caching SKILL.md skillA
caching from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Decide what to cache, at which layer, for how long, and how it gets invalidated — before any cache is added. Use when someone proposes caching to make a read path faster, when stale or cross-user data is suspected, when adding a TTL or a Redis/CDN layer, or when reviewing a change that introduces one. Not for fixing a slow query or an N+1 (do that first — a cache over a bad query hides it), and not for HTTP header tuning with no server-side store.
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 A cache is a second copy of the truth that is allowed to be wrong. Adding one trades a latency problem for a correctness problem, and the correctness problem arrives later, in production, as "why is this user seeing yesterday's number". Never add a cache before you can say, in one sentence each: what is cached, keyed by what, for how long, and what makes it wrong. ## When this fires A read path is slow and caching is being proposed; a cache already exists and data is stale or leaking across users; a review touches a TTL, a memoize decorator, a Redis client, or a CDN rule. It does not fire for a write path, or for a slow query nobody has profiled yet. ## Procedure 1. **Measure the uncached path first.** Get a real number — p50 and p95, and how often it is called. Without it you cannot tell afterwards whether the cache helped, and you have no basis for the TTL. A cache added on a hunch is a guess with extra failure modes. 2. **Try to make the cache unnecessary.** A missing index, an N+1, a payload fetching columns nobody reads, or a call made in a loop are all cheaper to fix than to cache, and the fix has …

How to install
mdr add nahid-sparktales/agent-dispatcher/caching@sha256:b755ccf8cd860eb7The line at the top of this page pins the label git:20260919.a0d4f55, 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.
