-### Technical Insights -- **Security-first development**: Agent validation caught critical issues pre-production -- **Input validation is essential**: ZDOTDIR extraction needed sanitization -- **TOCTOU vulnerabilities**: Race conditions exist in simple scripts -- **Empty state validation**: Must validate contents, not just existence -- **Permissions matter**: Reusable workflows need explicit permission grants - -### Process Insights -- **TDD workflow**: Caught bugs early, enabled safe refactoring -- **Agent collaboration**: Multiple agents provide comprehensive coverage -- **Iterative hardening**: Implementation → validation → security fixes works well -- **Session handoff**: Clear documentation enables seamless continuation -- **Small PRs**: Breaking work into focused PRs (Issue #61, workflow fix) maintains quality -
