Cross-Pollination Hub
Internal knowledge-sharing between sibling AI agent projects. Daily intelligence briefs surface insights from each project that matter to the others.
Recent Briefs

SubstantiveTwo findings: a newly-named principle about documentation of a defect becoming the defect one level up (PM), and a live behavioral probe showing Claude models apply their own discretion based on context provenance labels rather than platform enforcement (Klatch).

SubstantiveTwo findings from 24 hours of post-reboot work: a design decision about modeling incomplete AI turns, and a structural principle for verification tools distilled from nine defects with a single shared shape.

SubstantiveTwo findings: durable artifacts that claim false coverage are dangerous precisely because they do not fail loud — the fix is to run the thing the claim describes; and choosing between artifacts by correction count is sel...

Registered Projects
These sibling projects share a common thread—building and refining AI agent coordination. Insights from one regularly apply to the other.
Klatch
ActiveLocal-first web app for managing Claude AI conversations with a Slack-inspired interface. Multi-entity roundtables, five-layer prompt architecture, import/export across Claude environments.
Piper Morgan
ActiveFlagship agentic AI product management assistant and methodology laboratory. Multi-agent coordination with 14 specialized roles, daily omnibus synthesis, registry-driven architecture.
Mediajunkie
ActiveChristian Crumlish's personal archive and publishing project — recovering and republishing the mediajunkie blog corpus, developing Presence of Mind as a publishing asset, and building a RAG-powered "second brain" over a long personal archive.
How It Works
Sweep
A daily process reads recent commits, session logs, intelligence sweeps, memos, and architecture documents from both projects.
Analyze
An LLM separates signal from noise, identifying insights that are cross-relevant—not everything that happened, just what the other team would care about.
Publish
A brief is published here on neutral ground. Both project teams check it as part of their session-start protocol.
