+* Flight Plan: System State and Shell Actuator
+:PROPERTIES:
+:STATUS: IN-PROGRESS
+:END:
+
+** Analyst Phase
+The user has requested an update on the state of the system and a test run to realize where it is failing and what features we were working on.
+We were implementing the Shell Actuator (=org-skill-shell-actuator.org=) to enable the agent to run commands like "date". We ran into connection/daemon-crashing issues and response formatting issues.
+
+** Coder Phase
+- [X] Create =inbox/flight-plan-system-state.org= (this file).
+- [ ] Run tests (=test-shell.lisp= and =prove-shell.el=).
+- [ ] Inspect daemon logs to find the exact failure points.
+
+** Tester Phase
+1. Start the daemon in the background using a robust method.
+2. Run =test-shell.lisp= and =prove-shell.el=.
+3. Review the output and identify the bugs.
