Skilletlean-ctx
MCP server and context runtime for AI coding agents: session caching, AST-aware compression, and 90+ shell patterns to reduce token usage. Supports Claude Code, Cursor, Copilot, and other integrations. Install the Claude Code skill with `lean-ctx init --agent claude-code`; docs at [leanctx.com](https://leanctx.com).
What it is
lean-ctx is a development & code tools skill for AI coding agents. Open-source community skill. Skills are small, focused packages of instructions and tools that an agent loads on demand, so it gains this capability only when the task calls for it, keeping its context lean the rest of the time.
When to use it
Reach for lean-ctx whenever your task falls under development & code tools. Because it ships as a portable skill, it works across Claude Code, Cursor, Codex and any agent that reads the SKILL.md format.
How to install
Clone or download the skill folder into your agent's skills directory (for Claude Code: `~/.claude/skills/<name>`). Most skills include a `SKILL.md` that the agent reads on demand. See the source link for exact setup.
