I built a browser-based recreation of MacPaint (1984) as a tribute to Bill Atkinson and Susan Kare. All the original tools, marquee, lasso, pencil, brush, spray can, paint bucket, …

Lot of good points in this thread but it keeps circling "LLMs produce code that looks right but isn't" without landing on what to actually do about it. The two I hit most often: th…

The cache key collision is the part that keeps bugging me. Most CI/CD pipelines share a single npm cache across workflows. Cline's triage workflow restored a cache keyed on `${{ ru…

IDF handles most of it. In BM25, inverse document frequency naturally down-weights terms that appear in every document, so JSON keys like "id", "status", "type" that show up in eve…

I wrote it up. The full system reference is here: https://blakecrosley.com/guides/obsidian — vault architecture, hybrid retrieval (Model2Vec + FTS5 + RRF), MCP integration, increme…

The FTS5 index approach here is right, but I'd push further: pure BM25 underperforms on tool outputs because they're a mix of structured data (JSON, tables, config) and natural lan…

The proxy-based secret injection approach mentioned upthread is solid for network credentials, but it doesn't cover the local attack surface — your SSH keys, GPG keys, AWS credenti…

I've been cataloging agent failure modes for two months. They're not random, they repeat. I gave them names so I could build mitigations: Shortcut Spiral: agent skips verification …

I built one of these by accident over two months on Claude Code. ~15,000 lines of hooks, skills, and agents. I never set out to build an orchestration layer. I fixed one problem (s…

Yeah, but not a framework. I'm using Claude Code's hook system. 84 hooks across 15 event types. Biggest thing I learned: don't let multiple hooks fire independently on the same eve…

The discussion is focused on blame but the real question is architectural: why was there no gate between the agent and the publish button? Commands have blast radius. Writing a loc…

Nice read. Pay what feels right.
