What problem does it solve? When ClinePass (Cline Credits) is unavailable or exhausted, agents lose their primary LLM provider. This Skill sets up BigModel GLM-5.2 as a system-wide fallback so all agents keep working without manual reconfiguration or hardcoded credentials. ## Core Features & Use Cases - Automated Fallback Setup: A bash script stores the API key in a mode-600 secrets file, creates an operator-local env bundle, and tests the BigModel endpoint connection. - Env-Var-Only Authentication: Reads the key from $GLM52_API_KEY or $OPENCLAW_MODELS_PROVIDERS_BIGMODEL_APIKEY and fails fast with a clear error if unset, making it safe for unattended CI runs. - Defined Failover Chain: Documents a four-tier fallback order (ClinePass, BigModel GLM-5.2, OpenRouter free tier, local Ollama) with timeout, retry, and exit-code policies. - Use Case: An operator whose Cline Credits run out mid-session exports GLM52_API_KEY and runs the setup script, restoring GLM-5.2 access for every agent on the next startup. ## Quick Start Set the GLM52_API_KEY environment variable and ask the agent to run the GLM-5.2 fallback setup script, then verify the connection reports healthy.
