• Outcome: Review
• Latest audit: Oct 21, 2026 · 3:03 AM UTC
• Version: 0.2.4

Overview

This skill needs review because it requests account permissions beyond making silent videos, including managing voices.

Prefer a version with permissions limited to video work. If installing, review the shared Beatra authorization, use only photos approved for external processing, and confirm the quoted batch cost. Installation and system details are reported periodically. Check other Beatra skills before uninstalling; the Beatra Console provides direct credential revocation.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Findings (31)

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 99% confidence

Finding

Paid video generation is explicitly disclosed and confirmation-gated, so wallet spending is not inherently inconsistent with this workflow. However, the reported music, speech, voice-write, and broadly shared credential permissions exceed a silent photo-to-video task and could expand the consequences of credential theft or unauthorized tool invocation; the implementation claims cannot be independently verified from SKILL.md alone.

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence

Finding

The supplied chunk performs no photo processing or clip generation. Although uninstall support can be legitimate package maintenance, this code manages shared device authorization and deletes cross-skill state—substantive capabilities not represented by the narrowly described photo-to-clip purpose. It conservatively preserves the connection when other skills remain or inventory is uncertain, but those safeguards do not eliminate the description–behavior mismatch. This finding does not imply malicious intent.

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 96% confidence

Finding

The reported automatic registration transmits installation and environment metadata beyond the photo-processing inputs, creating a privacy exposure if those fields are unnecessary or not clearly disclosed before transmission. An unrestricted tool dispatcher also increases exposure when paired with excessive credential scopes, although a generic dispatcher is not inherently an authorization bypass; the referenced registration documentation and implementation were not supplied for verification.

When `scripts/uninstall.py` decides this is the last Beatra skill on the
computer, it first asks Beatra to revoke the device credential when one is
stored. If Beatra refuses, it changes nothing so the run can be repeated.
Otherwise it unlinks exactly these names in `~/.beatra/`: `credentials.json`,
`installation.json`, `host.json`, `skills.json`, `registrations.json`,

# Updates and security

Since the October 2026 releases, Beatra Skill packages contain no self-updater.
Earlier releases could replace their own files from Beatra's CDN; that code has
been removed. Updates now come only from the store or tool you installed the
Skill from.

• Confidence: 96% confidence

Finding

L03-L20 specify an automatic registration call that reports a stable installation reference, installation source, network-route information, and runtime facts on first use and periodically thereafter. This is distribution analytics, as explicitly described at L23-L24, rather than an obvious requirement for turning authorized event photos into clips; the manifest does not disclose this additional behavior.

MCP server referenced without pinned version: 'npx skills'.

Medium

• Category: MCP Rug Pull
• Confidence: 84% confidence

Finding

The documented project-update command invokes an unpinned skills package through npx, which can fetch and execute the currently resolved package if it is not available locally. A compromised package release could execute code with the caller's permissions; this is a conditional supply-chain risk in manual update guidance, not an unpinned MCP server or automatic execution.

MCP server referenced without pinned version: 'npx skills'.

Medium

• Category: MCP Rug Pull
• Confidence: 84% confidence

Finding

The global-update variant repeats the unpinned npx skills invocation, exposing it to the same conditional package-execution supply-chain risk as the project-update variant. Updating globally can also affect skills used across projects, but the supplied file only documents this command and does not demonstrate automatic execution.

The workflow uploads user photos to an external service without a privacy warning.

Medium

• Category: Output Handling
• Confidence: 92% confidence

Finding

The workflow instructs the agent to upload the supplied photos through an upload grant and HTTP PUT, but does not warn the user that their image contents will leave the local system for external processing. Approval is requested later for billable animation, after the upload has already occurred.

Requests music, speech, and voice-management authorization for a silent photo-clip skill.

Medium

• Category: Excessive Agency
• Confidence: 99% confidence

Finding

The authorization scope includes music generation, speech generation, and voice reading and writing, although the skill promises silent photo clips. These unnecessary permissions increase the capabilities available to a compromised skill or stolen credential, potentially enabling unauthorized voice-management operations and unrelated resource consumption. User approval and private credential storage do not eliminate this least-privilege violation.

MCP server referenced without pinned version: 'npx skills'.

Medium

• Category: MCP Rug Pull

Finding

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.
