Lists multiple specific concrete actions: identifying failed/paused/long-running jobs, surfacing schema changes, backups/restores, automatic statistics collection, and SQL stats compaction jobs. Also specifies the SQL commands used (SHOW JOBS, SHOW AUTOMATIC JOBS).

Clearly answers both 'what' (monitors CockroachDB background job health by identifying failed/paused/long-running jobs, surfaces various job types) and 'when' (explicit 'Use when investigating schema change delays, failed backups, or automatic job issues').

Includes strong natural trigger terms users would say: 'CockroachDB', 'failed', 'paused', 'long-running jobs', 'schema change delays', 'failed backups', 'automatic job issues', 'SHOW JOBS', 'SHOW AUTOMATIC JOBS', 'DB Console'. Good coverage of both technical and natural language terms.

Highly distinctive with a clear niche: CockroachDB job monitoring specifically. The combination of CockroachDB, SHOW JOBS, and specific job types like backups/schema changes makes it very unlikely to conflict with other skills.

The skill is extremely verbose at ~400+ lines. It over-explains concepts Claude already knows (what PDFs are, what 'failed' status means, what 'permission denied' errors indicate), includes extensive tables defining obvious status values, and repeats information across sections (e.g., MVCC GC explanation appears in multiple places). The 'Core Concepts' section explaining jobs vs statements and status values is largely unnecessary padding.

All queries are fully executable SQL with proper CTE syntax for CockroachDB's SHOW JOBS interface. Key columns are explained, thresholds are customizable, and job control commands are concrete. The queries are copy-paste ready with appropriate LIMIT clauses and time window filters.

Workflows are clearly sequenced with numbered steps, include interpretation guidance at each stage, and have explicit decision points (e.g., 'If running_status = waiting for MVCC GC: Normal... If long-running with low fraction_completed: Check for contention'). Safety considerations include explicit validation checkpoints before destructive operations like CANCEL JOB, with clear warnings about risks by job type.

The skill references four bundle files (permissions.md, job-states.md, job-types.md, sql-query-variations.md) and related skills, which is good structure. However, no bundle files were provided, and the main SKILL.md contains substantial content that should be in reference files (e.g., the full job status values table, the job types table, common failure patterns). The core concepts section is essentially inline reference material that bloats the main file.
