# Procedural

The agent's rules of operation, instincts and "motor skills": model weights, code, and system prompt.

## At a glance

| Field | Value |
| --- | --- |
| Class | Memory layer |
| Scope | Persistent (rules / skills) |
| Examples | System prompts· skills· reflection |

## How it works

Reflection / meta-prompting: the agent evaluates its instructions against recent logs + user feedback and rewrites its own system prompt to improve future performance: an autonomous self-improvement loop.

## Watch out

Agents rarely touch weights/code; self-rewriting prompts can drift without guardrails.
