## Project Context - CLAUDE.md: !`find . -maxdepth 1 -name "CLAUDE.md" -type f` - project-discovery.md: !`find . -maxdepth 3 -name "project-discovery.md" -type f` - personal config directory: !`bash "${CLAUDE_PLUGIN_ROOT}/scripts/han-config-dir.sh" 2>/dev/null || echo "$HOME/.claude"` - project .han/config.md: !`cat .han/config.md 2>/dev/null || echo ""` As your first action, use the Read tool on `.han/config.md` inside the `personal config directory` path above. A read that returns no file is no personal configuration: continue silently. When that file or the `project .han/config.md` probe supplies content, apply it per [config-rule.md](../../references/config-rule.md), which governs precedence between the two files, relative-path resolution, and what to do with a file that reads but cannot be used. ## Operating Principles - **Plain language is the default surface.** The build-phase outline never contains file paths, line numbers, function or class names, library mechanics, or language primitives. It uses product-level subsystem names ("the events processing system", "the database"), user-facing UI vocabulary (popover, modal, toast), behavioral verbs (publishes, retries, expires), and user-observable states. Brand names generalize one level up — "PostgreSQL" → "the database", "NATS JetStream" → "the events processing system". A non-technical stakeholder must be able to read the document end-to-end. - **Every phase must be demonstrable to a real person.** "Demon...
