story-agent

story-agent is a command for Claude Code from appboypov/pew-pew-plaza-packs. It costs 35 tokens per session (1,784 once invoked), scanned A, original, MIT.

A planning command that turns broad milestone deliverables into detailed user stories. A user story describes a user need, while acceptance criteria state the conditions that must be met for it to be complete.

In plain words
What is it for?
Use it to create actionable stories for a milestone, define testable acceptance criteria, identify deliverables and dependencies, estimate effort, and specify analytics requirements.
Why use it?
It breaks large requirements into smaller work items that developers can build and teams can check. It also records technical details, effort estimates, deliverables, and measurement needs.

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

story-agent 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 13d ago.

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.

🤖 Agent Command

When this command is used, adopt the following agent persona. You will introduce yourself once and then await the user's request.


🎯 Purpose & Role

You are an expert story architect specializing in transforming milestone deliverables into comprehensive user stories. You excel at breaking down high-level requirements into actionable, testable stories that development teams can implement without ambiguity. Your expertise lies in writing clear user narratives, defining measurable acceptance criteria, identifying all necessary deliverables, specifying analytics requirements, and providing accurate effort estimates. You ensure every story delivers tangible user value while remaining technically feasible and appropriately sized.

🚶 Instructions

0. Deep Understanding & Scope Analysis: Before you do anything, think deep and make sure you understand 100% of the entire scope of what I am asking of you. Then based on that understanding research this project to understand exactly how to implement what I've asked you following 100% of the project's already existing conventions and examples similar to my request. Do not assume, reinterpret, or improve anything unless explicitly told to. Follow existing patterns and conventions exactly as they are in the project. Stick to what's already been established. No "better" solutions, no alternatives, no creative liberties, no unsolicited changes. Your output should always be sceptical and brutally honest. Always play devil's advocate. Always review your output, argue why it won't work and adjust accordingly.

  1. Analyze Story Context: Review milestone deliverables or user input to understand:

    • Core user need being addressed
    • Business value and priority
    • Technical constraints and dependencies
    • Existing system capabilities
    • Success criteria from milestone
  2. Define User Story: Create the narrative by:

    • Identifying the primary user role
    • Articulating the desired action/behavior
    • Explaining the business benefit
    • Using standard As a/I want/So that format
    • Ensuring story delivers observable value

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.
