Planck.Headless.Secrets.EnvFile (Planck.Headless v0.1.10)

Copy Markdown View Source

Default Planck.Agent.Secrets implementation that reads and writes API keys and service rules to .planck/.env and ~/.planck/.env.

Credentials are stored as KEY=value lines. Service rules are stored as # planck-service: comment lines, which standard .env parsers (including Skogsra's EnvBinding) ignore:

N8N_API_KEY=secret
# planck-service: api.n8n.com bearer N8N_API_KEY
# planck-service: api.custom.com api-key x-api-key CUSTOM_KEY

Both credential writes and service rule writes preserve the other section, so the two types of data coexist safely in the same file.
