Installation context

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

All static findings are false positives from documentation and shell scripts. The skill uses legitimate bash commands for API calls to a known video service (pexo.ai). External commands execute standard tools (curl, jq) with hardcoded arguments - no user input injection. Environment variables access only reads configuration (API keys) for the service. File operations are limited to config directories in user home. This is a legitimate client library for video creation, not malware.

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.

Capability review items (2)

Low

scripts/_common.sh:21-33 SKILL.md:13

Environment Variable Access for Configuration

Scripts read PEXO_API_KEY and PEXO_BASE_URL from environment or config file. This is the intended behavior for API client configuration. Credentials are used only for authenticated requests to pexo.ai service. No evidence of exfiltration.

Legitimate credential usage for API authentication - standard pattern for client libraries.

Low

scripts/_common.sh:3-8 scripts/pexo-asset-get.sh:13

Filesystem Access to Config Directories

Scripts access ~/.pexo/config and ~/.pexo/tmp for configuration and temporary storage. This is the documented behavior for storing user settings. No access to sensitive system files or directories outside user's home.

Standard application config storage pattern - no sensitive file access outside app directory.

Risk findings

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

Confirmed security concerns (2)

RISK-001 Medium

scripts/pexo-asset-get.sh:10 scripts/pexo-chat.sh:10

MD5 Hash Usage in Scripts

Several shell scripts use MD5 hashing (md5sum) for file integrity checks. While not actively exploitable, MD5 is cryptographically weak. This is a false positive - MD5 is used here for non-security file verification, not cryptographic purposes.

Pattern detected but legitimate use - MD5 used for file integrity checks, not security. No exploitability in this context.

RISK-002 Low

references/SETUP-CHECKLIST.md:9-15 references/TROUBLESHOOTING.md:5-7

Shell Command Execution in Documentation

Documentation files (SETUP-CHECKLIST.md, TROUBLESHOOTING.md) contain code examples with backticks and command substitution. These are instructional examples, not executable code. This is a false positive - documentation showing users how to run commands.

False positive - these are markdown code examples in documentation, not executable code.
