What it does

Health Check is an agent skill from hoangsonww/Claude-Code-Agent-Monitor. Run comprehensive health checks on the Claude Code Agent Monitor system. Validates dashboard API, database, WebSocket, hooks, and disk usage. Use to verify the monitoring setup is working correctly.

Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Backend & APIs, covering Realtime and WebSockets. The repository describes itself as: 🚀 A real-time monitoring dashboard for Claude Code & Codex, built with SQLite3, Node.js, Express, React, Vite, TailwindCSS, & WebSockets. It tracks sessions, agent activity… The licence is MIT.

When your agent uses it

  • Verify the monitoring setup is working correctly
  • Tasks that involve Realtime and WebSockets

Example prompts

  • “/health-check”

Requirements

  • Node.js

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. API Health
  2. Database Health
  3. WebSocket Health
  4. API Endpoint Validation
  5. Hook Integration
  6. Disk & Resource Usage (deep mode only)
  7. Data Freshness

What it can do on your machine

Read from SKILL.md and the folder at commit a06db03. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Health Check loads about 706 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 208 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~706

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Health Check

Run a comprehensive health check on the Agent Monitor system.

Input

The user provides: $ARGUMENTS

This may be:

  • "full" or empty (default: run all checks)
  • "quick" for a fast connectivity check
  • "deep" for extended checks including database integrity

Procedure

Run health checks in this order:

1. API Health
bash
curl -sf http://localhost:4820/api/health
  • Verify HTTP 200 response
  • Check response time (<500ms expected, <1000ms acceptable)
  • Confirm JSON response body
2. Database Health
bash
curl -sf http://localhost:4820/api/stats
  • Verify stats endpoint returns valid data
  • Check that counts are non-negative integers
  • Verify database file exists and has reasonable size
3. WebSocket Health
  • Check that the WebSocket server is listening
  • Verify WebSocket upgrade is supported on the dashboard port
4. API Endpoint Validation

Test each major endpoint:

bash
curl -sf http://localhost:4820/api/sessions?limit=1
curl -sf http://localhost:4820/api/events?limit=1
curl -sf http://localhost:4820/api/analytics
curl -sf http://localhost:4820/api/pricing
curl -sf http://localhost:4820/api/settings/info
5. Hook Integration
  • Verify hook handler script exists
  • Check hooks are configured in ~/.claude/settings.json
  • Verify the handler script targets the correct dashboard URL
6. Disk & Resource Usage (deep mode only)
  • Database file size
  • Log file sizes (if any)
  • Available disk space
  • Node.js process memory usage (if accessible)
7. Data Freshness
  • Time since last event ingested
  • Time since last session created
  • Check for stale active sessions (active but no events in >1 hour)

Output Format

Present as a system health dashboard:
