Refactor remaining skills with resources pattern and allowed-tools

- k8s-quick-status: Add scripts/quick-status.sh, allowed-tools
- sysadmin-health: Add scripts/health-check.sh, allowed-tools
- usage: Add scripts/usage_report.py, simplify SKILL.md
- programmer-add-project: Add allowed-tools

All skills now:
- Have executable scripts for main operations
- Use allowed-tools to restrict capabilities
- Have improved descriptions with trigger phrases
- Follow the "Skill with Bundled Resources" pattern

 # K8s Quick Status Skill
 
 Performs a lightweight health pulse check on the Raspberry Pi Kubernetes cluster.
 
+## Quick Command
+
+```bash
+~/.claude/skills/k8s-quick-status/scripts/quick-status.sh
+```
+
+Or run individual checks:
+
+```bash
+# Node status
+kubectl get nodes -o wide
+
+# Unhealthy pods
+kubectl get pods -A --field-selector=status.phase!=Running,status.phase!=Succeeded
+
+# Warning events
+kubectl get events -A --field-selector=type=Warning --sort-by='.lastTimestamp' | tail -10
+
+# ArgoCD apps
+argocd app list
+```
+
 ## Checks Performed
 
-### Node Status
-- Node readiness (`kubectl get nodes`)
-- Node conditions (MemoryPressure, DiskPressure, PIDPressure)
-
-### Pod Health
-- Unhealthy pods (`kubectl get pods -A --field-selector=status.phase!=Running`)
-- High restart counts (pods with >5 restarts)
-
-### Recent Events
-- Warning events in last hour (`kubectl get events -A --field-selector=type=Warning --sort-by='.lastTimestamp'`)
-
-### ArgoCD Status
-- Application sync status (`argocd app list`)
-- Any OutOfSync or Degraded apps
+| Check | Command | What It Shows |
+|-------|---------|---------------|
+| Nodes | `kubectl get nodes` | Readiness, conditions |
+| Pods | `kubectl get pods -A` | Unhealthy pods |
+| Restarts | jsonpath query | Pods with >5 restarts |
+| Events | `kubectl get events` | Recent warnings |
+| ArgoCD | `argocd app list` | Sync status |
 
 ## Output Format
 
-Report as structured summary with:
-- Overall status (healthy/warning/critical)
-- Node summary table
-- Unhealthy pods list (if any)
-- ArgoCD app status
-- Immediate concerns (if any)
-
-## Autonomy
-
-This skill is read-only and can run without confirmation.
+Report as structured summary:
+- **Overall status**: healthy/warning/critical
+- **Node summary**: table of nodes
+- **Issues**: unhealthy pods, high restarts
+- **ArgoCD**: sync status
+- **Concerns**: immediate action items
 
 ## When to Use
 
-Use this skill for a quick pulse check. For comprehensive analysis with metrics and detailed recommendations, use the `/cluster-status` command which invokes the full `cluster-health-check` workflow.
+- Quick pulse check: use this skill
+- Comprehensive analysis: use `/cluster-status` command
+
+## Autonomy
+
+Read-only - runs without confirmation.
