description: "Index and router for plugin-specific Craft CMS 5 guidance — configuration, Twig API, PHP/programmatic API, migrations, deployment, and pitfalls for the third-party plugins this pack documents. This skill exists so a plugin task is discoverable regardless of altitude: front-end (Twig/styling), back-end (PHP, content migrations, events), content modeling, or deployment all route here. Triggers whenever a task names one of these plugins in ANY context — build, configure, style, render, query, import, migrate, deploy, translate, cache, or debug: Formie (forms, form builder, submissions, File Upload field, form in a migration, form notifications), SEOmatic (meta, sitemaps, JSON-LD, SEO field), Blitz (static/page caching, purge, refresh), Feed Me (import XML/JSON/CSV feeds, scheduled import), Imager-X (image transforms, srcset, optimizers), ImageOptimize (OptimizedImages field, responsive images), CKEditor (rich text field, nested entries), Sprig (reactive components, htmx), Element API (JSON API endpoints), Retour (redirects, 404 tracking), Navigation (nav menus, nodes), Hyper (link field), Colour Swatches (colour palette field), Password Policy (password rules, HIBP), Typogrify (typography filters), Cache Igniter (cache warming), Knock Knock (staging password), Elements Panel (debug toolbar, N+1), Sherlock (security scanning), Amazon SES (email transport, SES, SNS bounce), Embedded Assets (oEmbed assets), Timeloop (recurring dates), Vite (craft.vite.*, asset bundling). Always use when a task mentions one of these plugins by name, even when the work is PHP/migration/deployment rather than Twig — read references/<plugin>.md before implementing. Do NOT trigger for Craft core APIs with no plugin named (craftcms), front-end template architecture in general (craft-site), or content modeling in general (craft-content-modeling) — those skills cross-link here when a specific plugin is involved."

# Craft CMS 5 — Plugin References (Index & Router)

This skill is a **router**, not a tutorial. Its job is to make per-plugin
guidance discoverable from any task framing — front-end, back-end PHP, content
migration, deployment, or config — and point you at the right reference file.

Each plugin's curated reference lives in `references/<plugin>.md` and covers
configuration, the Twig and/or PHP API, and the real-world pitfalls. Read the
matching reference **before** implementing anything plugin-specific.

## How to use this skill

1. Identify the plugin(s) named in the task (by name, package, or feature).
2. Open the matching `references/<plugin>.md` from the table below.
3. If the task is back-end (PHP, content migration, events, deployment), check
   the reference's back-end / programmatic sections specifically — several
   plugins (Formie, Feed Me, Element API, Amazon SES) are primarily or
   substantially back-end despite historically living under the front-end skill.

## Routing table

- **`craftcms`** — for the Craft core APIs a plugin task builds on: element saving, events, migrations, queue jobs, field-value storage. Load alongside this skill for any plugin **PHP/migration** work.
- **`craft-site`** — for front-end template architecture the plugin output slots into (components, layouts, image presets). Load alongside this skill for plugin **rendering/styling** work.
- **`craft-content-modeling`** — when the plugin interacts with sections, fields, volumes, or multi-site propagation.
- **`craft-cloud` / `servd`** — when the plugin task involves deployment, edge caching, or ephemeral-filesystem constraints.
