Methods for Using the GLM Coding Plan in Claude Code (docs.z.ai)

Anthropic published a practical guide for using the GLM Coding Plan inside Claude Code, covering installation, environment configuration, model selection, and troubleshooting. Key setup steps: install Claude Code (requires Node.js 18+ and elevated permissions if needed), run the provided configuration script which updates ~/.claude/settings.json with environment variables, then launch claude from a terminal and grant file access when prompted. The guide also points to Vision MCP and Search MCP server docs for integrating vision and search capabilities. Technically important details: default internal model mappings are ANTHROPIC_DEFAULT_OPUS_MODEL → GLM-4.6, ANTHROPIC_DEFAULT_SONNET_MODEL → GLM-4.6, and ANTHROPIC_DEFAULT_HAIKU_MODEL → GLM-4.5-Air. Hardcoding those mappings is discouraged because it prevents automatic upgrades to newer GLM models; deleting the model-mapping keys in settings.json lets Claude Code revert to the latest defaults. Troubleshooting tips include restarting Claude Code, removing a malformed ~/.claude/settings.json to regenerate it, and validating JSON syntax. The documentation recommends using the latest Claude Code (compatibility verified with v2.0.14) to ensure smooth operation and access to current GLM models and integrations.
