At a glance

Implement multi-level caching, invalidation patterns, and stampede protection in NestJS.

  • Adding Redis caching layers

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Configuring cache-manager interceptors

What it does

Nestjs Caching is an agent skill from HoangNguyen0403/agent-skills-standard. Implement multi-level caching, invalidation patterns, and stampede protection in NestJS. Use when adding Redis caching layers, configuring cache-manager interceptors, implementing stale-while-revalidate, or preventing cache stampedes in NestJS services.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/example.md`).

It sits in Backend & APIs, covering Caching. It works with NestJS and Redis. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Adding Redis caching layers
  • Configuring cache-manager interceptors
  • Implementing stale-while-revalidate
  • Preventing cache stampedes in NestJS services

Example prompts

  • “/nestjs-caching”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Nestjs Caching loads about 601 tokens when it runs, and up to ~726 if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 217 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~601
With references · SKILL.md plus every file in references/, read only if the agent opens them
~726

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Caching & Redis Standards

Priority: P1 (HIGH)

Caching Strategy

  • Layering: Use Multi-Level Caching for high-traffic read endpoints.
  • L1 (Local): In-Memory (Node.js heap). Ultra-fast, no network. Use lru-cache for config/static data.
  • L2 (Distributed): Redis. Shared across pods.
  • Pattern: Implement Stale-While-Revalidate to avoid latency spikes during cache misses.

NestJS Implementation

  • Library: Use cache-manager with cache-manager-redis-yet (recommended over cache-manager-redis-store for V4 stability).
  • Interceptors: Use @UseInterceptors(CacheInterceptor) for simple GET responses.
  • Warning: Default key URL. Ensure consistent query param ordering or use custom key generators.

See implementation examples

Stampede Protection

  • Jitter: Add random variance to TTLs to prevent simultaneous expiry across keys.
  • Locking: One process recomputes while others wait or return stale data.

See implementation examples

Redis Data Structures

  • Hash (HSET): Store objects (user profiles) with partial update support.
  • Set (SADD): Unique collections with O(1) membership checks.
  • Sorted Set (ZADD): Priority queues, leaderboards, rate-limiting windows.

Invalidation Patterns

  • Tagging: Use Sets to group cache keys (avoid KEYS which O(N) in production).
  • Create: SADD post:1:tags cache:post:1
  • Invalidate: Fetch tags from Set, then DEL grouped keys.
  • Event-Driven: Listen to domain events (UserUpdated) to trigger invalidation asynchronously.

Anti-Patterns

  • No KEYS in production: Use SET-based tag grouping for cache invalidation; KEYS O(N).
  • No fixed TTLs on grouped caches: Add jitter (±10s) to prevent simultaneous stampede.
  • No MemoryStorage for multi-pod: Use Redis store; in-memory cache not shared across pods.
