Event-driven architecture — event sourcing, CQRS, sagas, schema evolution, consumer groups, partitions, idempotent handlers, outbox pattern, dead letter queues. Auto-load when designing event-driven systems, evaluating event sourcing or CQRS, planning saga workflows, implementing idempotent consumers or the outbox pattern, managing dead letter queues, or assessing whether event-driven architecture fits the problem.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- preload-canary: SWB-PRELOAD-PRINCIPLE-EVENT-DRIVEN --> # Event-Driven Architecture The log is the source of truth: producers emit immutable events; consumers react asynchronously. This decouples services at deployment and operational boundaries and lets new consumers replay history — at the cost of eventual consistency and significantly more failure surface area than synchronous calls. ## Event Sourcing Store every state change as an immutable event; derive current state by replaying the log. The aggregate's current state is a projection, not the record of truth. - Snapshots cap replay cost: persist a projected state checkpoint every N events and replay only from the latest snapshot. - Projections are disposable — design them to be rebuilt by replaying; avoid hand-rolled caches that drift from the log. - Event store must be append-only; mutating or deleting events destroys the audit trail and breaks replaying consumers. - GDPR erasure: store PII in a side-table and tombstone the key rather than mutating event history. ## CQRS (Command Query Responsibility Segregation) …

How to install
mdr add lugassawan/swe-workbench/principle-event-driven@sha256:78a47840f7714c50The line at the top of this page pins the label git:20260828.71a6399, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
