The static analyzer detected 534 patterns across 13 files (2110 lines) with a risk score of 100/100. After semantic evaluation, all findings are confirmed as FALSE POSITIVES. The skill is a legitimate CLI client for the Pexo AI video platform. Shell commands (curl, jq, mktemp, stat) are standard CLI tooling. Network requests target only the configured PEXO_BASE_URL (default: pexo.ai). File access is limited to the skill's own config directory (~/.pexo/config) and temp files. Environment variable access reads only documented PEXO_API_KEY and PEXO_BASE_URL. No prompt injection, credential exfiltration, data exfiltration, or malicious behavior was detected. The skill acts as a relay between the user and Pexo's backend API.

Capability review items (3)
Medium
scripts/_common.sh:223-225scripts/pexo-upload.sh:52-55
Shell scripts execute external commands extensively
The skill uses curl, jq, mktemp, stat, basename, sed, awk, and other shell utilities across 349 locations. These are standard CLI tools used for HTTP requests, JSON processing, and file operations. All arguments are either hardcoded or derived from user-provided inputs that are validated locally before use. This is expected behavior for a shell-based API client.
Pattern confirmed through full code review. All shell commands serve legitimate CLI client purposes with no injection vectors.
Medium
scripts/_common.sh:3-7
Shell scripts source configuration from hidden directory
Scripts source ~/.pexo/config which sets PEXO_BASE_URL and PEXO_API_KEY. This is the documented configuration mechanism. The config file path is configurable via PEXO_CONFIG environment variable. This is standard practice for CLI tool configuration.
Confirmed legitimate config pattern. Path is documented and configurable. No evidence of unauthorized file access.
Low
scripts/_common.sh:223-225
Temporary file creation in shell scripts
Scripts create temporary files using mktemp for HTTP response bodies, headers, and error output. Files are cleaned up after use with rm -f. This is standard practice for shell-based HTTP clients.
mktemp is the safe way to create temp files. Cleanup with rm -f is present. No temp file leakage detected.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
scripts/pexo-doctor.sh:32-37
System information queries in diagnostic script
pexo-doctor.sh runs command -v and --version checks to verify curl, jq, and file are installed. This is standard environment validation for a CLI tool dependency checker.
command -v and --version are standard dependency checks. No sensitive system information is collected.

Analysis metadata

Audit model: claude

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Static false positives ignored (1)
Low
SKILL.md:9-10scripts/_common.sh:279
Hardcoded URLs in documentation and scripts
Multiple files contain hardcoded references to https://pexo.ai and related endpoints. These are the service's own URLs, documented as the default PEXO_BASE_URL. The base URL is configurable, allowing users to override the default.
URLs point to the service's own documented domain. PEXO_BASE_URL is configurable, mitigating lock-in risk.
