A common culprit for cache misses is the environment. If your build script pulls in a timestamp, a random seed, or a local file path (e.g., /Users/john/project vs /Users/jane/project ), the cache will treat them as different actions. 3. Verbose Logging

Two different machines running the exact same code produce different output hashes, leading to "cache poisoning." How to Debug the Cache: Common Strategies debug-action-cache

If the source code, environment variables, and toolchains remain identical, the system skips the work and pulls the result from the cache. When this breaks, your CI costs spike and developer productivity plummets. Why Use debug-action-cache ? A common culprit for cache misses is the environment

Before diving into debugging, it’s essential to understand what we’re fixing. Action caching stores the outputs of specific build steps (actions) based on their inputs. The logic is simple: Verbose Logging Two different machines running the exact

While different tools have different specific commands, the process of "debugging the action cache" generally follows these steps: 1. Inspecting Input Digests

You changed one line of a README file, but the entire C++ library is recompiling. Why did the hash change?
