Set up the Fallow app in Codex after the plugin is installed: check the fallow installation, choose the default analysis scope, run the first analysis, and show the user where the dashboard, the Code Health tab, @Fallow mentions and the config editor are. Use when the user chooses Set up for Fallow in Codex, or asks to onboard or configure the Fallow app. Do not use for setting up lint, format or CI tooling; use fallow-setup for that.
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
# Set up Fallow in Codex
Use the Fallow app tools. Keep each step short. Ask one question at a time.
## 1. Check the installation
Call `fallow_check_install` with `{}`.
- If it reports a version, continue.
- If fallow is missing, explain that the app runs the fallow CLI locally and
that no code leaves the machine. Offer to install it globally with
`npm install --global fallow`. The sidebar dashboard needs a fallow on PATH,
because the app runs a copy inside the project only within the Codex sandbox
of a thread. Run the install only after the user agrees. Then call
`fallow_check_install` again.
## 2. Choose the defaults
Call `fallow_settings_read` with `{}`. Ask these questions, one at a time.
Skip a question when the user already answered it.
1. "Analyze the whole project by default, or only the files your branch
changed?" Map the whole project to `scope: "full"` and changed files to
`scope: "changed"`.
2. "Leave tests, stories and dev tooling out of the analysis?" Map yes to
`production: true`.
Call `fallow_settings_update` with a `set` object that holds only the changed
values, for example `{"set":{"scope":"changed"}}`. Skip the call when nothing
…Read the whole file at its exact version.
How to install
mdr add fallow-rs/fallow-skills/fallow-codex-onboarding@sha256:844f5bb9edcee397The line at the top of this page pins the label git:20261009.723d969, 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.
