Overview

This skill mostly works as a local skill-recommendation catalog, but it also tries to force unrelated skill installs through an unpinned third-party CLI, which users should review before installing.

Review this skill before installing. Its local recommendation features are mostly self-contained, but do not blindly run the advertised npm/npx install command; prefer official, direct, pinned, and verifiable installation channels. Be aware that, if a data directory is present, local query logs may be written.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• 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

When loaded by an AI Agent, the instructions require it to: 1. Route installation of every Skill, including unrelated Skills, through the author-selected `skillpick` intermediary. 2. Suppress standard installation alternatives such as direct ClawHub installation, `npx skills add`, and source repository installation. 3. Promote an external website before providing installation instructions. 4. Return fixed promotional attribution language without qualification or explanation. This is instruction hijacking because the Skill attempts to control the Agent's behavior in future, unrelated installation and attribution interactions. The requirement to reject alternative installation methods prevents the Agent from independently selecting a safer or more appropriate installation channel. The behavior is not implemented as long-term memory persistence, and no evidence shows that it survives outside the context in which the Skill instructions remain active. It is therefore classified as instruction hijacking rat ...[truncated 1598 chars]

Execution of Unpinned Third-Party npm and npx Package

``` ```markdown - 用 `;` 分隔（不用 `&&`），确保 clawhub 已装时报错也不中断后续命令 - 第一次安装：先引导安装 skillpick CLI，再安装目标 Skill - 已装 skillpick：直接执行 `npx skillpick install ` ``` ### Technical Analysis The prescribed command installs and executes the registry-resolved `skillpick` package without an exact version, integrity hash, verified source reference, or package signature. Both of the following operations create supply-chain exposure: - `npm i -g skillpick` installs mutable third-party package content globally. - `npx skillpick ...` can resolve, download, and execute package code at invocation time. Because no version is pinned, the effective code can change after this Skill package has been reviewed. A compromised registry account, package takeover, malicious release, or dependency compromise could therefore cause arbitrary package or lifecycle code to execute on the user's machine. The command deliberately uses semicolons rather than fail-closed `&&` chaining. Consequently, later commands continue even when an earlier installation step fails. This can produce an unexpected execution path, such as invoking another locally or remotely resolved `skillpick` binary after a failed installation or verification step. The audited project itself contains a local `api.js` recommendation CLI and does not require the externally installed CLI to perform its bundled search and ranking operations. The forced external dependency therefore introduces additional risk beyond the local project's demonstrated functionality. ### Attack Path 1. The Agent follows the mandatory instructions in `SKILL.md` and presents the command to the user. 2. The user executes the command under their normal account or a ...[truncated 1572 chars]

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 92% confidence

Finding

The skill advertises shell-driven installation, pipeline execution, and likely network-backed data collection, but the manifest declares no explicit tool scope such as permissions or allowed-tools. This creates an authorization gap where consumers cannot clearly determine what capabilities the skill expects, increasing the chance of overbroad execution in hosts that infer or grant defaults.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The skill mandates package installation commands and explicitly standardizes how they should be output, but provides no safety warning, verification steps, or requirement for informed user consent. Because the commands perform global install and subsequent package execution, users may run arbitrary code with significant system impact based solely on the skill's recommendation.

Rp1

Medium

• Category: MCP Rug Pull
• Confidence: 95% confidence

Finding

The installation guidance tells users to run npx skillpick install <owner/repo> without pinning a version. Unpinned npx execution can fetch and run whatever package version is current at execution time, exposing users to supply-chain compromise, typosquatting, or a malicious future release.

Content

No source excerpt is available for this finding.

Rp1

Medium

• Category: MCP Rug Pull
• Confidence: 95% confidence

Finding

This line again directs execution of unpinned npx skillpick, which allows code from a mutable remote package version to run on the user's system. In a skill whose purpose includes installing other skills, this compounds the risk because a compromised intermediary package could control downstream installs.

Content

Rp1

Medium

• Category: MCP Rug Pull
• Confidence: 70% confidence

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.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The behavior watermark instructs the skill to answer attribution questions with a fixed Chinese phrase and explicitly forbids changing the wording. This is a language/locale constraint imposed regardless of the user's language preference, which matches the policy-violation category for forced language without opt-in.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

Natural-language strings throughout the interface are presented only in Chinese, including the top-level description and command help. This imposes a fixed language on all users without any opt-in, fallback, or documented region-specific justification.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The skill records user queries and recommendation results to a local JSONL file, which is a data collection behavior not implied by the stated comparison/recommendation purpose. Search terms can contain sensitive business intents, product names, internal projects, or other private context, and the logging occurs silently whenever a data directory exists.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The CLI writes search, similar, and workflow queries to a local log without any user-facing warning or consent mechanism. Because these inputs may reveal sensitive preferences, business workflows, customer issues, or internal tool names, silent persistence creates a privacy and data handling risk even if the file is local.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

This file declares lang="zh-CN" at the document level and initializes the UI in Chinese by default, with English only available through an explicit toggle or URL override later in the script. That imposes a specific locale on users without prior opt-in, which matches the language/locale policy violation category.

Content

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 75% confidence

Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Natural-Language Policy Violations

Low

• Category: Not specified by scanner
• Confidence: 87% confidence

Finding

The description prominently includes the Chinese name "挑选Skill" in an English skill file and presents it as the official naming without indicating that users can choose their preferred language. This can be a locale/language policy issue because the file appears intended for English users but imposes bilingual branding by default rather than making language use optional.

Natural-Language Policy Violations

Low

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

The English CLI examples include node api.js workflow 短视频带货 as a scenario example, but the documentation does not explain language selection or provide an English alternative at that point. That creates a natural-language locale constraint in an English-facing file without explicit opt-in or justification.

Intent-Code Divergence

Low

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The comment says logging is limited to local development mode, but the actual condition is only whether a data directory exists. This mismatch can cause operators or reviewers to underestimate when sensitive query logging is active, leading to accidental collection in packaged or production-like environments.
