Syncro Soft, the developer of the industry-leading Oxygen XML suite of tools, is proud to announce the immediate availability of the Oxygen AI Positron 8.3 plugins for all major Oxygen XML suite products, including Oxygen XML Editor, Author, Developer (desktop and Eclipse distributions), Oxygen JSON Editor, Oxygen XML Web Author, and Oxygen Content Fusion.

Version 8.3 introduces stronger enterprise AI governance, a new project-aware development agent mode, expanded AI model support, and new XML automation capabilities. The release gives technical writers, XML developers, information architects, and enterprise administrators more control over AI behavior while improving assistance for technologies such as XSLT, Schematron, XPath, and DITA.

****************************************
What's New in Oxygen AI Positron 8.3
****************************************

* AI Governance with Event Hooks

Organizations can now monitor and control AI-driven workflows more closely with the introduction of a hook system for intercepting AI events, offering improved visibility and control over AI-driven workflows. Organizations can use hooks to audit AI activity, enforce governance policies, collect usage metrics, or block potentially risky operations before they are executed.

To simplify integration with existing enterprise tooling, the new Oxygen AI Positron Hooks add-on lets teams run external scripts when specific AI hook events occur. This makes it easier for administrators to connect AI lifecycle events to auditing, analytics, policy enforcement, and workflow automation systems.

* Dev Agent Chat Mode for XML Development Projects

The new Dev Agent chat mode gives XML teams a project-aware AI assistant for development tasks such as XSLT, Schematron, XPath, validation, and transformations. The Dev Agent can explore the project, propose a plan, and perform project-wide changes, while users remain in control of reviewing and deciding which modifications to keep.

* Specialized Development Skills

Version 8.3 adds specialized skills for development vocabularies including XSLT, XSD, Schematron, and XSpec. These skills help the AI produce more accurate code suggestions and reduce errors, enabling faster and more efficient development.

Custom skills can also now be packaged as ZIP archives with the .skill file extension. Once placed in the configured skills folders, these packages are automatically recognized and loaded by AI Positron, making it easier to distribute and share custom AI capabilities.

* Expanded Enterprise AI Connectivity

Organizations can now access newer OpenAI reasoning models through a new OpenAI Responses enterprise connector.

Version 8.3 also adds support for connecting to Model Context Protocol (MCP) HTTP servers that use OAuth authentication. Users can view a summary of running or failed servers in the Connection status section, with integrated login and logout controls.

For AWS users, the AWS Bedrock connector now supports AWS Credentials (Profile/SSO), offering a more secure authentication option than API keys.

* New AI Models and Improved Reasoning Visibility

Oxygen AI Positron 8.3 expands the list of available AI models for AI-assisted tasks, including:

- GPT-5.4 Thinking, GPT-5.5, and GPT-5.5 Thinking through the Positron Service or an OpenAI Responses enterprise connection.
- Claude Opus 4.8 Thinking and Claude Opus 4.8, designed for agentic workflows and complex multi-step tasks.
- Gemini 3.5 Flash through the Positron Service or the Vertex AI enterprise connection.

Users can now inspect reasoning from supported OpenAI thinking models in a collapsible chat section, improving transparency without cluttering the conversation.

Administrators can also manage which models are available for configured AI connections, define recommended defaults, and add models beyond the predefined list.

* Automatic Conversation Compaction for Longer AI Sessions

Long AI conversations can now continue more smoothly with the new automatic conversation compaction feature. When the allowed context usage reaches 70%, AI Positron summarizes older portions of the conversation and replaces them with a concise recap, preserving relevant context while allowing the discussion to continue.

Users can disable automatic compaction from the Preferences page or manually trigger compaction using the Context Consumption button in the footer of the AI Positron view.

* Fix Multiple Validation Issues at Once

The AI Positron Fix action can now be applied to multiple selected validation problems in the Results pane. This allows users to resolve several issues in a single AI-assisted operation, improving productivity when working with large or complex XML documents.

* More Flexible Custom AI Actions

When creating custom AI actions, users can now use Oxygen editor variables in the prompt_ref property. For example, a prompt can reference content from the user’s home folder, and the variable will be expanded automatically.

* New AI Tool Function for XPath Evaluation

AI Positron now includes an evaluate_xpath tool function that helps AI-assisted workflows access structured XML content more precisely.

* New XPath AI Functions for Advanced Automation

Two new AI extension functions, ai:chat() and ai:resolve-action(), are now available for XPath-based automation workflows, with full technical details available in the supporting documentation.
