gh-observer

A GitHub PR check watcher that improves on gh pr checks --watch by showing runtime metrics, queue latency, and better handling of startup delays.

Why?

The existing gh pr checks --watch doesn't show how long checks have been running, doesn't handle the 30-90s startup delay well, and doesn't show queue latency. This creates anxiety when watching CI runs - "is it stuck or just slow?"

Features

• ⏱️ Runtime metrics - Shows elapsed time: 3m 52s tells you exactly how long checks have been running
• ⏳ Queue latency - Displays wait time: 15s shows how long GitHub queued the job before starting
• 🔄 Real-time updates - Auto-refreshes every 5s (configurable) without manual polling
• ⚡ Startup phases - Helpful messages like "Waiting for Actions to start..." during the 30-90s GitHub delay
• 🛡️ Rate limits - Backs off automatically when approaching API limits to avoid interruptions
• ✅ CI-friendly - Returns exit codes (0=success, 1=failure) for script automation

Installation

Install precompiled binary

The easiest way to install gh-observer is as a GitHub CLI extension:

gh extension install fini-net/gh-observer

This installs a precompiled binary for your platform - no Go toolchain required. To install a specific version:

gh extension install fini-net/gh-observer --pin v1.0.0

Or install via go install

If you prefer installing via Go:

go install github.com/fini-net/gh-observer@latest

Or build from source

To build from source:

git clone https://github.com/fini-net/gh-observer.git
cd gh-observer
just build

Usage

Auto-detect PR from current branch

gh-observer

Watch specific PR

gh-observer 123

Use in CI pipelines

# Wait for checks to complete and exit with their status
gh-observer && echo "All checks passed!"

Configuration

Create ~/.config/gh-observer/config.yaml to customize settings:

# Refresh interval for polling GitHub API
refresh_interval: 5s

# Color codes for terminal output (ANSI 256-color palette)
colors:
  success: 10  # Green - completed successfully
  failure: 9   # Red - completed with failure
  running: 11  # Yellow - currently in progress
  queued: 8    # Gray - waiting to start

See .config.example.yaml for reference.

Authentication

gh-observer uses GitHub authentication in this order:

1. GITHUB_TOKEN environment variable
2. gh CLI authentication (gh auth token)

Make sure you have either set up.

Supported Platforms

Precompiled binaries are available for:

• macOS: Intel (amd64) and Apple Silicon (arm64)
• Linux: x86-64 (amd64) and ARM64
• Windows: x86-64 (amd64)

All binaries include supply chain security attestations for verification.
