SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Long agent sessions fill the context window with verbose outputs, repeated file reads, and raw payloads, degrading reasoning quality and halting progress before the task completes. ## Core Features & Use Cases - Payload Isolation: Routes verbose outputs, screenshots, and large documents to subagents so the main thread receives only summaries. - Selective Reading: Skips files irrelevant to the current task instead of consuming tokens on unused content. - Scope Budgeting: Caps files per phase, sets turn budgets, and accounts for mechanism costs when planning fan-out work. - Use Case: When an agent must analyze a large repository, apply this principle to delegate per-directory analysis to subagents and keep only condensed findings in the main conversation. ## Quick Start Apply the principle-guard-the-context-window workflow to plan this task so large outputs go to subagents and only summaries stay in the main thread.

FAQPage Schema
How do I prevent context window overflow in long agent sessions?▼

Route verbose outputs, screenshots, and large documents to subagents so the main context receives only summaries. Read files selectively based on relevance and cap the number of files processed per phase.

When should I use subagents instead of reading files directly?▼

Use subagents whenever a task produces large raw payloads that the main thread does not need in full, such as bulk file analysis or fan-out searches. The main thread should keep summaries, not raw data.

Should templates and references live in the skill file or separate files?▼

Content used on every invocation belongs inline in the skill file, since separate files cost an extra read each time. Only infrequently needed material should be externalized.

Why does reasoning quality degrade when context fills up?▼

Context overflow creates compression artifacts and can halt progress mid-session. Unlike compute or time, tokens spent inside a session cannot be reclaimed, so every token must earn its place.

What are the limits of context window management techniques?▼

These techniques reduce consumption but cannot expand the fixed window. Tasks with inherently large irreducible context, such as comparing many full documents simultaneously, may still exceed capacity and need session splitting.
