Codex Analysis Platform Tutorial: Build Code Intelligence Systems

Design and operate a production-grade code analysis platform with parsing, symbol resolution, code intelligence features, LSP integration, and rollout governance.

Why This Track Matters

Most engineering teams rely on code intelligence features but do not understand how they are built or operated.

This track focuses on:

• architecture of multi-language analysis systems
• AST and symbol pipelines that power developer tooling
• practical LSP implementation patterns
• production rollout, governance, and CI automation

Current Snapshot (auto-updated)

• repository: microsoft/TypeScript
• stars: about 109k
• GitHub release reference: v6.0.3 (checked 2026-06-08; release metadata on GitHub)
