Is Srt Whiteboard Animation safe?
- Python shell/command execution
- Python filesystem read
What to do: Nothing here argues against installing it. Grant the capabilities it lists only if you expect the tool to need them.
Srt Whiteboard Animation is an agent skill analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators. It can: filesystem read and shell execution — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).

Automated static-analysis result. It can contain false positives and false negatives, and is not a claim about the intent of Srt Whiteboard Animation's authors. Report a false positive.
Behavioral traits
How this component maps to the CSA agentic threat model. Descriptive — it never affects the risk score.
Findings (2)
The component can run operating-system commands or spawn processes.
res = subprocess.run(
[ffmpeg, "-y", "-loglevel", "error", "-f", "concat", "-safe", "0",
"-i", str(list_path), "-c", "copy", str(output)],
capture_output=True, text=True,
)res = subprocess.run(
[ffmpeg, "-y", "-loglevel", "error", "-f", "concat", "-safe", "0",
"-i", str(list_path), "-c:v", "libx264", "-crf", "20",
"-pix_fmt", "yuv420p", "-vf", "scale='trunc(iw/2)*2':'trun …probe = subprocess.run(
[str(py), "-c", f"import {import_name}"],
capture_output=True,
)res = subprocess.run(
[str(py), "-m", "pip", "install", "--quiet", *packages],
capture_output=True,
text=True,
)res = subprocess.run(cmd, capture_output=True, text=True)
Why it matters: Powerful and often legitimate — confirm the commands aren't built from untrusted input.
Fix: Confirm the command and its arguments are fully controlled and not derived from untrusted input; avoid shell=True.
The component reads files from disk.
raw = Path(args.srt).read_text(encoding="utf-8-sig")
data = json.loads(Path(annotation_path).read_text(encoding="utf-8"))
annotation = json.loads(Path(args.annotation).read_text(encoding="utf-8"))
Why it matters: Usually legitimate, but worth confirming it can't be steered into reading sensitive files.
Fix: Confirm which files are read and that paths cannot be influenced by untrusted input to reach sensitive locations.
