forge-cms

forge-cms is a skill for Claude Code from ForgeyClap/claude-forge. It costs 0 tokens per session (1,578 once invoked), scanned A, original, MIT.

A playbook for building and changing content-management systems such as WordPress and headless CMS platforms.

In plain words
What is it for?
Use it for WordPress themes, plugins, custom content types, WP-CLI work, headless schemas, migrations, webhooks, and editor-safe content workflows.
Why use it?
It helps protect live content by defining the content model, keeping editor changes separate from code, and requiring backups before risky changes.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

forge-cms 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 20d 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.

Forge playbook — CMS (WordPress · headless)

A CMS is a content-model + editor-safety + migration domain sitting on top of a live database and uploads. The rendered front-end defers to forge-website (real content, responsive, a11y, SEO, performance); the API/secret/webhook plumbing defers to forge-integration; this file governs the content model, the CMS-specific attack surface, and migration/backup safety. The single most important rule is back up before you change anything — CMS mistakes hit live content and are often irreversible without a backup. Honest limit: Forge cannot run a live WordPress/MySQL install or take a real DB/uploads backup unless the environment provides PHP + MySQL + WP-CLI (opt-in, owner-side) — mark those steps not-run when the runtime is absent.

Hard rules (non-negotiable)

  • Content model first. Define post types / fields / taxonomies (WordPress custom post types + ACF/meta) or the headless schema (Contentful/Sanity/Strapi/Payload content types) before templating. Editors must be able to change content without touching code — no business copy hardcoded in the theme.
  • No secrets in the theme or repo. DB credentials, salts, API tokens, and SMTP creds live in env / wp-config.php (via env constants), never committed. wp-config.php with real values is never in git; headless API tokens are server-side only.
  • WordPress output/input safety. Escape on output (esc_html / esc_attr / esc_url / wp_kses), sanitize on input (sanitize_text_field etc.), and use $wpdb->prepare for every query — WP is a large XSS/SQLi surface. Nonces (wp_verify_nonce) + capability checks (current_user_can) on every state-changing action. Never edit WordPress core; extend via a child theme and properly enqueued scripts/styles (wp_enqueue_*). Vet third-party plugins (source, active maintenance, known CVEs) and pin versions.
  • Headless token + webhook hygiene. Read/write API tokens stay server-side and are never shipped to the browser; preview/draft tokens are scoped and short-lived; CORS is locked to known origins; CMS→build webhooks verify their signature before triggering a rebuild (defer to forge-integration).
  • Backup before change; reversible, staged migrations. Take a full DB + uploads backup before any plugin/theme/core update or content migration. Migrations run on staging first and are reversible. Serialized data (WP wp_options, meta) must be changed with a serialization-safe tool — wp search-replace (WP-CLI), never a raw SQL find/replace, which corrupts serialized PHP and silently breaks the site.
  • Keep it patched; least privilege. Core, themes, and plugins stay on security-patched versions; user roles follow least privilege (no gratuitous Administrators).
  • Performance + accessibility are gates, not extras. Page/object caching, image optimization, minimal plugin bloat, lazy-loading; and a11y on rendered output (semantic markup, alt text, heading order, contrast) — the CMS must emit accessible, fast HTML.

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.
