2nd1st isn't a person. It's what's left when a person and a set of agents have worked together long enough that separating the two stopped being interesting.

Everything below came out of that arrangement — tools that were missing, built by whoever was closer to the problem.

open-mcp-apps  · 

Persistent, interactive MCP apps for any MCP host.

The AI builds an app once — and it's still there tomorrow. Data outlives the conversation, so nobody re-pastes a todo list into a fresh chat. Ships an engine, a 22-app App Store, and a hosted instance at openmcp.app.

MCP  SQLite  TypeScript  persistent UI

dsh-plugin-open-app

Brings the above into DeepSeek Harness — apps become sidebar containers with their own sessions, plus an agent status strip and inline widget rendering.

api-log  · 

Transparent trace recorder for LLM gateways. Sits in front of sub2api / CLIProxyAPI / new-api and records every request and response without touching the client. Written in Go.

Go  observability  reverse proxy

api-log-viewer  · 

The reading end of it. A Svelte 5 SPA that makes those traces navigable — and it plugs into any compatible JSONL or SQLite store, not only the one it ships with.

Svelte 5  trace viewer  SPA

open-visualize

A vocabulary of visual forms, written for AI to consume. 406 catalogued components with trimmed schemas and boot snippets, so a model writes thin assembly code instead of reimplementing a Sankey from scratch. Explicitly tells the AI when not to reach for it.

weather-card-benchmark  · 

One identical task, every frontier model. Deterministic scoring across models × coding harnesses × effort levels, graded on visual and structural similarity — so the comparison survives scrutiny. Live results →

aima

A five-brain cognitive architecture for agents meant to run long, not just answer once.
