This skill enables Claude to implement multi-tier database caching solutions. It is triggered when the user requests database caching, performance improvements, or reduced database load. The skill utilizes Redis, in-memory caching, and CDN layers to optimize database performance by reducing database load, improving query latency, and supporting horizontal scaling with cache-aside, write-through, and read-through patterns. Use this skill when the user mentions terms like "database caching", "improve database performance", "reduce database load", or uses the `/caching` command.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong skill description that clearly articulates what it does (multi-tier database caching with specific technologies and patterns), when to use it (explicit trigger terms and a command), and occupies a distinct niche. The description is comprehensive without being overly verbose, and uses appropriate third-person voice throughout.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions and technologies: Redis, in-memory caching, CDN layers, cache-aside/write-through/read-through patterns, reducing database load, improving query latency, and supporting horizontal scaling. | 3 / 3 |
Completeness | Clearly answers both 'what' (implement multi-tier database caching with Redis, in-memory caching, CDN layers, various caching patterns) and 'when' (explicit 'Use this skill when...' clause with specific trigger terms and a command). | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'database caching', 'improve database performance', 'reduce database load', '/caching' command, 'performance improvements'. These cover common variations of how users would phrase caching-related requests. | 3 / 3 |
Distinctiveness Conflict Risk | Clearly scoped to database caching specifically, with distinct triggers like '/caching' command and specific technologies (Redis, CDN layers, cache-aside patterns). Unlikely to conflict with general performance or database skills due to the narrow caching focus. | 3 / 3 |

Implementation
7%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill content is essentially a high-level description of what caching is and what Claude would do, rather than actionable instructions for how to implement caching. It contains no executable code, no concrete configuration examples, and no validation steps. The content explains concepts Claude already understands while failing to provide the specific, copy-paste-ready implementations that would make this skill useful.
Suggestions
Replace the abstract 'Example' descriptions with actual executable code showing Redis connection setup, cache-aside pattern implementation, and in-memory caching with specific libraries (e.g., Node.js with ioredis or Python with redis-py).
Add validation checkpoints such as testing cache connectivity, verifying cache hit/miss ratios, and confirming data consistency between cache and database.
Remove the 'How It Works', 'When to Use', and 'Integration' sections entirely—they describe meta-information Claude doesn't need—and replace them with concrete implementation patterns and configuration snippets.
Add a troubleshooting section covering common failure modes like cache stampede, connection pool exhaustion, and serialization errors with specific solutions.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is verbose and explains concepts Claude already knows well (what caching is, what Redis does, what cache-aside means). The 'How It Works' and 'When to Use' sections restate the description. Nearly every section describes rather than instructs, wasting tokens on meta-commentary about what 'the skill will do' instead of providing actual implementation guidance. | 1 / 3 |
Actionability | There is zero executable code anywhere in the skill. The examples describe what the skill 'will do' in abstract terms rather than providing concrete code, commands, or copy-paste-ready implementations. A caching skill should include actual Redis connection setup, cache-aside pattern code, and configuration examples. | 1 / 3 |
Workflow Clarity | The multi-step processes listed are vague descriptions ('Generate code to integrate Redis') rather than clear, sequenced steps with validation checkpoints. There are no verification steps, no error handling guidance, no feedback loops for cache invalidation testing or connection validation. | 1 / 3 |
Progressive Disclosure | The content has some structural organization with clear section headers (Overview, Examples, Best Practices), but everything is inline with no references to external files for detailed implementations. The content that exists is too shallow to benefit from splitting, but the lack of depth means there's nothing substantial to progressively disclose. | 2 / 3 |
