  • Session condensing showing only key moments and code
  • Team rules reviewed like pull requests before reaching agents
  • Team memory persisting when members leave
  • Session attribution on pull requests showing which commits came from sessions
  • MCP server for agents to search and learn from shared sessions
  • 4.1µs C-ABI latency native Rust Sub-Cortex execution
  • Zero dirty diffs with strict AST grammar validation and dry-run verification
  • Support for 6 production languages: Python, Rust, TypeScript/JavaScript, Go, C/C++, and Java
  • Polyglot language engines with direct Tree-sitter CST surgery
  • Machine-to-Machine sub-cortex infrastructure for autonomous agents
  • Zero Code Retention policy with ephemeral in-memory processing
  • 91.3% AST token pruning for repository context efficiency
  • Multi-file repository context with automated test-runner verification
  • Automated 5-Whys Root Cause Analysis and SRE incident diagnostics
  • System-wide dependency mapping and security audit capabilities
What makes it different
  • Real sessions only, no fabricated runs, showing actual agent failures and interventions
  • Secrets redacted on your machine before any data leaves, with server-side verification
  • Open source MIT plugin with full control over your data
  • Works with five different coding agents from one plugin
  • Team data stays on your own PostgreSQL server if you choose
  • Eliminates 95% of LLM token overhead through deterministic compiler verification instead of probabilistic inference loops
  • Operates locally with strict Zero Code Retention policy—no code logging, storage, or model training usage
  • Sub-microsecond repairs in CPU L1 cache without garbage collection pauses via native Rust FFI
  • Engineered as M2M sub-cortex infrastructure for autonomous agents, not consumer chatbot utility
