> Ready-made viaNexus vAST playbooks for AI agents: audit viaNexus vAST dataset permissions, look up financial data with viaNexus vAST. Free SKILL.md files for Claude Code, Cursor and Codex, or one click in RevampKey.

## Skills

- [Use viaNexus vAST safely with AI agents](https://revampkey.com/marketplace/vianexus-vast/skills/essentials.md): Guidance for connecting the viaNexus vAST financial data connector: confirm the account and dataset scope, pick the right tool, and handle entitlement blocks. The agent asks before changing any access rule.
- [Audit viaNexus vAST dataset permissions](https://revampkey.com/marketplace/vianexus-vast/skills/dataset-permission-rules-audit.md): Reviews the dataset access rules on a viaNexus vAST account against the access you intend, flags rules that are too broad, too narrow or missing, and proposes changes. It asks before creating or deleting any rule.
- [Look up financial data with viaNexus vAST](https://revampkey.com/marketplace/vianexus-vast/skills/financial-data-lookup.md): Answers a financial data question by searching the viaNexus catalog, fetching only the rows you are entitled to, and reporting the source, as-of date and coverage gaps. It asks before changing any account permissions.

### What is a viaNexus vAST agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each viaNexus vAST skill describes one job, which viaNexus vAST tools to use in which order, what to check first and when to stop and ask you.

### Do the viaNexus vAST skills change anything on their own?

The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in viaNexus vAST.

### Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect viaNexus vAST; elsewhere you copy the folders into your project or skills directory.

### Do I need the viaNexus vAST MCP server too?

Yes. The skills tell the agent how to do the work; the viaNexus vAST MCP server gives it the tools to do it. The viaNexus vAST MCP setup guide covers every client.
