Cognitive Efficiency Protocol (CEP v1)

Major release introducing CEP — a holistic approach to LLM communication optimization.

New Features

  • CEP Compliance Scoring in ctx_metrics — tracks Cache utilization, Mode diversity, Compression rate, and overall CEP Score (0-100)
  • Adaptive Instructions Engine — classifies task complexity (Mechanical / Standard / Architectural) and dynamically adjusts LLM reasoning guidance
  • Smart Context Prefill Hints in ctx_context — suggests optimal read modes for large/infrequently-used files
  • Quality Scorer — measures AST, identifier, and line preservation (>95% target)
  • Auto-Validation Pipeline — syntax checks for Rust, JS/TS, Python, JSON, TOML after file changes
  • MCP Live Stats (~/.lean-ctx/mcp-live.json) — real-time CEP metrics for dashboard integration
  • Dashboard CEP Intelligence Card — shows CEP Score, Cache Hit Rate, Mode Diversity, Compression, Task Complexity
  • TOON-Inspired Output Format — ~15% fewer tokens per header
  • Extended Filler Detection v2 — 60+ patterns across Hedging, Meta-Commentary, Closings, Transitions, Acknowledgments
  • Dynamic MAP Threshold — ROI-based identifier registration
  • Formal Action Vocabulary (TDD v2) — Unicode symbols for code changes (⊕⊖∆→⇒✓✗⚠)

Bug Fixes

  • --global --agent no longer overwrites project-local files (CLAUDE.md, .cursor/rules, etc.)
  • Multiple --agent flags now process all agents (--agent claude --agent codex)
  • Fixed shell alias recursion in doctor.rs
