How to run a health check on your Claude Code setup with Claude Code Templates

Diagnose your Claude Code install and manage plugins and permissions from one dashboard.

Short answer: Run npx claude-code-templates@latest --health-check for diagnostics; then run npx claude-code-templates@latest --plugins to view marketplaces, installed plugins and permissions; Apply a setting such as npx claude-code-templates@latest --setting performance/mcp-timeouts --yes if MCP calls time out. All steps.

Who it is forA developer whose Claude Code feels slow or misconfigured after adding many plugins and MCP servers.

The problemPlugins, marketplaces and settings pile up and it is hard to see what is installed or why something times out.

The outcomeA diagnostics report on your installation and a dashboard of marketplaces, plugins and permissions.

What you need first

  • Claude Code installed
  • Node.js with npx
  • Accounts or keys for any external service an MCP integration connects to, such as GitHub or PostgreSQL

Steps

  1. Run npx claude-code-templates@latest --health-check for diagnostics
  2. Run npx claude-code-templates@latest --plugins to view marketplaces, installed plugins and permissions
  3. Apply a setting such as npx claude-code-templates@latest --setting performance/mcp-timeouts --yes if MCP calls time out
  4. Re-run the health check to confirm

Prompt for your agent

Run the davila7/claude-code-templates health check on my Claude Code installation and open the plugin dashboard. Summarise any problems, and only apply the mcp-timeouts setting if MCP timeouts are listed.

Caveat. Settings change Claude Code's behaviour for the project; note what you change so you can undo it.
