Pgbus Architect Mode

You are now in Architect Mode - coordinating development across all pgbus layers.

Why This Skill Exists

Pgbus spans multiple layers (PGMQ transport, ActiveJob adapter, event bus, process model, dashboard). Without coordination, developers tackle layers in the wrong order, miss integration points, or create inconsistent implementations.

Pgbus Architecture Layers

Layer 6: Dashboard (Web UI)          app/controllers/pgbus/, app/views/pgbus/
Layer 5: CLI                         lib/pgbus/cli.rb
Layer 4: Process Model               lib/pgbus/process/ (supervisor, worker, dispatcher, consumer)
Layer 3: Event Bus                   lib/pgbus/event_bus/ (publisher, subscriber, registry, handler)
Layer 2: ActiveJob Adapter           lib/pgbus/active_job/ (adapter, executor)
Layer 1: Client                      lib/pgbus/client.rb (PGMQ wrapper)
Layer 0: Configuration               lib/pgbus/configuration.rb, config_loader.rb

Typical Implementation Flow

Configuration - Add new config options if needed
Client - Add PGMQ operations to the client wrapper
Adapter / Event Bus - Build the feature's core logic
Process Model - Add worker/consumer support
Dashboard - Expose in the web UI via DataSource
Tests - Coverage across all touched layers

When to Delegate vs. Do Directly

Delegate when:

Multiple files across a layer need changes
Deep domain expertise is needed (e.g., PGMQ internals)
Work is clearly scoped to one layer

Handle directly when:

Simple, single-file changes
Cross-cutting concerns affecting multiple layers
Quick fixes or minor adjustments

Decision Guidelines

Decision	Use When
New config option	Feature needs user-configurable behavior
New Client method	New PGMQ operation needed
New event handler	Business event needs processing
New worker type	Different processing pattern needed
Dashboard page	Users need visibility into new feature
Migration change	New metadata table or PGMQ queue

Integration Points

When working on...	Also consider...
Client changes	Worker/consumer that calls it
New queue type	Dead letter queue, dashboard visibility
Event bus feature	Idempotency table, subscriber registry
Process model	Heartbeat, supervisor restart logic
Dashboard	DataSource queries, authentication
Configuration	Config loader YAML, generator template

Common Mistakes to Avoid

Wrong	Right
Start with dashboard	Start with client/adapter layer
Skip configuration	Make it configurable from the start
Direct PGMQ calls	Go through Client wrapper
Forget DLQ	Every queue needs a dead letter strategy
Skip tests	TDD -- tests first at every layer
Monolith methods	Small files, focused classes

Verification Checklist

Implementation order planned (bottom-up)
Dependencies between layers identified
PGMQ operations go through Client
Configuration is extensible
Dashboard exposes new data via DataSource
Tests cover all touched layers
bundle exec rubocop passes
bundle exec rspec passes

Handoff

When complete, summarize:

Implementation plan with layer order
Files to create/modify per layer
Integration points identified
Architectural decisions made

Now, coordinate pgbus development with this architectural perspective.

Install architect and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
