Signal Core

Signal Core is Pytxo's context arbitrage layer. The goal: send agents structural skeletons of code (signatures, types, imports) instead of full file dumps — targeting up to ~60% lower input tokens on large repos.

Today​

  • signal_core = true in pytxo.toml materializes scaffolded context for task paths
  • signal_fidelity (low | medium | high) controls how much structure is included per task or globally

Roadmap​

  • tree-sitter AST extraction on file read
  • Checkpoint compression protocol for long sessions

Configuration​

signal_core = true
signal_fidelity = "low"   # default; per-task override in [[task]]

Signal fidelity is a context tier, separate from permission tiers.
