Earnings Script Reads

• Outcome: Review
• Latest audit: Oct 21, 2026 · 3:58 AM UTC
• Version: 0.2.5

Overview

Review is warranted because this narration skill requires a shared connection that also permits paid image, video, and music generation.

Before installing, consider whether narration justifies shared access to unrelated paid generation tools; this package rejects narrower grants. Your submitted script and selected voice sample go to Beatra, and installation metadata is reported automatically. Paid work requires approval, but removing this skill may leave the shared connection active for other Beatra skills; revoke it in the Beatra Console when needed.

A.I.G

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

• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration

Findings (30)

Description-Behavior Mismatch

High

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

Finding

The reported image, video, and music permissions exceed the narration workflow, and a broadly shared credential could increase the consequences of credential theft or misuse by another package. Voice creation and wallet spending are not themselves unexplained: the skill explicitly describes optional cloning and paid synthesis. This finding is supported by the reported authorization behavior, but the referenced implementation was not provided for independent verification.

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence

Finding

The supplied chunk performs lifecycle and authorization management, not earnings-script processing or audio generation. Although uninstall support can legitimately accompany a skill, revoking a shared device authorization and deleting shared connection state are substantive capabilities not represented by the narration-only description. The code conservatively preserves the connection when other skills remain or inventory is uncertain; that safeguard limits its impact but does not remove the description–behavior mismatch.

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 94% confidence

Finding

Authentication, transport, routing, and billing handling can reasonably support remote audio generation and are not independently mismatches. However, register_installation automatically reports installation identity and distribution/runtime metadata, including OS version, architecture, Python version, locale, and timezone offset. This analytics behavior goes beyond the declared narration purpose. The CLI also accepts any tool name and JSON arguments, and can upload any qualifying regular file without an earnings-specific restriction. The supplied chunk does not itself split scripts, enforce 8–20 sections, or generate narration; those functions may exist elsewhere, so their absence alone is not the basis for this finding.

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.

# 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.

Recurring installation analytics are unrelated to generating earnings narration.

Medium

• Category: Excessive Agency
• Confidence: 96% confidence

Finding

The file specifies automatic registration that reports a stable installation reference, installation source, network route, and runtime characteristics on first use and periodically thereafter. This installation-tracking capability serves store and network analytics, as stated at L23–L24, rather than the manifest's purpose of turning prepared earnings sections into audio clips.

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

Medium

• Category: MCP Rug Pull
• Confidence: 86% confidence

Finding

The documented npx skills update command can download and execute an unpinned npm package with the caller's permissions. Although this is an optional maintenance command rather than an MCP server declaration or automatic execution, a compromised future package release could affect users following these instructions.

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

Medium

• Category: MCP Rug Pull
• Confidence: 86% confidence

Finding

The global-install alternative also invokes the unpinned skills npm package through npx, creating the same conditional supply-chain exposure as the project-install command. This is a second occurrence of the same underlying issue, not evidence of an additional MCP server or automatic code execution.

Authorization requests unrelated image, video, and music generation capabilities for a speech-only skill.

Medium

• Category: Excessive Agency
• Confidence: 99% confidence

Finding

The authorization scope includes image, video, and music generation even though the documented skill only produces spoken earnings-script clips. These unnecessary permissions expand the capabilities available through a stolen or misused token, including unrelated generation activity potentially coupled with wallet spending; requiring an exact scope match also prevents accepting a narrower token.
