What is context folding in Claude Code?

Context folding is a workflow pattern that creates temporary, isolated branches for complex sub-tasks. This allows the AI to perform deep work without exceeding the token limit of the main conversation.

What happens when a branch finishes?

The branch performs a 'return' operation, which provides a concise summary and any relevant structured data back to the main context before cleaning up the intermediate verbose data.

How does budget allocation work for branches?

Budgets are assigned based on task complexity: Simple tasks get 4,096 tokens, Standard tasks get 8,192, and Complex investigations get 16,384, with automatic warnings as limits approach.

Can I run multiple branches at once?

Yes, the skill supports parallel branch coordination and can track dependencies between different sub-tasks for sophisticated agent orchestration.

Does this skill require external tools?

Yes, context folding integrates with the contextd MCP tools (branch_create, branch_return, branch_status) to manage the underlying context hierarchy.

生产力与工作流

Optimizes AI token usage by isolating complex sub-tasks into branches with dedicated budgets and automatic context cleanup.

关于

Context Folding is a specialized management skill for Claude Code designed to prevent context bloat during intricate development sessions. By leveraging the contextd MCP, it enables the creation of isolated execution branches for exploratory work, multi-file investigations, and parallel sub-tasks. Each branch operates under a defined token budget and provides structured summaries upon return, ensuring your main conversation remains clean and performant while maintaining full observability over nested task hierarchies.

主要功能

Adaptive Budgeting: Assigns token limits based on task complexity tiers (Simple, Standard, Complex).
Automated Cleanup: Clears intermediate steps and returns high-level summaries to the parent context.
0 GitHub stars
Context Isolation: Prevents global context overflow by sandboxing sub-task data.
Real-Time Monitoring: Tracks budget usage percentages with proactive warnings for exit strategies.
Dependency Orchestration: Supports parallel branch execution and structured data propagation between tasks.

使用场景

Executing exploratory refactoring that requires verbose intermediate tool outputs.
Investigating complex bugs across multiple files without polluting the main session history.
Coordinating parallel sub-agents for synthetic tasks like security reviews or documentation audits.
