docs: warn that compaction summary model must match main model context length - #7879
Merged
Conversation
The summary model used for context compaction must have a context window at least as large as the main agent model. If it's smaller, the summarization API call fails and middle turns are dropped without a summary, silently losing conversation context. Promoted the existing note in configuration.md to a visible warning admonition, and added a matching warning in the developer guide's context compression page.

Summary
The summary model used for context compaction must have a context window at least as large as the main agent model's. If it's smaller, the
call_llm(task="compression")call fails with a context-length error, and the middle turns are dropped without a summary — silently losing conversation context.Changes
