+# Touch ID Local Testing Guide
+
+## Quick Start
+
+Test Touch ID authentication locally without installing globally:
+
+```bash
+cd /Users/USER/Documents/cli
+
+# Test read-only command (no Touch ID)
+HEROKU_TOUCH_ID_ENABLED=true ./bin/run.js config -a your-app
+
+# Test mutating command (Touch ID required)
+HEROKU_TOUCH_ID_ENABLED=true ./bin/run.js config:set TEST_KEY=test_value -a your-app
+```
+
+## What You'll See
+
+### Read-Only Commands (GET/HEAD)
+```bash
+HEROKU_TOUCH_ID_ENABLED=true ./bin/run.js apps:info my-app
+```
+- No Touch ID prompt
+- Command executes immediately
+
+### Mutating Commands (POST/PUT/PATCH/DELETE)
+```bash
+HEROKU_TOUCH_ID_ENABLED=true ./bin/run.js config:set KEY=value -a my-app
+```
+- Console shows: `🔐 Touch ID authentication required for PATCH request`
+- Native macOS dialog appears with "Authenticate to allow Heroku CLI PATCH request"
+- Use Touch ID fingerprint (or password as fallback)
+- Console shows: `Touch ID authenticated... ✓`
+- Command executes
+
+## Testing Methods
+
+### Method 1: Environment Variable (Recommended)
+```bash
+export HEROKU_TOUCH_ID_ENABLED=true
+./bin/run.js config:set KEY=value -a your-app
+./bin/run.js apps:create my-test-app
+```
+
+### Method 2: Per-Command
+```bash
+HEROKU_TOUCH_ID_ENABLED=true ./bin/run.js addons:create heroku-postgresql -a app
+```
+
+### Method 3: ht Command
+```bash
+# ht has Touch ID enabled by default
+./bin/ht config:set KEY=value -a your-app
+```
+
+## Debug Mode
+
+See what's happening behind the scenes:
+
+```bash
+DEBUG_TOUCH_ID=1 HEROKU_TOUCH_ID_ENABLED=true ./bin/run.js config:set KEY=val -a app
+```
+
+Output:
+```
+[Touch ID Debug] Init hook running, Touch ID enabled
+[Touch ID Debug] Found heroku getter, wrapping it
+[Touch ID Debug] Wrapping API client
+[Touch ID Debug] Method: PATCH, URL: /apps/app/config-vars, Requires auth: true
+🔐 Touch ID authentication required for PATCH request
+Touch ID authenticated... ✓
+```
+
+## Test Cases
+
+### Should NOT Require Touch ID
+- `heroku config -a app`
+- `heroku apps:info app`
+- `heroku logs -a app`
+- `heroku releases -a app`
+
+### SHOULD Require Touch ID
+- `heroku config:set KEY=value -a app`
+- `heroku apps:create new-app`
+- `heroku addons:create service -a app`
+- `heroku ps:scale web=2 -a app`
+- `heroku maintenance:on -a app`
+
+## Disabling Touch ID
+
+Even with `HEROKU_TOUCH_ID_ENABLED`, you can disable:
+
+```bash
+HEROKU_DISABLE_TOUCH_ID=true ./bin/run.js config:set KEY=val -a app
+```
+
+## Platform Behavior
+
+### macOS with Touch ID
+- Native dialog with fingerprint icon
+- Use Touch ID sensor or password
+
+### macOS without Touch ID  
+- Falls back to password-only authentication
+- Still uses secure LocalAuthentication framework
+
+### Linux/Windows
+- Touch ID checks automatically skipped
+- Shows warning: "Touch ID not available on this device"
+- Command proceeds normally
+
+## Troubleshooting
+
+### "Touch ID not available"
+- Check if your Mac has Touch ID hardware
+- Verify Touch ID is enabled in System Preferences
+- Try: `swift scripts/touch-id-auth.swift "Test"` directly
+
+### Authentication dialog doesn't appear
+- Verify `HEROKU_TOUCH_ID_ENABLED=true` is set
+- Check debug output with `DEBUG_TOUCH_ID=1`
+- Ensure you're running a mutating command (not GET)
+
+### Build required
+If you modified source files:
+```bash
+npm run build
+```
+
+## Production Notes
+
+- `ht` command is for testing only
+- Production usage: set `HEROKU_TOUCH_ID_ENABLED=true` in shell profile
+- Or create an alias: `alias ht='HEROKU_TOUCH_ID_ENABLED=true heroku'`
+- Touch ID has no effect on regular `heroku` command unless explicitly enabled
