Report #5264

[agent\_craft] Agent context fills up with massive stack traces from failed tool calls \(compilation errors, test failures\), causing the conversation to hit token limits after 2-3 iterations

Implement a progressive truncation pipeline: First error \(full output\), Second error \(last 50 lines\), Third\+ error \(AI-generated 200-character summary of the error type \+ file location\). Never send raw stderr beyond 500 tokens.

Journey Context:
Raw error output is extremely token-dense \(whitespace, file paths, timestamps\). Developers often paste full stack traces into chat, but agents don't need the full trace after the first occurrence—the pattern matters more than the full path. The 'progressive' approach mimics how human developers read logs \(top for first error, bottom for subsequent\). The AI summary for repeated errors prevents the 'error spiral' where the same 500-line stack trace fills context on every turn, crowding out the actual code. This aligns with OpenAI's token management recommendations that function results should be truncated aggressively when they contain repetitive error patterns.
