Changelog

v0.5.6 — February 21, 2026

Focused on making agent setup and installation more reliable — fewer manual steps, better error recovery.

What's Better

In-process Claude installer — Claude Code can now install directly without opening a separate terminal
Automatic Bun lockfile recovery — corrupted bun install states are detected and fixed automatically
Unix binary permissions handled — macOS quarantine clearing, chmod, and executable verification happen automatically
Bundled adapters copy to writable directory — no more issues with read-only build folders
Reasoning effort controls are more reliable — properly handles agents with non-standard config identifiers
Full keyboard navigation in dialogs — arrow keys, Tab, and Enter work in permission and question prompts
Better OpenRouter setup messaging — clearer error states for missing keys, credit hints, install commands with copy button

Other Improvements

Session deletion correctly resolves native vs. Unreal session IDs
Settings reorganized with clearer "Agent Process Overrides" section
File attachment handling centralized and improved
Claude Code and Codex agent docs updated

v0.5.5 — February 18, 2026

Focused polish update after v0.5.3 — better day-to-day reliability, smoother agent setup, and fewer “stuck” workflows.

What’s Better

More reliable editing in UE 5.5 — improved stability when working with advanced rigging/VFX assets
Major agent stability upgrade for GitHub Copilot CLI + Gemini CLI — significantly improved startup/session reliability and fewer connection/model issues
Fewer broken agent starts overall — session startup and model selection are now more dependable across workflows
Setup flow is smoother — restart action is now available directly from setup when needed
Update checks are easier — added manual Check for Updates inside Settings → About
Typing in chat behaves better — improved non-English/IME input behavior and keyboard handling while chatting
External links open correctly — popups now open in your system browser instead of creating awkward in-editor windows

Stability Improvements

Reduced edge-case session hangs and tool dead-ends
Improved backend request/session handling to keep long-running agent workflows stable

v0.5.0 — February 16, 2026

Our biggest update yet — new UI, smarter agents, zero-setup install, and you can now continue conversations across different agents.

Completely New UI

The chat interface has been rebuilt from the ground up. Everything is faster, cleaner, and more capable.

Onboarding wizard — new users get a guided setup flow instead of figuring things out manually
Session sidebar — browse, resume, and manage all your chat sessions in a collapsible sidebar
Rich asset previews — when the agent reads an asset, results are now rendered with color-coded sections by asset type instead of raw text
See what the agent is planning — a dedicated plan panel shows the agent's thinking and steps as it works
Source control at a glance — see your current Git branch, pending changes, and submit directly from the chat window
Browse and search models — pick from all available models with a searchable browser and descriptions
Control reasoning depth — adjust how much the agent thinks before responding (off / low / medium / high / max)
Live usage tracking — see token counts, session cost, and how much of the context window is used in real time
UI updates without plugin rebuilds — interface improvements ship independently from plugin versions

Agents Are Smarter with Fewer Tools

We consolidated 27+ tools down to about 15. Instead of the agent choosing between edit_ik_rig, edit_ik_retargeter, edit_pose_search, edit_control_rig, and edit_enhanced_input (and sometimes picking the wrong one), there's now a single edit_rigging tool that figures out what you mean automatically.

This applies across the board — animation assets, AI trees, character assets, screenshots, and generation tools are all unified. The result: agents make fewer mistakes, pick the right tool more often, and work faster.

Agent Can See What You See

The screenshot tool is now much more powerful. By default, it auto-captures whatever viewport you're focused on — whether that's your level, a material editor, a skeletal mesh preview, or a Niagara system. The agent can also control the camera: move to a specific location, focus on an actor, orbit around an asset, or switch view modes — all to understand your scene better.

Zero-Setup Install

Everything the plugin needs to launch agents is now bundled. No more installing Node.js, running npm, or debugging PATH issues.

Claude Code and Codex adapters ship with the plugin, ready to go on Windows, Mac, and Linux
Existing manual installs are still detected and work fine

Continue Conversations Across Agents

Start a task in Claude Code, then pick it up in Codex or OpenRouter — without losing context.

Chat handoff — the plugin generates an AI summary of your conversation that the next agent can understand
Load Claude Code history — resume any past Claude Code session directly in the plugin
Kimi CLI added as a new supported agent

Environment Query System (EQS) Support

Agents can now create and edit EQS assets — add query nodes, configure tests and generators, and wire up AI perception queries through natural language.

Much More Stable

Tool execution is now wrapped in crash protection — if something goes wrong, the editor stays alive and the operation is rolled back cleanly
The plugin now validates Blueprint health after every edit, catching corruption before it causes problems later
Threading issues that could cause random crashes with MCP agents are eliminated

Other Improvements

See per-model cost breakdowns (input, output, cache, web search) in the usage display
Plugin can now update itself directly from Betide Studio, so you don't have to wait for Fab marketplace review
New Choosing an Agent guide to help you pick the right agent for your workflow
Fixed OpenRouter sessions hanging indefinitely
Fixed Copilot CLI failing to start
Fixed build errors on some configurations
Fixed markdown rendering issues in chat
