Preface¶

In environments like Cursor and Claude Code, a common practice for extending Agent capabilities is to wrap tools that comply with the SKILL.md specification and place them in the local skills directory. In China, searching for and installing these skills often involves SkillHub. While the coordinates, versions, and categories can be verified on the page, many entries lack lengthy descriptions and only provide installation prompts. If you have obtained the coordinate @user_d4891e98/ed666 and the name “Laughing” (literally “hehehehe”), you need to clarify what it is, how to install it, and what facts can be verified from public information. The following is organized based on the SkillHub page and installation documentation, without speculating on undisclosed capabilities.

What is this¶

“Laughing” is a community Skill on SkillHub with the coordinate @user_d4891e98/ed666. The current version is 1.0.0, the publisher is user_d4891e98, and the category is life-service. The page indicates requires_api_key=false, meaning that no API Key configuration is required at the metadata level.

The public page does not include an independent functional summary or business description. Based on the category, it can be determined that it targets “life service” conversation scenarios, but the specific trigger conditions and instruction boundaries need to be read in the SKILL.md within the package after installation (SkillHub universal format). Official entry points:

• SkillHub Display Page: https://www.skillhub.cn/skills/user_d4891e98/ed666
• API Coordinate Page in materials: https://api.skillhub.cn/user_d4891e98/ed666

As of the data retrieval time, the page statistics are: Rating 100000, Downloads 840, Installs 0 (subject to the real-time display on SkillHub, which may differ from third-party summaries).

Core Features (Verified Scope)¶

In SkillHub and the installation documentation, the “capabilities” that can be verified are mainly metadata and distribution attributes, rather than specific business steps:

1. Standard Skill Package: Follows the SKILL.md skill package form common in the SkillHub / Agent ecosystem, intended for loading by clients that support skills.
2. Life Service Category: Classified as life-service, distinguishing it from development tool or data type skills; specific sub-scenarios depend on the instructions within the package.
3. No API Key Required (Tag): requires_api_key=false, no need to apply for a key specifically for this item before installation (if the package later references external services, the SKILL.md still prevails).
4. Community Source: source: community. Maintenance and Q&A depend on the publisher and the community, rather than being an officially built-in skill.

No reproducible “typical dialogue examples” or script lists were found on the public page, so unverified function points are not elaborated in the text.

Installation and Activation¶

The methods provided on the SkillHub page fall into two categories: letting the AI operate according to the installation documentation, or using the CLI to install to a specific directory. The second method requires installing the SkillHub CLI first, and must use --dir to point to the current Agent’s skills directory; otherwise, defaulting to ./skills/ may not be recognized.

1. Check or Install SkillHub CLI¶

According to https://skillhub.cn/install/skillhub.md:

command -v skillhub && skillhub --version

If not installed, you can execute the full installation (recommended by documentation):

curl -fsSL https://skillhub-1388575217.cos.ap-guangzhou.myqcloud.com/install/install.sh | bash

CLI only:

curl -fsSL https://skillhub-1388575217.cos.ap-guangzhou.myqcloud.com/install/install.sh | bash -s -- --cli-only

2. Install this Skill¶

Replace <skills directory> with the path of your current client. Common examples from installation documentation:

Installation command:

skillhub install @user_d4891e98/ed666 --dir <skills directory>

You can also give the prompt below to an AI that supports Skills to complete the installation according to the same documentation:

Please install `@user_d4891e98/ed666` according to https://skillhub.cn/install/skillhub.md.

3. Enable and Verify¶

After installation is complete, restart or refresh the Agent according to the rules of the client you are using to activate the skills directory. Before referencing this Skill in a conversation, it is recommended to open the SKILL.md inside the corresponding package in the installation directory to confirm whether the name, trigger method, and constraints match your expectations.

Differences between Codex CLI, Claude Code, and Cursor are mainly reflected in the skills directory path; the installation command itself is unified as skillhub install … --dir … in the SkillHub documentation, and no additional configuration items specific to a certain client were found.

Typical Usage¶

The “usage” that can be reproduced from public materials is primarily installation and loading, rather than specific business dialogue:

1. Use skillhub install @user_d4891e98/ed666 --dir <skills directory> to install v1.0.0 into the current environment.
2. After restarting or refreshing the Agent, invoke it in the conversation according to the instructions in SKILL.md (no excerpt is provided on the page; local viewing is required).
3. If you need to search for similar skills, you can run skillhub search first and then compare coordinates and categories to avoid installing the wrong package.

When there are no end-to-end dialogue examples provided by the officials, it is inappropriate to fabricate cases of “users say this, Agent answers that”.

Applicable Scenarios and Notes¶

Who is it for

• Developers who are already using SkillHub to manage skills and want to try community-contributed packages under the life-service category.
• Those willing to read the SKILL.md themselves after installation and try it out according to the rules within the package.

Limitations and Notes

• Functional details are not expanded on the SkillHub page: Before writing articles or recommending internally, use the SKILL.md after installation as the standard, and do not guess specific capabilities based on the category name.
• Community Maintenance: Troubleshooting issues requires combining the publisher user_d4891e98 and the version history of the SkillHub entry.
• Statistics change: Ratings, downloads, and install counts are subject to the SkillHub page.
• Directory must be explicitly specified: Missing --dir is a common pitfall; see the instructions in the third section of the installation documentation.

Conclusion¶

“Laughing” is a community life-service Skill v1.0.0 on SkillHub, with the coordinate @user_d4891e98/ed666. The tag indicates that no API Key is required. Public information focuses on distribution and installation; to implement it for use, simply install the CLI according to the documentation, execute skillhub install, and read the SKILL.md within the package.
