77 / 100 · Review before installing
Check before installing. 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
Open plans and HTML artifacts in a local browser canvas where the human annotates elements, chats, and approves or requests changes without leaving the page. Use when presenting a plan for review, or when feedback like "move this, change that" is easier pointed at than typed.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'plan-canvas' ] || [ -L ~/.agents/skills/'plan-canvas' ]; then echo 'A skill folder named plan-canvas 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 "$d" checkout --quiet 'd2ef2680594f9a17526a6e1a2e18b3d242c5d17b' -- 'skills/plan-canvas' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/plan-canvas' ~/.agents/skills/'plan-canvas' && 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/'plan-canvas' ~/.claude/skills/'plan-canvas' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
