Select Cursor when prompted
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
◆ Which agents do you want to install to?

Verify installation
Confirm successful installation by checking the skill directory location:
.cursor/skills/zod-validation-utilities
Restart Cursor to activate zod-validation-utilities. Access via /zod-validation-utilities in your agent's command palette.

Security Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.
Production-ready Zod v4 patterns for reusable, type-safe validation with minimal boilerplate. Focuses on modern APIs, predictable error handling, and form integration.
When to Use
Defining request/response validation schemas in TypeScript services
Parsing untrusted input from APIs, forms, env vars, or external systems
Standardizing coercion, transforms, and cross-field validation
Building reusable schema utilities across teams
Integrating React Hook Form with Zod using zodResolver
Instructions
Start with strict object schemas and explicit field constraints
Prefer modern Zod v4 APIs and the error option for error messages
Use coercion at boundaries (z.coerce.*) when input types are uncertain
Keep business invariants in refine/superRefine close to schema definitions
Export both schema and inferred types (z.input/z.output) for consistency
Reuse utility schemas (email, id, dates, pagination) to reduce duplication
Validation Workflow
When integrating validation into an API handler or service:
Define the schema at the boundary (handler, queue, config loader)
Parse with safeParse to handle errors gracefully
Checkresult.success to branch on failure/success
Useresult.data with full type inference in success path
Return formatted errors or proceed with validated data
See example 7 (safeParse workflow) for the complete pattern.
import{ z }from"zod";exportconst PaginationQuerySchema = z.object({ page: z.coerce.number().int().min(1).default(1), pageSize: z.coerce.number().int().min(1).max(100).default(20), includeArchived: z.coerce.boolean().default(false),});exportconst DateFromUnknownSchema = z.preprocess((value)=>(typeof value ==="string"|| value instanceofDate? value :undefined), z.coerce.date({ error:"Invalid date"}));exportconst NormalizedEmailSchema = z
.string().trim().toLowerCase().email({ error:"Invalid email"}).transform((value)=> value as Lowercase<string>);
import{ z }from"zod";exportconst PasswordSchema = z
.string().min(12).refine((v)=>/[A-Z]/.test(v),{ error:"Must include an uppercase letter"}).refine((v)=>/

Make data-driven prioritization decisions faster
Stakeholder Communication
Draft PRDs, status updates, and stakeholder presentations
›Access to product documentation and roadmap tools (Jira, Notion, etc.)
›Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
›Stakeholder contact information and communication channels
Time Estimate
30-60 minutes to see productivity improvements
Steps
1Install product management skill
2Start with user story generation for known feature
3Progress to competitive analysis: research 2-3 competitors
4Use for roadmap prioritization: apply RICE/ICE scoring
5Draft stakeholder communications and refine based on feedback
6Build template library for recurring PM tasks
7Share effective prompts with product team
Common Pitfalls
⚠Not validating competitive research—verify facts before sharing
⚠Accepting user stories without involving engineering team
⚠Over-relying on frameworks without qualitative judgment
⚠Not customizing outputs to company culture and communication style
⚠Skipping stakeholder validation of generated requirements
Best Practices
✓ Do
+Validate research and competitive analysis with real data
+Collaborate with engineering when generating technical requirements
+Customize frameworks and templates to your company context
+Use skill for first drafts, refine with stakeholder input
+Document successful prompt patterns for PM tasks
+Combine AI efficiency with human judgment and intuition
✗ Don't
−Don't publish competitive analysis without fact-checking
−Don't finalize user stories without engineering review
−Don't make prioritization decisions solely on AI scoring
−Don't skip customer validation of generated requirements
−Don't ignore company-specific context and culture
💡 Pro Tips
★Provide context: company goals, constraints, customer feedback
★Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
★Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
★Use skill for 70% generation + 30% customization to company needs
When to Use This
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
