Show HN: Persistent Mind Model (PMM) – Update: an model-agnostic "mind-layer"
Since then, I’ve added some big updates:
- DevTaskManager — PMM can now autonomously open, track, and close its own development tasks, with event-logged lifecycle (task_created, task_progress, task_closed).
- BehaviorEngine hook — scans replies for artifacts (e.g. Done: lines, PR links, file references) and uto-generates evidence events; commitments now close with confidence thresholds instead of vibes.
- Autonomy probes — new API endpoints (/autonomy/tasks, /autonomy/status) expose live metrics: open tasks, commitment close rates, reflection contract pass-rate, drift signals.
- Slow-burn evolution — identity and personality traits evolve steadily through reflections and “drift,” rather than resetting each session.
Why this matters: Most agent frameworks feel impressive for a single run but collapse without continuity. PMM is different: it keeps an append-only event chain (SQLite hash-chained), a JSON self-model, and evidence-gated commitments. That means it can persist identity and behavior across LLMs — swap OpenAI for a local Ollama model and the “mind” stays intact.
In simple terms: PMM is an AI that remembers, stays consistent, and slowly develops a self-referential identity over time.
Right now the evolution of it "identity" is slow, for stability and testing reasons, but it works.
I’d love feedback on:
What you’d want from an “AI mind-layer” like this.
Whether the probes (metrics, pass-rate, evidence ratio) surface the right signals.
How you’d imagine using something like this (personal assistant, embodied agent, research tool?).
