Sometimes a cache restores successfully but contains the wrong files. How to inspect its contents without fully running a job? Two methods:
provides a dedicated management interface to view and delete active caches. Navigation : Navigate to your repository on GitHub. Go to (left sidebar under "Management"). What to Look For
Use this UI to:
Choosing how to structure your cache keys determines how often your workflows hit or miss. Cache Strategy Best Used For Core OS dependencies, system-wide runtimes. High reuse across different feature branches. Prone to accidental pollution and bloat. Matrix Cache Multi-version testing (Node 18 vs Node 20). Completely isolates different execution environments. Multiplies storage usage across the repository. Branch-Isolated Feature-specific feature builds. Prevents main branch code from being overwritten. Fresh branches suffer a slow first build. 💡 Pro Tips for Maintaining High Cache Hit Rates debug-action-cache

Build tools frequently use environment variables to configure compilers. If a cloud runner injects a fluctuating variable (like a unique RUNNER_TRACKING_ID ), the cache engine assumes the build environment has changed and invalidates the previous cache. 3. Non-Deterministic Build Outputs

: The runner found a cache matching your exact key. No assets were downloaded from the internet.

Warning: These tokens are short-lived and sensitive. Never print them in logs or share them.

This forces the cache engine to print exact compression statistics, network download speeds, and key-matching logic directly into the console. Step 2: Audit Cache Key Hashes
