# Craft Plugins > 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 - Skill: `majiayu000/craft-plugins` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds add majiayu000/craft-plugins` - Raw SKILL.md: https://api.skillmd.com/api/skills/majiayu000/craft-plugins/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Marketing & Growth - Author: majiayu000 (https://skillmd.com/u/majiayu000) - Updated: 2026-09-09 - Page: https://skillmd.com/skills/majiayu000/craft-plugins --- # 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/.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/.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 | Reference | Plugin (vendor) | Primary altitude | Key surface | |-----------|-----------------|------------------|-------------| | `references/formie.md` | Formie (verbb) | Front-end **and** back-end | Form rendering (one-line/granular), theme config; **programmatic form creation in a content migration**, forms as DB elements (not project config), cross-environment deployment, multi-site/static translation, File Upload volume + file renaming, notification attachments, captcha & caching | | `references/seomatic.md` | SEOmatic (nystudio107) | Front-end + config | Meta cascade, Twig get/set API, JSON-LD, custom element SEO bundles, sitemaps, GraphQL | | `references/blitz.md` | Blitz (putyourlightson) | Mixed (front-end + ops) | Refresh modes, Twig dynamic content, driver architecture (storage/purger/deployer), Nginx rewrite, Cloudflare integration | | `references/feed-me.md` | Feed Me (craftcms) | **Back-end / ops** | Data import from XML/JSON/CSV, field mapping, duplicate handling, CLI automation, scheduled imports | | `references/imager-x.md` | Imager-X (spacecatninja) | Front-end + config | Advanced image transforms, batch generation, named presets, effects, optimizers, external storage | | `references/image-optimize.md` | ImageOptimize (nystudio107) | Front-end + field config | OptimizedImages field, `imgTag()`/`pictureTag()` builders, loading strategies, transform methods, console commands | | `references/ckeditor.md` | CKEditor (craftcms) | Mixed (field config + front-end) | Field settings (toolbar, headings, image mode), nested entries with chunk rendering and value helpers, link configuration, GraphQL Mode, ES-module custom plugins, HTML Purifier, Redactor migration | | `references/sprig.md` | Sprig (putyourlightson) | Front-end | Reactive Twig components (htmx), live search, load more, pagination, filtering, form submissions without JS | | `references/element-api.md` | Element API (craftcms) | **Back-end / config** | JSON API via config file, Fractal transformers, endpoint routing, pagination, caching | | `references/retour.md` | Retour (nystudio107) | Ops / config | Redirect types (exact/regex), 404 tracking, CSV import, auto slug-change redirects, config | | `references/navigation.md` | Navigation (verbb) | Front-end | Node querying, custom rendering, active states, custom fields on nodes, GraphQL | | `references/hyper.md` | Hyper (verbb) | Front-end + field config | Link types, `getLinkAttributes()`, `getText()`, single/multi-link, element access, button atom integration | | `references/colour-swatches.md` | Colour Swatches (craftpulse) | Mixed | Palette config, multi-colour swatches, Tailwind class mapping, Twig model API | | `references/password-policy.md` | Password Policy (craftpulse) | **Back-end / config** | Validation rules, HIBP check, retention/expiry, console commands, recommended settings | | `references/typogrify.md` | Typogrify (nystudio107) | Front-end | `\|typogrify`, `\|widont`, `\|truncateOnWord`, smart quotes, widow prevention | | `references/cache-igniter.md` | Cache Igniter (putyourlightson) | Ops | GlobalPing warmer, geographic locations, refresh delay, Blitz companion | | `references/knock-knock.md` | Knock Knock (verbb) | Ops / config | Staging password protection, environment-aware config, URL exclusions | | `references/timeloop.md` | Timeloop (craftpulse) | Mixed | Repeating date field, `craft.timeloop` variable API, `recurringDates()` function, GraphQL, period frequencies | | `references/elements-panel.md` | Elements Panel (putyourlightson) | Dev tooling | Debug toolbar panels for element population counts, duplicate detection, eager-loading opportunities | | `references/sherlock.md` | Sherlock (putyourlightson) | Ops / config | Security scanning, HTTP headers, CMS config checks, scheduled scans, IP restriction, monitoring | | `references/embedded-assets.md` | Embedded Assets (spicyweb) | Mixed | oEmbed as first-class assets, `craft.embeddedAssets.get()`, iframe customization, GraphQL | | `references/amazon-ses.md` | Amazon SES (putyourlightson) | **Back-end / config** | SES mail transport adapter, AWS credential config, SNS bounce tracking (no Twig API) | | `references/vite.md` | Vite (nystudio107) | Front-end + buildchain | `craft.vite.*` Twig API (`script`, `register`, `entry`, `asset`, `integrity`, `inline`, `includeCriticalCssTags`, `devServerRunning`), `vite.php` config keys. Buildchain/`vite.config.ts` detail in the `craft-site` skill's `references/vite-buildchain.md` | ## Companion skills - **`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.
