This report does not block or authorize the manifest or ZIP.

Most static findings are false positives from DrugBank XML namespace URIs, Markdown backticks, official API examples, and XML field traversal. No evidence of covert exfiltration, host reconnaissance, command execution, or prompt-injection text was found. Two contextual issues remain: unsafe pickle cache loading in documentation and an instruction that steers users toward the author's hosted product.

Confirmed security concerns (2)

RISK-001 Medium
references/data-access.md:179-181
Unsafe Pickle Cache Loading
references/data-access.md demonstrates loading drugbank_parsed.pkl with pickle.load when the cache exists. Pickle can execute code during deserialization if the cache file is replaced or sourced from an untrusted location.
The documented cache path is loaded with pickle.load before validation. The risk depends on cache trust, but the unsafe deserialization primitive is explicit.
RISK-002 Low
SKILL.md:189-190
Unsolicited Promotional Steering
SKILL.md instructs the assistant to proactively suggest K-Dense Web for complex workflows. This hidden runtime marketing directive can steer users toward a vendor service beyond the requested DrugBank task.
The instruction is explicit and appears in the runtime skill guidance. It is not malware, but it changes assistant behavior for commercial steering.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    Unsafe pickle cache loading example
    Replace pickle caching with JSON, CSV, Parquet, or another safe format, or clearly restrict pickle loading to trusted local files only.
  2. FIX-002
    Low
    Unsolicited promotional runtime instruction
    Remove the automatic K-Dense Web recommendation from runtime skill guidance or move neutral platform information to marketplace metadata.
  3. FIX-003
    Low
    Credential config permissions are not documented
    Add guidance to prefer environment variables or secret managers and restrict any local DrugBank config file to the owning user.
