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.

Static analysis detected 534 potential issues, but after human evaluation, all findings are false positives. The skill is a legitimate API client for the Pexo AI video service. External commands detected in documentation files are showing command syntax, not actual execution. Network access is limited to pexo.ai API endpoints. Environment access is for API authentication, not credential exfiltration. The skill uses shell scripts to wrap API calls, which is standard for CLI tools.

Limitations

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

Evidence chain

Capability review items (4)
Medium
references/SETUP-CHECKLIST.md:9references/TROUBLESHOOTING.md:5SKILL.md:30
Shell Command Patterns in Documentation
Static scanner flagged shell command patterns (backticks, $() syntax) in markdown reference files and SKILL.md. These are documentation showing command syntax for educational purposes, not actual code execution. The skill executes pre-written scripts via pexo-*.sh wrappers that call the Pexo API.
All shell command patterns appear in documentation context or legitimate script wrappers that make API calls to pexo.ai - no user input injection vectors exist
Medium
scripts/_common.sh:239SKILL.md:9-10
Network Access to External API
Skill makes network requests to pexo.ai API endpoints. This is the intended functionality of the video creation service, not data exfiltration.
Network requests are to the legitimate Pexo API service at pexo.ai for video creation - documented and expected behavior
Medium
scripts/_common.sh:21-22SKILL.md:13
Environment Variable Access for API Authentication
Skill reads PEXO_API_KEY and PEXO_BASE_URL environment variables for API authentication. This is standard API client behavior, not credential exfiltration.
Environment variables are used only for authenticating with the Pexo API - credentials stay local and are sent only to the intended service
Low
scripts/_common.sh:7
Configuration File Access
Skill reads config from ~/.pexo/config directory. This is the intended configuration location for the Pexo tool.
Standard configuration file location for the Pexo tool - documented in SKILL.md prerequisites section

Risk findings

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

Confirmed security concerns (2)

RISK-001 Low
scripts/pexo-doctor.sh:157scripts/pexo-doctor.sh:162
System Diagnostics in Doctor Script
pexo-doctor.sh contains system reconnaissance commands (uname, date, etc.) for diagnostic purposes. This is legitimate troubleshooting functionality as documented in SKILL.md.
Diagnostic commands are for user-initiated troubleshooting, not stealth reconnaissance - explicitly mentioned in skill documentation
RISK-002 Low
scripts/pexo-chat.sh:127
Timestamp Generation Pattern
Scanner flagged 'date +%s000' as weak crypto, but this is simply generating Unix timestamps for API request payloads, not cryptographic operations.
Unix timestamps for API request bodies are standard practice, not cryptographic operations - no actual crypto weakness present
