Troubleshooting & Common ErrorsFAQ

Common connection errors and verified fixes for no-crd

Getting 'connection closed' or exit code 1 in Cursor / Claude Code for no-crd?

Usually caused by missing runtime paths or IDE environment inheritance. Fix steps: 1. Verify Node.js 18+ (npx) or Python 3.10+ (uvx) is installed; 2. Run 'which npx' or 'which uvx' in terminal, and replace 'command' with absolute path; 3. Reload or restart the client window after modifying config.

Fix Snippet
# Check binary path in terminal:
which npx
node -v
Getting 'spawn npx ENOENT' or 'command not found'?

The editor background process does not inherit your full terminal PATH. Solution: Globally install the package, or set the absolute binary path (e.g. C:\Program Files\nodejs\npx.cmd on Windows, or /usr/local/bin/npx on macOS).

Missing required environment variable or authentication failure?

no-crd requires environment variables (KUBECONFIG、BASE_URL、STATELESS、TLS_CERT、TLS_KEY、TLS_CA、NODE_TLS_REJECT_UNAUTHORIZED、REGISTRY_URL、TEMPLATES_DIR、BUILTIN_TEMPLATES、AUTH_ENABLED、JWT_VERIFICATION_REQUIRED、JWT_SECRET、JWT_PUBLIC_KEY、JWKS_URI、INTROSPECTION_ENDPOINT、OAUTH_CLIENT_ID、OAUTH_CLIENT_SECRET、JWT_AUDIENCE、AUTH_ISSUER、AUTH_SUB_JSONPATH、AUTH_ADMIN_ROLE、AUTH_ADMIN_USERS、PROXY_SESSION_TTL、PROXY_SESSION_SECRET、UI_ENABLED、THEMES_DIR、THEMES_CONFIGMAP、DOCS_DIR、OAUTH_DISCOVERY_URL、OAUTH_LOGIN_METHOD、UI_TITLE、UI_SUBTITLE). Ensure you have added valid keys under the 'env' object in your config file without trailing whitespace.

Fix Snippet
// .cursor/mcp.json 或 claude_desktop_config.json
{
  "env": {
    "API_KEY": "your_actual_key_here"
  }
}

Planning with files

v3.23.0

SkillClawHub44.6k

io.clawhub.othmanadi/planning-with-files

Persistent file-based planning for multi-step AI-agent work. Keeps task_plan.md, findings.md, and progress.md on disk; lifecycle hooks inject selected project planning context. Automatic recovery reads project planning files only. Explicit session-catchup.py --metadata reads same-project local agent session records and emits aggregate counts only; --replay may emit bounded nonce-framed excerpts. Optional gated mode can request continuation only when the host supports it and never runs commands declared in Markdown. The skill has no network upload path. Use for research or work needing 5+ tool calls.
