Our review
This skill checks whether a specific action is possible and diagnoses any blockers by testing permissions, configurations, and system prerequisites.
Strengths
- Quickly identifies missing permissions or misconfigurations.
- Provides a ready-to-use capability matrix for common services.
- Automates checks with simple shell scripts.
- Covers many macOS services (messaging, calendar, contacts, notes, etc.).
Limitations
- Requires target applications to be installed and configured in advance.
- Checks are macOS-specific (uses AppleScript).
- Only identifies blockers; does not resolve them.
Use this skill when you are unsure whether a certain action can be performed or to troubleshoot why it is failing.
Do not use it for actions that do not involve system permissions or third-party services.
Security analysis
SafeThe skill runs read-only diagnostic commands (pgrep, osascript, grep, ls) to check system capabilities. No destructive, exfiltrating, or obfuscated actions are included.

Capability Inventory
Full capabilities documentation: ~/.claude-mind/self/inventory.md
Access Patterns
# Read full inventory (comprehensive reference)
cat ~/.claude-mind/self/inventory.md
# Search for specific capability
grep -ni "search term" ~/.claude-mind/self/inventory.md
# List all sections
grep "^## " ~/.claude-mind/self/inventory.md
Quick Capability Matrix
| Capability | Method | Requires |
|------------|--------|----------|
| Send iMessage | AppleScript via Samara | Samara running, Automation permission |
| Send image | send-image script | Pictures folder workaround |
| Read calendar | AppleScript | Calendar permission |
| Write calendar | AppleScript | Calendar permission |
| Read contacts | AppleScript | Contacts permission |
| Read/write notes | AppleScript | Notes permission |
| Send email | AppleScript | Mail permission |
| Post to Bluesky | bluesky-post script | Credentials in config |
| Browse web | Playwright MCP | MCP server running |
| Take screenshot | screenshot script | Screen recording permission |
| Read Messages DB | Direct file access | Full Disk Access |
| Run shell commands | Bash | Always available |
| Read/write files | Direct | Always available |
Checking Specific Capabilities
Messaging
pgrep -q Samara && echo "Samara: OK" || echo "Samara: Not running"
~/.claude-mind/system/bin/message "test" --dry-run 2>/dev/null
Calendar
osascript -e 'tell application "Calendar" to get name of calendars' 2>&1
Contacts
osascript -e 'tell application "Contacts" to get name of first person' 2>&1
Notes
osascript -e 'tell application "Notes" to get name of first note' 2>&1
osascript -e 'tell application "Mail" to get name of first account' 2>&1
Bluesky
grep -q "bluesky" ~/.claude-mind/system/config.json && echo "Bluesky: Configured" || echo "Bluesky: Not configured"
Full Disk Access
ls ~/Library/Messages/chat.db 2>/dev/null && echo "FDA: OK" || echo "FDA: Missing"
Troubleshooting Flow
-
Identify the capability: What action is being attempted?
-
Check prerequisites:
- Is the required app/service running?
- Are permissions granted?
- Is configuration present?
-
Test minimally: Run simplest possible version of the action
-
Check logs: Look for error messages
log show --predicate 'process == "osascript"' --last 2m
- Report findings: What works, what doesn't, what to fix
Common Blockers
- "Not authorized to send Apple events": Missing Automation permission
- "Operation not permitted": Missing FDA or specific permission
- "Application isn't running": Need to launch the app first
- "No such file": Script or config missing
