Claude Code Best Practices: Reliable, Cheap, High-Leverage Sessions

Synthesise the whole Claude Code track into working habits: manage the context window deliberately, always give Claude a check it can run, plan before touching code, prompt with acceptance criteria, scope permissions narrowly, control cost, and know how to recover when a session goes wrong.

CLAUDE.md and Context Configuration

Understand why CLAUDE.md exists and how it composes with auto memory and settings.json, how to write instructions that survive a growing context window instead of bloating it, and how to back a probabilistic agent with deterministic guardrails using permissions and hooks.

Transformers for AI Engineers

Covers what an AI Engineer interview actually probes about transformer internals: scaled dot-product and multi-head attention, why decoder-only architectures won, why the KV cache exists and how its memory footprint is computed, what parameter count does and doesn't predict, and positional encoding — with worked numbers for KV cache memory and prefill-vs-decode cost.
