Highest confirmed finding severity

Medium

3 confirmed security findings require attention.

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.

The skill relies on the external eightctl CLI, which can control an Eight Sleep device after authentication. Markdown-only detections for config paths, homepage metadata, and rate-limit notes were false positives, but mutable installation, credential handling, and device-changing commands require clear safeguards.

Capability review items (8)
Medium
SKILL.md:27
Ruby/shell backtick execution
Use `eightctl` for Eight Sleep pod control. Requires auth.
The backticks are Markdown, not Ruby execution, but this line confirms reliance on the external eightctl command.
Medium
SKILL.md:36
Ruby/shell backtick execution
- `eightctl status`
The backticks are Markdown, but the skill instructs the agent to run the external eightctl status command.
Medium
SKILL.md:37
Ruby/shell backtick execution
- `eightctl on|off`
The backticks are Markdown, but the skill documents external eightctl on and off commands that change device state.
Medium
SKILL.md:38
Ruby/shell backtick execution
- `eightctl temp 20`
The backticks are Markdown, but the skill documents an external eightctl temperature command.
Medium
SKILL.md:42
Ruby/shell backtick execution
- Alarms: `eightctl alarm list|create|dismiss`
The backticks are Markdown, but the skill documents external eightctl alarm commands.
Medium
SKILL.md:43
Ruby/shell backtick execution
- Schedules: `eightctl schedule list|create|update`
The backticks are Markdown, but the skill documents external eightctl schedule commands.
Medium
SKILL.md:44
Ruby/shell backtick execution
- Audio: `eightctl audio state|play|pause`
The backticks are Markdown, but the skill documents external eightctl audio commands.
Medium
SKILL.md:45
Ruby/shell backtick execution
- Base: `eightctl base info|angle`
The backticks are Markdown, but the skill documents external eightctl base commands.

Risk findings

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

Confirmed security concerns (3)

RISK-001 Medium
SKILL.md:14-18
Mutable External Tool Installation
The skill installs github.com/steipete/eightctl/cmd/eightctl@latest, which can resolve to different code over time.
The metadata explicitly declares a Go install target with the @latest version selector.
RISK-002 Medium
SKILL.md:27-32
Sensitive Account Credentials Required
The skill requires Eight Sleep authentication and supports config or environment variables for email and password.
The instructions state that authentication is required and name credential storage mechanisms.
RISK-003 Medium
SKILL.md:36-50
Authenticated Device State Changes
The skill can change temperature, power, alarms, schedules, audio, and base position through an unofficial API.
The command list includes several mutating operations, and the notes state the API is unofficial.

Remediation

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

  1. FIX-001
    Medium
    The installer references a mutable Go module version.
    Pin the eightctl module to a reviewed release and document how users can verify the installed binary.
  2. FIX-002
    Medium
    The skill requires Eight Sleep account credentials through config or environment variables.
    Tell users to protect the config file permissions and never paste credentials into chat transcripts.
  3. FIX-003
    Medium
    Commands can change temperature, alarms, schedules, audio, or base position.
    Require explicit confirmation for every mutating command, not only temperature and alarms.
