+# agent_orchestrator
+
+On session start, load context:
+```bash
+ctx get agent_orchestrator
+```
+
+Context manager: `ctx --help`
+
+During work:
+- Save important discoveries: `ctx set agent_orchestrator <key> <value>`
+- Append to existing: `ctx append agent_orchestrator <key> <value>`
+- Before ending session: `ctx summary agent_orchestrator "<what was done>"`

+## External AI consultation (OpenRouter)
+
+Consult other models (GPT, Gemini, DeepSeek, etc.) for code review, cross-checks, or analysis:
+```bash
+consult "question"                        # ask default model
+consult -m model_id "question"            # ask specific model
+consult -f file.py "review this code"     # include file
+consult                                   # show available models
+```
+
+## Task management (CLI tool)
+
+IMPORTANT: Use the `tasks` CLI tool via Bash — NOT the built-in TaskCreate/TaskUpdate/TaskList tools.
+The built-in task tools are a different system. Always use `tasks` in Bash.
+
+```bash
+tasks list agent_orchestrator                           # show all tasks
+tasks context agent_orchestrator                        # show tasks + next task instructions
+tasks add agent_orchestrator "description"              # add a task
+tasks done agent_orchestrator <task_id>                 # mark task as done
+tasks --help                                # full help
+```
+
+Do NOT pick up tasks on your own. Only execute tasks when the auto-trigger system sends you a command.
