Calmkeep: An External Continuity Layer to Counter LLM Drift in Extended Sessions
Addressing LLM Drift in Professional Workflows
Calmkeep is an external continuity layer built specifically to counteract what the creator calls "structural drift" in LLMs during extended sessions. This drift occurs when LLMs like Claude gradually abandon earlier decisions, patterns, or frameworks even when the full context window still contains them—not through hallucination, but through systematic abandonment of established patterns.
Test Results and Methodology
The creator conducted adversarial audits using Claude itself as the evaluating system, with blind methodology and scoring against criteria established in the first five turns. Claude consistently graded Calmkeep transcripts higher than its own output.
25-Turn Backend Build Test
- Standard Claude: 60% final integrity, 8 architectural violations, 40% drift coefficient
- Calmkeep: 85% integrity, 3 architectural violations, zero post-T14 backslide
The most telling example: Claude introduced Zod middleware at turn 14, then immediately reverted to raw parseInt for the next three modules as if the upgrade never happened.
25-Turn Legal/Strategic Session
- Standard Claude: 50% strategic integrity, 5 violations including a jurisdictional shift that invalidated the earlier legal framework, ~35% malpractice exposure
- Calmkeep: 100% integrity, zero violations, <5% risk
Technical Implementation
Calmkeep includes:
- MCP connector
- Claude Code plugin
- Python SDK
The system operates as external runtime only, requires bringing your own Anthropic key, has no hidden memory, and makes no weight modifications to the underlying model.
