Severity Finding Location
Info
Broad file write capabilities in unittest-completer
The unittest-completer sub-skill has Write/Edit/MultiEdit permissions to create and modify test files. This is necessary for its auto-completion feature but grants broader file write access than the testing domain alone.
allowed-tools: Read, Edit, MultiEdit, Write, Bash, Glob, Grep, TaskCreate, TaskUpdate, TaskList
→ This is legitimate behavior for a test auto-completion tool. Test files are created in the project's designated test directory ($PATH/$testDir/), not arbitrary locations.
 sub-skills/unittest-completer/SKILL.md:5
Info
Configuration isolation using project hash
The skill stores project-specific configuration in .temp/projects/<hash>/ using MD5 hash of project root. This prevents configuration conflicts between multiple projects.
const projectDir = path.join(skillRoot, '.temp', 'projects', hash);
→ Security-positive design: isolates per-project config and uses .temp/ (outside git) for temporary data.
 scripts/resolve-project.cjs:67
Info
Legitimate Jest command execution
The skill uses execSync to run `npx jest` commands for testing. This is expected behavior for a unit testing tool.
execSync(testCommand, { cwd: projectRoot, encoding: 'utf-8', ... })
→ No action needed - this is the core functionality of the skill.

Security Positives

✓ Comprehensive documentation with SKILL.md files for main skill and all sub-skills
✓ Project configuration isolation prevents cross-project data leakage
✓ Uses .temp/ directory (outside git) for temporary files and coverage reports
✓ No credential harvesting, sensitive path access, or data exfiltration
✓ No base64-encoded payloads, hidden instructions, or obfuscated code
✓ Clear error handling with specific error types (config_error, env_error, test_error)
✓ Legitimate subprocess usage for running Jest tests - documented and necessary
✓ Jest configuration parsing uses regex extraction - no unsafe eval()
✓ No external network requests except `npx jest --version` for version detection
