authoring-java-sdk-tasks

Writes Airflow task logic in Java, Kotlin, or any JVM language using the Airflow Java SDK. Use when the user wants to implement Airflow tasks in Java/JVM, asks about `@Builder.Dag`/`@Builder.Task`/`@Builder.XCom`, the `Task`/`BundleBuilder` interfaces, reading connections/variables/XComs from Java, the JSON-to-Java type mapping, or logging from Java tasks. This skill covers the Java-specific native API; the shared Python-stub pattern and conceptual model live in authoring-language-sdk-tasks. For building/shipping the bundle see deploying-java-sdk-bundles; for coordinator config see configuring-airflow-language-sdks.

Quality

Content

82%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, actionable reference for the Java SDK: executable code for both APIs, precise API tables, and clear cross-skill navigation. It is efficient and assumes Claude's competence, with only minor duplication and no explicit validation-checkpoint workflow (not needed here given the non-destructive scope).

DimensionReasoningScore

Conciseness

The body is lean and stays on SDK-specific details (annotations, interfaces, XCom JSON mapping) without explaining concepts Claude already knows; minor trim opportunities exist in the Python-side recap and the Related-skills block being stated both as a callout and a closing section.

4 / 5

Actionability

Copy-paste-ready, executable Java for both the annotation and interface APIs, the bundle entry point, plus precise Client/Context and XCom-type tables that cover the common authoring cases.

5 / 5

Workflow Clarity

Section order mirrors the real authoring flow (Python stub → Java task → entry point → build/deploy) and correctness gates (ID matching, JSON-type matching) are called out as failure conditions; it lacks explicit validate-then-proceed checkpoints, but no destructive/batch operation triggers the cap-at-3 rule.

4 / 5

Progressive Disclosure

Well-organized sections with clearly signaled, one-level-deep cross-skill references (Related-skills callout, inline pointers, closing Related Skills list); no bundle files exist, and the focused Java API content is appropriately kept inline rather than over-split.

Description

95%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that states a concrete capability, gives explicit trigger guidance with the exact identifiers users would say, and cleanly separates its scope from three sibling skills. The only minor gap is that the action framing leans on a single verb plus enumerated topics rather than a fully comprehensive action list.

DimensionReasoningScore

Specificity

The lead verb 'Writes Airflow task logic in Java, Kotlin, or any JVM language using the Airflow Java SDK' is concrete, and it enumerates specific sub-capabilities (reading connections/variables/XComs, JSON-to-Java type mapping, logging); it stops short of a fully comprehensive action list, sitting between anchors 3 and 5.

4 / 5

Completeness

Explicitly answers both 'what' ('Writes Airflow task logic ... using the Airflow Java SDK', 'covers the Java-specific native API') and 'when' with a concrete 'Use when the user wants to implement Airflow tasks in Java/JVM, asks about ...' trigger clause.

5 / 5

Trigger Term Quality

Comprehensive natural-term coverage including synonyms (Java/JVM/Kotlin) and the exact identifiers users would mention — `@Builder.Dag`/`@Builder.Task`/`@Builder.XCom`, `Task`/`BundleBuilder`, connections/variables/XComs, type mapping, logging.

5 / 5

Distinctiveness Conflict Risk

It carves a clear Java-specific native-API niche and explicitly routes adjacent concerns to authoring-language-sdk-tasks, deploying-java-sdk-bundles, and configuring-airflow-language-sdks, minimizing wrong-skill triggering.
