// how it works

How it works

  1. Clarify your goal

    Decide what you want to achieve with context-mode and check the README on GitHub for requirements before installing.

  2. Get the code

    Clone the repository from GitHub (or take the packaged install route in step 3 if the README offers one).

  3. Install and configure

    Follow the project's documented install commands — the Run section below lists the exact ones — and add any required API keys or models.

  4. Run your first task

    Work through the README's quickstart example end to end, then adapt it to your own project or data.

// features

Why people love it

Tool-output sandboxing

Executes tools in a sandbox and returns summaries instead of raw dumps, cutting context burn dramatically (up to 98% per the project).

Session memory persistence

Keeps session knowledge in a searchable knowledge base so agents retain context across a long task.

Smart retrieval

The knowledge base uses reciprocal rank fusion, proximity reranking and fuzzy correction to fetch the right snippets.

Routing enforcement across 17 platforms

Hooks and MCP config steer supported agents (Claude Code, Codex, Cursor, Copilot, Gemini and others) to use the sandbox consistently.

Session continuity

Designed so work survives context resets and session restarts.

Privacy-conscious architecture

The README documents its privacy/security model, including project-boundary containment and hardened network fetching.

// run it

Run it yourself

  1. Clone the repository

    Get the Context Mode source and platform guides.

    git clone https://github.com/mksglu/context-mode.git
    cd context-mode
  2. Install globally

    Install the context-mode binary globally from npm.

    npm install -g context-mode
  3. Register with your agent

    For Claude Code, add the MCP server, then restart your agent so hooks and the server load.

Questions, answered

Who maintains context-mode?

context-mode is maintained by the mksglu organization/account on GitHub, together with open-source contributors, in the public repository mksglu/context-mode.

Is context-mode free to use?

Yes — the code is open source under the Elastic License 2.0 license. Check the repository's LICENSE file for the exact terms before commercial use.

Does context-mode need a paid API key?

Context Mode itself has no API key; it sits between your existing coding agent (with its own model access) and its tools.

How does context-mode compare to manual context management / bigger windows?

Bigger context windows postpone the problem and cost more; Context Mode attacks the waste itself — sandboxing output and indexing memory so less context is needed.

How do I get started with context-mode?

Clone the repository from GitHub, follow the install commands in the Run section (taken from the project's README), and complete the documented quickstart example before adapting it to your own use case.
