-- Design and implement a retrospection mode or dedicated subcommand / prompt pattern.
-- During retrospection, the agent helps the user:
-  - Review recent interactions and memory usage.
-  - Reflect on what helped or didn't.
-  - Explicitly set or refine goals, preferences, and "rules for future interactions."
-- Store retrospection outputs as durable memory (stabilized phase where appropriate).
+**Done** — implemented.
 
-**Acceptance criteria**:
-- A user can run a retrospection session and have its outcomes affect future assistance.
-- The flow feels natural in a terminal and respects user control.
+- Added `cya retrospect` subcommand in `src/cya/cli/main.py`.
+- Implemented `run_retrospection()` in `src/cya/orchestrator.py`:
+  - Reviews recent memory in the given scope.
+  - Guides the user through reflection questions.
+  - Records outcomes using the T02 `remember_retrospection_outcome` helper (stored as retrospection / interaction_goal kinds).
+  - Uses rich panels for a pleasant terminal experience.
+- The command is discoverable (`cya --help` shows the `retrospect` subcommand).
+- Outcomes are stored in the same user-controlled memory store and will be activated in future normal sessions (per T03 activation logic).
+
+**Acceptance criteria met** (MVP):
+- A user can run `cya retrospect` and capture goals/preferences that affect future assistance.
+- The flow is natural, guided, and fully respects user control (they decide what to record).
 
 ### T05 — Close the continuous optimization loop
