caching SKILL.md skillA

caching from dayfinggg/openai-codex-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add dayfinggg/openai-codex-agent-skills/caching@git:20261105.39988c5

Pins git:20261105.39988c5 in mdr.lock. Pin the fingerprint instead.

Designs and diagnoses Redis data structures and atomic operations, application cache keys and invalidation, and HTTP caching. Use for Redis, TTL, cache stampedes, stale data, Cache-Control, Vary, ETag or Nginx proxy_cache changes. Excludes SQL and MongoDB work, which belongs to database.

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

1. Identify the requested outcome and authorized environment from project instructions, callers, configuration and lockfiles. Record server, driver and proxy versions, topology, affected key prefixes or cache zones, and existing access policy. Do not upgrade a dependency or provision a service just to follow documentation.

2. Select only the relevant procedure. Read multiple references when the request crosses layers.

- Read [Redis](references/redis.md) for data structures, TTL, Lua, connections, durability, cluster, ACLs or existing Redis Search behavior.
- Read [application caching](references/application-caching.md) for cache keys, invalidation, concurrent misses, lock ownership, failure behavior or user isolation.
- Read [HTTP caching](references/http-caching.md) for browser, CDN, proxy and Nginx storage, variants, validators or revalidation.

3. Establish the correctness contract before tuning. Trace actual readers and writers, authorization, commit boundaries, source of truth, required freshness and failure behavior. For a stale response, locate the layer that supplied its bytes before changing TTLs or indexes. A cache namespace does not replace authorization.

How to install

The exact contents, by fingerprint

mdr add dayfinggg/openai-codex-agent-skills/caching@sha256:ac8c621572724887

The line at the top of this page pins the label git:20261105.39988c5, 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.
