# Skill Flow Diagrams
Visual maps of how skills chain together across the 7 development phases.
These show what runs before and after each skill, and what artifacts flow between them.

## Full Pipeline Overview (Zero to Ship)
```

## Skill Chain: /design-system in Detail
How a single GDD gets authored, reviewed, and handed to architecture:
```
systems-index.md (input)
game-concept.md (input)
upstream GDDs (input, if any)
/design-system [name]
├── Pre-check: feasibility table + engine risk flags
├── Section cycle × 8:
│ question → options → decision → draft → approval → WRITE
│ [each section written to file immediately after approval]
└── Output: design/gdd/[system].md (complete, all 8 sections)
/design-review design/gdd/[system].md
├── APPROVED → mark DONE in systems-index, proceed to next system
├── NEEDS REVISION → agent shows specific issues, re-enter section cycle
└── MAJOR REVISION → significant redesign needed before next system
▼ (after all MVP GDDs + cross-review)
/review-all-gdds
└── Output: gdd-cross-review-[date].md
```
---
## Skill Chain: UX / UI Pipeline in Detail
UX specs are authored in Phase 4 (Pre-Production), before epics are written, so
that story acceptance criteria can reference specific UX artifacts.
```
design/gdd/*.md (UI/UX requirements extracted)
design/player-journey.md (emotional arc, if authored)
/ux-design hud → design/ux/hud.md
/ux-design screen [name] → design/ux/screens/[name].md
/ux-design patterns → design/ux/interaction-patterns.md
/ux-review design/ux/
├── APPROVED → UX specs ready, proceed to /create-epics
├── NEEDS REVISION → blocking issues listed → fix → re-run review
└── MAJOR REVISION → fundamental UX problems → redesign before epics
▼ (after APPROVED — in Phase 5 when implementing UI features)
/team-ui
├── Phase 1: /ux-design (if any specs still missing) + /ux-review
├── Phase 2: visual design (art-director)
├── Phase 3: layout implementation (ui-programmer)
├── Phase 4: accessibility audit (accessibility-specialist)
└── Phase 5: final review
Note: /ux-design and /ux-review belong in Phase 4 (Pre-Production).
/team-ui belongs in Phase 5 (Production) when a UI feature is being built.
```
---
## Skill Chain: Dev Story Flow in Detail
How a story moves from backlog to closed:
```
/story-readiness [story]
├── READY → Status: ready-for-dev → pick up for implementation
├── NEEDS WORK → agent shows specific gaps → resolve → re-run readiness
└── BLOCKED → ADR still Proposed, or upstream story incomplete
▼ (after READY)
/dev-story [story]
├── Reads: story file, linked GDD requirement, ADR decisions, control manifest
├── Routes to: gameplay-programmer / engine-programmer / ui-programmer / etc.
└── Implementation begins
▼ (optional, during/after implementation)
/code-review → architectural review of changeset
/scope-check → verify no scope creep vs. original story criteria
/test-evidence-review → validate test files and manual evidence quality
/story-done [story]
├── COMPLETE → Status: Complete, sprint-status.yaml updated, next story surfaced
├── COMPLETE WITH NOTES → complete but some criteria deferred (logged)
└── BLOCKED → acceptance criteria cannot be verified → investigate blocker
```
---
## Skill Chain: Story Lifecycle (Backlog to Closed)
How a story gets from backlog to closed (summary view):
```
/create-epics [layer]
└── Output: production/epics/[slug]/EPIC.md
/create-stories [epic-slug]
└── Output: production/epics/[slug]/story-NNN-[slug].md
(Status: Ready or Blocked if ADR is Proposed)
/story-readiness [story]
├── READY → /dev-story → implement → /story-done
├── NEEDS WORK → resolve gaps → re-run
└── BLOCKED → fix upstream dependency first
```
---
## Skill Chain: QA Pipeline in Detail
```
[Phase 4 — one-time infrastructure setup]
/test-setup ────────────────────────────────────────────────────► test framework scaffolded + CI/CD wired
/test-helpers ──────────────────────────────────────────────────► tests/helpers/[engine].gd (GDUnit4, NUnit, etc.)
[Phase 5 — per-sprint QA cycle]
/qa-plan [sprint or feature]
├── Reads: story files, GDDs, acceptance criteria
├── Classifies each story by test type:
│ Logic → automated unit test (BLOCKING)
│ Integration → integration test or documented playtest (BLOCKING)
│ Visual/Feel → screenshot + lead sign-off (ADVISORY)
│ UI → manual walkthrough or interaction test (ADVISORY)
│ Config/Data → smoke check (ADVISORY)
└── Output: production/qa/qa-plan-sprint-NN.md
/smoke-check
├── PASS → QA hand-off cleared
└── FAIL → block sprint close → fix critical paths first
/regression-suite
└── Coverage gaps + list of fixed bugs without regression tests
/test-evidence-review
└── Validates evidence quality, not just existence
▼ (if CI run history available)
/test-flakiness
└── Flaky test report + fix recommendations
[Phase 6 — extended stability testing]
/soak-test ─────────────────────────────────────────────────────► soak test protocol + observed results
/team-qa ───────────────────────────────────────────────────────► full QA cycle sign-off for release gate
[Ongoing — bug management]
/bug-report ────────────────────────────────────────────────────► production/qa/bugs/bug-NNN.md
/bug-triage ────────────────────────────────────────────────────► open bugs re-prioritized + assigned
[Meta — harness validation]
/skill-test [lint|spec|catalog] ────────────────────────────────► skill file structural + behavioral check
```

## Brownfield Onboarding Flow
For projects with existing work (use `/start` option D or run directly):
```
/project-stage-detect → stage detection report
/adopt
├── Phase 1: detect what exists
├── Phase 2: FORMAT audit (not just existence)
├── Phase 3: classify gaps (BLOCKING / HIGH / MEDIUM / LOW)
├── Phase 4: ordered migration plan
├── Phase 5: write docs/adoption-plan-[date].md
└── Phase 6: fix most urgent gap inline (optional)
/design-system retrofit [path] → fills missing GDD sections
/architecture-decision retrofit [path] → fills missing ADR sections
/gate-check → where are you in the pipeline?
```
