RAG for Inboxes: Grounding Email Replies in Real Context
Email is a messy, threaded corpus. Good retrieval design — thread chunking, dedup, recency weighting — decides whether AI replies are trustworthy.

Most multimodal benchmarks test isolated perception, not the chained document-to-action tasks agents actually perform. Here's what better evaluation looks like.

Spreadsheet edits demand cell-level, deterministic evaluation — accuracy, reversibility, and formula integrity — not vibes-based scoring.

A diagnostic framework for why agentic workflows degrade over multi-step tasks — context loss, tool errors, and goal drift — plus concrete mitigations.

Reasoning depth should scale with task difficulty. Here's when chain-of-thought helps, when it hurts, and how to spend reasoning tokens wisely.

The clever one-liner prompt is fading. Durable AI work needs specifications: constraints, examples, and acceptance criteria you can reuse.

A decision framework for choosing constrained AI workflows over open-ended agents — and the specific conditions that justify going agentic.

How to build evals for subjective knowledge work — emails, summaries, docs — using rubrics, pairwise comparison, and human-in-the-loop sampling.

When a RAG pipeline gives bad answers, the LLM usually isn't the problem. Retrieval is. Here's where chunking, ranking, and recall actually break.

Public leaderboards reward the wrong things for agentic work. Here's a practical eval harness built around real task completion and side-effect safety.

Why LLMs should generate and execute formulas instead of hallucinating math — plus concrete patterns for verifiable spreadsheet automation.

Stuffing a million tokens into a prompt degrades reasoning more than it helps. The real skill is curating what the model actually attends to.
