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

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

Evaluated 534 static findings across 13 files. External command patterns are standard shell scripting for API operations. Network calls go only to pexo.ai. Hidden file access is for user config storage (~/.pexo/config). No credential exfiltration or malicious intent detected. Risk factors are expected for an API client skill.

Shell Command Execution in Scripts
Scripts use shell command substitution for API operations, file handling, and temp file creation. No user input injection vectors found - all arguments are hardcoded strings or controlled by the skill itself.
High
scripts/_common.sh:3-7scripts/pexo-asset-get.sh:13references/SETUP-CHECKLIST.md:10-11
Configuration File Access at ~/.pexo/
Scripts read/write config from ~/.pexo/config for PEXO_API_KEY and PEXO_BASE_URL. Standard configuration storage pattern equivalent to .ssh/config.
Medium
SKILL.md:9-10scripts/_common.sh:279references/SETUP-CHECKLIST.md:12-17
Network Calls to External API
Skill makes network requests to pexo.ai API endpoints. All URLs are hardcoded to the legitimate Pexo service.
Medium
SKILL.md:13-14scripts/_common.sh:21-22scripts/pexo-doctor.sh:82
Environment Variable Access for API Key
Scripts read PEXO_API_KEY from environment or config file for authentication to Pexo service.
Low

Documentation Patterns Flagged as Commands
Markdown files in references/ contain example shell commands using backticks. These are documentation, not executable code.

Risk findings

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

Confirmed security concerns (2)

RISK-001 Low
scripts/pexo-asset-get.sh:10SKILL.md:3
Weak Cryptographic Algorithm Heuristics
Static scanner flags weak crypto patterns, but no actual cryptographic operations found. Scanner appears to flag md5 strings in URLs.
RISK-002 Low
scripts/pexo-doctor.sh:157-162references/TROUBLESHOOTING.md:5-7
System Reconnaissance Patterns
Diagnostic scripts check for installed tools (curl, jq, file) and network connectivity. Standard practice for CLI tools.
