# Preserve coding-agent context by sandboxing bulky tool output and retrieving only relevant session state with Context Mode

Use Context Mode when a coding agent keeps burning context on large tool outputs or loses its place after compaction. It wraps tool-heavy workflows with sandboxed execution, indexed session history, and targeted retrieval so the agent can keep working without reloading raw data into the prompt.

## Prerequisites

Supported coding agent runtime with MCP or plugin support; Node.js; local SQLite storage

## Installation

Choose whichever fits your setup:

1. Copy this skill folder into your local skills directory.
2. Clone the repo and symlink or copy the skill into your agent workspace.
3. Add the repo as a git submodule if you manage shared skills centrally.
4. Install it through your internal provisioning or packaging workflow.
5. Download the folder directly from GitHub and place it in your skills collection.

Install command or upstream instructions:

```
Install via the platform-specific instructions in the upstream docs. Examples include `npm install -g context-mode`, `claude mcp add context-mode -- npx -y context-mode`, or the Claude Code marketplace/plugin install flow.
```
