Inside Claude Code: six-layer agent architecture with prompt caching cutting costs to ~10%

A detailed X thread breaks down Claude Code's agent architecture: input layer (CLI/IDE/CI-CD, session manager, permission gate), knowledge layer (skill registry, task graph, context compressor, cross-session memory), the master agent loop (perception-action-observation), execution layer (typed tool dispatch, streaming parallel runtime, prompt cache cutting costs to 10%), and an observability layer with event bus and background executor.
