Gemini Skill Tutorial: Build Reusable AI Skills for Branded Posters and Video Workflows
When you use AI every day, one frustration keeps coming back: it loses track of instructions as a conversation grows or moves between tasks. Starting a new chat does not solve everything, either. Repeatedly pasting a long prompt with the same formatting rules and brand requirements takes time. Gemini Skills offer a reusable way to package those instructions.
Define a workflow once, then let Gemini recognize when it is relevant. You can also combine related skills in the same conversation. The first part of this Gemini Skill tutorial explains creation, activation and four ways to refine your instructions. The second part takes the workflow into AI9app: export a skill, save its instructions and use AI Media Agent to plan image and video prompts for branded posters and AI short dramas. Media production then depends on the generation tools and settings available in the platform.
1. Why Learn Gemini Skills? Three Changes from Gems
Many users are familiar with Gemini's custom assistants, known as Gems. Google has announced a transition from Gems to Skills. Availability and migration timing vary by account type, region and rollout stage, so check your account and the latest official announcements. Think of a skill as a reusable standard operating procedure that the AI can consult before it starts work.
How Gems and Skills differ:
Activation: With Gems, users typically open a particular assistant to begin a conversation. A skill can be recognized from the task context or explicitly selected through the options available in the interface.
Combining workflows: Gems center on individual assistant configurations. Skills can bring several related processes into one conversation, such as meeting summaries, data cleanup and presentation planning.
Portability: Skills can use the SKILL.md instruction format. After downloading or importing one, check the destination platform's support for tools, attachments, archives and instructions. A portable format does not guarantee identical functionality everywhere.
A useful rule for a company knowledge library is to give each skill one focused job. For example, a pre-event press release, a post-event announcement and an executive speech are three different tasks and can be maintained as three separate skills.
Over time, a collection of focused skills becomes a reusable library of your company's working procedures.
2. Gemini Skill Setup: From Creation to Activation
Step 1: Open the Skills Manager
Open Gemini in your web browser. Go to Settings and look for Skills. The exact location and surrounding options can change as the interface evolves.
Choose Create to start a new skill. If you already have a skill from another compatible platform, use the upload or import option shown in your account and check its supported file formats.
Step 2: Build a Skill with Gemini Using Three Core Elements
Choose the option to create a skill with Gemini, where available, and start with a request such as "Create a skill." You can specify your preferred language. Define these three elements clearly:
Core function: Explain the result the skill should produce. For example, turn a long article into separate Facebook, Threads and Instagram posts, with an accompanying image prompt.
Trigger condition: Describe when the skill applies. For example, use it when a user provides an article, blog URL or newsletter and asks for social-media adaptations. A specific trigger helps distinguish the skill from unrelated tasks.
Format and rules: Specify length, tone and layout requirements for each output. Do not put account passwords, credentials or sensitive personal information into reusable skill instructions.
Once the definition is ready, use the interface's save or submit control to store the skill.
Step 3: Test Activation in a New Conversation
Open a new chat, provide an article and state the task. If the skill does not activate, explicitly request it and review its name and description. Check any activation indicator in the interface, then compare the result against your acceptance criteria. Indicator wording can differ between versions.
3. Four Ways to Refine Your Gemini Skills
For dependable results, treat the first version as a starting point. These four techniques help you improve the instructions through actual use.
Calibrate the Skill with an Approved Example
When a result is not quite right, you do not have to rewrite everything from scratch. Return to the skill's menu and look for the editing or calibration options available in your version. The menu may also include actions such as use now, download, replace or disable.
Provide the version you revised and approved, or an example accepted by your manager. Ask Gemini to compare it with the original output, identify the differences and update the instructions accordingly. This refines the saved workflow; it is not a guarantee of perfect future results.
Match Your Writing Style Using Relevant References
Use an available writing-style skill or supply approved writing samples so Gemini can identify your tone and structure. If the workflow refers to Google Drive, Gmail or other connected sources, the relevant connections and permissions are still required. Creating a skill does not automatically give it access to all your files and messages.
Use Reverse Prompting When You Do Not Know Where to Start
Instead of trying to write every rule yourself, ask the AI to interview you. Try this request:
"I want to create a skill for [task]. Ask me a few questions about my objective and boundaries first. Then use my answers to create a skill that fits my workflow."
Break Complex Work into Reviewable Stages
For a task such as YouTube performance analysis and script improvement, divide the workflow into stages. First, clarify the objective and review the conversion funnel and packaging, then discuss the findings with the user before proceeding.
Next, compare video timelines, examine audience drop-off during the opening 30 seconds and standardize the available data. Finally, produce an optimization report and a revised script.
4. Export Gemini Skills to AI9app and Use AI Media Agent
After building and refining a skill, use the download or export option available in its menu. You can then bring compatible instructions into AI9app for your image and video workflow.
