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.

Installation context

Historical evidence

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

Open current Skill page

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

Seven static findings are confirmed because the skill documents npx, pip, brew, or apt-get commands that can execute code or modify the host. The remaining findings are false positives from Markdown formatting, standard cache paths, a relative documentation link, or non-reconnaissance prose. No prompt injection, credential exfiltration, or hidden malicious intent was found in SKILL.md.

Capability review items (7)
Medium
SKILL.md:14-18
Ruby/shell backtick execution
```bash
The bash example instructs running npx hyperframes tts, which executes external Node package code and writes media output. This is expected functionality but requires user confirmation.
Medium
SKILL.md:36-39
Ruby/shell backtick execution
```bash
The bash example instructs running npx hyperframes tts for multilingual speech generation. It executes external CLI code and should be run only with trusted inputs.
Medium
SKILL.md:41
Ruby/shell backtick execution
Use `--lang` only to override auto-detection (stylized accents). Valid codes: `en-us`, `en-gb`, `es`
The requirements text includes brew install espeak-ng and apt-get install espeak-ng, which modify the host system. This setup path is legitimate but needs explicit approval.
Medium
SKILL.md:56
Ruby/shell backtick execution
Python 3.8+ with `kokoro-onnx` and `soundfile` (`pip install kokoro-onnx soundfile`). Model download
The requirements text includes pip install kokoro-onnx soundfile, which changes the Python environment and downloads packages. This is expected setup behavior but security-relevant.
Medium
SKILL.md:62-68
Ruby/shell backtick execution
```bash
The bash examples instruct running npx hyperframes transcribe on media and subtitle files. This executes external CLI code against local user-selected inputs.
Medium
SKILL.md:107-115
Ruby/shell backtick execution
```bash
The bash examples instruct running npx hyperframes remove-background and writing generated media files. This executes external CLI code and should be user-confirmed.
Medium
SKILL.md:238-241
Ruby/shell backtick execution
```bash
The bash workflow chains npx hyperframes tts and npx hyperframes transcribe. It executes external CLI commands and writes generated audio and transcript files.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    External command execution through HyperFrames CLI examples.
    Require explicit user confirmation before running commands and show input paths, output paths, and resolved package sources.
  2. FIX-002
    Medium
    Package manager installation guidance for Python and system dependencies.
    Prefer pinned versions and documented prerequisites; avoid automatic brew, apt-get, or pip installs.
  3. FIX-003
    Low
    Large model downloads and cache writes are part of normal operation.
    Publish model source, checksum, size, and cache location so users can verify downloads and manage disk use.

Analysis state: Complete

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

JSON report CITATION.cff SARIF 2.1.0 Signed installation manifest

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
