Authoring Plugins

This section introduces the plugin‑first host and groups plugin documentation by topic. The host resolves dotenv context once per invocation, overlays config (JSON/YAML/JS/TS), validates, and then runs plugins and subcommands under that context.

• Lifecycle & Wiring - Covers defining and wiring plugins against the host.
• Config & Validation - Explains config overlays, interpolation timing, and validation.
• Diagnostics & Errors - Covers error handling, capture, and optional trace/redaction.
• Executing Shell Commands - A focused deep dive for subprocesses across plugins.
