govrail
English | 中文
A language-agnostic governance plane for agent-driven development: coding agents work fast in parallel while machines — not vigilance — hold the quality line. The only runtime dependency is Python 3.
The plane ships two mechanisms: gates (any promise a command can check becomes a mechanical check) and notes (every non-trivial change records the decision, what it beat, and the consequences). Bilingual pairing keeps the external-presentation docs in sync.
What it changes
| Without govrail | With govrail |
|---|---|
| Agents follow rules "on their honor"; nothing is enforced | Every checkable promise is a gate that fails loud |
| "Why did we do this?" is lost or re-litigated | Each decision is a note with the alternatives it beat |
| Adopting tooling means a restructure or a new runtime | One command, zero restructure: gov init |
See a governed project in examples/demo-project.
Install
pip install govrail # or: uv tool install govrail / pipx install govrail
This puts the gov CLI on your PATH (stdlib only — no third-party
dependencies). It has one subcommand per action:
gov init --project <path> # inject the plane into an existing project
gov init --project <path> --hooks --ci # also install a pre-push hook and CI
gov uninstall --project <path> # reverse it exactly
gov run # run the default mode's gate DAG (defaultMode)
gov run --base HEAD~1 # only the gates whose paths match the diff
gov run --gate pairing # rerun a single gate
gov self-test # prove every governance gate can reject
gov verify-pairing --write # re-confirm a bilingual pair after editing one side
gov verify-pairing --write en:docs/a.md zh:docs/a_CN.md # register any naming
gov verify-note-presence # warn when a non-trivial diff carries no Agent Note
gov change-scope --base <ref> # smallest sufficient check set for a diff
init is non-invasive and idempotent: it creates .gov/rules.md, adds
gates.json and the notes README only when missing, appends one reference line
to AGENTS.md, and never overwrites the project's own files. uninstall reverses
it exactly — including the hook and workflow --hooks/--ci added. A fresh
install never goes red on its first run: the pairing gate ships advisory,
gov verify-pairing --write baselines the existing pairs, and removing
allowFailure turns it enforcing. enabled: false parks a gate without
deleting its definition.
What is inside
gov/— the Python package:gates(the DAG runner overgates.json),verify_notes(three required sections),verify_translation_pairing(git blob hashes),change_scope,self_test,archive_notes.gov/templates/— the rules, defaultgates.json, and notes format thatgov initinjects into a project..gov/rules.md— the single source of truth for the rules..agents/notes/— the decision-record format and lifecycle.
Origin
The mechanisms are distilled from the DeepSeek Harness repository, whose gates-over-prose axiom shaped this template. Kept: the governance plane. Left to you: the product plane. The locked design decisions live in docs/decisions.md.
