Founder @fiberplane; agent-native issue management. Investor in teams solving hard problems @nphardvc.














We've been running Claude Code autonomously on our codebase for months. The trick: enforcement that prevents errors from compounding across commits. - fp issue tracking with lifecycle hooks - @EffectTS_ traces - Drift-anchored QA scenarios - Commit discipline before context compaction How we built guardrails for agentic development fiberplane.com/blog/2026-04-3…




Turns out the dark software factory runs on markdown. CLAUDE.md, specs, plans, REFACTOR-V2-BRAINSTORM.md. Agents read them as context and write more of them as output. When those docs drift from code, agents propagate the rot. Drift is the integrity layer.
