grai-gate

Deterministic anti-slop gate for markdown written by coding agents. One Python engine, no model calls, no network. It scores sentence burstiness and flags the structural habits that survive spellcheck.

GitHub Action

name: cadence
on:
  pull_request:
    paths: ['**.md', '**.mdx', '**.txt']
jobs:
  gate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: adrianpeticila/grai-gate-action@v0.1.3
        with:
          fail-on-slop: "false"

The action scores only files changed in the pull request. It fetches the base ref itself, so a shallow checkout is fine. The default is advisory: the card lands in the log and the job stays green. Set fail-on-slop: "true" to block.

Inputs: path (scan target when no pull request base is available), fail-on-slop, verbose.

PyPI

pipx run grai-gate README.md

or

pip install grai-gate
grai-gate docs/

Exit codes: 0 clean, 1 slop, 2 input error. The CLI accepts -h and --help.

pre-commit

repos:
  - repo: https://github.com/adrianpeticila/grai-gate-action
    rev: v0.1.3
    hooks:
      - id: grai-gate

The hook scores markdown, mdx, and plain text. It exits 1 on slop and stops the commit. Skip one commit with SKIP=grai-gate git commit.

One engine

src/grai_gate/gate.py is vendored byte-for-byte from the Antigravity plugin in the grai repo. Run python scripts/sync_engine.py --check to prove the copies match; it exits 1 on drift.
