WordPress Plugin Builder – Build, Fix & Sell Plugins

WordPress Plugin Factory – Build, Fix & Sell Plugins Turn a plugin idea, feature request, existing codebase, ZIP file, error log, or client brief into a structured WordPress plugin product. WordPress Plugin Factory is an advanced AI development Skill designed to act like a complete senior WordPress product team. It can help you move from: Idea → Architecture → Code → Testing → Security → Documentation → Packaging → Commercial Release instead of generating isolated snippets that still require major development work. The Skill is designed for:

1. WordPress developers
2. Freelancers
3. Agencies
4. SaaS founders
5. WooCommerce developers
6. Plugin sellers
7. CodeCanyon authors
8. WordPress.org publishers
9. Client-project developers
10. Product entrepreneurs
11. White-label software providers
12. Build Complete WordPress Plugins

You can start with something as simple as: Build a booking plugin. Create a WooCommerce warranty PDF plugin. Build a plugin I can sell. Fix this existing plugin. Turn this PHP code into a WordPress plugin. The Skill determines the correct architecture and builds around the actual product goal rather than forcing every project into the same structure. Full Product Architecture Depending on the complexity of the plugin, the Skill can design:

• Plugin bootstrap architecture
• PHP namespaces
• Class/service structure
• Admin modules
• Frontend modules
• WordPress REST API
• AJAX
• Gutenberg blocks
• WooCommerce integrations
• Cron/background jobs
• Database tables
• Schema migrations
• Templates
• JavaScript/React interfaces
• CSS architecture
• Third-party API integrations
• Webhooks
• Licensing
• Update systems
• Diagnostics
• Import/export systems
• Multisite support

It avoids unnecessary enterprise architecture for small plugins while using stronger modular architecture where complexity justifies it. Security Built Into the Architecture Security is treated as a core engineering requirement rather than something added at the end. The Skill checks areas such as:

• Capabilities and permissions
• Nonces
• Input validation
• Sanitization
• Output escaping
• Prepared SQL
• REST authorization
• AJAX authorization
• File upload safety
• Path traversal
• Webhook authentication
• Replay protection
• Secret handling
• Ownership checks
• Database access
• Update mechanisms

It explicitly treats a nonce as not sufficient authorization by itself and requires separate permission/capability checks. WordPress-Native Engineering The Skill prioritizes supported WordPress APIs and extension mechanisms instead of modifying WordPress core or relying on fragile hacks. It can work with:

• Plugin API
• Settings API
• Options API
• Metadata APIs
• REST API
• HTTP API
• Filesystem API
• Cron
• Transients
• Roles and capabilities
• Custom Post Types
• Taxonomies
• Privacy hooks
• Script/style enqueue APIs
• Gutenberg
• WooCommerce public APIs

This helps produce plugins that are easier to maintain and distribute. WooCommerce Plugin Development When WooCommerce is relevant, the Skill can design for:

• WooCommerce CRUD APIs
• HPOS
• Cart and Checkout Blocks
• Store API
• WooCommerce admin
• Product/order workflows
• Subscriptions and payment workflows
• Action Scheduler
• Order lifecycle logic
• Merchant UX
• Marketplace compatibility

