health

name	health
description	Check devkit health — which external CLIs (codex, gemini, gh, rtk, sg, gcli) are installed, which agents are available, which skills are ready to use. Use when asked about devkit health, devkit status, "is devkit working?", "what's installed?", "what devkit capabilities do I have?", diagnosing devkit setup issues, or running /devkit:health. Read-only diagnostic, safe to auto-invoke.

Devkit Status

Report on devkit installation health and available capabilities.

Checks

Plugins

Claude Code plugin checks:

echo "=== Plugin Status ==="
echo -n "codex plugin: " && (/codex:status >/dev/null 2>&1 && echo "installed" || echo "not installed")
echo -n "gemini plugin: " && (/gemini:status >/dev/null 2>&1 && echo "installed" || echo "not installed")

Under non-Claude hosts, report Claude plugin status as "not applicable" and check MCP config plus external CLIs instead.

Devkit Engine

Use the devkit_status tool to check workflow progress.

External CLIs

echo "=== CLI Status ==="
echo -n "codex: " && (command -v codex && codex --version 2>/dev/null || echo "not installed")
echo -n "gemini: " && (command -v gemini && gemini --version 2>/dev/null || echo "not installed")
echo -n "gh: " && (command -v gh && gh --version 2>/dev/null | head -1 || echo "not installed")
echo -n "rtk: " && (command -v rtk && rtk --version 2>/dev/null || echo "not installed (optional — 60-90% token savings)")
echo -n "gcli: " && (command -v gcli >/dev/null 2>&1 && echo "installed" || echo "not installed (optional — Google Workspace: Gmail, Calendar, Drive)")
echo -n "sg: " && (command -v sg >/dev/null 2>&1 && (sg --version 2>/dev/null || echo "installed") || echo "not installed (optional — AST-based repo mapping)")
echo ""
echo "=== RTK Status ==="
if command -v rtk >/dev/null 2>&1; then
  echo "installed: $(rtk --version 2>/dev/null)"
  echo "latest: check with 'brew outdated rtk' or 'rtk --version'"
  rtk gain 2>/dev/null | head -5 || echo "no session data yet"
else
  echo "not installed — install with: brew install rtk"
  echo "saves 60-90% tokens on Bash output (tests, git, ls, grep, etc.)"
fi

Local Runner

echo "=== Local Runner ==="
if [ "$DEVKIT_LOCAL_ENABLED" = "1" ]; then
  if command -v devkit-engine >/dev/null 2>&1; then
    devkit-engine probe-local 2>&1 || echo "probe failed — see output above"
  else
    echo "devkit-engine not in PATH — build with 'make build' from src/"
  fi
else
  echo "disabled (DEVKIT_LOCAL_ENABLED unset) — set to 1 to enable local inference"
fi

Agent Availability

List all agents from agents/ directory with their model and isolation settings.

Skill Availability

List all skills from skills/ directory, marking which ones need external CLIs:

## Devkit Status

### Plugins
| Plugin | Status | Skills |
|--------|--------|----------|
| codex | ✓ installed | /codex:rescue, /codex:review, /codex:result |
| gemini | ✗ not installed | /gemini:rescue, /gemini:review, /gemini:result |

### External CLIs (fallback if plugins not installed)
| CLI | Status | Required by |
|-----|--------|------------|

### Skills
| Skill | Status | Notes |
|-------|--------|-------|
| /tri-review | ⚠ partial | 2/3 agents available (no gemini) |
| /tri-debug | ⚠ partial | 2/3 agents available |

### Workflows
{list from workflows/ directory, or "none defined"}

Rules

• Check actual CLI availability with command -v, not just PATH
• If running under Codex, do not call Claude slash commands such as /codex:status; mark Claude plugin checks as not applicable
• Report versions where possible
• Clearly indicate which features work without external CLIs
• Show tri:* as "partial" if some but not all CLIs are present
