Description

Substack deep-dive (March 30, 2026) intercepting and publishing the full Claude Code API request structure for a session using agents, rules, skills, and CLAUDE.md. Documented the fixed request assembly order: deferred tool list -> skill list -> CLAUDE.md -> project rules -> memories -> user message. Established that CLAUDE.md appears in a block at the start of the first user message, not in the API system field.

Key claims

• Skills use lazy invocation; once invoked they stay in context
• Claude Code API requests follow a fixed assembly order

Relations

• Justacuriousengineer Analysis --[uses]--> Proxy Verification Methodology
