Check if happy-cli is on the latest version.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Happy CLI Version Check
Check if the installed happy-cli is on the latest version and report status.
---
## Step 1: Get Installed Version
```bash
happy --version 2>&1 | grep -oP '(?<=happy version: )\S+' || echo "NOT_INSTALLED"
```
---
## Step 2: Get Latest Version from GitHub
Use the GitHub API to get the latest release:
```bash
curl -s https://api.github.com/repos/slopus/happy-cli/releases/latest | grep -oP '"tag_name":\s*"v?\K[0-9.]+' || echo "FETCH_FAILED"
```
---
## Step 3: Compare and Report
Compare the versions and output status:
### If versions match:
```
Happy CLI Status: UP TO DATE
Installed: {version}
Latest: {version}
```
### If update available:
```
Happy CLI Status: UPDATE AVAILABLE
Installed: {installed_version}
Latest: {latest_version}
To update: npm update -g happy-coder
```
### If not installed:
```
Happy CLI Status: NOT INSTALLED
To install: npm install -g happy-coder
```
---
## Step 4: Check Settings Status
Check if happy settings are valid:
```bash
cat ~/.happy/settings.json 2>/dev/null
```

How to install
mdr add cooneycw/claude-power-pack/cpp-happy-check@sha256:c28c3a519df0e49fThe line at the top of this page pins the label git:20260718.7f453b7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
