action's exact commit (e.g., "uses: ScribeMD/docker-cache@<commit-sha>"); update
the line where the action is referenced so the workflow uses the full commit

cache key generation to include the repository Tiltfile (and any other
image-defining config files) in its hash instead of the broad
`.github/workflows/checks.yml` or the unnecessary `**/Dockerfile*`
pattern—locate where `key: ${{ github.ref_name }}` is defined in the workflow
and append a hash of the Tiltfile (and any specific image config files) to the
key so the cache invalidates when those files change.

🌐 Web query:
What is the full commit SHA currently referenced by the GitHub Action tag ScribeMD/docker-cache@0.5.0?
💡 Result:
The GitHub Action tag ScribeMD/docker-cache@0.5.0 currently points to commit SHA fb28c93772363301b8d0a6072ce850224b73f74e [1][2]. This SHA is shown on GitHub’s tag listing for 0.5.0 (short form fb28c93) [1] and as the full 40-character commit in a workflow that uses uses: ScribeMD/docker-cache@0.5.0 [2].

Pin ScribeMD/docker-cache to the immutable commit SHA.
Using @0.5.0 (a tag) is mutable and introduces supply-chain drift risk; CI behavior can change without code changes. Pin to the commit SHA instead.

ScribeMD/docker-cache action hashFiles support parameters
💡 Result:
ScribeMD/docker-cache does not have any special “hashFiles support” parameter. What it does support is using GitHub Actions expression functions (like hashFiles) yourself when you set the action’s required input key. 1) Supported inputs - key (required): “The cache key to ferry to the official GitHub cache action” [1][2]. This is where you put something like docker-${{ runner.os }}-${{ hashFiles('docker-compose.yaml') }} (shown in the action docs as an example key strategy) [3][4]. - read-only (optional, default: false): If true, disables saving the cache upon cache miss [1][4]. 2) Using hashFiles with this action Example from the action docs: - name: Cache Docker images uses: ScribeMD/docker-cache@0.5.0 with: key: docker-${{ runner.os }}-${{ hashFiles(paths) }} [3][4] The docs also recommend changing the key to a “fast function of your Docker image versions”, giving hashFiles('docker-compose.yaml') as the idea [3][4]. 3) What is NOT supported - restore-keys is not supported by this action [1][4]. The README/action.yaml explicitly says partial cache restoration via restore-keys is not supported due to a “snowball” effect [1][4]. 4) Related behavior notes (for context) - This action caches images (pulled/built) but “does not perform Docker layer caching” [4][3]. If you paste your current workflow snippet (the uses: step and your with: block), I can suggest an exact key expression that matches the files that define which images/tags you pull or build.

Include configuration files in Docker cache key to prevent stale images across branches.
The Docker cache key currently depends only on github.ref_name, allowing images cached on one branch to be reused on another even when Tilt or Kubernetes configurations change. Include the Tiltfile in the cache hash. The pattern **/Dockerfile* is unnecessary (no Dockerfiles exist in this repository). Including .github/workflows/checks.yml in the key is overly broad; focus on files that define which images are deployed.
