caching-strategy

caching-strategy is a skill for Claude Code, Codex from aj-geddes/useful-ai-prompts. It costs 38 tokens per session (635 once invoked), scanned A, original, MIT.

A guide to storing frequently used data temporarily so applications can retrieve it faster, using systems such as Redis, Memcached, or a content delivery network. It also covers deciding when stored data must be refreshed or removed.

In plain words
What is it for?
Use it to cache API responses, database results, computations, sessions, and static files, or to support distributed caching, rate limiting, and traffic control.
Why use it?
Repeated database queries or expensive calculations can slow an application and overload its backend. Caching can reduce that repeated work and improve response times when data is reused.

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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-api.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Caching Strategy

Table of Contents

Overview

Implement effective caching strategies to improve application performance, reduce latency, and decrease load on backend systems.

When to Use

  • Reducing database query load
  • Improving API response times
  • Handling high traffic loads
  • Caching expensive computations
  • Storing session data
  • CDN integration for static assets
  • Implementing distributed caching
  • Rate limiting and throttling

Quick Start

Minimal working example:

import Redis from "ioredis";

interface CacheOptions {
  ttl?: number; // Time to live in seconds
  prefix?: string;
}

class CacheService {
  private redis: Redis;
  private defaultTTL = 3600; // 1 hour

  constructor(redisUrl: string) {
    this.redis = new Redis(redisUrl, {
      retryStrategy: (times) => {
        const delay = Math.min(times * 50, 2000);
        return delay;
      },
      maxRetriesPerRequest: 3,
    });

    this.redis.on("connect", () => {
      console.log("Redis connected");
    });

    this.redis.on("error", (error) => {
// ... (see reference guides for full implementation)

Best Practices

✅ DO

  • Set appropriate TTL values
  • Implement cache warming for critical data
  • Use cache-aside pattern for reads
  • Monitor cache hit rates
  • Implement graceful degradation on cache failure
  • Use compression for large cached values
  • Namespace cache keys properly
  • Implement cache stampede prevention
  • Use consistent hashing for distributed caching
  • Monitor cache memory usage

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 aj-geddes/useful-ai-prompts (338 stars, last pushed 6mo ago), licensed MIT. It adds 38 tokens to every session and 635 once invoked, about $0.0002 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 2026-08-30.
