Plant subtle multi-file bugs in a HOL lab app. Bugs span 2-3 files, are diagnosable from symptoms, have a clear 'aha' moment, and can be caught by a test.

Build a complete HOL lab repo from a brief. Reads a PDF/doc/text brief describing the company and app concept, asks clarifying questions, then generates a fully working Python/FastAPI/SQLite app with planted bugs, seed data, and feature exercises.

Propose 3-5 feature ideas for a HOL spec-driven build exercise. Features touch multiple layers, are buildable in ~30 min with Claude Code, and are visually demo-able.

Validate a HOL lab by simulating a participant. Walks through all 5 Acts (Explore, Fix, Spec, Build, Show & Tell) and produces a validation report with pass/fail, timing, and facilitator recommendations.

Rebrand a lab app to match a company profile. Updates app name, domain language, API paths, seed data names, and UI copy to feel authentic to the target company and industry.

Generate realistic synthetic seed data for a HOL lab app. Reads the app's models and creates 20-50 records per entity with industry-authentic values, realistic relationships, and useful edge cases.
