user-story

user-story is a skill for Claude Code, Codex from getcrew44/crew44. It costs 35 tokens per session (2,546 once invoked), scanned A, original, MIT.

A guide for writing user stories in the format “As a… I want to… so that…” and adding Gherkin acceptance criteria. Gherkin is a plain-language format that describes conditions and expected outcomes in Given, When, and Then steps.

In plain words
What is it for?
Use it to turn user needs into development-ready backlog items with a defined user, desired outcome, and verifiable scenarios.
Why use it?
Unclear requirements can leave product and engineering with different understandings of what to build. Structured stories connect a user need to a clear, testable result.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

user-story scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/user-story-template.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Purpose

Create clear, concise user stories that combine Mike Cohn's user story format with Gherkin-style acceptance criteria. Use this to translate user needs into actionable development work that focuses on outcomes, ensures shared understanding between product and engineering, and provides testable success criteria.

This is not a feature spec—it's a conversation starter that captures who benefits, what they're trying to do, why it matters, and how you'll know it works.

Key Concepts

The Mike Cohn + Gherkin Format

A user story combines:

Use Case (Mike Cohn format):

  • As a [user persona/role]
  • I want to [action to achieve outcome]
  • so that [desired outcome]

Acceptance Criteria (Gherkin format):

  • Scenario: [Brief description of the scenario]
  • Given: [Initial context or preconditions]
  • and Given: [Additional preconditions]
  • When: [Event that triggers the action]
  • Then: [Expected outcome]

Why This Structure Works

  • User-centric: Forces focus on who benefits and why
  • Outcome-focused: "So that" emphasizes the value delivered, not just the action
  • Testable: Gherkin acceptance criteria are concrete and verifiable
  • Conversational: Story is the opening for discussion, not the final spec
  • Shared language: Product, engineering, and QA all understand the format

Anti-Patterns (What This Is NOT)

  • Not a task: "As a developer, I want to refactor the database" (this is a tech task, not user value)
  • Not a feature list: "I want dashboards, reports, and analytics" (this is too big—needs splitting)
  • Not vague: "I want a better experience" (unmeasurable, no clear outcome)
  • Not a contract: Stories are placeholders for conversation, not locked-in specs

When to Use This

  • Translating user needs into development work
  • Backlog grooming and sprint planning
  • Communicating value to engineering and design
  • Ensuring testable acceptance criteria exist before development

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
