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 verify-rubric             # check the review rubric's structure
gov recall <terms>            # retrieve notes, decisions, postmortems
gov audit-notes               # staleness signals in implemented notes
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, the notes README, and the agent skills (recall-first, pre-push-checks, code-review, archive-agent-notes) only when missing, appends one reference line to AGENTS.md, and never overwrites the project's own files — including its own skills. 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 over gates.json), verify_notes (three required sections), verify_translation_pairing (git blob hashes), verify_note_presence, verify_rubric, recall (memory retrieval), audit_notes (staleness signals), change_scope, self_test, archive_notes.
gov/templates/ — the rules, default gates.json, notes format, and agent skills that gov init injects into a project.
.gov/rules.md — the single source of truth for the rules.
.agents/notes/ — the decision-record format and lifecycle.
.agents/skills/ — the triggers that send agents to the tools first: recall-first (memory before proposals), pre-push-checks (smallest sufficient set), code-review (rubric), archive-agent-notes.
docs/review-rubric.md — how PRs are judged: the criteria gates cannot check, graded item by item.

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.
