implementing-database-caching

Process use when you need to implement multi-tier caching to improve database performance. This skill sets up Redis, in-memory caching, and CDN layers to reduce database load. Trigger with phrases like "implement database caching", "add Redis cache layer", "improve query performance with caching", or "reduce database load".

Quality

Content

92%Weight 40%Scale 1-3

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

A highly actionable, well-sequenced, and token-efficient body whose only real weakness is progressive disclosure: it never links out to the bundle, and the bundle files are disconnected stubs with misleading or missing entries.

Suggestions

Move the long Examples and the Error Handling table into reference files under ./references/ and link to them from the body so the SKILL.md stays an overview.

Wire the body to existing bundle assets (e.g., point to scripts/redis_setup.py and assets/monitoring_dashboard.png) and make redis_setup.py actually configure Redis rather than scaffold generic directories.

Fix scripts/README.md, which advertises redis_setup.sh, cache_invalidation.py, and cache_stats.py that do not exist in the bundle.

Dimension	Reasoning	Score
Conciseness	The body is dense and lean — it assumes Claude knows what Redis/caching are, never re-explains basics, and fills every section with specific values, commands, and config rather than padding.	3 / 3
Actionability	Guidance is concrete and copy-paste ready: exact Redis commands ('SET ... EX 3600', 'SET key:lock NX EX 5'), config values (maxmemory 75%, allkeys-lru, tcp-keepalive 60), per-data-type TTLs, named libraries, and metric formulas — no pseudocode.	3 / 3
Workflow Clarity	A clear numbered 1–10 sequence with an explicit verification step (step 10: 'verify cache hit rate reaches 90%+'), monitoring/alerting thresholds (step 9), and an Error Handling table providing feedback loops (circuit breaker, retry, audit invalidation) for recovery.	3 / 3
Progressive Disclosure	The body is well-sectioned but monolithic — it references none of the bundle files, keeps Examples/Error-Handling inline that could live in references, and the bundle itself is messy (stub READMEs; scripts/README.md lists redis_setup.sh, cache_invalidation.py, cache_stats.py that do not exist; redis_setup.py is generic scaffolding, not Redis setup).	2 / 3

Description

90%Weight 40%Scale 1-3

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, specific description with explicit trigger guidance and a clear niche; its only weakness is the second-person 'you need to' phrasing and the garbled 'Process use when' opening, which cost it the specificity point.

Suggestions

Rewrite in third-person voice (e.g., 'Implements multi-tier caching to improve database performance') to avoid the second-person penalty.

Fix the garbled opening 'Process use when...' into a clean leading verb clause.

Dimension	Reasoning	Score
Specificity	It lists multiple concrete actions ('sets up Redis, in-memory caching, and CDN layers'), which would be a 3, but the second-person phrase 'you need to implement' triggers the rubric's −1 specificity penalty for non-third-person voice.	2 / 3
Completeness	It clearly answers both what ('implement multi-tier caching...sets up Redis, in-memory caching, and CDN layers') and when via an explicit 'Trigger with phrases like...' clause, so it is not capped at 2.	3 / 3
Trigger Term Quality	It supplies four natural trigger phrases a user would actually say ('implement database caching', 'add Redis cache layer', 'improve query performance with caching', 'reduce database load'), giving good coverage of the niche.	3 / 3
Distinctiveness Conflict Risk	The multi-tier database-caching niche with Redis/in-memory/CDN and caching-specific triggers is clearly bounded and unlikely to fire for unrelated skills.	3 / 3
