wp-plugin-development
by WordPressThe wp-plugin-development skill helps you build, refactor, and harden WordPress plugins with less guesswork. It covers plugin structure, hooks, activation/deactivation/uninstall, admin settings, data storage, cron jobs, and security guardrails. Use it as a wp-plugin-development guide for Backend Development tasks and existing codebases.
This skill scores 84/100 because it provides a real, install-worthy workflow for WordPress plugin development with clear triggers, concrete procedures, and supporting reference files. For directory users, that means this is a solid listing candidate: it should reduce guesswork for common plugin tasks, though it is still more guide-like than fully turnkey.
- Clear, specific trigger: plugin architecture, hooks, lifecycle, Settings API, security, and release packaging are explicitly named in the description and "When to use" section.
- Operational guidance is real and actionable: the skill includes a step-by-step procedure plus supporting references for structure, lifecycle, security, settings, data/cron, and debugging.
- Good agent leverage: the repo includes a deterministic plugin-detection script and targeted references that help an agent locate the right plugin and follow WordPress-safe patterns.
- Some workflow detail is truncated in the excerpt, so users may still need to consult the references or WordPress docs for edge cases.
- The skill has no install command and no packaged assets, so adoption depends on the host agent already being able to run the referenced scripts and work in a filesystem/bash/node environment.
Overview of wp-plugin-development skill
wp-plugin-development is a WordPress-focused skill for building, refactoring, and hardening plugins with less guesswork than a generic prompt. It is best for people working on plugin architecture, hooks, activation/deactivation/uninstall behavior, admin settings, data storage, cron jobs, and security-sensitive code paths.
What this skill is for
Use the wp-plugin-development skill when the task is not just “write some PHP,” but “make this plugin work correctly inside WordPress.” It helps with the decisions that usually block progress: where the bootstrap file should live, how hooks should be registered, how settings should be saved safely, and what to do during lifecycle events.
Best-fit users and projects
This skill fits backend development work on standalone plugins, plugin modules inside a larger WordPress repo, and maintenance tasks in existing codebases. It is especially useful when you need a wp-plugin-development guide that respects WordPress conventions instead of inventing a custom framework around them.
What makes it different
The main value is the workflow discipline: it points you to plugin entrypoints, lifecycle rules, security guardrails, and supporting reference files before you change code. That makes wp-plugin-development more practical than a one-off prompt because it is designed for install, inspection, and implementation in the right order.
How to Use wp-plugin-development skill
Install and confirm the plugin target
Use the wp-plugin-development install command in the repository context you are editing:
npx skills add WordPress/agent-skills --skill wp-plugin-development
After install, confirm which plugin you are touching. In a full site repo, identify the correct plugin under wp-content/plugins/ or mu-plugins/ before you edit anything. This is one of the most common failure points.
Feed the skill the right starting facts
The skill works best when you provide: the repo root, the plugin path or main file if known, the WordPress/PHP versions, and whether the site is single-site or multisite. If your goal depends on WP-CLI or release packaging, say that up front. These details affect API choices, compatibility, and whether a suggested fix is safe to apply.
Use a prompt that names the job clearly
Strong input is specific, not broad. For example:
- “Refactor the plugin bootstrap so admin-only hooks are loaded lazily.”
- “Add a settings page with sanitization, capabilities, and saved defaults.”
- “Fix the activation routine so rewrite rules are flushed only after registration.”
- “Audit this plugin for nonce, escaping, and SQL safety issues.”
Those prompts help the wp-plugin-development skill choose the right path instead of guessing whether you want structure, lifecycle, settings, or security work.
Read these files first
Start with SKILL.md, then check references/structure.md, references/lifecycle.md, references/settings-api.md, references/security.md, references/data-and-cron.md, and references/debugging.md. If the repo includes it, run scripts/detect_plugins.mjs to find plugin headers quickly. That order gives you the fastest path from install to useful output.
wp-plugin-development skill FAQ
Is wp-plugin-development only for new plugins?
No. It is just as useful for refactors, bug fixes, and cleanup in existing plugins. In practice, many wp-plugin-development usage cases are about correcting hook timing, lifecycle behavior, or security mistakes in code that already exists.
When should I not use this skill?
Do not use it if you are not changing WordPress plugin code. It is a poor fit for generic PHP libraries, theme-only work, or UI copy changes that do not touch plugin behavior. If your task is outside backend development for WordPress plugins, the advice will be too specific.
Is this better than a normal prompt?
Yes, when the task needs WordPress-specific decisions. A normal prompt may produce working PHP, but the wp-plugin-development skill adds guardrails around bootstrap structure, activation hooks, Settings API usage, and sanitization/escaping so the result is more deployable.
Is it beginner-friendly?
Yes, if you can describe the plugin goal and the file you want changed. Beginners usually benefit most from the skill’s file-reading path and its focus on “what to check first” before editing code.
How to Improve wp-plugin-development skill
Give the skill the real constraint, not just the feature
The fastest way to improve results is to include the constraint that matters most: compatibility version, multisite behavior, whether the plugin is already published, or whether you need a minimal patch versus a cleanup refactor. That helps the wp-plugin-development skill avoid recommending changes that are correct in theory but wrong for your release.
Show the current shape of the plugin
If you want better code changes, share the main plugin file, relevant class names, and the current hook flow. For example, “bootstrap is in my-plugin.php, admin code loads unconditionally, and settings are stored in one option array.” That gives the skill enough context to propose a structure that matches the existing repo instead of inventing a new one.
Ask for the output you can actually apply
Good requests tell the skill what you want back: a patch plan, a file-by-file edit strategy, a security review, or a release checklist. If you need a wp-plugin-development guide for a specific outcome, say whether you want “safe minimal changes” or “a cleaner architecture with breaking-change awareness.”
Iterate from symptoms to fixes
If the first answer is too broad, narrow it to the failure mode: “activation hook not firing,” “settings not saving,” “cron runs twice,” or “nonce check passes but authorization is missing.” The most useful improvement loop is symptom → relevant reference file → code change → recheck. That keeps the skill focused on the part of the plugin that actually blocks adoption.
