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

full

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:

"Epic references [ADR-NNNN: title] but

docs/architecture/[adr-file].md

was not found. Check the filename in the epic's Governing ADRs list, or run

/architecture-decision

to create it. Cannot create stories until all referenced ADR files are present."

Do not proceed to Step 3 until all referenced ADR files are confirmed present.

Report: "Loaded epic [name], GDD [filename], [N] governing ADRs (all confirmed present), control manifest v[date]."

3. Classify Stories by Type

Story Type Classification — assign each story a type based on its acceptance criteria:

Story Type	Assign when criteria reference...
Logic	Formulas, numerical thresholds, state transitions, AI decisions, calculations
Integration	Two or more systems interacting, signals crossing boundaries, save/load round-trips
Visual/Feel	Animation behaviour, VFX, "feels responsive", timing, screen shake, audio sync
UI	Menus, HUD elements, buttons, screens, dialogue boxes, tooltips
Config/Data	Balance tuning values, data file changes only — no new code logic

Mixed stories: assign the type that carries the highest implementation risk. The type determines what test evidence is required before

/story-done

can close the story.

---

4. Decompose the GDD into Stories

For each GDD acceptance criterion:

1. Group related criteria that require the same core implementation
2. Each group = one story
3. Order stories: foundational behaviour first, edge cases last, UI last

Story sizing rule: one story = one focused session (~2-4 hours). If a group of criteria would take longer, split into two stories.

For each story, determine:

• GDD requirement: which acceptance criterion(ia) does this satisfy?
• TR-ID: look up in

  tr-registry.yaml

  . Use the stable ID. If no match, use

  TR-[system]-???

  and warn.
• Governing ADR: which ADR governs how to implement this?

  • Status: Accepted

    → embed normally

  • Status: Proposed

    → set story

    Status: Blocked

    with note: "BLOCKED: ADR-NNNN is Proposed — run

    /architecture-decision

    to advance it"
• Story Type: from Step 3 classification
• Engine risk: from the ADR's Knowledge Risk field

4b. QA Lead Story Readiness Gate

Review mode check — apply before spawning QL-STORY-READY:

• solo

  → skip. Note: "QL-STORY-READY skipped — Solo mode." Proceed to Step 5 (present stories for review).

• lean

  → skip (not a PHASE-GATE). Note: "QL-STORY-READY skipped — Lean mode." Proceed to Step 5 (present stories for review).

• full

  → spawn as normal.

After decomposing all stories (Step 4 complete) but before presenting them for write approval, spawn

qa-lead

via Task using gate QL-STORY-READY (

.claude/docs/director-gates.md

).

Pass: the full story list with acceptance criteria, story types, and TR-IDs; the epic's GDD acceptance criteria for reference.

Present the QA lead's assessment. For each story flagged as GAPS or INADEQUATE, revise the acceptance criteria before proceeding — stories with untestable criteria cannot be implemented correctly. Once all stories reach ADEQUATE, proceed.

After ADEQUATE: for every Logic and Integration story, ask the qa-lead to produce concrete test case specifications — one per acceptance criterion — in this format:

Test: [criterion text]
  Given: [precondition]
  When: [action]
  Then: [expected result / assertion]
  Edge cases: [boundary values or failure states to test]

For Visual/Feel and UI stories, produce manual verification steps instead:

Manual check: [criterion text]
  Setup: [how to reach the state]
  Verify: [what to look for]
  Pass condition: [unambiguous pass description]

These test case specs are embedded directly into each story's

## QA Test Cases

section. The developer implements against these cases. The programmer does not write tests from scratch — QA has already defined what "done" looks like.

---

5. Present Stories for Review

Before writing any files, present the full story list:

## Stories for Epic: [name]

Story 001: [title] — Logic — ADR-NNNN
  Covers: TR-[system]-001 ([1-line summary of requirement])
  Test required: tests/unit/[system]/[slug]_test.[ext]

Story 002: [title] — Integration — ADR-MMMM
  Covers: TR-[system]-002, TR-[system]-003
  Test required: tests/integration/[system]/[slug]_test.[ext]

Story 003: [title] — Visual/Feel — ADR-NNNN
  Covers: TR-[system]-004
  Evidence required: production/qa/evidence/[slug]-evidence.md

[N stories total: N Logic, N Integration, N Visual/Feel, N UI, N Config/Data]

Use

AskUserQuestion

:

• Prompt: "May I write these [N] stories to

  production/epics/[epic-slug]/

  ?"
• Options:

  [A] Yes — write all [N] stories

  /

  [B] Not yet — I want to review or adjust first

---

6. Write Story Files

For each story, write

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

:

