Designs multi-layer caching - CDN, application, and database - choosing the pattern, TTL, and invalidation plan per data type, and produces a cache-decision table plus stampede protection. Use when someone asks "should I cache this", "Redis or CDN for this endpoint", "how do I invalidate this cache", "why is my cache hit rate so low", or is bolting Redis onto a slow service. Do NOT use for sizing or tuning database connection pools - use connection-pool-tuner instead - and do NOT use for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Caching Strategy A cache is a correctness liability you accept in exchange for latency, so every cache needs an explicit answer to "how stale can this be?" and "how does it get invalidated?" before it ships. The costly mistake this skill prevents is the write-only cache: a layer that adds a network hop and an invalidation bug surface while its hit rate quietly sits below 50 percent, making the system slower and wronger at the same time. ## Operating procedure Work per data type, not per system - "cache the API" is not a decision, "cache the product listing for 60s at the CDN" is. ### Step 1: Gather inputs Collect these for each candidate data type. If a number is an estimate, label it a guess and refine from production metrics later. 1. Read:write ratio. How many reads per write to the same key. 2. Recompute cost. Latency of a cache miss (DB query, computation, upstream call). 3. Staleness tolerance. How stale a value can be before it causes a user-visible or business-logic error. Get a number in seconds, not "pretty fresh". 4. Key cardinality and object size. Millions of small keys behave differently from thousands of megabyte blobs. …

How to install
mdr add skillmedev/skills/caching-strategy@sha256:fd6be302d71de81eThe line at the top of this page pins the label git:20261005.bea4ea5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
