Use when a user wants to create, edit, organize, schedule or study flashcards in Etude (a spaced-repetition app with programmable card types and AI grading), quiz them in chat from their decks, check their progress, or author packs and card types. Drives everything through the `etude` CLI, which prints JSON.
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
# Etude
Etude is a spaced-repetition app, like Anki, with card types written in HTML/CSS/JS, scripted or AI grading, and an FSRS scheduler. Everything the web app does is a command: `etude <group> <verb> [args] [flags]`. Output is JSON on stdout; errors are `{"error","code"}` on stderr with a non-zero exit.
## Find the CLI and the database
```sh
etude version || node ~/path/to/etude/src/cli/main.ts version # from a checkout; Node 24+ runs .ts directly
etude db path # which database, and why (--db, $ETUDE_DB, $ETUDE_HOME/etude.db, ~/.etude/etude.db)
etude commands # machine-readable catalog of every command, flag and output shape
etude <group> --help # verbs in a group; `etude <group> <verb> --help` for flags and examples
```
The CLI opens the SQLite database directly. The server doesn't need to run, and it's safe to use while it does. If the user has more than one collection, ask which one, then pass `--db PATH` on every call. For experiments, use a scratch home: `ETUDE_HOME=$(mktemp -d) etude ...`.
Read `docs/cli.md` in the repo for the full reference and recipes. Don't guess flags: check `--help` first.
## Mental model
…Read the whole file at its exact version.
How to install
mdr add zibhelina/etude/etude@sha256:98ce4827a4ca9886The line at the top of this page pins the label git:20261030.687a559, 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.
