Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Drop-in inspector panel for any json-render app. Use when the user wants to debug a generative UI, inspect the spec tree, edit state at runtime, see dispatched actions, follow stream patches live, browse a catalog, or pick DOM elements to find their spec keys. Triggers include "add devtools", "debug json-render", "inspect the spec", "why is this element not rendering", "see the state at runtime", or requests to tap streams / capture action logs for `@json-render/devtools`.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'json-render-devtools' ] || [ -L ~/.agents/skills/'json-render-devtools' ]; then echo 'A skill folder named json-render-devtools already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/b-open-io/prompts' "$d" && git -C "$d" checkout --quiet 'f4b302aadb0c99023b03e1f1b38ffed3697fbedf' -- 'modules/mcp-dev/.agents/skills/json-render-devtools' && mkdir -p ~/.agents/skills && cp -R "$d"/'modules/mcp-dev/.agents/skills/json-render-devtools' ~/.agents/skills/'json-render-devtools' && 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/'json-render-devtools' ~/.claude/skills/'json-render-devtools' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
