Using Elyra
This page collects day-to-day usage details that do not fit on the quickstart page.
Interactive Mode

The interface has four main areas:
- Startup header - shortcuts, loaded context files, prompt templates, skills, and extensions
- Messages - user messages, assistant responses, tool calls, tool results, notifications, errors, and extension UI
- Editor - where you type; border color indicates the current thinking level
- Footer - working directory, session name, token/cache usage, cost, context usage, and current model
The editor can be replaced temporarily by built-in UI such as /settings or by custom extension UI.
Editor Features
| Feature | How |
|---|---|
| File reference | Type @ to fuzzy-search project files |
| Path completion | Press Tab to complete paths |
| Multi-line input | Shift+Enter, or Ctrl+Enter on Windows Terminal |
| Images | Paste with Ctrl+V, Alt+V on Windows, or drag into the terminal |
| Shell command | !command runs and sends output to the model |
| Hidden shell command | !!command runs without sending output to the model |
| External editor | Ctrl+G opens $VISUAL or $EDITOR |
See Keybindings for all shortcuts and customization.
Slash Commands
Type / in the editor to open command completion. Extensions can register custom commands, skills are available as /skill:name, and prompt templates expand via /templatename.

Message Queue
You can submit messages while the agent is still working:
- Enter queues a steering message, delivered after the current assistant turn finishes executing its tool calls.
- Alt+Enter queues a follow-up message, delivered after the agent finishes all work.
- Escape aborts and restores queued messages to the editor.
- Alt+Up retrieves queued messages back to the editor.
On Windows Terminal, Alt+Enter is fullscreen by default. Remap it as described in Terminal setup if you want elyra to receive the shortcut.
Configure delivery in Settings with steeringMode and followUpMode.
Sessions
Sessions are saved automatically to ~/.elyra/agent/sessions/, organized by working directory.
elyra -c # Continue most recent session
elyra -r # Browse and select a session
elyra --no-session # Ephemeral mode; do not save
elyra --session <path|id> # Use a specific session file or session ID
elyra --fork <path|id> # Fork a session into a new session file
Useful session commands:
/sessionshows the current session file and ID./treenavigates the in-file session tree and can summarize abandoned branches./forkcreates a new session from an earlier user message./cloneduplicates the current active branch into a new session file./compactsummarizes older messages to free context.
See Sessions and Compaction for details.
Context Files
Elyra loads AGENTS.md or CLAUDE.md at startup from:
~/.elyra/agent/AGENTS.mdfor global instructions- parent directories, walking up from the current working directory
- the current directory
Use context files for project conventions, commands, safety rules, and preferences. Disable loading with --no-context-files or -nc.
System Prompt Files
Replace the default system prompt with:
.elyra/SYSTEM.mdfor a project~/.elyra/agent/SYSTEM.mdglobally
Append to the default prompt without replacing it with APPEND_SYSTEM.md in either location.
Exporting and Sharing Sessions
Use /export [file] to write a session to HTML.
Use /share to upload a private GitHub gist with a shareable HTML link.
If you use elyra for open source work and want to publish sessions for model, prompt, tool, and evaluation research, see badlogic/pi-share-hf. It publishes sessions to Hugging Face datasets.

Design Principles
Elyra keeps the core small and pushes workflow-specific behavior into extensions, skills, prompt templates, and packages.
It intentionally does not include built-in MCP, sub-agents, permission popups, plan mode, to-dos, or background bash. You can build or install those workflows as extensions or packages, or use external tools such as containers and tmux.
For the full rationale, see the design discussion in the project documentation.
