Fintech domain constraints and design patterns for building precise, auditable financial systems in Rust.
Automate repetitive workflows and reduce manual effort
Example: Generate reports, summarize documents, draft communications
Save 3-5 hours per week on routine tasks
Learn new skills, understand complex topics, get expert guidance
Example: Explain concepts, provide examples, suggest learning resources
Accelerate learning and skill development by 2x
Enhance output quality through reviews, suggestions, and refinements
Example: Review drafts, suggest improvements, catch errors
Improve work quality by 30-40% with less effort
Time estimate: 15-45 minutes depending on use case complexity

Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versiondomain-fintechExecute the skills CLI command in your project's root directory to begin installation:
epx add zhanghandong/rust-skills --skill domain-fintechFetches domain-fintech from zhanghandong/rust-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
.cursor/skills/domain-fintech
Restart Cursor to activate domain-fintech. Access via /domain-fintechin your agent's command palette.
