Session Chaining

The practice of decomposing a large project into a sequence of specialised Claude Code sessions — discovery, planning, execution — where each session's output document becomes the next session's input, preserving continuity without bloating any single context.

Key points

• Discovery session: reads PDFs, codebases, raw sources → produces a concise summary document ^[src-011]
• Planning session: ingests the summary → produces a structured plan file ^[src-011]
• Execution session: ingests the plan → implements — no conversation history from prior sessions needed ^[src-011]
• Functions like an assembly line: each session has one specialised responsibility and a clean context ^[src-011]
• Complementary to the Session Handoff skill, which packages up mid-session state for a clean handover ^[src-011]
• Nate recommends this pattern especially for beginners building context discipline before using the full 1M token window ^[src-011]
• Addresses the root cause of Context Rot: by starting fresh, there is no history to re-read and no attention dilution ^[src-011]
