# Logic & Descriptions

> Every Blueprint has two sides — the plain-language descriptions and the executable logic. Keep them aligned as you edit, with help from the Lab Agent.

# Keeping logic and descriptions aligned

Every Blueprint in Leapter has two sides:

* **Descriptions** — the project description, Blueprint descriptions, section titles, and the labels around each node, all written in plain language.
* **Logic** — the diagram of decisions, assignments, calls, and returns that actually executes.

The [Specification view](/fundamentals/leapter-canvas/specification-view) shows both together, description next to logic. When you build a Blueprint the two are aligned, but over time they drift: you tweak a condition without updating the description, you rewrite a description without changing the logic, or a teammate edits one side without touching the other.

## Bringing the two sides back in line

The fastest way to reconcile them is to ask the **[Lab Agent](/fundamentals/change-your-blueprint/lab-agent)** in plain language:

* *"Update the section descriptions to match what the logic actually does."* — when the logic is the source of truth and the wording fell behind.
* *"Make the logic follow the description for the bulk-discount section."* — when a domain expert updated the spec text and you want the diagram to catch up.

Because the agent edits both the diagram and the surrounding text, and can [run your tests](/fundamentals/test-your-blueprint) to check the result, it keeps the two sides consistent in one step.

For smaller, hands-on adjustments you can also:

* Make a scoped change with **[AI editing (Ctrl+I)](/fundamentals/change-your-blueprint/ai-editing)**.
* Edit a title, description, or expression yourself with **[inline editing](/fundamentals/change-your-blueprint/inline-editing)**.

## Tips

* **Reconcile before you share.** Before sending a [public link](/fundamentals/sharing) to a stakeholder, ask the agent to bring the descriptions in line with the logic so the spec they read matches what runs.
* **Reconcile after big edits.** After restructuring a diagram or rewriting a section, check that the other side hasn't fallen behind.
* **Review before applying.** In the agent's Approval mode you see every proposed change before it lands.

## What to do next

* **[Lab Agent](/fundamentals/change-your-blueprint/lab-agent)** — reconcile descriptions and logic by chatting with AI
* **[AI Editing](/fundamentals/change-your-blueprint/ai-editing)** — make a targeted change with a natural-language prompt
* **[Inline Editing](/fundamentals/change-your-blueprint/inline-editing)** — edit titles, descriptions, and expressions in place
