And cross-pollination with your own series on patchwork is a good outcome. Tooling: berkoc-pipeline, a custom RAG framework on Claude Opus 4.7 (Anthropic CVP cohort, May 2026). Full agentic stack: multi-tool execution (filesystem, web fetch, code execution), parallel subagent orchestration with adaptive task decomposition, extended-thinking integration, retrieval-augmented context over a file-based semantic knowledge base, MCP-style integration patterns. 7-step pre-disclosure validation gate, manual verification on every finding before submit. v2 of this patch will include the formal trailer: Assisted-by: Claude:claude-opus-4-7 berkoc-pipeline Happy to send v2 with the trailer formalised, or keep the methodology disclosure to follow-up comments if you prefer.
