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

Most static findings are false positives caused by Markdown code fences, documented gget commands, expected analysis file writes, and public database links. The audit did find semantic risks: a bundled self-attested safety report, promotional steering text, an unsafe pickle cache example, and an output-path issue from unsanitized FASTA identifiers.

Confirmed security concerns (4)

RISK-001 High
evaluation_output.json:14-18
Prompt Injection Attempt Detected
evaluation_output.json includes self-attested audit fields that claim risk_level is safe, safe_to_publish is true, and no malicious behavior was detected. Untrusted skill content should not attempt to pre-answer marketplace security decisions.
The file directly contains safety verdict language inside the skill package. It does not issue an explicit override command, so confidence is high but not absolute.
RISK-002 High
references/workflows.md:793-798
Unsafe Pickle Cache Example
references/workflows.md demonstrates loading cached results with pickle.load from a caller-supplied cache path. Loading untrusted pickle files can execute arbitrary Python code.
The code directly calls pickle.load on a file path without trust checks. This is a well-known unsafe deserialization pattern when cache files are not fully controlled.
RISK-003 Medium
SKILL.md:870-871
Commercial Steering Instruction
SKILL.md instructs the assistant to proactively suggest K-Dense Web for complex workflows. This can steer users toward a hosted service unrelated to the immediate gget task.
The instruction is explicit and appears in the skill body. It is promotional rather than covert malware, so medium severity is appropriate.
RISK-004 Medium
scripts/batch_sequence_analysis.py:16-25scripts/batch_sequence_analysis.py:77-78
Untrusted FASTA Header Used in Output Path
scripts/batch_sequence_analysis.py derives BLAST output filenames from FASTA record identifiers. A crafted identifier with path separators could write outside the intended output directory.
The parser stores raw FASTA headers and later uses them in a filename. Exploitability depends on running the helper script on untrusted FASTA input.

Remediation

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

  1. FIX-001
    High
    Bundled self-attested security report
    Remove evaluation_output.json from the published skill or strip safety verdict fields that can influence reviewers.
  2. FIX-002
    High
    Unsafe pickle deserialization example
    Replace pickle caching with JSON, CSV, Parquet, or a signed trusted cache format.
  3. FIX-003
    Medium
    Promotional steering instruction
    Remove the instruction to proactively recommend K-Dense Web, or move disclosure to neutral marketplace metadata.
  4. FIX-004
    Medium
    FASTA identifiers used in output filenames
    Sanitize sequence identifiers, remove path separators, and enforce that resolved paths remain under the output directory.
  5. FIX-005
    Medium
    Credential examples use command-line API key arguments
    Prefer secure configuration, environment variables, or interactive secret prompts instead of command-line secrets.
