From Assistant to Collaborator: How My AI Second Brain Grew Up (and more)
Hey friends, I know a Friday afternoon email is bad for ✨engagement✨ but I just remembered I haven't sent one of these out an about a month, so it's going to have to do. The roundup is still heavy on the AI stuff, I know, but I'm still very much enjoying how the PM role is changing, so I expect to be locked in (that's what we say now I think?) for a while longer.
Anyway, have good weekend, ok? -Rian

From Assistant to Collaborator: How My AI Second Brain Grew Up
The fifth post in the AI second brain series, covering the shift from "tool I invoke" to "system I dispatch." Three capabilities drove the change: multi-agent workflows that run specialist agents in parallel and synthesize their findings, a four-layer cross-session memory system (stable facts, session log, corrections, decisions), and domain skills that encode institutional knowledge about specific products and their failure modes. The post includes a concrete walkthrough of the customer escalation investigation workflow — five phases from ticket classification through blind validation — and four practical observations about the cost of maintaining it: process design over prompt writing, validation built into the workflow, the discipline of actually running /session-end, and the ongoing drift of domain skills as products change.
I am finally — FINALLY — off WordPress
After 18 years on WordPress and Dreamhost, elezea.com is now running on Astro, deployed to Cloudflare Workers, with no database and no server-side runtime. The migration that kept getting filed under "someday" only became possible after iterating on a detailed plan with Claude Code over several weeks — the plan eventually ran to 1,300 lines and covered everything from shortcode handling to DNS cutover. The actual migration took a single weekend. Search runs client-side via Pagefind, content lives as Markdown in a git repo, and the site is the fastest it's ever been. The broader point: AI is good at making vague, scary projects legible — iterating on a plan long enough turns an impossible thing into a checklist.

/tmpto avoid accidental commits, and use red/green TDD when an agent finds a bug so the fix lands in permanent automated tests.

- Evals Are the New PRD — Braintrust's argument that for AI products, the eval replaces the PRD: it defines what "good" looks like, sets the acceptance criteria, and gives engineering a clear directive: "make this number go up."
