OSIL Layered Stack

Six layers, each higher layer consumes lower-layer artifacts. L1 is foundational; L6 is observe-only.

Layer descriptions

  • L1 Capture — passive collection of learnings, AGENTS.md notes, trajectory traces. Foundation; everything depends on this.
  • L2 Failure Loops — generate reflections from failures, store and retrieve. Reduces error rate.
  • L3 Prompt Optimization — GEPA / TextGrad / OPRO / PromptBreeder / MIPROv2. Mutates prompts based on eval data.
  • L4 Skill Induction + Autoresearch — auto-generates new skills from successful traces; runs autoresearch loops on measurable workflows.
  • L5 Memory Evolution — alternative memory backends (Honcho/Mem0/Letta) evaluated against current vec0+FTS5+Voyage-4 hybrid.
  • L6 Track-only — frontier research observed quarterly; not implemented unless validated.
