This piece documents Lain, an autonomous AI agent in the Ekioo ecosystem. Ekioo runs AI agent fleets across Bloomii (constructive journalism), Kalceo (regulatory B2B SaaS), and KittyClaw (the kanban orchestrator coordinating all production projects).

An agent that no longer just assists

Until now, Lain could browse the web, manipulate files, execute code. But whenever it needed to click a button in a Windows application or fill a form with no API, the agent hit a wall.

With version 0.23, that barrier is gone. Lain can now directly use the Windows graphical interface — clicks, keyboard input, scrolling, drag-and-drop, keyboard shortcuts. She sees what she's doing through real screenshots, with multi-monitor support.

The computer becomes an environment for action, not just a terminal.

🖱 Autonomous PC control

This is the most significant change in this release.

In practice, Lain can now:

  • Automate tools with no API — business software, legacy applications, proprietary interfaces
  • Navigate complex interfaces — menus, modal windows, tabs
  • Chain actions just like a human sitting at a screen

To make decisions, the agent captures real screenshots and interprets them. Multi-monitor support enables working with realistic setups.

📂 File upload in the browser

During web browsing tasks, Lain can now upload files to web forms.

It sounds simple, but it's an essential building block. Many real-world processes involve web portals with documents to submit. Without this capability, the agent was stuck at the critical step. Now it can complete end-to-end action chains.

🧠 New LLM configuration system

Model management has been completely redesigned:

  • Built-in model catalog — no need to look up model identifiers
  • Per-role configuration — planning, execution, summarization... each step can use the most suitable model
  • Automatic migration from the old format

A single model isn't enough to do everything efficiently. Role-based separation optimizes reasoning quality, execution speed and API costs.

GPT-5.4 support

This release gains an extra dimension with GPT-5.4 support, which significantly improves:

  • Planning for complex tasks
  • Interface understanding through screenshots
  • Action reliability in multi-step chains

Plans become more coherent, navigation sequences more robust against interface variations.

⚡ Progressive tool loading

Infrequently used tools are no longer loaded at startup, but on demand. Less unnecessary context, better performance, more responsive agent.

Reducing contextual noise directly improves decision stability — especially with a powerful model like GPT-5.4.

More transparency

The interface has been improved to make execution more readable:

  • Visualization of plan steps during execution
  • Display of the agent's last thought
  • Button to see the full detail of tools used

Understanding what the agent does — and why — is essential for building trust in an autonomous system.

Stronger planning

The planning system has been hardened:

  • Limit raised to 20 steps
  • Stricter instructions to avoid vague actions
  • Better recovery after user choices
  • Manually activated tools stay unlocked between sessions

The direction

Taken together, these changes paint a clear trajectory. Lain is evolving toward an agent that understands goals, plans, acts in the real environment and adapts to interactions.

An autonomous software collaborator, not a chatbot.

Version 0.23 lays the foundations for running an agent in a real digital workspace — and the results with GPT-5.4 show that the model is starting to match the ambition.
