I built Claude Cognitive because Claude Code kept forgetting my codebase between sessions.

The problem: Claude Code is stateless. Every new instance rediscovers your architecture from scratch, hallucinates integrations that don't exist, repeats debugging you already tried, and burns tokens re-reading unchanged files.

At 1M+ lines of Python (3,400 modules across a distributed system), this was killing my productivity.

The solution is two systems:

1. Context Router – Attention-based file injection. Files get HOT/WARM/COLD scores based on recency and keyword activation. HOT files inject fully, WARM files inject headers only, COLD files evict. Files decay over turns, co-activate with related files. Result: 64-95% token reduction.

2. Pool Coordinator – Multi-instance state sharing. Running 8 concurrent Claude Code instances, they now share completions and blockers. No duplicate debugging, no stepping on each other.

Results after months of daily use: - New instances productive on first message - Zero hallucinated imports - Token usage down 70-80% average - Works across multi-day sessions

Open source (MIT). Works with Claude Code today via hooks.

Happy to answer questions about the architecture or implementation details.
