Mim is an AI-powered knowledge management system for Claude Code. It automatically captures, organizes, and validates project-specific knowledge so nothing learned is ever lost.
Knowledge is organized into categories:
- Architecture - System design decisions and structural patterns
- Patterns - Recurring code patterns and best practices
- Dependencies - Package relationships and version constraints
- Workflows - Development processes and automation
- Gotchas - Edge cases, pitfalls, and lessons learned
- Node.js 18+
Once per machine:
claude plugin marketplace add lucianHymer/mimOnce per repo:
claude plugin install mim-ai@mim-marketplace --scope projectThat's it. Mim will guide you through the rest.
Once installed, everything happens in the background:
- Automatic capture: As you work, Claude uses
remember()to capture discoveries about your codebase - Background processing: Direct file writes, no queue, instant
- Validation:
/mim:validatechecks knowledge against current codebase - Review:
/mim:reviewresolves ambiguous items interactively
The knowledge is loaded into Claude's memory through your project's CLAUDE.md file. Use /memory or /context in Claude Code to verify it's working.
/mim:validate- Check all knowledge entries against current codebase/mim:review- Resolve unresolved knowledge items interactively/mim:remember- Learn about the remember workflow
- Built on Claude Code

Norse mythology tells of Mímir, guardian of the Wellspring beneath Yggdrasil where all knowledge pools and swirls. The Vanir claimed his head. Odin claimed it back. Now preserved in herbs and rune-magic, the severed head whispers secrets from the cosmic deep - deathless, sleepless, all-remembering.
Mim captures what Claude Code discovers in its wanderings, preserving each insight in an ever-growing Wellspring of Knowledge. Nothing learned is lost. Every discovery feeds the depths.
What dies in context lives eternal in the Wellspring.
A knowledge accumulation system for Claude Code that
never forgets what it learns.
