1 high severity finding. You should review these findings carefully before considering using this skill.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill documentation includes an explicit example that passes a password on the command line ("--protect your-password"), which encourages embedding a secret verbatim in generated commands and therefore requires the LLM to handle/output secret values directly.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
At runtime, the workflow path `scripts/xlsx_read.py` (modes `--json/--csv/--formulas/--notes/--names/--sheets`) loads an input `.xlsx` and ingests free text from worksheet cell values and comments/notes (including any outsider-authored strings embedded in the workbook).
