system-design-integration-patterns skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.
system-design-integration-patterns is agent-read markdown (skill) from hoangnguyen0403/agent-skills-standard: Choose distributed integration and evolution patterns by the constraint each removes: outbox, CQRS, event sourcing, saga orchestration or choreography, leader election, sidecar, anti-corruption layer, and strangler-fig migration. Use when services must stay consistent across a boundary..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Integration Patterns ## **Priority: P1 (HIGH)** Each pattern buys one guarantee and charges operational complexity. Adopt on evidence, not on architecture fashion. ## Selection Table | Constraint observed | Pattern | Cost accepted | | --- | --- | --- | | A write must update the database and publish an event atomically | Transactional outbox | A relay (poller or CDC) to run and monitor | | Read shape and write shape have diverged and one model serves neither | CQRS | Two models, sync lag, doubled tests | | The sequence of changes is itself the product (audit, replay, temporal queries) | Event sourcing | Projections, event versioning, no easy delete | | A business transaction spans services and cannot hold a lock | Saga with compensations | Compensating action per step; no isolation | | Exactly one instance may run a job or own a resource | Leader election (lease-based) | Fencing tokens; split-brain handling | | Cross-cutting concerns repeated in every service | Sidecar or ambassador | Another process per pod to operate | | A legacy or third-party model would infect the domain | Anti-corruption layer | A translation layer to maintain | …
