+# Safer responses and simpler workflow setup
+
+- Add `yskill respond` so agents can answer a pending step without building a
+  response file by hand.
+- Serialize responses per run across processes, recover exact retries, and
+  refuse conflicting content.
+- Enforce declared `AskUser` options in the TypeScript, Python, Go, and Rust
+  SDKs.
+- Let `yskill doctor` check a workflow without requiring agent adapters, and
+  keep fixture test runs temporary by default.
+- Add bulk adapter registration, safe synchronization, terminal-run pruning,
+  relocatable Python workflows, and deterministic fixture effects.
+- Verify 40 workflow cases and eight runtime checks, including concurrent
+  response admission and recovery.
