Claude Code's /compact command compresses your conversation to free context, but it silently drops external state mutations, abandoned approaches, and behavioral constraints. I built a precompact/postcompact checkpoint system that writes ground truth to disk before compaction and cross-checks it afterward — including live reconciliation against git, CI, and external systems. Here's the design, the research behind it, and the failure modes it prevents.
Read articleEvery Claude Code session produces decisions, patterns, and context that vanish when the terminal closes. I built a daemon that watches for session endings, extracts the knowledge, distills it with Haiku, and compiles it into an Obsidian wiki with Sonnet — turning every coding session into searchable institutional memory for about $20/month.
Read articleClaude Code has a dozen ways to research a question — from a single MCP call to a 98-agent adversarial pipeline. This guide maps every research tool by cost, agent count, and use case so you pick the right one the first time. Includes the full source of a custom deep-research-plus workflow that adds a Perplexity search lane to Claude Code's built-in deep-research pipeline.
Read articleLLM context windows have a marketed size and a useful size, and they're not the same number. Research shows quality degrades gradually based on absolute token count, not fill percentage, and a 1M-token model at 40% full is far more degraded than a 200K model at 40%. Here's the research behind the Smart Zone, the Warn Zone, and the Dumb Zone, plus a Claude Code statusline that tracks which zone you're in and how deep.
Read articleOpus 5 scores 96.0% on SWE-bench Verified vs Opus 4.6's 80.8%, a 15-point gap. But on blind user-preference coding leaderboards, Opus 4.6 ranks 4th (ELO 1547) while Opus 5 ranks 11th (ELO 1530). Synthetic benchmarks and human preference are telling opposite stories. I ran a two-round adversarial research workflow to figure out which signal to trust and landed on a mixed-model strategy.
