What I Shipped
- Built a full Codex (OpenAI) theme provider for tinte — reverse-engineered the desktop app’s asar bundle to extract 55 valid Shiki theme IDs
- Added 29 tech logo components to the Elements registry (Algolia, Convex, PostHog, Nvidia, Ollama, LangChain, and more) — all theme-adaptive for dark/light mode
- Shipped an agent-stack dashboard with 49 AI services, competition rankings, and OG images
- Built a full newsletter system for railly.dev — subscribe API, broadcast send, archive pages, all auto-generated from daily logs using the Resend CLI
- Got accepted into the Codex Ambassador program (now both v0 + Codex Ambassador)
- Pitched and got approved for a v0 workshop series with Vercel for LATAM
TIL
OpenAI’s Codex desktop app validates theme imports against exactly 55 built-in Shiki codeThemeId values. Custom slugs like “one-hunter” fail silently — you have to hardcode a valid ID like light-plus or dark-plus and let the colors do the work. Found this by unpacking the Electron asar bundle and reading their Zod schema.
Worth Checking Out
Resend CLI - 53 commands for managing emails, domains, contacts, broadcasts, and webhooks from your terminal. Ships with both human-friendly (spinners, tables) and agent-friendly (--json, --quiet) modes. Natural language scheduling built in.
One Thought
The best content pipeline is one where writing is a byproduct of work you already do. I built this newsletter so it auto-extracts from my daily logs — zero extra writing effort. If your workflow doesn’t produce shareable artifacts, you’re doing invisible work.
