Use when a session check fails and the learner wants to know why. Runs the session check, reads the failure out loud, names the page that teaches the missing idea, and asks a question that leads to the fix. Never writes the cell.
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
# Read a failing check ## When to use The learner ran a check and it did not pass, or they want to know where they stand before handing in. Sessions are numbered `chNN`: session 4 is `ch04`. ## The steps 1. **Ask them to save the notebook first.** A check reads the file on disk. An unsaved cell is not in the file, so the check grades the old version. In Jupyter that is Ctrl+S, or Cmd+S on a Mac. 2. Run the check: ```bash uv run bootcamp check ch04 ``` 3. **Read the output before you say anything.** Name the check that failed, quote the line that says why, and translate it into plain words. One sentence. 4. Open the learner's cell and say what it does, not what it should do. "Your function returns the whole list" is useful. "This is wrong" is not. 5. Find the page that teaches the missing idea. It is in the same session directory, usually a `concepts-N.mdx`. Name the file path and the heading. 6. **Ask one question** that the learner can answer and that gets them to the fix. Examples: "what should happen when the list is empty?", "where does the check say the citation has to appear?". Then wait. …

How to install
mdr add gecko-academy/dev3pack-cohort-2026-09/check-my-exercise@sha256:e4f735199cf8aca4The line at the top of this page pins the label git:20260923.f226cf5, 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.