# Story [NNN]: [title]

> **Epic**: [epic name]
> **Status**: Ready
> **Layer**: [Foundation / Core / Feature / Presentation]
> **Type**: [Logic | Integration | Visual/Feel | UI | Config/Data]
> **Manifest Version**: [date from control-manifest.md header]

## Context

**GDD**: `design/gdd/[filename].md`
**Requirement**: `TR-[system]-NNN`
*(Requirement text lives in `docs/architecture/tr-registry.yaml` — read fresh at review time)*

**ADR Governing Implementation**: [ADR-NNNN: title]
**ADR Decision Summary**: [1-2 sentence summary of what the ADR decided]

**Engine**: [name + version] | **Risk**: [LOW / MEDIUM / HIGH]
**Engine Notes**: [from ADR Engine Compatibility section — post-cutoff APIs, verification required]

**Control Manifest Rules (this layer)**:
- Required: [relevant required pattern]
- Forbidden: [relevant forbidden pattern]
- Guardrail: [relevant performance guardrail]

---

## Acceptance Criteria

*From GDD `design/gdd/[filename].md`, scoped to this story:*

- [ ] [criterion 1 — directly from GDD]
- [ ] [criterion 2]
- [ ] [performance criterion if applicable]

---

## Implementation Notes

*Derived from ADR-NNNN Implementation Guidelines:*

[Specific, actionable guidance from the ADR. Do not paraphrase in ways that
change meaning. This is what the programmer reads instead of the ADR.]

---

## Out of Scope

*Handled by neighbouring stories — do not implement here:*

- [Story NNN+1]: [what it handles]

---

## QA Test Cases

*Written by qa-lead at story creation. The developer implements against these — do not invent new test cases during implementation.*

**[For Logic / Integration stories — automated test specs]:**

- **AC-1**: [criterion text]
  - Given: [precondition]
  - When: [action]
  - Then: [assertion]
  - Edge cases: [boundary values / failure states]

**[For Visual/Feel / UI stories — manual verification steps]:**

- **AC-1**: [criterion text]
  - Setup: [how to reach the state]
  - Verify: [what to look for]
  - Pass condition: [unambiguous pass description]

---

## Test Evidence

**Story Type**: [type]
**Required evidence**:
- Logic: `tests/unit/[system]/[story-slug]_test.[ext]` — must exist and pass
- Integration: `tests/integration/[system]/[story-slug]_test.[ext]` OR playtest doc
- Visual/Feel: `production/qa/evidence/[story-slug]-evidence.md` + sign-off
- UI: `production/qa/evidence/[story-slug]-evidence.md` or interaction test
- Config/Data: smoke check pass (`production/qa/smoke-*.md`)

**Status**: [ ] Not yet created

---

## Dependencies

- Depends on: [Story NNN-1 must be DONE, or "None"]
- Unlocks: [Story NNN+1, or "None"]

Also update

production/epics/[epic-slug]/EPIC.md

Replace the "Stories: Not yet created" line with a populated table:

## Stories

| # | Story | Type | Status | ADR |
|---|-------|------|--------|-----|
| 001 | [title] | Logic | Ready | ADR-NNNN |
| 002 | [title] | Integration | Ready | ADR-MMMM |

---

7. After Writing

Use

AskUserQuestion

to close with context-aware next steps:

Check:

• Are there other epics in

  production/epics/

  without stories yet? List them.
• Is this the last epic? If so, include

  /sprint-plan

  as an option.

Widget:

• Prompt: "[N] stories written to

  production/epics/[epic-slug]/

  . What next?"
• Options (include all that apply):

  • [A] Start implementing — run /story-readiness [first-story-path]

    (Recommended)

  • [B] Create stories for [next-epic-slug] — run /create-stories [slug]

    (only if other epics have no stories yet)

  • [C] Plan the sprint — run /sprint-plan

    (only if all epics have stories)

  • [D] Stop here for this session

Note in output: "Work through stories in order — each story's

Depends on:

field tells you what must be DONE before you can start it."

Collaborative Protocol

1. Read before presenting — load all inputs silently before showing the story list
2. Ask once — present all stories for the epic in one summary, not one at a time
3. Warn on blocked stories — flag any story with a Proposed ADR before writing
4. Ask before writing — get approval for the full story set before writing files
5. No invention — acceptance criteria come from GDDs, implementation notes from ADRs, rules from the manifest
6. Never start implementation — this skill stops at the story file level

After writing (or declining):

• Verdict: COMPLETE — [N] stories written to

  production/epics/[epic-slug]/

  . Run

  /story-readiness

  →

  /dev-story

  to begin implementation.
• Verdict: BLOCKED — user declined. No story files written.
