Adding Secrets to TypeScript Golem Agents

Overview

Secrets are sensitive configuration values (API keys, passwords, tokens) stored per-environment and accessed via Secret<T> from @golemcloud/golem-ts-sdk. Unlike regular config fields, secret values are fetched on demand and managed separately from the agent config.

Declaring Secrets in the Config Type

Wrap sensitive fields with Secret<T> in your config type:

import { Config, Secret } from "@golemcloud/golem-ts-sdk";
 
type MyAgentConfig = {
  name: string;
  apiKey: Secret<string>;
  db: {
    host: string;
    port: number;
    password: Secret<string>;
  };
};

Using Secrets in Agent Code

Call .get() on a Secret<T> field to fetch the current value:

import { agent, BaseAgent, Config, Secret } from "@golemcloud/golem-ts-sdk";
 
@agent()
export class MyAgent extends BaseAgent {
  constructor(readonly id: string, readonly config: Config<MyAgentConfig>) {
    super();
  }
 
  connect(): string {
    const cfg = this.config.value;
    const key = cfg.apiKey.get();
    const pwd = cfg.db.password.get();
    return `Connecting to ${cfg.db.host}:${cfg.db.port}`;
  }
}

Managing Secrets via CLI

# Create secrets (--secret-type uses language-native type names)
golem agent-secret create apiKey --secret-type string --secret-value "sk-abc123"
golem agent-secret create db.password --secret-type string --secret-value "s3cret"
 
# List, update, and delete
golem agent-secret list
golem agent-secret update-value apiKey --secret-value "new-value"
golem agent-secret delete apiKey

Note: For update-value and delete, you can also use --id <uuid> instead of the positional path.

Secret Defaults in golem.yaml

For development environments, define secret defaults in golem.yaml. These are not used in production:

secretDefaults:
  local:
    apiKey: "dev-key-123"
    db:
      password: "dev-password"

Key Points

• Secret<T> fields are not loaded eagerly — call .get() to fetch the current value.
• Secret values are stored per-environment, not per-agent-instance.
• Secrets are not stored in the config section of golem.yaml — use secretDefaults for dev environments only.
• Missing required secrets cause agent creation to fail.
• The --secret-type flag accepts TypeScript type names: string, s32, boolean, string[] (JSON-encoded analysed types like '{"type":"Str"}' are also supported as a fallback).
• If the agent also needs non-secret typed config guidance, use golem-add-config-ts alongside this guide.
