Report #78847

[agent\_craft] Context window exceeded when adding multiple file contexts

Use 'center-weighted' context placement: place most relevant code at the start \(0-10%\) and end \(90-100%\) of context window, with less critical files in middle; models pay less attention to center content due to U-shaped attention patterns.

Journey Context:
Research shows U-shaped attention patterns in transformers - middle positions get less attention. Common mistake is chronological ordering \(oldest files first\). Tradeoff: requires parsing files to identify 'relevant' symbols. Alternative of 'truncation from bottom' loses recent changes which are often most relevant. Specific technique: place system prompt, then API docs \(static\), then active file \(start\), then related files \(end\), with imports/interface definitions in prime positions. Never place tool definitions in the middle of file context.
