Context Intelligence Layer for all Coding Agents

What is Context Intelligence Layer for all Coding Agents?

A local-first context runtime for AI coding agents that compresses file reads and shell output before they reach the LLM, reducing token waste by 60–95% (up to 99% on cached reads). It integrates with any MCP-compatible client across 30+ IDEs and AI tools via a single Rust binary with shell hook and 60+ tools.

How to use Context Intelligence Layer for all Coding Agents?

Install via one of curl -fsSL https://leanctx.com/install.sh | sh, brew install lean-ctx, npm install -g lean-ctx-bin, or cargo install lean-ctx. Run lean-ctx setup to auto-detect your AI tools, then lean-ctx doctor to verify. After setup, restart your shell and editor to activate the MCP server and shell hooks.

Key features of Context Intelligence Layer for all Coding Agents

• Cached, mode-aware file reads (full, map, signatures, diff, …)
• Shell output compression via 95+ patterns (git, npm, cargo, docker, …)
• Multi-edge Property Graph with weighted impact analysis and hybrid search
• PR Context Packs via lean-ctx pack --pr
• Portable context packages (.lctxpkg) with SHA-256 integrity
• Session memory (CCP) persisting task facts across chats
• Streamable HTTP MCP mode (lean-ctx serve)
• Opt-in telemetry; local-first by default

Use cases of Context Intelligence Layer for all Coding Agents

• Daily AI coding sessions with shell-heavy workflows (git, tests, builds)
• Medium-to-large repos or monorepos where context quickly grows expensive
• Multi-agent or team projects needing shared, portable context packages
• Reducing token costs in paid LLM usage during long coding sessions
• Local-first development where data must never leave the machine

FAQ from Context Intelligence Layer for all Coding Agents

What dependencies or runtime does it require?

A single Rust binary with no runtime dependencies. The universal install script does not require Rust to be installed. Package managers (brew, npm, cargo) can be used instead.

Is telemetry collected or is my data sent anywhere?

No telemetry by default. All processing runs locally; your code never leaves your machine unless you explicitly enable optional anonymous stats sharing during setup.

Which AI coding tools and IDEs are supported?

30+ agents with first-class auto-setup including Cursor, Claude Code, GitHub Copilot, Windsurf, Codex, Gemini CLI, Aider, Cline, JetBrains IDEs, VS Code, Zed, Neovim, Emacs, and more. Any MCP-compatible client works out of the box.

Can I disable the shell hook per session or per command?

Yes. Run lean-ctx-off to disable for the current shell session. Use lean-ctx -c --raw "git status" to run a single command uncompressed.

How can I verify installation and diagnose issues?

Run lean-ctx doctor for a health check, or lean-ctx doctor --json for a shareable diagnostic report.
