WCP Inbox: Activity Awareness for Shared Namespaces

The problem

When someone creates or assigns a work item in a shared namespace, the other person has no way to know without leaving WCP (e.g., checking Slack). The signal should stay in the system.

How it works

Every WCP user gets a persistent inbox — a stream of activity from shared namespaces and assignments
Entries get delivered automatically on your next MCP tool call. Claude sees them and says something like: "Emerson created ATLAS-26 for you and commented on ATLAS-14. Want me to pull either up?"

Building a Personal OS with Obsidian + Claude Code + Custom MCP

The Pitch

I built a "Personal Operating System" -- an Obsidian vault that serves as a unified life management system with Claude (via Claude Code CLI) as the primary interface. It covers work, career, family, personal growth, side ventures, and even recipes.

The interesting parts:

Claude is the primary interface, not Obsidian's GUI. The vault is designed to be read and written by an AI agent, with Obsidian as a secondary browsing layer.
A project-level CLAUDE.md file teaches Claude the system's full conventions, folder structure, and linking rules -- every session.

Obsidian Vault Link Index — MCP Server for Claude Code

A TypeScript MCP server that gives Claude instant graph navigation over an Obsidian vault. It parses all wiki-links, builds a SQLite index, and exposes query tools that Claude can call mid-conversation.

Why

Claude navigates an Obsidian vault badly without this. Every graph traversal is manual breadth-first search — one tool call at a time. "What files link to Kim.md?" requires a Grep across the whole vault. With this index, it's a single MCP tool call returning results in ~200 tokens instead of 4K+.

Dave's Pairing Exercise

Hello and thanks for spending some time pairing with me! This exercise is an opportunity for us to try out working together and hopefully have some fun writing code!

This exercise is open ended and collaborative. There are no set goals or evaluation metrics.
We have 60 minutes together, and as that is not a lot of time, we should spend it wisely and make sure we make the most of it.
It's best to use the candidate's (your) machine, in their most comfortable environment/IDE, while sharing screen.
It's recommended to use the language/framework you are most familiar with, and choose a task that would be best in this language/framework (it's not the day for trying a new language :) )
Bonus points if you run rails new/npm install/composer create-project/etc beforehand so that we can get started a bit faster
