+- **Named workspaces** with consistent layout (task metadata, agent instructions, notes, context, output, logs)
 - **Session traceability** -- automatic file-change snapshot logging on every session
-- **Agent-agnostic** -- default agent is Claude Code, but any CLI agent or shell works
+- **Agent-agnostic** -- built-in profiles for Claude Code and OpenCode, plus a `custom` escape hatch for any CLI agent or shell
+- **Global config** -- optional user-level config file for defaults (agent, roots, session mode), with source attribution in `doctor`
+- **Session recovery** -- PID-aware lease detection: a workspace whose owner process has died is recovered immediately, with no stale-wait
 - **Query resolution** -- find workspaces by name, slug, or substring
 - **Status line** -- persistent session context inside Claude Code's UI
-- **Doctor** -- verify setup and diagnose configuration problems
+- **Doctor** -- verify setup, diagnose configuration problems, and validate agent setup
 - **Safe delete** -- active workspace protection prevents accidental data loss
