# bar-raiser — Bar-Raiser is a cutting-edge framework designed to help engineering teams tackle technical debt, streamline development workflows, and elevate code quality.

License: permissive · Maintenance: active · Downloads: 101.9K/mo

## What it is and what it does

Bar-Raiser is a framework that bridges code quality tools and GitHub pull requests by creating check runs with inline annotations, autofix actions, and Slack notifications. It integrates with Ruff (linting/formatting), Pytest (test results), and Pyright (type checking), parsing their outputs and surfacing issues as GitHub annotations rather than forcing developers to read console logs. The package depends on pygithub for GitHub API access, gitpython for repository operations, cryptography for signing, and slackclient for notifications, plus AWS libraries (aioboto3, boto3) suggesting cloud-native deployment patterns.

The framework targets engineering teams managing technical debt at scale. It supports autofix actions (applying fixes with a single click) and Slack notifications mapped from GitHub logins, though autofix requires a separate webhook service to receive and apply changes. The package is actively maintained, supports Python 3.11 and later, and carries no known vulnerabilities. It is early-stage (first release 2024-12-16) with a permissive BSD-3-Clause license.

Use it for:

- Embed Ruff linting results as inline annotations on pull requests with one-click autofix actions for formatting and style issues
- Surface Pytest test failures as GitHub check annotations linked to specific lines of code, reducing time to debug test failures
- Run Pyright type checks and display type errors as PR annotations with autofix suggestions for common type issues
- Send Slack notifications to developers when checks fail, mapped by GitHub login to Slack user ID for targeted alerts
- Consolidate multiple code quality tool results into a single GitHub check run instead of separate CI job outputs

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Bar-Raiser creates GitHub checks with inline annotations, autofix actions, and Slack notifications for code quality tools like Ruff, Pytest, and Pyright, integrating linting and test results directly into pull requests.

Yes, if you run Ruff, Pytest, or Pyright in CI and want their results surfaced as GitHub PR annotations with Slack notifications. The low install friction, active maintenance, and permissive license make it a low-risk addition. The nine runtime dependencies are standard packages. Early-stage API stability (Python API may change) is the main caveat—pin the version and monitor releases if you depend on it heavily. No known vulnerabilities.

## Install

pip install bar-raiser
uv add bar-raiser
poetry add bar-raiser

## Installing bar-raiser

Before you install: Low install friction with a pure-Python wheel. Active maintenance with a recent release 57 days ago and commits through July 2026. Nine runtime dependencies including pygithub, gitpython, and AWS libraries add some complexity but are all standard packages.

License in practice: BSD-3-Clause is permissive and poses no restrictions on commercial or private use. You can use, modify, and distribute this package with minimal legal friction.

Quickstart:

pip install bar-raiser

from bar_raiser.checks.annotate_ruff import AnnotateRuff

# Requires GitHub app credentials (APP_ID, PRIVATE_KEY) and pull request context
checker = AnnotateRuff(app_id=..., private_key=..., pull_number=...)

Requires Python 3.11 or later. GitHub app credentials (APP_ID, PRIVATE_KEY) and environment context (PULL_NUMBER) are needed to create checks. Optional Slack integration requires SLACK_BOT_TOKEN and a GitHub-to-Slack user ID mapping file.

Verify before relying:

- Whether the autofix webhook service setup is documented or provided as part of the package
- Performance characteristics when handling large numbers of annotations or multiple check types in parallel
- Compatibility with GitHub Enterprise or other GitHub API variants beyond public GitHub
- Maximum Python version supported (requires_python specifies <3.14 but upper bound behavior unclear)
