The 'What is covered' bullet list is essentially a table of contents for the reference file and adds moderate bloat. The description section and 'When to use this skill' section repeat information from the YAML frontmatter. However, the workflow and constraints sections are reasonably tight.

The skill provides concrete commands (mvnw compile, mvn clean verify) and a clear workflow, but lacks any executable code examples of the actual exception handling patterns. All concrete guidance is deferred to the reference file, so the SKILL.md itself gives only abstract direction like 'Refactor to specific exceptions, safe resource handling.'

The workflow is clearly sequenced with four explicit steps, includes a pre-condition check (compile before changes), a stop-if-fail checkpoint, and a post-change verification step. The feedback loop of compile → stop on failure → apply → verify is well-defined for a potentially destructive refactoring operation.

The skill correctly references a single external file (references/126-java-exception-handling.md) for detailed patterns, which is good one-level-deep disclosure. However, the long bullet list of covered topics is essentially inlining a summary of the reference file's contents, which bloats the overview. Without the bundle file provided, we cannot verify the reference path exists, but the structure is reasonable.

The description lists numerous specific concrete actions: using specific exception types, managing resources with try-with-resources, securing exception messages, preserving error context via exception chaining, validating inputs with fail-fast principles, handling thread interruption, documenting exceptions with @throws, enforcing logging policy, translating exceptions at API boundaries, managing retries and idempotency, enforcing timeouts, attaching suppressed exceptions, and propagating failures in async/reactive code.

The description clearly answers both 'what' (a comprehensive list of Java exception handling best practices) and 'when' (explicitly starts with 'Use when you need to apply Java exception handling best practices' and includes specific trigger phrases like 'This should trigger for requests such as...').

The description includes many natural keywords users would say: 'exception handling', 'try-with-resources', 'exception chaining', 'fail-fast validation', 'Java code', '@throws', 'retries', 'timeouts', 'async/reactive code'. The explicit trigger examples ('Exception handling; Use try-with-resources in Java code; Create exception chaining in Java code') further reinforce natural user language.

The description is highly specific to Java exception handling best practices, a clear niche that is unlikely to conflict with other skills. The domain (Java), the topic (exception handling), and the numerous specific sub-topics make it very distinguishable from other skills.
