configurationConfigure playground behavior through Config object, query parameters, EmbedOptions, editor settings, processors, external resources, and custom settings.
Configuration is an agent skill from live-codes/livecodes. Configure playground behavior through Config object, query parameters, EmbedOptions, editor settings, processors, external resources, and custom settings. Load this skill when setting up project content, configuring CSS processors, or customizing display.
Its SKILL.md is about 4.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: A Code Playground That Just Works! The licence is MIT.
Read from SKILL.md and the folder at commit 5754e89. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
livecodes.iocdn.jsdelivr.netFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Configuration loads about 4.5k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 726 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
The full file from live-codes/livecodes at commit 5754e89, republished under its MIT licence (© live-codes). 726 words, ~4,521 tokens.

Configure playground behavior through Config object, query parameters, EmbedOptions, editor settings, processors, external resources, and custom settings. Configuration is an agent skill from live-codes/livecodes. Configure playground behavior through Config object, query parameters, EmbedOptions, editor settings, processors, external resources, and custom settings.
Run `npx skills add live-codes/livecodes --skill configuration -a claude-code`. Or copy the skill folder (.agents/skills/livecodes/configuration in live-codes/livecodes) into .claude/skills/configuration in your project. Claude Code loads it when a task matches its description.
Run `npx skills add live-codes/livecodes --skill configuration -a codex`. Or copy the skill folder (.agents/skills/livecodes/configuration in live-codes/livecodes) into .agents/skills/configuration in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add live-codes/livecodes --skill configuration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/configuration, .gemini/skills/configuration, .github/skills/configuration and .opencode/skills/configuration in your project.
SKILL.md names no scripts, command-line tools or credentials: Configuration is instructions for the agent only.
SKILL.md names 2 domains. In commands or code: livecodes.io and cdn.jsdelivr.net; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Configuration is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 4.5k tokens (SKILL.md is roughly 18k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Configuration: Parameters (thedaviddias/Front-End-Checklist, 74k stars), Playground (Arize-ai/phoenix, 12k stars), Vuetify Playground (vuetifyjs/vuetify, 41k stars) and Object Storage (sickn33/agentic-awesome-skills, 47k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
live-codes (a GitHub organization) maintains it in live-codes/livecodes, which has 1,512 GitHub stars. The repository holds 15 skills in this directory. The repository was last updated on October 6, 2026.
