Wp Plugin Development

Implement WordPress plugins with explicit lifecycle behavior, permissions and maintainable integration points.

Editorial review checked 2026-10-29 against this instruction snapshot. Supporting scripts and runtime behavior remain outside this editorial review.

What it does

The workflow covers plugin discovery, architecture, hooks, settings, storage, scheduled work and release concerns. It emphasizes nonce checks, capabilities, sanitization and output escaping as separate responsibilities. This provides a useful implementation checklist when a small feature touches several WordPress interfaces and lifecycle stages.

Best for

Developers creating plugins or extending existing plugin behavior without replacing the project architecture.

Tradeoffs and requirements

Activation, uninstall and migration code can affect persistent user data. A nonce is not an authorization decision, and a successful administrator workflow does not demonstrate that lower-privilege or anonymous users are correctly restricted.

Targets WordPress 7.0+ (PHP 7.4.0+). Filesystem-based agent with bash + node. Some workflows require WP-CLI.

Install from the source

Inspect the pinned source snapshot and its supporting files first. The command selects this skill through the open-source skills CLI. Node.js and agent-specific setup may be required. Installation can download code. Catalog ingestion never executes skill instructions or install scripts.

After source review, use npx skills check and npx skills update to inspect and apply upstream updates. Re-check changed instructions before running them.

Safety & review signals

Static review only. This is not a security audit or a guarantee of safety.

SKILL.md text only; scripts, dependencies and runtime behavior not audited.

No configured text patterns matched. Unmatched or concealed behavior can still exist.

Allowed tools declaration: Unknown. Runtime permissions and network behavior: Unknown.

Offline package integrity

A temporary folder-copy check, not an agent installation or runtime safety verdict.

8 files copied and checksummed from this exact source snapshot. No package code or installation scripts were executed.

Isolated helper checks

Selected helper behavior only. Full agent compatibility and runtime safety remain unverified.

3 synthetic scenarios passed for skills/wp-plugin-development/scripts/detect_plugins.mjs, checked 2026-10-29. The container had no network, production data or credentials, and only read-only fixture and helper mounts.

Supporting-file static inspection

Bounded source inspection, not a runtime security audit. This inspection does not execute code.

1 text files inspected at this exact repository snapshot. 6 files outside the inspection budget or type allowlist. Dependencies were not installed or independently audited.

    Absence of a pattern is not proof of safety. Permission needs and runtime behavior remain Unknown.

    Inspected file inventory

    Suggested workflow

    Locate the real plugin entrypoint and existing service boundaries. Implement the smallest feature, reuse established hooks and storage conventions, and specify what activation, deactivation and uninstall should each do before introducing irreversible cleanup behavior.

    How to judge the result

    Test the feature with appropriate and insufficient capabilities, malformed inputs and repeated requests. Exercise installation and upgrades in a disposable site, inspect scheduled work and verify that removing the plugin preserves or deletes data only according to its documented policy.
