Use AI Assistance on CAST Imaging Documentation

Set Up AI Integration

Mon, 01 Jan 0001 00:00:00 +0000

Before you start


Who this is for	CAST Imaging administrator
Role required	Admin or Super Admin
Prerequisites	An OpenAI or Azure OpenAI API key; internet access to the AI provider (or a proxy)

Step 1: Get an API key

OpenAI: Create an account at openai.com, go to View API keys, and click Create new secret key.

Azure OpenAI: You need an Azure subscription with access to Azure OpenAI. Deploy a GPT-4 model. Collect the API key, endpoint URL, and deployment name.

Explain an Object with AI

Mon, 01 Jan 0001 00:00:00 +0000

Before you start


Who this is for	Developer, architect
Role required	Viewer or higher
Prerequisites	AI integration set up by administrator; source code viewer configured

Step 1: Right-click an object

At Objects level, right-click any object and select Explain with AI.

[TODO: Screenshot of the context menu]

Step 2: Read the explanation

The source code appears in the Legend panel. The AI explanation loads below it. The explanation first appears as a short summary.

Explain an Object in its Call Context

Mon, 01 Jan 0001 00:00:00 +0000

Before you start


Who this is for	Developer
Role required	Viewer or higher
Prerequisites	AI integration set up; source code viewer configured

When to use this feature

Use Explain Object Context with AI (rather than plain Explain) when the object’s purpose is only clear when you see how it is used. For example, a utility method called from many places has different meaning depending on which callers are relevant to your investigation.

Generate an AI Summary for a Scope

Mon, 01 Jan 0001 00:00:00 +0000

Before you start


Who this is for	Developer, architect
Role required	Viewer or higher
Prerequisites	AI integration set up; application imported

Step 1: Open the scope

Go to the scope you want to summarize: Application, Transaction, Module, or Data Call Graph.

Step 2: Start AI summary generation

In the toolbar or left panel, click Generate AI summary.

[TODO: Screenshot showing the button location]

Step 3: Configure options

Option	Description
Filter by complexity	Only summarize objects above a cyclomatic complexity threshold. Useful for large scopes — focus AI on the most complex parts.
Generation method	Graph Representation: includes call relationships. Exclusive Object: summarizes each object independently.

Step 4: Wait for the summary

The AI processes objects in the scope. For large scopes, this can take several minutes. Monitor progress in the status bar.

Use the AI Chatbot Assistant

Mon, 01 Jan 0001 00:00:00 +0000

Before you start


Who this is for	Any user
Role required	Viewer or higher
Prerequisites	AI integration set up with GPT-4

What data is shared

The chatbot shares graph metadata (object names, relationships, module names) with the AI provider. It does not share source code. This is different from the Explain features, which do share code snippets.

Open the chatbot

Click the chatbot icon in the toolbar.

Generate an AI Functional Report

Mon, 01 Jan 0001 00:00:00 +0000

Before you start


Who this is for	Architect, project manager
Role required	Viewer or higher
Prerequisites	AI integration set up; application imported

What the report contains

The AI Functional Report is a document that describes the application in plain language. It covers:

Application overview and technologies
Module descriptions
Transaction summaries
Data call graph summaries

The report is intended for stakeholders who do not have access to CAST Imaging.

Bulk-Generate AI Summaries

Mon, 01 Jan 0001 00:00:00 +0000

Before you start


Who this is for	Architect, developer
Role required	Editor or higher
Prerequisites	AI integration set up; application imported

Step 1: Start bulk generation

In the toolbar, click Bulk AI summary.

[TODO: Screenshot]

Step 2: Select the target scope

Choose which items to summarize:

All modules
All transactions
All data call graphs
A combination

Step 3: Configure generation options

[TODO: Same options as Generate AI summary — generation method, complexity filter]
