Reviewer's GuideAdds a new GitHub Actions workflow that generates a secret in one job and consumes it in a dependent job using a secret-store action, wiring outputs between jobs and masking secrets in logs. Sequence diagram for secret generation and consumption workflowsequenceDiagram

There was a problem hiding this comment.
Hey - I've found 3 issues, and left some high level feedback:
- The
concurrency:key at the end of the file is incomplete and will cause a YAML/Actions parsing error; either remove it or provide a full configuration block (e.g.,concurrency: { group: ..., cancel-in-progress: ... }). - If the secret handle itself is sensitive, consider masking it or avoiding printing it in logs by treating it similarly to the secret value (e.g., using
::add-mask::or not echoing it at all).

## Overall Comments
- The `concurrency:` key at the end of the file is incomplete and will cause a YAML/Actions parsing error; either remove it or provide a full configuration block (e.g., `concurrency: { group: ..., cancel-in-progress: ... }`).
- If the secret handle itself is sensitive, consider masking it or avoiding printing it in logs by treating it similarly to the secret value (e.g., using `::add-mask::` or not echoing it at all).

**🚨 suggestion (security):** Use a stronger source of randomness for generated secrets
`$RANDOM` has only 0–32767 possible values and is not cryptographically secure. If this is used as a secret/token, please switch to a higher‑entropy, crypto‑secure source (e.g., `head -c 32 /dev/urandom | base64` or `openssl rand -hex 32`) to avoid predictability.

**🚨 suggestion (security):** Avoid echoing secrets even when masked in logs
Even with masking, it’s safer not to print secrets at all, as masking can fail in edge cases (e.g., partial matches, formatting). If this is only for debugging, consider removing the echo or guarding it behind a debug flag.
```suggestion
SECRET_HANDLE="${{ needs.secret-generator.outputs.handle }}"

**issue (bug_risk):** Fix the empty `concurrency` configuration to avoid workflow parse/runtime issues
`concurrency:` is currently empty, which produces invalid or unintended workflow YAML. If you want concurrency controls, specify a group (and optionally `cancel-in-progress`), for example:
```yaml
group: ${{ github.workflow }}-${{ github.ref }}
cancel-in-progress: true
```
If not using concurrency, remove the `concurrency:` key to avoid misconfiguration.
