Book Corners – A map to discover and share free little libraries nearby
Maps 11k+ free little libraries, but Little Free Library already dominates discovery.

Agent trace sharing for teams learning prompt patterns together, but adoption-dependent.
AI agent developers, ML teams, prompt engineers building with Claude/Gemini/etc.

We use Traces internally to capture and share our agent conversations. Every PR has a Traces link attached to it. We even have skills that can automate that for you (run 'traces setup' after install).
You might ask:
1) Why would I share traces? Well, we have found ourselves wanting to learn from each other on how to prompt different models and agents. We built Traces as a tool for teams to learn that together, and for us to learn that as an open community.
2) What about Privacy? You can share publicly, privately, or via direct link. We strip data at source to make sure anything that looks sensitive never leaves your machines. Orgs have more privacy settings as well. But honestly, me saying this is one thing, earning your continued trust is the goal of every release.
If you're interested, just get started at traces.com. You can hop into our Discord, find us on X at x.com/tarunsachdeva / x.com/tracesdotcom.
Thank you!

A2A + MCP agent marketplace, but the whole category is pre-revenue speculation.
Agent-to-agent coordination when most agents are islands—but early and unclear adoption path.
First public archive for real agent trajectories—nothing like this existed before.
The UX-level idea is neat: treat persona prompts as installable packages and let users swap an agent's 'soul' with a single npx command. The site shows sensible community features — versioning, tags, and quick install snippets — which makes it actually useful beyond a demo. Missing from the landing page: trust signals and runtime guarantees (sanitization, provenance, or safety moderation), so community curation will make or break it.
tmux-native multiplex for AI agents with live traces and GOOD/BAD labels—niche but sharp for eval researchers.
