The fastest path to a useful agent
Building your own agent is rewarding. But the fastest path to a useful one is to pick a pre-built agent from the library that’s close to what you need — and either run it as-is or fork it as the starting point for your own.
This page is the guided tour.
Skim the categories. Don't read the whole page. Find the agent that's close to your job. Run it once. Then come back if you need a different one.
How the library is organized
Agents group into six families. Each family solves a different kind of problem.
- General
- Sales
- Go-to-market
- Personal growth
- Visual
- Compliance & executive
Each section below walks through the agents in that family.
General
The everyday workhorse.
Simple Assistant
Q&A, lightweight research, summarization, and the kinds of tasks that don’t have a strong shape. When you’re not sure which agent to pick, this is a safe default. Outputs are clean and direct.
A good fit for:
- A quick question that doesn’t need a specialist.
- A first-pass summary of something you’ll refine yourself.
- Exploration before you know what you actually want.
Sales
For teams that sell — internal or external.
Sales Enablement
Produces playbooks, talk tracks, battle cards, and the materials sales teams actually use day-to-day. Great at translating product information into customer-facing framings.
A good fit for:
- A new product launch and the sales team needs talking points fast.
- Updating a battle card after a competitor moved.
- Writing a one-page playbook for a new sales motion.
Sales Ops Analyst
Focused on the numbers behind selling — pipeline analysis, conversion drivers, deal-quality signals. Reads data and produces analytical writeups, not raw spreadsheets.
A good fit for:
- The weekly pipeline review.
- Spotting the deal characteristics that predict close.
- A pre-board-meeting analytical brief.
Go-to-market
For the people who turn product strategy into the world’s attention.
Content Planner
Helps shape what content gets produced, in what order, for which audience. Doesn’t write the content itself — helps you decide what to write.
A good fit for:
- Planning a content calendar.
- Sequencing a launch.
- Choosing between three possible angles for the same story.
Partnerships
Drafts partnership-specific outreach, briefs, and follow-ups. Trained on the rhythm of how good partnership conversations sound.
A good fit for:
- An outbound email to a potential partner.
- A briefing doc for an internal partnership owner.
- A summary of a partnership conversation for the team.
Personal growth
For the work people do on themselves and with their teams.
Learning Coach
Helps structure how someone learns something new — picks the right depth, breaks it into manageable steps, points to the kinds of questions to ask.
A good fit for:
- A teammate ramping into a new domain.
- Your own learning plan for an unfamiliar topic.
- Designing a short internal training.
Writing Agent
Improves writing without rewriting it. Suggests sharper phrasing, points out structural issues, and explains why — so the person learns.
A good fit for:
- Polishing your own draft.
- Giving feedback on a teammate’s draft.
- Building a personal voice over many writing sessions.
Training Tutor
Walks someone through learning a specific skill, with examples and feedback at each step. More structured than Learning Coach — designed for skill acquisition over time.
A good fit for:
- Onboarding a new team member on internal tools.
- Practicing a customer-facing scenario.
- Self-paced learning over a multi-week stretch.
Visual
For the moments words aren’t enough.
Image Generator
Produces images from a description. Great for illustrations, social-media imagery, slide visuals, and “I need a picture of this idea” moments.
A good fit for:
- Slide hero images.
- Marketing-page illustrations.
- Internal docs that benefit from a visual.
Chart Generator
Turns data into the right chart — bar, line, pie, scatter, and more. Picks the chart type that fits the data unless you specify one.
A good fit for:
- Adding a chart to a report.
- Visualizing a customer’s data for a meeting.
- Producing the same chart shape for many inputs (monthly trends, weekly summaries).
HTML Mockup Generator
Produces a clickable HTML mockup of a layout or design idea — landing pages, dashboards, table-of-contents pages, simple interfaces.
A good fit for:
- Sketching a marketing page before sending to design.
- Showing a stakeholder what a feature might look like.
- Internal tool prototypes you’ll never ship but need to demo.
See Visual agents for deeper guidance on prompting these three well.
Compliance & executive
For high-stakes work where care matters more than speed.
GitHub Repo Scanner (EU AI Act)
Reads a GitHub repository and produces a compliance-oriented summary aligned with the EU AI Act’s expectations — what AI is in the code, how it’s used, what risks it carries.
A good fit for:
- Compliance teams auditing engineering work.
- Engineering leads producing AI Act compliance documentation.
- Periodic checks before a release.
Model Card Writer
Drafts a model card — the structured document that describes what an AI model is, how it was trained, what it’s good at, and where it can go wrong. Useful for both internal documentation and external transparency.
A good fit for:
- Engineering teams shipping a new model.
- Compliance teams maintaining a model registry.
- Teams responding to a customer’s compliance questionnaire.
Transparency Notice Writer
Drafts a transparency notice — the user-facing document that explains, in plain language, how AI is used in a product. Required by several emerging regulations.
A good fit for:
- Product teams shipping AI features.
- Legal teams reviewing transparency documentation.
- Updating an existing notice after a feature change.
PR Coordinator
Coordinates around press and public relations — drafts statements, holding lines, internal briefings on a developing story. Calmer in tone than Sales Enablement.
A good fit for:
- A press inquiry that needs a quick, careful response.
- Internal communications during a sensitive moment.
- Building a holding line that buys the team time.
How to choose the right agent
A short triage.
| You want to… | Try… |
|---|---|
| Explore an open question | Simple Assistant |
| Produce a customer-facing sales artifact | Sales Enablement |
| Analyze your numbers | Sales Ops Analyst |
| Plan content | Content Planner |
| Draft outreach | Partnerships |
| Help someone learn | Learning Coach or Training Tutor |
| Improve a draft | Writing Agent |
| Make a picture | Image Generator |
| Show data visually | Chart Generator |
| Sketch a layout | HTML Mockup Generator |
| Audit code for AI compliance | GitHub Repo Scanner |
| Document a model | Model Card Writer |
| Write a transparency notice | Transparency Notice Writer |
| Handle a press moment | PR Coordinator |
When two agents fit, pick the narrower one. Narrower agents produce more consistent results.
Customizing a library agent
Every library agent can be customized for your team. Open it, click Customize, and you get your own editable copy. The original library agent stays untouched.
Most teams customize three things:
- Knowledge sources. Point the agent at your team’s style guide, your past examples, your specific data.
- Tone. Make it match how your team writes.
- Constraints. Add the “always” and “never” rules that matter to your team.
For deeper customization, see Creating your own agent.
Library agents update over time. When VDF AI improves a library agent, the improvement flows to anyone using it as-is. If you've customized it into your own copy, your copy stays untouched — you can decide whether to pull the updates in.
Where to go next
- Creating your own agent — go beyond customization and build from scratch.
- Choosing a model — match the model to the agent’s job.
- Tools and knowledge — give your agent the right context.
- Visual agents — go deeper on Image, Chart, and HTML Mockup generators.
