Archive completed tasks and trim stale context entries to keep the context directory lean and within token budgets. ## When to Use - When TASKS.md has many completed items - When context token count is growing large - When asked to "clean up" or "compact" context - Before starting a new phase of work ## When NOT to Use - When all tasks are still active - When context is already compact ## Execution Run the compact operation: ```bash ctx compact ``` This archives completed tasks from TASKS.md into the session history and trims stale entries from other context files. After running, confirm: - How many tasks were archived - Current token budget usage - Whether any manual cleanup is recommended
