Implement caching with the Symfony Cache component; configure pools, use tags for invalidation, prevent stampede.
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
# Symfony Cache (Symfony) ## Use when - Caching expensive reads: repository results, computed values, third-party responses. - Choosing or configuring a pool and its adapter (filesystem, Redis, APCu, chained). - Invalidating by tag rather than clearing everything. - A hot key expires under load and every request recomputes it at once. - Adding HTTP cache headers, a cache warmer, or clearing pools on deploy. ## Default workflow 1. Identify what is recomputed and how often, and whether it can go stale. 2. Pick the pool and adapter for the access pattern and the deployment shape. 3. Read through `CacheInterface::get()` with an explicit expiry. 4. Tag every entry by the data it derives from, and invalidate by tag on write. 5. Enable early expiration on keys whose recomputation is expensive. ## Guardrails - Set an expiry on every entry. An entry without one never leaves the pool. - Never put user input in a cache key unhashed, and never put secrets in one. - Invalidate by tag, not by clearing the pool: a full clear is a cold start. - A cached value is stale by definition. Do not cache what must be exact. …

How to install
mdr add dev-toolings/superpowers-symfony/symfony-cache@sha256:9e68aa25f4ebd2ffThe line at the top of this page pins the label git:20261005.042befb, 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.
