What problem this solves

Users forget information provided by chatbots; difficulty in retaining knowledge from explanations; inefficient onboarding to new codebases; lack of active recall and spaced repetition in AI tutoring.

Summary

A Claude Code plugin/skill, drill-me, that transforms Claude into a spaced repetition tutor. It leverages cognitive science principles like retrieval practice, spaced repetition (simplified FSRS), optimal difficulty, and confidence ratings to help users actively learn and retain information, including complex codebases, by quizzing them before explaining.

Why it is useful

This workflow provides a concrete, scientifically-backed solution to a common problem: retaining information learned from AI interactions and efficiently onboarding to new codebases. It leverages Claude Code's capabilities to create an active learning environment, moving beyond passive explanation to proven methods of long-term memory formation. Its applicability to codebases makes it particularly valuable for developers.

Workflow

1. Install drill-me via Claude Code plugin marketplace: /plugin marketplace add timini/drill-me followed by /plugin install drill@drill-me.
2. Alternatively, install as a standalone skill using npx: npx skills add timini/drill-me.
3. Initiate a drilling session on a general topic: /drill:me rust lifetimes.
4. Initiate a drilling session on a specific codebase or flow: /drill:me this repo's auth flow.
5. Engage with Claude by answering questions, which constitute the majority of the session.
6. Rate your confidence in your answer before revealing Claude's explanation.
7. Revisit concepts as scheduled by the spaced repetition algorithm, focusing on items you are about to forget.

Tools / artifacts

• drill-me plugin/skill
• Claude Code environment (or Amp/Codex/Cline)
• npx (Node Package eXecutor)
• ~/.drill-me/ directory (for learning ledger)
• Markdown files (for learning cards and stability/due dates)
• GitHub repository (timini/drill-me)

Validation signals

• Citations to cognitive science studies (e.g., retrieval practice, FSRS, Wilson et al., Nature Comms 2019).
• Empirical claims based on research (e.g., "Retrieval practice beats re-reading across 217 studies").
• Personal validation from the author: "Best onboarding tool I've accidentally built."
• Open-source nature (MIT license) with no telemetry, allowing for inspection and trust.

Cautions

• The tool is open source (MIT license), has no telemetry, and stores learning data in plain, user-readable/editable markdown files, ensuring transparency and user control over their data.

Limitations

• As a new tool, it lacks extensive community validation and long-term usage reports.
• Effectiveness relies on the user's consistent engagement with the spaced repetition system.
• The depth of learning might be more suited for factual recall and conceptual understanding rather than complex problem-solving skills, though codebase drilling is a strong use case.
