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
Example Output
PR #123: Add new feature
Startup Phase (37s elapsed):
⏳ Waiting for Actions to start...
💡 GitHub typically takes 30-90s to queue jobs after PR creation

PR that was just created

This was sped up 2x. In this example, the Claude check fails, illustrating how
error log output is integrated alongside the list of jobs.
PR that was just created with GHAs that use descriptions

The Super-Linter and a few other
GitHub Actions utilize the description field to convey success or failure. Our
extension doesn't show descriptions for successful checks and displays them for
cases with errors to be consistent with the GitHub Actions that make it easier
to show the right bit of the logs. Since we don't try to show the logs for
super-linter, you're "stuck" clicking on the title of the job in your terminal
and it will open up in your favorite web browser.
This was sped up 10x.
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
Our primary focus is on improving the interactive experience, but we also
set the exit code for the process in a potentially useful way.
# 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:
GITHUB_TOKEN environment variable
gh CLI authentication (gh auth token)
Make sure you have either set up.
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.
Development
This project uses just for task automation:
# Build the binary and install locally as gh extension
just build
# Run on current PR
gh observer
# Create a PR

# Merge a PR
