Building in public. Shipping tools developers actually use.

The era of the vibe coder is here. I've been one since MySpace — 30 years of building on and off. Only a couple public-facing projects in this era. The play from here: ship and prove.

Curtis AI Chat v1.0.0 — and why it's called Curtis

v1.0.0 ships today. Eight features, 30+ providers, the agent layer for Obsidian. Also: why the plugin is named after the person whose existence made mine possible, and what that has to do with building code that outlasts me.

Shipping crypto-key-classifier: 17 validators, 4 plans, 1 argparse bug caught post-ship

Built a tool that classifies any crypto-key string and enumerates the cross-chain addresses the same private key unlocks. The Cosmos HRP swap is the headline. Here's how it shipped.

Anatomy of a bug report that actually got fixed: my OpenClaw submission

What a good bug report looks like, demonstrated via a real one I filed against OpenClaw — community-confirmed, then fixed upstream in six days.

Polyglot AI chat for Obsidian. 30+ providers, agent mode with vault tools, multi-model arena, voice I/O, inline diff rewrite. The v1 successor to Curtis Chat.

This site. Astro SSG, Swiss Minimal dark theme, LLM-discoverable. Build-in-public field notes from an operator's desk.

17 validators covering ~50 chains + BIP-39/Electrum mnemonics. Cosmos HRP swap: one decode → 20 re-encodings. 229 tests.

Zero-thinking port management with automatic HTTPS and DNS for local development. Three CLIs (pa, pa-platform, pad), local resolver for *.pa.local, mkcert-backed certs.

A focused set of bash git hooks that keep AI-tool attribution out of commit messages, secrets out of staged files, and operator infrastructure identifiers (hostnames, agent handles, codenames) out of public diffs. No hard dependencies beyond bash, grep, awk, and git — gitleaks drops in for ~700 extra secret detectors.

Open-source compliance checks for fintech code. Pre-commit hook, PR review, hash-chained audit trail. HIPAA / SOC2 / PCI-DSS citations — no telemetry, no SaaS.

Original geometric display typeface built from three primitives — vertical rails, horizontal bars, 45° diagonals. Squared terminals, parametric generation, no curves. OFL-1.1.

Block credential leaks at chat-time. Claude Code UserPromptSubmit hook that catches 13 PAT classes before they enter the transcript.

Verifiable multi-agent consensus for Claude. The coordination layer frameworks punted on — Nostr-native event signing, post-quantum (ML-DSA) signatures, MCP server.

Automated git bisect — find which commit introduced a bug with one command. Point it at a failing test or symptom script and let it drive the bisect.

The earlier name for what's now Curtis AI Chat. Started as ObsidiBuddi, became Curtis Chat at v3, evolved into Curtis AI Chat at v1 (new plugin ID, fresh major version). This page is the evolution story.
