Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.01140 |
| Opus 5 | $0.00030 | $0.00570 |
| Sonnet 5 | $0.00012 | $0.00228 |
| Haiku 4.5 | $0.00006 | $0.00114 |
Grade A, and why
wp-playground scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to wp-playground — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

wp-playground is a skill published in the GitHub repository ihatesea69/HieuNghi-AI-Skills (3 stars, last pushed 6mo ago), licensed MIT. It adds 60 tokens to every session and 1,140 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to wp-playground, differing in 0 lines, and is treated as a copy.
