### Top-Level
| Command | Aliases | Description |
|---------|---------|-------------|
| `/pa` | `/assistant`, `/ask` | Personal assistant entrypoint |
| `/programmer` | | Code development tasks |
| `/gcal` | `/calendar`, `/cal` | Google Calendar access |
| `/usage` | `/stats` | View usage statistics |
### Kubernetes (`/k8s:*`)
| Command | Description |
|---------|-------------|
| `/k8s:cluster-status` | Quick cluster health overview |
| `/k8s:deploy` | Deploy applications to cluster |
| `/k8s:diagnose` | Diagnose Kubernetes issues |

| Command | Description |
|---------|-------------|
| `/sysadmin:health` | System health check |
| `/sysadmin:update` | System package updates |
| `/sysadmin:autonomy` | Set autonomy level for session |
## Command Format
```yaml
---
name: command-name
description: What this command does
aliases: [alias1, alias2]
invokes: skill:skill-name # or workflow: or agent:
---
# Command Title
Instructions for Claude when command is invoked.
```
## Command vs Skill
| Aspect | Command | Skill |
|--------|---------|-------|
| **Invocation** | User types `/command` | Claude decides automatically |
| **Discovery** | Explicit | Based on description matching |
| **Use case** | Quick actions, shortcuts | Domain expertise, workflows |

```
Namespaced commands use subdirectories (e.g., `k8s/deploy.md` → `/k8s:deploy`).
## Adding Commands
1. Create `commands/name.md` (or `commands/namespace/name.md`)
2. Add YAML frontmatter with name, description, invokes
3. Write instructions in Markdown body
4. Update `component-registry.json` if needed for routing

# Skills
Agent skills that extend Claude's capabilities. Model-invoked (Claude decides when to use them).
## Available Skills
| Skill | Description | Scripts |
|-------|-------------|---------|
| `gmail` | Gmail read access | `check_unread.py`, `check_urgent.py`, `search.py` |
| `gcal` | Google Calendar access | `agenda.py`, `next_event.py` |
| `k8s-quick-status` | Kubernetes cluster health | `quick-status.sh` |
| `sysadmin-health` | Arch Linux health check | `health-check.sh` |
| `usage` | Session usage tracking | `usage_report.py` |
| `programmer-add-project` | Register projects | (workflow only) |
## Skill Structure
Each skill uses the "Resources Pattern":
```
skills/skill-name/
├── SKILL.md # Main instructions (required)
├── scripts/ # Executable helpers
│ ├── action1.py
│ └── action2.sh
└── references/ # Documentation
└── patterns.md
```
## Skill Format
```yaml
---
name: skill-name
description: What it does. Use when [trigger conditions].
allowed-tools:
- Bash
- Read
---
# Skill Name
## Quick Commands
```bash
./scripts/main-action.py [args]
```
## Request Routing
| User Request | Action |
|--------------|--------|
| "do X" | Run script with args |
## Policy
- Read-only / Write allowed
- Model tier preferences
```
## Key Elements
### Description
Critical for discovery. Include:
- What the skill does
- When Claude should use it (trigger phrases)
### allowed-tools
Restricts which tools Claude can use:
- `Bash` - Run commands/scripts
- `Read` - Read files
- `Write` - Write files
- `Edit` - Edit files
### Scripts
Standalone executables that do the work:
- Python: `#!/usr/bin/env python3`
- Bash: `#!/bin/bash`
- Must be executable: `chmod +x`
### References
Supporting documentation:
- Query patterns
- API reference
- Examples
## Adding a Skill
1. Create `skills/name/SKILL.md`
2. Add scripts to `skills/name/scripts/`
3. Make scripts executable
4. Update `component-registry.json` with triggers
5. Test: ask Claude something that should trigger it
