Use when editing `~/.system2/config.toml` — adding or modifying a database connection, tuning per-agent overrides, or changing operational defaults. Does NOT cover `~/.system2/auth/.auth.toml` (managed by `system2 config`).
Run on first launch (when ~/.system2/knowledge/infrastructure.md is still the template) or whenever the user explicitly asks to re-onboard. Greets the user, learns about them, detects the system, installs and configures the data stack (database, orchestrator, Python environments), scaffolds the pipeline repository, and captures interaction preferences.
Use when building, debugging, deploying, or testing data pipelines with Prefect v3. Trigger on any code importing prefect, prefect YAML config, or user mentioning Prefect flows/tasks/deployments/workers.
Run before declaring project work complete. A self-audit checklist to honestly assess whether the deliverables actually meet the requirements before requesting final review or reporting completion to the Guide.
Run when delegating complex work to a new project. Gathers preliminary requirements with the user, creates the project in app.db, spawns a Conductor and Reviewer, introduces them to each other, updates the user, and schedules a follow-up reminder so a silent Conductor is noticed.
Build interactive HTML dashboard artifacts with live database queries via the postMessage bridge. Includes a copy-paste helper function, workflow steps, and Chart.js integration patterns.
