A Claude Code and Codex Skill for Deliberate Skill Development

· ai devtools coding · Source ↗

TLDR

  • Claude Code / Codex plugin that interrupts agentic coding sessions with 10-15 minute evidence-based learning exercises tied to your own project work.

Key Takeaways

  • Installs as a Claude Code plugin (/plugin marketplace add) or Codex plugin (codex plugin marketplace add) from a GitHub-hosted marketplace.
  • Triggers after significant work events: new files, schema changes, refactors, or any session where you asked “why” questions.
  • Exercise types include prediction-observation-reflection, generation-comparison, teach-it-back, and retrieval check-ins; Claude pauses and waits for your input rather than answering its own questions.
  • Grounded in cognitive science: targets generation effect, fluency illusion, spacing effect, and retrieval practice to counter habits formed by fast agentic workflows.
  • Companion skills: learning-opportunities-auto (post-commit hook), orient (repo orientation lessons), and Learning-Goal (MCII-based goal-setting).

Hacker News Comment Review

  • Early commenters are curious but want a concrete interaction transcript before committing to setup; absence of a worked example is the main friction point noted.
  • Interest skews toward self-directed language learning use cases (e.g., Java Spring) rather than pure productivity tooling, suggesting the skill may resonate beyond its intended agentic-coding context.
