Configuration: silo.yaml

The silo.yaml file is the central configuration for your local SILO environment. It is typically located in ~/.silo/silo.yaml.

Global Settings

Key	Type	Description
master_key_strategy	string	How to handle the master key: env, keyring, or prompt.
max_workers	int	Maximum concurrent tool executions (default: 10).
hub_path	string	custom path for the skill hub.

Pruning Logic

Configure how SILO cleans up old skill data and virtual environments.

pruning:
  enabled: true
  keep_days: 14            # Removes skills not used in X days
  delete_unused_venv: true # Deletes .venv while keeping the skill source

Secret Mappings

Map local skill secret requirements to global encrypted values.

mappings:
  - namespace: "fin-ops"
    secrets:
      API_KEY: "CLAUDE_PRODUCTION_KEY"

In this example, the fin-ops skill will receive the value stored in the global vault under CLAUDE_PRODUCTION_KEY when it requests require("API_KEY").
