User Stories for AI Agents — Templates & Best Practices

AI agents consume requirements differently than humans. This guide teaches you how to write user stories optimized for AI-driven engineering workflows using ProdMoh + MCP.

Why User Stories Must Evolve for AI

Traditional user stories—“As a user, I want X so that Y”—were written for human developers who fill in the missing details based on context, prior knowledge, or engineering norms.

AI agents, however, cannot compensate for missing specificity. Without structure, constraints, examples, and predicates, an LLM:

Key Insight

AI agents require structured, machine-readable user stories that can be parsed into tests, mocks, flows, and implementation scaffolds.

What Is an AI-Ready User Story?

An AI-ready user story is a structured requirement designed for consumption by:

Unlike traditional stories, AI-ready stories contain:

  1. Intent: what changes for the user
  2. Acceptance Criteria (Predicates): machine-verifiable logic
  3. Examples: concrete inputs and outputs
  4. Constraints: technical rules the AI must follow
  5. NFRs: latency, security, performance
  6. Metadata: version, author, timestamps

The AI User Story Template (ProdMoh Standard)

Here is the canonical structure used by ProdMoh and compatible with MCP + agentic IDEs:

{
  "id": "",
  "title": "",
  "intent": "",
  "acceptance": [],
  "examples": [],
  "constraints": [],
  "nfr": [],
  "meta": { "version": "", "author": "" }
}

Let’s break down each component with examples, anti-patterns, and best practices.

1. Writing Intent: How to Express the User Goal Clearly

The intent section should describe the user-facing outcome with zero ambiguity.

Bad Example

“User should be able to save their profile easily.”

Why It Fails

Good Example

“User can update profile information including name, email, and avatar. Updates must validate email, enforce avatar size limits, and persist to the profile service.”

This gives the AI:

2. Acceptance Criteria for AI (Predicates, Not Prose)

Acceptance Criteria must be machine-readable predicates so that AI can directly:

Good Predicate Examples

{"type":"predicate","expr":"response.status == 200"}
{"type":"predicate","expr":"user.email matches /^[^@]+@[^@]+\\.[^@]+$/"}
{"type":"predicate","expr":"avatar.size_bytes <= 5242880"}

3. Examples: The Most Powerful Part of AI User Stories

Examples disambiguate everything. They give AI concrete grounding in domain logic.

Example for Profile Update Story

{
  "input": {
    "name": "Jane Doe",
    "email": "jane@example.com",
    "avatar_size_bytes": 120000
  },
  "output": {
    "status": "success",
    "validated": true
  }
}

AI uses this to:

4. Constraints: Guardrails for the AI

Constraints explicitly tell the AI what NOT to do.

Examples

Constraints ensure the AI produces code compliant with product rules.

5. NFRs: Non-Functional Requirements Are Critical for AI

Without NFRs, AI agents default to generic implementations that may be:

Structured NFR Examples

{"type":"nfr","expr":"latency_p95 <= 300ms"}
{"type":"nfr","expr":"must not log PII"}
{"type":"nfr","expr":"max_payload <= 1MB"}

6. Version Metadata — The Backbone of Traceability

Every user story should include:

ProdMoh automatically tracks versioning and updates the MCP stream so IDE agents can align requirements → tests → implementation.

Putting It All Together: A Complete AI User Story

{
  "id": "S-304",
  "title": "Update user profile",
  "intent": "User can update name, email, and avatar with validation and persistence.",
  "acceptance": [
    {"type":"predicate","expr":"response.status == 200"},
    {"type":"predicate","expr":"user.email matches /^[^@]+@[^@]+\\.[^@]+$/"},
    {"type":"predicate","expr":"avatar.size_bytes <= 5242880"}
  ],
  "examples": [
    {
      "input": {
        "name": "Jane Doe",
        "email": "jane@example.com",
        "avatar_size_bytes": 120000
      },
      "output": {
        "validated": true,
        "status": "success"
      }
    }
  ],
  "constraints": [
    "Avatar formats: JPG, PNG, WEBP",
    "Email must be unique"
  ],
  "nfr": [
    {"type":"nfr","expr":"latency_p95 <= 250ms"},
    {"type":"nfr","expr":"must not log PII"}
  ],
  "meta": {
    "version": "2025.12.1",
    "author": "pm@company.com"
  }
}

AI User Story Anti-Patterns to Avoid

❌ 1. Vague prose

AI cannot infer missing details.

❌ 2. Missing examples

Most hallucinations disappear when examples are added.

❌ 3. Mixing implementation details

Tell AI what should happen, not how.

❌ 4. Not specifying constraints

Constraints are non-negotiable in AI workflows.

Why ProdMoh Is the Ideal Platform for AI User Stories

ProdMoh ensures every user story is:

AI agents can fetch stories directly inside IDEs, eliminating feature drift and accelerating implementation.

Transformation

User stories stop being documentation and become executable specifications.

Conclusion

Writing user stories for AI agents is not about replacing agile practices—it’s about extending them into a world where AI participates directly in implementation.

By using structured intent, predicate-based acceptance criteria, examples, constraints, and NFRs, your AI agents can generate deterministic, correct, high-quality code on the first attempt.

ProdMoh makes this transformation practical by converting user stories into a machine-readable format accessible via MCP, closing the loop between product intent and engineering execution.