How Gemini Skills and AI9app Work Together
AI9app provides image and video generation tools, AI Media Agent and skill-storage features. Keep one principle in mind: a visual-production skill should focus on teaching the agent how to plan and write a useful image prompt or video prompt.
Build the prompt-writing skill in Gemini: create a focused workflow for branded advertising-poster prompts or short-drama camera and scene prompts, then download it.
Save the skill in AI9app: use the supported skill import or storage workflow. Check compatibility before assuming that attachments or tool instructions will transfer unchanged.
Plan with AI Media Agent: ask the agent to follow the skill's instructions when developing your visual concept and image or video prompts. Then review the available model, generation settings and cost before producing the final customized poster or video.
5. Two Practical Skill Templates for AI9app
The following templates focus on visual planning and prompt generation for AI Media Agent. Paste the relevant instructions into Gemini's skill-creation conversation, refine them for your business, and export them for use in a compatible AI9app skill workflow.
Template 1: Branded Advertising Poster Prompt Skill
Copy this request into Gemini:
"Create a skill named Brand-Poster-Prompt-Skill. I intend to download it and save its instructions in AI9app. Its purpose is to help AI Media Agent plan advertising posters and write image prompts that follow my company's visual identity."
Rules:
1. Core task and trigger: Use this skill when the user provides a product name or promotional theme and requests a branded poster. Your task is visual planning and the creation of an image prompt for AI9app.
2. Brand style, to be replaced with the company's actual guidelines: Use a modern, minimal commercial-photography aesthetic. The example palette is deep blue and champagne gold, with cinematic rim lighting and detailed product textures. Keep 30% of the composition as clean negative space for a headline and logo added later. Descriptive terms such as "8K detail" express a visual goal, not a guaranteed export resolution.
3. Follow a two-stage workflow:
Step 1, confirm the visual concept: Suggest two poster concepts and appropriate aspect ratios, such as 9:16 or 4:5. Ask the user which direction they prefer.
Step 2, output the image prompt: Once the user confirms a direction, provide a structured prompt in Chinese and English.
Image Prompt: [Product subject and material details] + [Company palette and background setting] + [Commercial lighting and camera direction] + [Composition reserving 30% clean negative space].
Negative Prompt: Exclude unwanted lettering, distorted objects, poor image quality and visual elements that undermine the intended premium look. Use a dedicated negative-prompt field only if the selected model supports it.
Template 2: AI Short-Drama Storyboard and Video Prompt Skill
Copy this request into Gemini:
"Create a skill named AI-Drama-Prompt-Skill. I intend to download it and save its instructions in AI9app. Its purpose is to help AI Media Agent plan short-drama storyboards and write character-consistent image prompts and motion-focused video prompts."
Rules:
1. Core task and trigger: Use this skill when the user provides a story idea or requests an AI short drama. Plan the storyboard and produce image prompts for the opening frames and video prompts for the moving shots.
2. Follow a three-stage workflow, advancing after the user confirms each stage:
Step 1, establish the story and character appearance: Plan a 60-second short drama with a twist, paying particular attention to a visual hook in the opening three seconds. Write a character anchor that specifies facial features, hairstyle and clothing materials. Reuse it to reduce appearance drift, while also using character reference images and checking every shot. Text descriptions alone cannot guarantee an unchanged face.
Step 2, break the story into shots: Create six to eight shots. For each, provide the shot number, framing, on-screen action and dialogue.
Step 3, output image and video prompts: Provide both prompt types for each shot so the media can be generated in AI9app.
Image Prompt, for the opening frame: [Fixed character anchor from Step 1] + [The shot's opening pose and micro-expression] + [Scene setting and cinematic lighting].
Video Prompt, for movement: [Camera direction, such as slow push-in, pan right or handheld shake] + [The progression of body movement and facial expression] + [Environmental motion, such as flickering light or hair moving in the wind].
6. Build Your Own Library of AI Production Skills
This Gemini Skill tutorial gives you a practical starting point: use reverse prompting and staged reviews to turn recurring requirements into reusable instructions. Then export the workflows that specialize in visual and filmmaking prompts and save compatible instructions in AI9app.
When you work with AI Media Agent, use the skill to plan branded posters and short-drama prompts. Review the generation settings and cost, produce the media, and improve the instructions based on the results. A maintained skill library makes your creative workflow more repeatable without removing the need for human review.
Before You Start: Availability, Costs and Tool Links
This article is free to read. A skill stores instructions and workflows; it does not grant extra image-generation, video-generation or cloud-data access rights. Support for SKILL.md, attachments and archives differs between platforms. If direct import is unavailable, paste the core instructions into the platform's custom-skill fields. Available models, usage allowances and media-generation fees are determined by the tool page.
Staged delivery means having the user review work step by step. Technical progressive disclosure means loading detailed instructions and reference files only when needed. They can work together, but they are not the same concept.
