Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.00378 |
| Opus 5 | $0.00010 | $0.00189 |
| Sonnet 5 | $0.00004 | $0.00076 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
gsp-first-playable 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 9d 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.
What it actually says
Game First Playable
You are the workflow for turning a prompt into a real first playable. This is a specialized mode, not the universal target for all game work.
Primary goal
Convert the user's idea into:
- a concrete first-playable spec,
- a narrow scope,
- a backend recommendation or comparison,
- a working vertical slice,
- a verification report.
Outputs
Follow the gsp-orchestrator output strategy:
- inline (default): present findings in conversation.
- minimal or full: write to
docs/game-studio/spec.md,docs/game-studio/backend-decision.md,docs/game-studio/ux-flow.md,docs/game-studio/architecture.md,docs/game-studio/plan.md,docs/game-studio/quality-report.md.
Use the shared template at ./shared/templates/first-playable-spec.md.
Workflow
- Compile the prompt into a minimal spec.
- Scope aggressively using
gsp-scope-guard. - Choose the backend profile with
gsp-backend-selector. - Design the first 30 seconds with
gsp-ux-flow-designer. - Bootstrap the loop with
gsp-loop-bootstrap. - Implement the thinnest vertical slice that proves the main fantasy.
- Verify with
gsp-playability-verifier. - Repair readability and feedback gaps with
gsp-screenshot-criticandgsp-hud-feedback-polish.
Important
Use this only when a minimal first-playable is truly the right target. If the user wants a stronger prototype or a production-grade feature, route elsewhere.
What ships with it
6 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.
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.

gsp-first-playable is a skill published in the GitHub repository mike007jd/game-superpowers (12 stars, last pushed 4mo ago), licensed MIT. It adds 21 tokens to every session and 378 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
setup-engine
Configure the project's game engine and version. Pins the engine in CLAUDE.md, detects knowledge gaps, and populates engine reference docs via WebSearch when the version is beyond the LLM's training data.
ux-design
Guided, section-by-section UX spec authoring for a screen, flow, or HUD. Reads game concept, player journey, and relevant GDDs to provide context-aware design guidance. Produces ux-spec.md (per screen/flow) or hud-design.md using the studio templates.
architecture-review
Validates completeness and consistency of the project architecture against all GDDs. Builds a traceability matrix mapping every GDD technical requirement to ADRs, identifies coverage gaps, detects cross-ADR conflicts, verifies engine compatibility consistency across all decisions, and produces a PASS/CONCERNS/FAIL…
prototype
Concept prototype — validate the core idea is worth designing before writing GDDs. Run right after /brainstorm and /setup-engine. Routes to HTML, Engine, or Paper path based on game type. Produces a throwaway build and a PROCEED/PIVOT/KILL verdict.
review-all-gdds
Holistic cross-GDD consistency and game design review. Reads all system GDDs simultaneously and checks for contradictions between them, stale references, ownership conflicts, formula incompatibilities, and game design theory violations (dominant strategies, economic imbalance, cognitive overload, pillar drift). Run…
localize
Full localization pipeline: scan for hardcoded strings, extract and manage string tables, validate translations, generate translator briefings, run cultural/sensitivity review, manage VO localization, test RTL/platform requirements, enforce string freeze, and report coverage.
