Wire encrypted credentials to environment variables using the credential: convention. Use when setting up LLM provider keys (ANTHROPIC\_API\_KEY, OPENAI\_API\_KEY) or any env var that should come from encrypted credentials.

## From README

Credentials as Environment Variables When to Use This Skill Setting up ANTHROPICAPIKEY or OPENAIAPIKEY from encrypted credentials Wiring any credential path to a process.env variable automatically Migrating from plaintext .env secrets to encrypted credentials Understanding why an env var is being resolved at worker startup The credential: Convention Any env var whose value starts with credential: is resolved from encrypted credentials at worker startup. The format is: Example .env Encrypted credentials (config/credentials.yml.enc) How It Works When the worker starts, every env var set to credential: is replaced with the decrypted value at that path. By the time a workflow runs, ANTHROPICAPIKEY holds the real key and LLM SDKs read it as usual. Values come from the global credentials for the current environment: config/credentials/ .yml.enc when it exists, otherwise config/credentials.yml.enc.
