Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

All 534 static analysis findings are FALSE POSITIVES. This is a legitimate CLI tool that integrates with the Pexo AI video API. The external commands, network calls, filesystem access, and env var reads are all expected behaviors for a CLI tool that calls an authenticated REST API. No evidence of malicious intent, data exfiltration, credential theft, or obfuscation was found. The scripts are transparent, well-structured, and use safe coding patterns (set -euo pipefail, temp file cleanup, credential masking in output). Safe to publish with documentation about access patterns.

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 (5)

Low

scripts/_common.sh:223-225 scripts/pexo-chat.sh:48-155

Shell command execution in bash scripts

349 instances of shell commands (curl, jq, mktemp, sed, awk) flagged as external_commands. All are standard CLI tool operations with hardcoded or variable-controlled arguments. No user-supplied command injection vector exists. These are expected for a shell-based API client.

Low

scripts/_common.sh:279 scripts/pexo-doctor.sh:81

Network calls to pexo.ai API

27 instances of hardcoded URLs and network operations. All URLs point to pexo.ai (the legitimate service being integrated) or its CDN (aliyuncs.com). No data exfiltration to unknown endpoints. Expected for an API-integrated tool.

Low

scripts/_common.sh:3-7 scripts/pexo-doctor.sh:71-80

Filesystem access (config and temp files)

79 instances flagged for filesystem access. Scripts read ~/.pexo/config (own config file), create temp files via mktemp with proper cleanup, and access /dev/null for output suppression. All operations are transparent and expected for a CLI tool that needs configuration and temporary storage.

Low

scripts/_common.sh:21-22 scripts/pexo-doctor.sh:96-99

Environment variable access for API credentials

25 instances of env_access flagged. Scripts access PEXO_API_KEY and PEXO_BASE_URL which are documented required environment variables. Credentials are used only for Bearer token authentication to pexo.ai API. The pexo-doctor.sh script includes a mask_secret function that safely masks the key when displaying it in output.

Low

scripts/_common.sh:21-279

Heuristic: Dangerous combination of code+network+credentials

Static analyzer flagged the combination of shell execution, network calls, and credential access as suspicious. This combination is NECESSARY for any CLI tool that integrates with an authenticated REST API. All network calls target pexo.ai only. No evidence of exfiltration or misuse.

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 (2)

Low

scripts/pexo-doctor.sh:17 scripts/pexo-doctor.sh:117

False positive: Weak cryptographic algorithm

Static analyzer flagged sk- prefix checks and timestamp commands as weak cryptographic algorithms. Scripts check for sk- prefix as basic API key format validation (not cryptography). Date +%s000 generates timestamps for API requests. Neither is a cryptographic operation.

Low

SKILL.md:43

False positive: Windows SAM database reference

Static analyzer flagged SKILL.md line 43 as referencing the Windows SAM database. Line 43 contains the text 'This is non-negotiable.' (part of the language matching instruction). No actual SAM database reference exists. Static analyzer pattern-matching error.
