Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/firecrawl/agent-skills --skill wp-playground- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads wp-playground automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

The instructions your agent reads when the skill is triggered.
WordPress Playground
When to use
- Spin up a disposable WordPress to test a plugin/theme without full stack setup.
- Run or iterate on Playground Blueprints (JSON) locally.
- Build a reproducible snapshot of a site for sharing or CI.
- Switch WP/PHP versions quickly to reproduce issues.
- Debug plugin/theme code with Xdebug in an isolated Playground.
Inputs required
- Host machine readiness: Node.js ≥ 20.18,
npm/npxavailable. - Project path to mount (
--auto-mountor explicit mount mapping). - Desired WP version/PHP version (optional; defaults to latest WP, PHP 8.3).
- Blueprint location/URL if running a blueprint.
- Port preference if 9400 conflicts.
- Whether Xdebug is needed.
Procedure
0) Guardrails
- Playground instances are ephemeral and SQLite-backed; never point at production data.
- Confirm Node ≥ 20.18 (
node -v) before running CLI. - If mounting local code, ensure it is clean of secrets; Playground copies files into an in-memory FS.
1) Quick local spin-up (auto-mount)
cd <plugin-or-theme-root>
npx @wp-playground/cli@latest server --auto-mount
- Opens on http://localhost:9400 by default. Auto-detects plugin/theme and installs it.
- Add
--wp=<version>/--php=<version>as needed. - For classic full installs already present, add
--skip-wordpress-setupand mount the whole tree.
2) Manual mounts or multiple mounts
- Use
--mount=/host/path:/vfs/path(repeatable) when auto-mount is insufficient (multi-plugin, mu-plugins, custom content). - Mount before install with
--mount-before-installfor bootstrapping installer flows. - Reference:
references/cli-commands.md
3) Run a Blueprint (no server needed)
npx @wp-playground/cli@latest run-blueprint --blueprint=<file-or-url>
- Use for scripted setup/CI validation. Supports remote URLs and local files.
- Allow bundled assets in local blueprints with
--blueprint-may-read-adjacent-fileswhen required. - See
references/blueprints.mdfor structure and common flags.
4) Build a snapshot for sharing
npx @wp-playground/cli@latest build-snapshot --blueprint=<file> --outfile=./site.zip
- Produces a ZIP you can load in Playground or attach to bug reports.
5) Debugging with Xdebug
- Start with
--xdebug(or--enable-xdebugdepending on CLI release) to expose an IDE key, then connect VS Code/PhpStorm to the host/port shown in CLI output. - Combine with
--auto-mountfor plugin/theme debugging. - Checklist:
references/debugging.md
6) Version switching
- Use
--wp=to pin WP (e.g., 6.9.0) and--php=to test compatibility. - If feature depends on Gutenberg trunk, prefer the latest WP release plus plugin if available; Playground images track stable WP plus bundled Gutenberg.
7) Browser-only workflows (no CLI)
- Launch quick previews with URL fragments or query params:
- Fragment:
https://playground.wordpress.net/#<base64-or-json-blueprint> - Query:
https://playground.wordpress.net/?blueprint-url=<public-url-or-zip>
- Fragment:
- Use the live Blueprint Editor (playground.wordpress.net) to author blueprints with schema help; paste JSON and copy a shareable link.
Verification
- Verify mounted code is active (plugin listed/active; theme selected).
- For blueprints/snapshots, re-run with
--verbosity=debugto confirm steps executed. - Run targeted smoke (e.g.,
wp plugin listinside Playground shell via browser terminal if exposed) or UI click-path.
Failure modes / debugging
- CLI exits complaining about Node: upgrade to ≥ 20.18.
- Mount not applied: check path, use absolute path, add
--verbosity=debug. - Blueprint cannot read local assets: add
--blueprint-may-read-adjacent-files. - Port already used:
--port=<free-port>. - Slow/locked UI: disable
--experimental-multi-workerif enabled; or enable it to improve throughput on CPU-bound runs.
Escalation
- If PHP extensions or native DB access are required, Playground may be unsuitable; fall back to full WP stack or wp-env/Docker.
- For browser-only embedding or VS Code extension specifics, consult the upstream docs: https://wordpress.github.io/wordpress-playground/
