Jobs: $ARGUMENTS

Read the repository first. AGENTS.md → ## Workflow → Jobs names the backend (default: pgbus through ActiveJob), the job directories and the recurring-schedule file. An app with two systems (ActiveJob jobs and Sidekiq workers) follows the pattern of the directory it is changing.

Writing a job

• Arguments are IDs and primitives, never records: plus the tenant ID when the record is tenant-owned.

Reload through the tenant root (Workflow → Tenant) and check the tenant still exists and still has the feature enabled before working. Changing an existing job's arguments is a rename: accept the old shape too until the queue has drained (jobs enqueued before the deploy still carry it).

• Idempotent: safe to run twice. Guard on persisted state, and re-check inside a lock:

``ruby def perform(tenant_id, thing_id) tenant = Tenant.find_by(id: tenant_id) # Workflow → Tenant names the root return unless tenant&.feature_enabled?(:things) # gone or switched off: nothing to do thing = tenant.things.find(thing_id) return if thing.processed? thing.with_lock do return if thing.processed? Things::Process.call(thing:) end end ``

• Retries: retry_on <transient error>, wait: :polynomially_longer, attempts: N with a cap;

discard_on ActiveRecord::RecordNotFound when the record may legitimately vanish. Never unbounded retries; never retry_on StandardError around work that is not idempotent.

• Business logic lives in a service (/rails-app:services); the job loads, guards and calls it.
• Fan-out: a parent iterates find_each/in_batches and enqueues one child per batch. Never one job

that walks every tenant in one transaction.

• Queue: pick the existing queue whose latency matches; a new queue also needs the worker config.

Removing or renaming a job class

A payload already enqueued, a retry in flight, a dead-letter row or a schedule entry can still name the old class, and fails with ActiveJob::UnknownJobClassError/NameError after the deploy.

1. Remove the schedule entry in the same PR (grep the schedule file for class: <Name>).
2. Keep the old class (or an alias constant delegating to the new one) until the queue and dead

letters hold no payload naming it; then delete it in a later PR.

Recurring and one-off work

• Recurring: an entry in the schedule file Workflow → Jobs names; the job itself stays idempotent

(overlapping runs happen).

• An after-deploy backfill: an idempotent job or task, listed per Workflow → PR contract when a human

runs it.

Spec

• Job spec with perform_now: the happy path, the guard (run it twice, the effect happens once), the

missing record, the tenant without the feature.

• Callers: expect { … }.to have_enqueued_job(ThingJob).with(thing.id).

Done when the specs are green and Workflow → Verify passes.
