How to Add a Quality Gate to Your AI Agent in 2 Minutes

A quality gate is useful when it turns an agreed engineering standard into a repeatable check. It is harmful when a team copies an arbitrary threshold, receives a wall of legacy findings, and disables the job on day one.

This quick setup uses aislop as one deterministic layer. It catches named code-hygiene patterns and returns a CI exit code. It does not prove that the feature works or that the design is safe.

1. Establish the baseline

npx --yes aislop@0.13.1 scan

Read the findings before adding enforcement. Confirm that high-severity results are real, note rules that need configuration, and record the current score. This is the floor you will improve from—not a grade to compare with unrelated repositories.

2. Add a reproducible GitHub Actions job

Create .github/workflows/aislop.yml:

name: aislop

on:
pull_request:

jobs:
quality-gate:
  runs-on: ubuntu-latest
  steps:
    - uses: actions/checkout@11d5960a326750d5838078e36cf38b85af677262 # v4
    - uses: actions/setup-node@49933ea5288caeca8642d1e84afbd3f7d6820020 # v4
      with:
        node-version: 24
    - run: npx --yes aislop@0.13.1 ci

The full SHAs make the executed actions immutable; the comments preserve the readable major versions. The exact package version pins the CLI. These values were current when this article was updated, so review release notes and update the pins deliberately.

3. Introduce the threshold carefully

Initialize the repository configuration or create .aislop/config.yml, then set the CI floor using the key documented by the current CLI:

ci:
failBelow: 70

Replace 70 with a value justified by the baseline. If the repository scores 58, a threshold of 80 creates a cleanup project, not a useful PR gate. Start near 58, fix high-impact findings, then raise the floor.

Leave the workflow non-required for several representative pull requests. Once the team has reviewed the signal, make the job a required status check in the repository's branch rules.

4. Give the agent feedback before the PR

For Claude Code, aislop can install a quality-gate hook:

npx --yes aislop@0.13.1 hook install --claude --quality-gate

Review the generated hook before sharing it across a team. Local feedback is faster than waiting for CI, but CI remains the authoritative shared check because local hooks can be skipped or misconfigured.

What this gate can and cannot do

It can: enforce configured repeatable rules, surface findings before human review, provide structured feedback, and fail CI below the agreed floor.

It cannot: prove correctness, validate a threat model, decide whether the feature solves the right problem, or replace tests and review. Keep those controls in the workflow.
