Plugin
A plugin is an optional software component that extends or modifies a host application’s capabilities through an extension or integration mechanism.
WordPress Power Toolkit: Harness AI to build next-level websites
A WordPress plugin is an installable software extension that adds or modifies functionality in a WordPress installation.
- How it is used
- Adds site capabilities such as security, forms, menus, search optimization, and media features without requiring code.
- How deep it goes
- Defines plugins, gives selection and conflict-isolation procedures, and demonstrates packaging AI-generated PHP as an uploadable plugin.
- Examples
- Uses Wordfence, UpdraftPlus, AIOSEO, mega-menu tools, and a GMT date-and-time sidebar widget.
- What you can do after
- Operate/configure plugins by selecting, installing, activating, maintaining, and isolating conflicting extensions.

Logs and Telemetry
A plugin is an independently implemented software component that extends an application's capabilities through a defined integration interface.
- How it is used
- Composes Fluent Bit event pipelines from input, filter, and output building blocks.
- How deep it goes
- Defines plugin roles and interfaces, then defers extension-language trade-offs to later treatment.
- Examples
- Uses dummy input help, stdout output selection, CLI pipeline controls, and Go input/output plugin code structure.
- What you can do after
- Operate/configure plugins through Fluent Bit CLI controls and assess external-extension deployment requirements.
Build an AI Agent (From Scratch)
An agent skill is a reusable capability that packages knowledge or procedures for carrying out a class of tasks.
- How it is used
- Organizes agent capabilities without placing every detailed tool instruction in every prompt.
- How deep it goes
- Works through folder layout, three disclosure levels, Python discovery, prompt generation, sandbox upload, and a PDF-merge execution flow.
- Examples
- Uses a PDF-merge SKILL.md with pypdf and traces selection, documentation reading, code execution, and output confirmation.
- What you can do after
- Build it from scratch by loading skill metadata, listing summaries in the prompt, and making skill folders available in a sandbox.
AI Agents in Action
A plugin is a registered capability consisting of functions that a Semantic Kernel can expose for use in conversations or interactions.
- How it is used
- Extends agents and chat interfaces with well-defined actions such as API calls, web searches, recommendations, and data retrieval.
- How deep it goes
- Explains plugin types, folder structure, registration, invocation, and chat exposure, while deferring complete production testing.
- Examples
- Uses movie recommendations, TMDb movie searches, temperature conversion, weather retrieval, creative writing, meal planning, and news APIs.
- What you can do after
- Build and operate plugins that expose semantic prompts or native code to Semantic Kernel agents and chat sessions.
LLMs in Production
OpenAI Plugins are extensions that let ChatGPT access third-party tools and external APIs.
- How it is used
- Connects ChatGPT with third-party tools and external APIs.
- How deep it goes
- Explains configuration, hosting, registration, review, and operational limitations without detailing API implementation.
- Examples
- Uses weather lookup, web search, OpenAPI configuration, and ai-plugin.json as concrete integration examples.
- What you can do after
- Build it from scratch by describing an API, defining plugin metadata, hosting files, and submitting the integration for review.
Terraform in Depth: Infrastructure as Code with Terraform and OpenTofu
A plugin is a software component that extends a host application's capabilities through a defined extension interface.
- How it is used
- Extends TFLint with generic, provider-specific, or custom policy rules for Terraform static analysis.
- How deep it goes
- Configures enablement, presets, versions, sources, exclusions, and inline exceptions, while custom plugin development requires Go.
- Examples
- Demonstrates Terraform, AWS, Azure, and Google plugins alongside Make targets, diagnostics, disabled rules, and inline ignores.
- What you can do after
- Operate/configure TFLint plugins to initialize rule sets, customize checks, and handle justified exceptions.
