Set up, evaluate or turn off the optional Open Second Brain decision-model feature (typed judgments that rerank search, pick skills, pre-filter extract-signals turns, filter recalled notes and annotate dedup, tension, label and answerable proposals). INVOKE when the user mentions decision models, Jev, TypeSafe, OpenRouter or Vercel decisions, the `decision_model_*` config keys, or after `o2b decision-model check` reports an error, a warning or a hint. SKIP when the user only asks conceptual…
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
# Decision-model setup
A decision model answers typed questions (yes/no probability, one of a
list, a position on a scale) about text Open Second Brain hands it, and
never generates text. Open Second Brain uses it only to choose among
candidates its own code produced: which search results come first, which
skills to offer, which transcript turns the host should mine, which
recalled notes to inject, and advisory verdicts next to dedup, tension,
label and answerable proposals. It never writes to the vault.
The feature is off by default. Without it Open Second Brain behaves
exactly as it does today and makes no network call. Full reference:
`docs/decision-models.md` (the hub, with the per-use table) and
`docs/decision-models/providers.md` (every route).
For a conceptual question ("what is Jev", "is this worth it", "which
route is cheaper") answer from the docs and change nothing. Walk the
steps below only when the user wants to set it up, measure it or turn it
off.
## Step 1: always start with `check`
```bash
o2b decision-model check
```
It prints the status (`disabled`, `no_key`, `disabled_by_vault`,
`invalid`, `active`), the provider and processor, the key variable's

How to install
mdr add itechmeat/open-second-brain/decision-model-setup@sha256:d8f2153d61126bd1The line at the top of this page pins the label git:20261017.f6d9f95, 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.
