/skills/text-editor-from-scratch' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/text-editor-from-scratch' ~/.agents/skills/'text-editor-from-scratch' && 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/'text-editor-from-scratch' ~/.claude/skills/'text-editor-from-scratch' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
