Installation context

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.

Static analysis correctly identified a pipe-to-shell installer pattern and real network use, but most Ruby backtick and weak-cryptography alerts are Markdown false positives. The skill appears legitimate and purpose-built for remote Remotion rendering, yet it should publish with warnings about executing installer scripts, sending TSX and props to inference.sh, and the broad infsh CLI allowance.

SKILL.md:9-11SKILL.md:207-209
Hardcoded external URLs are expected service links
The hardcoded URL findings are true positives for network references, but they point to the documented service, image asset, and official docs. No credential exfiltration or hidden callback endpoint was found.
The URLs are visible documentation and asset links. I did not find evidence that secrets are sent to an unrelated endpoint.

Risk findings

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

Confirmed security concerns (3)

RISK-001 Medium
SKILL.md:17
Pipe-to-shell CLI installation instruction
The static pipe-to-shell finding at SKILL.md line 17 is a true positive for a dangerous install pattern. It fetches a remote shell script and executes it immediately, which creates supply-chain risk even though line 29 documents checksum verification.
The command directly pipes a remote URL into sh. The surrounding install note suggests legitimate intent, so this is risky but not confirmed malicious.
RISK-002 Medium
SKILL.md:4
Broad inference.sh CLI command allowance
The skill allows Bash(infsh *), which permits any inference.sh CLI subcommand rather than only the remotion-render app. This is broader than required and can run other remote app operations under the user account.
The allowlist is explicit and semantically broader than the documented render workflow. Legitimate use is likely, but the scope should be narrowed.
RISK-003 Medium
SKILL.md:20-26SKILL.md:35-42SKILL.md:136-179
Remote rendering receives user TSX and props
The render workflow sends user-provided TSX code and optional props to inference.sh for processing. This is the intended function, but users may expose proprietary code, media references, or sensitive data in props.
The examples and input schema show code and props sent to a named remote app. This is expected behavior, but it is a clear privacy boundary.

Analysis metadata

Audit model: codex

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:3SKILL.md:15SKILL.md:33SKILL.md:46-48
Markdown syntax caused static-analysis false positives
The Ruby backtick execution findings are false positives caused by Markdown fences, inline code, and example commands. The weak cryptography findings at lines 3 and 33 were not confirmed as real cryptographic use.
The cited lines are frontmatter text, Markdown code fences, a table header, or import examples. There is no Ruby execution or weak hash call in those locations.
