Google has introduced two significant innovations in Gemini: Gemini for Argon and Gemini Skills. Gemini for Argon is a model that ranked first in the real-world professional work opinion index. Gemini Skills allows you to train Gemini to perform a task once and guarantee its consistent execution in the future.

Gemini for Argon Key Metrics

For general users, the following three metrics are important:

1. Massive Multitask Language Understanding (MMLU) Index: Gemini for Argon ranks first among 41 models in tests conducted in the fields of finance, law, text processing, and programming.
2. Hallucination Test: Gemini for Argon makes errors (fabricates information) in only 15% of cases, while GPT-6 Astra does so in 51%.
3. Token Processing: The model can process up to 1 million tokens at once, which is equivalent to several books or an entire project folder.

Gemini Availability for Argon and Skills

Gemini Skills is available for free on the free plan. Gemini for Argon requires a Pro subscription. The anti-gravity coding agent, designed to work with Gemini for Argon, is only available on the Ultra plan.

How Gemini Argon and Skills Work

Skills can be thought of as a job description, and Argon as an employee who strictly follows those instructions. Google claims that Argon follows style instructions better than previous Gemini versions and is capable of creating actual products, not just drafts. A toggle has appeared in the chat interface, switching from "Chat" mode to "Task" mode, allowing Gemini to work with your Google applications in the background.

A Skill is a small Markdown file containing a description (how Gemini decides when to use it) and instructions. Reference files, such as PDFs or spreadsheets, can optionally be included.

There are three main ways to create Skills, which will be demonstrated. All Skills used in this review are available in a free guide that includes 35 ready-to-use Skills, including 5 specifically designed for Argon.

Task #1: Inbox Triage

The first method of creating a Skill is through chat. The user is prompted to create a Skill called "Inbox Triage." Upon receiving a set of emails, Gemini should sort them into four categories: "Reply Today," "Reply This Week," "Delegate," and "Archive."

After the request is fulfilled, the "Inbox Triage" Skill is saved and activated in Gemini. To use it in chat, simply type "@inbox triage" and provide a set of emails. Gemini, with access to Gmail, analyzes the emails and provides the results according to the specified categories. If necessary, Gemini also offers to draft replies to specific emails. This method significantly saves time compared to manually writing detailed prompts.

Task #2: Creating a Proposal for a Client

The second method for creating a Skill involves uploading a ready-made skill.md file. This file contains the name, description, proposal, scope of work, rules, and links.

For this task, the "Scope of Work" Skill was created. After uploading the ZIP archive containing skill.md and a CSV file with rates, the Skill becomes available. When using "@scope of work" and providing notes from an introductory call, Gemini generates an 8-page proposal presentation for the client. The result looks professional and can be edited or exported in various formats (slides, PDF, PPT). Using reference files with rates ensures that Gemini does not invent prices.

Task #3: Optimizing Content for YouTube

For this task, three separate Skills were created: "Thumbnail Title," "Hook Writer," and "YouTube Description."

By combining these three Skills in one chat and providing the video script, Gemini generates:

• 10 hook variations with analysis of the top 3.
• 5 thumbnail title variations and "title-thumbnail" pairs.
• A YouTube description with tags and chapters.

This approach significantly speeds up the YouTube content creation process, reducing the time from 30-45 minutes to 1 minute.

Task #4: Analysis of Data from Spreadsheets (Data Snapshot)

A "Data Snapshot" Skill has been created to work with spreadsheets. When a spreadsheet is uploaded or pasted into the chat, Gemini should identify the three most significant changes compared to the previous period, indicating exact figures and percentage ratios.

This Skill is particularly useful for analyzing channel data over the last 90 days to determine content creation strategies for increasing views and subscribers, as well as for analyzing audience requests. After creating the "Data Snapshot" Skill and uploading a CSV file with channel data, Gemini can convert this data into an interactive dashboard that can be printed, downloaded as a PDF, or copied for sharing.

Task #5: Weekly Report and Errors in Skill Creation

A "Weekly Status" Skill was used to create a weekly report. After its activation, Gemini generated a report divided into the sections "Shipped," "In Progress," and "Next Week."

Next, the process of editing the Skill was demonstrated: a "Blocked" section was added between "In Progress" and "Next Week." Gemini successfully updated the Skill and provided the result with the new section.

Five Common Errors When Creating Skills:

1. Unclear Rules: Instead of general phrases ("be professional"), specific instructions should be used (e.g., "three bullet points under 120 words").
2. Weak Description: The description is the trigger for Gemini. It should be as precise and informative as possible.
3. Lack of Reference Files: This leads to the model having to fill in the gaps itself, which can reduce accuracy.
4. No Synchronization with Google Workspace: Skills created in the Gemini app do not synchronize with Google Workspace. They must be created separately for each application.
5. Editing the Output Instead of the Skill: If the result is 80% aligned with expectations, the Skill itself should be corrected, rather than attempting to edit each output.

Replacing Gems with Skills

Starting November 17th, Gems will be moved to the settings panel. For personal Google accounts, Gems will begin to be removed in November. For Workspace accounts, this will not happen before March 1, 2027, and for educational accounts, it will be June 1st. Google will automatically transfer remaining Gems to Skills drafts, but Gems created in Google Labs will not be migrated. It is recommended to convert existing Gems to Skills, which will take approximately two minutes per item.

Versatility of Skills

Skills are ordinary files that can be downloaded from Claude, ChatGPT, or Gemini and used in any preferred tool.

Verdict

For those involved in writing plans or reports, Argon combined with Skills is the closest thing to an "AI employee" solution. For short and repetitive tasks, using the free Skills is sufficient and will save hours of work. In any case, the priority is to create a library of Skills, as the model itself can be replaced, but the library remains a valuable asset.
