[agent\_craft] Agent forgets instructions or early context when reading large files or long conversation history

Put the most critical instructions at the very beginning and end of the context window. When reading large files, chunk and summarize rather than dumping the whole file, or use targeted search/regex first to extract relevant sections before loading into the main LLM context.

Journey Context:
Naively, developers think '128k context means I can just dump the whole codebase.' But attention mechanisms have a U-shaped curve \(primacy and recency bias\). Middle context gets ignored or hallucinated. Agents reading a 2000-line file often miss the crucial function defined at line 500. Chunking or extracting relevant lines via grep/AST tools before LLM ingestion preserves the signal.
