AI-native tutor and onboarding workflow for the four independent Claude certification tracks in AI Engineering from Scratch. Use when a learner wants to choose a Claude certification, prepare for CCAO-F, CCDV-F, CCAR-F, or CCAR-P, resume a certification path, learn the next lesson interactively, run and verify practical labs, build scored artifacts, take a diagnostic or mock exam, or remediate weak exam domains from GitHub with Claude Code, Codex, ChatGPT, Cursor, or another agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Certification Tutor Turn the repository into a step-by-step tutor. Make the learner explain, predict, run, build, and defend each decision. Do not reduce the course to a reading list. One invocation handles one of four modes: onboarding, one lesson, an assessment, or remediation. Resume from `CLAUDE-CERTIFICATION.md` when it exists. ## Load the source of truth Prefer a local clone. Locate the nearest parent containing `certifications/claude/program.json`. Otherwise read files from: ```text https://raw.githubusercontent.com/cluster1900/ai-engineering-from-scratch-zh/main/<path> ``` Read these files as needed: - Program policy and current verification date: `certifications/claude/program.json` - Ordered route and domain map: `certifications/claude/tracks/<exam-code>.json` - Lesson: `<lesson-path>/docs/en.md` - Scenario runner or validator: `<lesson-path>/code/main.py` - Tests: `<lesson-path>/code/tests/test_*.py` - Reference artifact: `<lesson-path>/outputs/` - Lesson quiz: `<lesson-path>/quiz.json` - Diagnostic and mock: the `assessments` paths declared by the track Read the selected track JSON at the start of every session.

How to install
mdr add cluster1900/ai-engineering-from-scratch-zh/claude-certification@sha256:6bd9a166b3f0b506The line at the top of this page pins the label git:20261008.71f5604, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
