Highest confirmed finding severity

Medium

3 confirmed security findings require attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

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

Security evaluation confirms this is a safe skill. Static findings were analyzed and determined to be false positives or legitimate functionality. The skill uses subprocess for git operations with hardcoded arguments (no injection risk), has built-in secret detection for security, and operates only within the user's project directory.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Risk findings

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

Confirmed security concerns (3)

RISK-001 Medium
scripts/create_handoff.py:55-88scripts/check_staleness.py:85-125
Subprocess Usage for Git Commands
Scripts use subprocess.run to execute git commands. Arguments are hardcoded strings, not user input. No command injection risk exists. Usage is limited to read-only git operations (status, log, diff) and project directory file operations.
Direct code inspection confirms subprocess arguments are hardcoded string arrays like ['git', 'rev-parse', '--git-dir'] with no user input concatenation
RISK-002 Medium
scripts/validate_handoff.py:28-29scripts/validate_handoff.py:96-103
Secret Detection Patterns Flagged as Crypto
The static scanner flagged regex patterns for detecting private keys and secrets as 'weak cryptographic algorithm'. These are intentional security patterns in validate_handoff.py that scan handoff documents for accidental secret exposure before finalization.
Pattern matching in validate_handoff.py is explicitly for detecting secrets in handoff documents before they are shared - a security feature, not a vulnerability
RISK-003 Low
scripts/create_handoff.py:184-186scripts/list_handoffs.py:69-72
Filesystem Access in Project Directory
Scripts read and write files within .claude/handoffs/ directory. This is intentional project-scoped storage with no system-level access.
File operations are confined to project-relative path .claude/handoffs/ with no traversal outside project bounds