It avoids depending on WooCommerce internal APIs where supported public APIs exist. Build for Different Distribution Models The Skill adapts the architecture depending on where the plugin will be used or sold. Supported workflows include: Private / Internal Plugin Optimize for the exact business workflow. Client Delivery Prepare installation, configuration, documentation, diagnostics and safe updates. WordPress.org Free Plugin Focus on directory rules, GPL-compatible distribution, privacy, internationalization, reviewability and Plugin Check readiness. Freemium Design a useful free edition with a maintainable premium architecture. Direct Commercial Sale Add licensing, entitlement, update, documentation and support architecture when required. CodeCanyon Prepare the plugin for Envato-oriented commercial packaging and review. WooCommerce Marketplace Evaluate Woo-specific compatibility, UX, accessibility, HPOS, QIT and submission requirements. SaaS-Connected Plugin Separate the WordPress client plugin from the external SaaS backend and define authentication, retry, privacy, billing and outage behavior. The Skill explicitly routes architecture based on the distribution target. Repair Existing Plugins This is not only a plugin-generation Skill. Upload an existing plugin ZIP, source files, screenshots, error logs or failing code and use the Skill as a repair/debugging system. Its repair workflow is designed to: inspect the supplied evidence locate the root cause identify affected files preserve unrelated working behavior make the smallest safe repair check cross-file dependencies define regression tests return complete updated files when requested update version/changelog when appropriate It avoids redesigning an entire stable plugin just because one isolated feature is broken. Cross-File Integrity Large plugin projects often fail because individually correct files are not correctly connected. The Skill audits relationships between: Classes Namespaces Autoloading Hooks Constants Scripts Styles REST routes Settings Database names Templates Activation Uninstall Composer npm Built assets A plugin is not treated as complete simply because every individual file looks valid. Database & Migration Architecture The Skill determines whether plugin data belongs in: Options Site options Post metadata User metadata Term metadata Custom Post Types Taxonomies Custom database tables When custom tables are justified, it can define: Columns Types Indexes Primary keys Unique constraints Schema versions Migration strategy Uninstall behavior It also separates plugin version from database-schema version so updates can be handled safely. REST API & External Services For REST endpoints, the Skill defines: Methods Routes Request schemas Validation Sanitization Permission callbacks Ownership checks Responses Errors Caching Rate considerations For external APIs and SaaS connections it can define: Authentication Secret storage Timeout Retry logic Backoff Rate limiting Idempotency Webhooks Caching Privacy Outage behavior Testing & QA The Skill can prepare test strategies covering:

• Unit testing
• WordPress integration testing
• End-to-end workflows
• Activation
• Deactivation
• Uninstall
• Security
• Database migrations
• Compatibility
• Performance
• Admin UX
• WooCommerce workflows

It distinguishes between planned tests and tests that have actually been executed instead of falsely claiming that generated code passed validation. Security Red-Team Before serious release, the Skill can attempt to identify failures involving: Unauthenticated users Low-privilege users Capability bypass Nonce misuse Cross-user object access XSS SQL injection Path traversal Oversized uploads Duplicate webhooks Replay attacks Missing dependencies API outages Corrupted stored state Mission-critical security failures block stronger release-readiness claims. Performance Engineering The Skill audits: Database query count N+1 queries Unbounded queries Autoloaded options Remote API calls Caching Cron load Asset loading Large metadata scans Indexing Admin/public separation The goal is to prevent plugins from adding unnecessary performance overhead. Accessibility & Internationalization The Skill can evaluate: Keyboard navigation Labels Focus states Screen-reader support Contrast Form errors Dialogs Tables Translation functions Text domains JavaScript translations RTL compatibility This helps make plugins more suitable for public and commercial distribution. Free / Pro Architecture For commercial products, the Skill can design: Free-value boundaries Premium features Shared core Licensing Entitlements Update channels Downgrade behavior Migration Data compatibility The free version must remain genuinely useful, and license failures must not destroy user data. Commercial Plugin Strategy The Skill can help turn development into a sellable software product. It can prepare:

• Product positioning
• Target buyer
• Feature matrix
• Pricing model
• Free vs Pro plan
• Product-page copy
• Screenshot plan
• Demo workflow
• Documentation
• FAQ
• Support policy
• Update policy
• Release notes
• Changelog

It supports one-time sales, annual support/update models, freemium, SaaS, usage-based services, agency licenses and marketplace sales. Packaging & Release For a finished plugin product, the Skill can prepare or specify: Plugin ZIP Documentation Installation guide Quick start FAQ Troubleshooting Privacy information Changelog Release notes Product-page copy Screenshot plan Package manifest Development-only files and secrets are excluded from production packages where appropriate. Honest Release States The Skill does not label generated code as production-ready simply because code exists. It uses staged completion states including: Architecture Ready Codebase Draft Complete Generic Release Candidate Verified Release Candidate Marketplace Submission Ready The strongest states require real verification rather than assumption. Built for Real WordPress Products The objective is not: Generate some PHP snippets. The objective is: Build a coherent, secure, maintainable, testable, documented and commercially distributable WordPress plugin product.
