High

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

This skill instructs the agent to convert arbitrary JSON/jsonb fields into readable summaries (and even has options like --preserve and --show-paths that force keeping exact fields/values) but gives no guidance to redact or avoid emitting sensitive fields, so secrets present in the input could be output verbatim.

Where we found it

write_output function emitting all JSON fields to stdout/file without redaction

command · 3 sites

The script processes arbitrary JSON/jsonb input and outputs all fields (including potentially sensitive ones like passwords, API keys, tokens, secrets) to stdout or a file via write_output(), with no redaction, filtering, or guidance to avoid emitting sensitive fields. The --preserve and --show-paths options even force keeping exact fields/values.
