Run the Muggle onboarding walkthrough in the agent: saves first-time preferences and offers the CI check. Use on muggle init. To change one saved setting, use muggle-preferences.
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
# Muggle Init
> Telemetry first step: see [`_shared/telemetry-emit.md`](../_shared/telemetry-emit.md). Use `skillName: "muggle-init"`.
> Running outside Claude Code (in Codex, for one)? Read [`../_shared/host-tool-equivalents.md`](../_shared/host-tool-equivalents.md) first — it maps the tools and paths this skill names to your host's.
`muggle init` prompts in a terminal, which an agent cannot answer. This skill renders the same walkthrough with `--json` and saves the answers with `--apply`.
## Steps
1. Run `muggle init --json` and show `primerHeadline` and `primerBullets`.
2. Ask for the blanket choice with `AskUserQuestion`, one option per `blanketOptions` entry, using its `label` and `description`.
3. On `customize`, ask each group in order:
- `toggle` — multi-select of its `entries`, pre-selecting `isSelectedByDefault`. Collect the selected keys into `selectedToggleKeys`.
- `choice` — single-select of its `options`, the `isDefault` one first. Record `choices[<key>] = <value>`.
4. Write the answers to a temp file: `{ "blanket": "<choice>", "selectedToggleKeys": [...], "choices": { ... } }`. The last two fields only apply to `customize`.

How to install
mdr add multiplex-ai/muggle-ai-works/muggle-init@sha256:472eece63291fb99The line at the top of this page pins the label git:20261105.5c63447, 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.
