Moodle Plugin Development AI Agent Skill

What changed

The moodle-plugin-development repository introduces an AI coding agent skill designed to guide the creation of Moodle plugins through a structured, spec-driven workflow. This approach contrasts with directly generating code from an initial idea, aiming to enhance the reliability of AI-assisted development. The skill is implemented as a single markdown instruction file, making it compatible with various AI coding agents, including Claude Code as a native skill or by pasting its content into the system prompts of other agents like Cursor or Copilot.

The workflow is divided into six distinct phases:

• Problem & Context: An interview-style process to define the core problem, user impact, success metrics, and constraints, documented in intent.md.
• Design: Detailed requirements gathering, user stories, and test scenarios (Given/When/Then) for different roles, along with optional visual and privacy-by-design considerations, captured in specs.md and user-stories.md.
• Approval Gate 1: A formal sign-off on the clean specification before any coding begins.
• Build: Development of a technical implementation plan (plan.md, tasks.md), followed by implementation where each test scenario becomes an automated test, with initial self-testing by the developer.
• Independent Test Phase: Code review, functional testing by a separate individual, and acceptance testing by stakeholders, leading to final approval.
• Release: Deployment, documentation updates, and a post-release monitoring period for regressions.

The repository also includes installation instructions for Claude Code and other AI agents, along with related projects like moodle-plugin-scaffold for project setup and moodle-plugin-vibe-review for code review.

Why it matters for builders

This AI skill provides Moodle developers with a framework to leverage AI more effectively and reliably. By enforcing a spec-driven process, it helps mitigate the risks associated with "vibe coding" or generating code without clear requirements and validation. Developers can use this skill to ensure that AI-generated plugins are built on a solid foundation of agreed-upon specifications and comprehensive testing, leading to more robust and predictable outcomes.

Practical impact

Developers can integrate this skill into their AI coding workflows by cloning the repository and either using it as a Claude Code skill or by incorporating its markdown instructions into their preferred AI agent's configuration. The structured approach encourages thorough upfront planning and testing, which can lead to reduced debugging time and higher quality plugin releases. For those using related tools, this skill is designed to feed directly into projects like moodle-plugin-scaffold.

Caveats and source limits

The provided source is a GitHub repository description and does not include independent benchmark results or specific performance metrics for the AI skill. The effectiveness of the workflow is contingent on the quality of the input specifications and the capabilities of the AI agent used. The source also mentions related tools but does not detail their integration beyond conceptual alignment. The project is licensed under MIT.
