Most static findings are false positives caused by Markdown code fences, inline code, metadata URLs, and fixed relative documentation links. One real medium-risk issue remains: the skill instructs the agent to run a local ledger command with user-controlled campaign data. A semantic review also found that saved filenames should sanitize campaign names before writing to memory.

SKILL.md:60
Ruby/shell backtick execution
5. **Snapshot to the ledger.** Record baseline and candidate signals so the delta is computed, not e
Line 60 instructs the agent to run a local python3 ledger command with a user-controlled campaign placeholder. This is legitimate tooling, but it creates command-injection and unsafe-argument risk unless arguments are passed without shell interpolation.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:69
User-Controlled Filename Requires Sanitization
Line 69 tells the agent to save results using a filename that includes the campaign name. Because the campaign name is user-controlled, path separators or special characters could change the write target unless sanitized.
The save path is fixed, but the filename pattern includes a user-derived campaign field. The risk depends on host filename handling, so confidence is high enough to require mitigation but not critical.

Remediation

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

  1. FIX-001
    Medium
    Shell-style ledger command uses user-controlled campaign input.
    Replace the shell example with a structured tool call, or require quoting and argument-array execution without shell interpolation.
  2. FIX-002
    Medium
    Saved readback filename includes a campaign name from user input.
    Convert campaign names to safe slugs and reject path separators before writing under memory/ad/paid-measurement-loop/.
  3. FIX-003
    Low
    Relative Markdown links resemble traversal patterns to scanners.
    Clarify that reference links are documentation-only, or use repository-root reference notation where the marketplace supports it.
