create-stories

create-stories is a skill for Claude Code, Codex from Donchitos/Claude-Code-Game-Studios. It costs 65 tokens per session (3,581 once invoked), scanned A, original, MIT.

A planning tool that breaks one technical epic into small, implementable pieces of work called stories. Each story connects the work to a design requirement, an architecture decision, acceptance checks, and test evidence.

In plain words
What is it for?
Use it after creating an epic to produce the story files developers will implement and verify.
Why use it?
It prevents developers from having to infer requirements or testing expectations from scattered design documents. The result is work that can be picked up and completed in a focused session.

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

create-stories 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Stories

A story is a single implementable behaviour — small enough to complete in one focused session, self-contained, and fully traceable to a GDD requirement and an ADR decision. Stories are what developers pick up. Epics are what architects define.

Run this skill per epic, not per layer. Run it for Foundation epics first, then Core, and so on — matching the dependency order.

Output: production/epics/[epic-slug]/story-NNN-[slug].md files

Previous step: /create-epics [system] Next step after stories exist: /story-readiness [story-path] then /dev-story [story-path]


1. Parse Argument

Extract --review [full|lean|solo] if present and store as the review mode override for this run. If not provided, read production/review-mode.txt (default lean if missing). This resolved mode applies to all gate spawns in this skill — apply the check pattern from .claude/docs/director-gates.md before every gate invocation.

  • /create-stories [epic-slug] — e.g. /create-stories combat
  • /create-stories production/epics/combat/EPIC.md — full path also accepted
  • No argument — ask: "Which epic would you like to break into stories?" Glob production/epics/*/EPIC.md and list available epics with their status.

2. Load Everything for This Epic

Read in full:

  • production/epics/[epic-slug]/EPIC.md — epic overview, governing ADRs, GDD requirements table
  • The epic's GDD (design/gdd/[filename].md) — read all 8 sections, especially Acceptance Criteria, Formulas, and Edge Cases
  • All governing ADRs listed in the epic — read the Decision, Implementation Guidelines, Engine Compatibility, and Engine Notes sections
  • docs/architecture/control-manifest.md — extract rules for this epic's layer; note the Manifest Version date from the header
  • docs/architecture/tr-registry.yaml — load all TR-IDs for this system

ADR existence validation: After reading the governing ADRs list from the epic, confirm each ADR file exists on disk. If any ADR file cannot be found, stop immediately before decomposing any story:

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.
