# Lean Agents

Lightweight subagent replacements for Claude Code users with many MCP servers configured.

## Problem

When you have 10+ MCP servers configured (Supabase, PostHog, Playwright, GitHub, Slack, etc.), built-in subagents (Explore, Plan, general-purpose) fail with **"prompt is too long"** because they inherit all MCP tool schemas from the parent session. With 300+ tools, the schemas alone can exceed Sonnet's 200k context limit before the agent even starts.

See: [#37793](https://github.com/anthropics/claude-code/issues/37793), [#31623](https://github.com/anthropics/claude-code/issues/31623)

## Solution

This plugin provides lightweight agent replacements that use explicit `tools:` allowlists to try to reduce or avoid inheriting MCP tool schemas. This is a runtime-dependent workaround rather than a guaranteed fix (see [Limitations](#limitations)):
