Description
Adds design document 0009: Context Offloader. This documents the
ContextOffloaderplugin that intercepts oversized tool results viaAfterToolCallEvent, stores each content block individually to a pluggable storage backend with content type preserved, and replaces the in-context result with a truncated preview plus per-block storage references. Includes a built-inretrieve_offloaded_contenttool (enabled by default) so the agent can fetch offloaded content on demand.Implements token-based thresholds using the model's
countTokensmethod, with three storage backends:InMemoryStorage,FileStorage, andS3Storage.Python implementation: sdk-python#2162. TypeScript implementation: sdk-typescript#974.
Part of the context management roadmap.
