caching-strategy

caching-strategy is a skill for Claude Code from berkcangumusisik/claude-code-practices. It costs 19 tokens per session (366 once invoked), scanned A, original, MIT.

A workflow for adding caches—temporary stored results—to slow database queries, calculations, external API responses, or HTTP responses.

In plain words
What is it for?
Use it to choose between Redis, in-memory storage, browser or CDN caching, and client-side caching, then add cache keys, expiration, and invalidation after changes.
Why use it?
It can reduce repeated work and waiting when the same data is requested often, while considering when cached data would be unsafe or stale.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

caching-strategy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Caching Strategy

Target: $1 (or analyze top bottlenecks if not specified)

  1. Identify cacheable operations:
grep -rn "db\.\|prisma\.\|fetch\|axios" ${1:-src/} --include="*.ts" | grep -v "test\|spec" | head -20

What's cacheable?

  • Query results that change infrequently (user profile, product catalog)
  • Expensive computations (aggregations, reports)
  • External API responses (weather, exchange rates)

What's NOT cacheable?

  • User-specific real-time data
  • Transactional operations
  • Anything that must be consistent
  1. Choose caching layer by use case:

    • Redis: shared across instances, TTL, pub/sub invalidation
    • In-memory (Map): single instance, fastest, lost on restart
    • HTTP Cache-Control: browser/CDN caching for GET responses
    • React Query / SWR: client-side data caching
  2. Implement with proper cache keys:

const cacheKey = `user:${userId}:profile`
const cached = await redis.get(cacheKey)
if (cached) return JSON.parse(cached)

const result = await db.user.findUnique(...)
await redis.set(cacheKey, JSON.stringify(result), 'EX', 300) // 5min TTL
  1. Add cache invalidation on mutations.

  2. Show estimated performance improvement.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

caching-strategy is a skill published in the GitHub repository berkcangumusisik/claude-code-practices (10 stars, last pushed 4mo ago), licensed MIT. It adds 19 tokens to every session and 366 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
