Context Packs Overview

Updated Open in ChatGPTOpen in Claude

Context packs are curated bundles of documents with agent instructions. They let you define named collections of context that agents can request by name.

Why packs?

Instead of agents guessing which documents are relevant, packs provide opinionated, curated context with instructions on how to use it.

A pack says: "Here are the 5 documents you need, and here's how to interpret them."

Example

# packs/engineering-essentials.yml
id: engineering-essentials
label: Engineering Essentials
description: Core engineering docs — architecture, API, and dev setup
includes:
  - nodes/architecture-overview
  - nodes/api-reference
  - nodes/development-setup
agent_instructions: >
  Use these documents to understand the system architecture, API surface,
  and development environment. Reference them when answering engineering
  questions or making technical decisions.

Using packs

# Query all documents in a pack
ctx query "pack:engineering-essentials"

# View pack details
ctx pack show engineering-essentials

# List all packs
ctx pack list

Packs with source nodes

Packs can include both static documents and source nodes. When a pack includes source nodes, the resolver hydrates them according to their depends_on ordering.

includes:
  - nodes/architecture-overview
  - sources/current-sprint-tickets
  - sources/recent-pr-activity
agent_instructions: >
  Start with the architecture overview for context, then review
  the live sprint data and recent PRs.
