Summary of agent

This agent can write and rewrite its own rules, allowing you to mold its behavior. It receives rules from a database as system instructions and has tools to create, edit, or delete them. This is a great baseline for new agent builds.

You can tell it things like "Next time, use present tense when talking about this subject" and it will use a tool to save this as a rule, then receive that instruction in all future iterations.

How to start using it

Option 1: With a Postgres database (eg, Supabase)

1. Supabase Schema: Create a table (eg, agent_rules ) with the following columns:
   • id : bigint (Primary Key, auto-incrementing)
   • created_at : timestamp with time zone (Default: now() )
   • rule_text : text
   • agent : text
2. Workflow Updates:
   • Update the Postgres credentials in the "Get rules from database," "Insert rule into database," and "Execute query on rule database" nodes.
   • Update the agent value (currently 'TestAgent') in the "Get rules from database" and "Insert rule into database" nodes if you want a different agent name.
   • Update the Anthropic API credentials .

Option 2: With Google Sheets

1. Google Sheet Setup: Create a Google Sheet with columns for rule_text and agent .
2. Workflow Updates:
   • Example Google Sheets nodes are included. You will need to:
     • Connect your Google Sheets credentials .
     • Select your Google Sheet (with rule_text and agent columns) in all relevant Google Sheets nodes.
     • Replace the existing Postgres nodes ("Get rules from database", "Insert rule into database", "Execute query on rule database") with the configured Google Sheets nodes.
   • Update the agent value (currently 'TestAgent') in the Google Sheets nodes if you want a different agent name.
   • Update the Anthropic API credentials .
   • Agent Instructions: Update the agent's system message and remove the database schema section as it is no longer relevant
