             - **Target**: `file_io`
             - **Crash File**: `$CRASH_FILE`
-            - **Total Crashes**: $CRASH_COUNT
             - **Branch**: $BRANCH
             - **Commit**: $COMMIT

+            - **Crash Artifact**: $ARTIFACT_URL
 
             ### Reproduction
 
-            1. Download the crash artifact from the workflow run:
-               - **Workflow run**: $WORKFLOW_RUN
-               - Look for the artifact named `io-fuzzing-crash-artifacts` at the bottom of the workflow run page
-               - Download and extract the zip file
+            1. Download the crash artifact:
+               - **Direct download**: $ARTIFACT_URL
+               - Or find `io-fuzzing-crash-artifacts` at: $WORKFLOW_RUN
+               - Extract the zip file
 
             2. Reproduce locally:
             ```bash
             # The artifact contains file_io/$CRASH_FILE
-            cargo +nightly fuzz run file_io file_io/$CRASH_FILE
+            cargo +nightly fuzz run --sanitizer=none file_io file_io/$CRASH_FILE
             ```
 
             3. Get full backtrace:
             ```bash
-            RUST_BACKTRACE=full cargo +nightly fuzz run file_io file_io/$CRASH_FILE
+            RUST_BACKTRACE=full cargo +nightly fuzz run --sanitizer=none file_io file_io/$CRASH_FILE
