SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The agent can edit the app's own source code — components, routes, styles, or scripts. This capability enables dynamic customization, bug fixes, feature tweaks, and UI adjustments without redeploying from external tooling.

Core Features & Use Cases

  • Self-modification permissions for app code with a clear taxonomy and safeguards.
  • Rollback and guardrails via a Git checkpoint pattern to ensure changes are recoverable.
  • Design guidance to expose edit points and maintainable interfaces to support agent-driven edits.

Quick Start

Design your app to expose safe edit points and implement a rollback strategy before applying changes.

FAQPage Schema
How do I enable an agent to modify application source code safely?▼

To enable agent-driven self-modification of application source code safely, expose clear edit points and implement a rollback strategy using a Git checkpoint pattern before applying changes.

What are the rollback safeguards for agent-driven code modification?▼

Rollback safeguards for agent-driven code modification use a Git checkpoint pattern to ensure all source code changes are recoverable, enforcing lint and typecheck validation after edits.

Can an agent edit components, routes, and styles without external redeployment?▼

Yes, agents can edit components, routes, styles, and scripts within the host application directly, enabling dynamic customization and bug fixes without redeploying from external tooling.

How do self-modifying code guardrails restrict changes to core internals?▼

Self-modifying code guardrails restrict agent edits to core internals and secrets by enforcing a taxonomy, applying typecheck and lint after edits, and maintaining strict rollback points.

Do I need to expose specific edit points before applying self-modifications?▼

Yes, you need to design your app to expose safe edit points and maintainable interfaces before applying agent-driven self-modifications to ensure changes remain structured and recoverable.

What is the best way to maintain typecheck and lint after agent edits?▼

The best way to maintain typecheck and lint after agent edits is to enforce a workflow that automatically runs validation checks after modifications and creates a rollback point if errors occur.
