Context Management	Compact, merge, and transfer conversation context between sessions and agents.	layers

Tab Menu

Hover over any tab with an established session to access the tab menu overlay:

Action	Description
Copy Session ID	Copy the session ID to clipboard (for session continuity)
Star Session	Bookmark this session for quick access
Rename Tab	Give the tab a descriptive name
Mark as Unread	Add unread indicator to the tab
Context: Copy to Clipboard	Copy the full conversation to clipboard
Context: Compact	Compress context while preserving key information
Context: Merge Into	Merge this context into another session
Context: Send to Agent	Transfer context to a different agent

Tab Close Operations

The tab menu also provides bulk close operations for managing multiple tabs:

Action	Description
Close	Close the current tab
Close Others	Close all tabs except this one
Close Tabs to the Left	Close all tabs to the left of this one
Close Tabs to the Right	Close all tabs to the right of this one

These operations respect the Unread Filter: when the filter is active, only visible tabs are affected — hidden "read" tabs are preserved.

Position-aware options: The menu intelligently hides inapplicable options:

• First tab: "Close Tabs to the Left" is disabled
• Last tab: "Close Tabs to the Right" is disabled
• Single tab: "Close" and "Close Others" are disabled

All close operations support undo — press Cmd+Shift+T / Ctrl+Shift+T to reopen recently closed tabs (up to 25 tabs are remembered).

These actions are also available via Quick Actions (Cmd+K / Ctrl+K) with keyboard shortcuts displayed:

Tab Export

Export any tab conversation as a self-contained HTML file:

1. Right-click the tab → Context: Copy to Clipboard
2. Or use Command Palette (Cmd+K / Ctrl+K) → "Export tab to HTML"

The exported HTML file includes:

• Full conversation history with all messages
• Your current theme colors — the export adopts your active Maestro theme
• Maestro branding with links to the website and GitHub
• Session metadata — agent type, working directory, timestamps, token usage
• Rendered markdown — code blocks, tables, and formatting preserved

This is useful for sharing conversations, creating documentation, or archiving important sessions.

Context management lets you combine or transfer conversation history between sessions and agents, enabling powerful workflows where you can:

• Compact & continue — Compress your context to stay within token limits while preserving key information
• Merge sessions — Combine context from multiple conversations into one
• Transfer to other agents — Send your context to a different AI agent (e.g., Claude Code → Codex)

Context Window Warnings

As your conversation grows, Maestro monitors context window usage and displays warnings when you're approaching limits.

The warning banner appears below the input box showing:

• Current context usage percentage
• Compact & Continue button for one-click context compression

Why Context Usage Matters

Operating near context limits degrades AI performance. When context reaches ~80% capacity or higher:

• The AI loses access to earlier parts of your conversation
• Important decisions, code changes, and context get pushed out
• Response quality drops as the model struggles to maintain coherence
• You may experience more hallucinations and forgotten instructions

For best results, compact your context before reaching 60-70% usage — don't wait for the red warning.

Configuring Warnings

Customize warning thresholds in Settings (Cmd+, / Ctrl+,) → General → Context Window Warnings:

Setting	Default	Description
Show context consumption warnings	Enabled	Toggle warning banners on/off
Yellow warning threshold	60%	Early warning — good time to consider compacting
Red warning threshold	80%	Critical — compact immediately to avoid degradation

Recommended thresholds:

• Set yellow to 50-60% if you prefer earlier warnings
• Set red to 70-80% — going higher risks quality degradation
• Lower both thresholds if you frequently work on complex tasks that require the AI to remember many details

Compact & Continue

When your conversation approaches context limits, you can compress it while preserving essential information:

1. Right-click a tab → "Context: Compact", or use Command Palette (Cmd+K / Ctrl+K) → "Context: Compact"
2. The AI compacts the conversation, extracting key decisions, code changes, and context
3. A new tab opens with the compressed context, ready to continue working

When to use:

• The context warning sash appears (yellow at 60%, red at 80% usage)
• You want to continue a long conversation without losing important context
• You need to free up context space for new tasks

What gets preserved:

• Key decisions and their rationale
• Code changes and file modifications
• Important technical details and constraints
• Current task state and next steps

Merging Sessions

Combine context from multiple sessions or tabs into one:

1. Right-click a tab → "Context: Merge Into", or use Command Palette (Cmd+K / Ctrl+K) → "Merge with another session"
2. Search for or select the target session/tab from the modal
3. Review the merge preview showing estimated token count
4. Optionally enable Clean context to remove duplicates and reduce size
5. Click "Merge Into"

The modal shows:

• Paste ID tab — Enter a specific session ID directly
• Open Tabs tab — Browse all open tabs across all agents
• Token estimate — Shows source size and estimated size after cleaning
• Agent grouping — Tabs organized by agent with tab counts

The merged context creates a new tab in the target session with conversation history from both sources. Use this to consolidate related conversations or bring context from an older session into a current one.

What gets merged:

• Full conversation history (user messages and AI responses)
• Token estimates are shown before merge to help you stay within context limits

Tips:

• You can merge tabs within the same session or across different sessions
• Large merges (100k+ tokens) will show a warning but still proceed
• Self-merge (same tab to itself) is prevented
• Enable "Clean context" for large merges to reduce token count

Sending to Another Agent

Transfer your context to a different AI agent:

1. Right-click a tab → "Context: Send to Agent", or use Command Palette (Cmd+K / Ctrl+K) → "Send to another agent"
2. Search for or select the target agent from the list
3. Review the token estimate and cleaning options
4. Click "Send to Session"

The modal shows:

• Searchable agent list with status indicators (Idle, Busy, etc.)
• Agent paths to distinguish between agents with similar names
• Token estimate — Shows source size and estimated size after cleaning
• Clean context option — Remove duplicates and reduce size before transfer

Context Cleaning: When transferring between agents, the context can be automatically cleaned to:

• Remove duplicate messages and verbose output
• Condense while preserving key information
• Optimize token usage for the target session

Cleaning is enabled by default but can be disabled for verbatim transfers.

Use Cases:

• Start a task in Claude Code, then hand off to Codex for a different perspective
• Transfer a debugging session to an agent with different tool access
• Move context to an agent pointing at a different project directory
• Share context with a worktree sub-agent working on the same codebase
