Author here. I built this because I kept rebuilding the same agent personality every time I switched frameworks. Discord bot one week, Slack bot the next, Claude Code after that. Each time I'd lose everything the agent had learned.
The psychology stack came from frustration with RAG-based memory. Vector similarity treats a casual "nice weather" the same as "my mom passed away." Human memory doesn't work that way. We model significance gating (LIDA), emotional salience (Damasio), and activation decay (ACT-R) so the agent remembers what actually matters.
Quick start if you want to try it:
pip install soul-protocol
soul init "MyAgent"
soul observe "I love building open source tools"
soul recall "what do I enjoy"
soul status
The .soul file is just a ZIP. Rename it, read the JSON inside. No magic.
Happy to answer questions about the memory architecture, the eval methodology, or the spec design.
HN values things you can build with and ship. The negative sentiment isn't really about the underlying tech, it's about the ratio of speculation to actual utility.
Most crypto conversations still center around price, tokens, and "number go up." That doesn't land with a crowd that cares about solving real problems with software.
The tech underneath is interesting, though. ZKPs for privacy, programmable settlement, onchain identity. But those conversations get drowned out by the noise of yet another token launch or influencer pump.
The sentiment would shift if more projects shipped useful products first and tokenized later (or never). The crypto projects HN does respect (Signal adding MobileCoin, the ZKP work Google is doing) lead with the problem they solve, not the financial instrument they created.
