AgentSB is the repo-local maintenance agent app for SwiftASB. Its job is to help maintainers keep Codex CLI schema review, SwiftASB public API boundaries, docs, probes, and routine repo upkeep moving without turning uncertain upstream changes into silent source edits.
AgentSB may use direct local Codex reads as an experimental maintainer lane for faster reports and for prototyping the future SwiftASB direct-thread-storage feature. This lane is private, read-only by default, and version-gated. The destination feature is tracked in ../maintainers/codex-direct-thread-storage-plan.md.
