Building applications with Axon Framework 5 (AF5) and Axoniq Framework. Covers all aspects of AF5 application development: command handlers (stateless and DCB/stateful), event-sourced entities (@EventSourcedEntity, @EntityCreator, @InjectEntity, entity hierarchies and polymorphism), dispatching commands (CommandGateway/CommandBus, routing keys); event handling and projections, event processors (subscribing and pooled streaming, tracking tokens, segments, replay/reset), publishing events (EventAppender, EventGateway), event versioning and upcasting; query handling and subscription queries; event store primitives (EventStoreTransaction, SourcingCondition, AppendCondition, ConsistencyMarker, EventCriteria, Tag, @EventTag), event store internals (EventStore, EventStorageEngine), conversion and serialization (Converter, Jackson, Avro); messaging foundations (message anatomy, ProcessingContext/unit of work, correlation, Metadata), supported handler parameters, message annotations, exception handling (@ExceptionHand
Internal helper, invoked ONLY by other skills (e.g. axon4to5-migrate-code). Scopes Maven/Gradle compile+test to ONE target class plus all classes required for it to compile, via per-target profile or source-set. Do NOT auto-trigger from user prompts.
Apply the Axon Framework 4 → 5 OpenRewrite bulk-migration recipe (maven or gradle, free or commercial variant). Use when the user says "run openrewrite", "apply axon migration recipe", "axon4to5-openrewrite", "migrate to axon 5", or "migrate to axoniq 5". Detects build tool, picks the recipe by --framework, runs, offers to commit. Idempotent — safe to re-run.
Add a reference repository under .knowledge/repositories. Clones it locally (shallow), writes a per-repo detail markdown file with frontmatter, updates the type-level INDEX.md catalog, and registers the repo in setup-repos.sh. Use this whenever the user wants to add a reference repository, external repo, migrated application example, framework reference, or any git repository as a tracked reference - even if they don't say "submodule" explicitly. Triggers on phrases like "add this repo", "add a reference", "include this repository", "track this repo as", "add as submodule", "add migrated example", "add reference application".
Migrate Axon Framework 4 project code and configuration to Axon(iq) Framework 5. Migrates source code and wiring only — NOT stored data (event store contents / stored events, tracking tokens), which are left untouched.
Design patterns and principles for building Axon Framework core components. Covers layered API design, component lifecycle, thread safety, and extension points. Use when developing infrastructure components for Axon Framework itself.
Add or update Axon Framework 5 reference documentation. Use when the user says "add docs", "update docs", "document feature", "write documentation for", "update the reference guide", "add a page", "edit the docs", "adapt documentation", or any variation of creating or editing AsciiDoc pages in the Axon Framework docs.
Process GitHub PR review comments one by one for an Axon Framework pull request. Use when the user says "process PR comments", "work through review comments", "handle review feedback", "go through PR feedback", or provides a GitHub PR URL or PR number and wants to address reviewer comments systematically.
