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 | $0.00028 | $0.00466 |
| Opus 5 | $0.00014 | $0.00233 |
| Sonnet 5 | $0.00006 | $0.00093 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
gsp-web-2d-specialist 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 11d 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 Web 2D Specialist
Goal
Turn a backend decision into concrete browser 2D implementation guidance without collapsing the whole system into library fandom.
Outputs
Follow the gsp-orchestrator output strategy:
- inline (default): present 2D implementation guidance in conversation.
- minimal or full: write or update
docs/game-studio/backend-implementation.md.
Use when
- the chosen backend profile is
web-2d-ui-firstorweb-2d-world-first - the project is browser-first and needs sharper implementation guidance
- the team wants a concrete 2D route without losing stack-neutral top-level planning
Use
./shared/reference/backend-profiles.md./shared/reference/browser-2d-specialist.md./shared/checklists/ui-ux-hard-rules.md
Cover
- recommended route archetype and why
- simulation state vs presentation state split
- HUD layer decision and whether a dedicated UI layer is needed
- action-state, fail-state, and restart-state handling
- mobile and desktop input expectations
- procedural-art constraints when relevant
- top implementation risks
Important
Be concrete about architecture patterns, layering, and tradeoffs.
Do not pretend the backend is irrelevant once the route is chosen.
Do not begin implementation if the gameplay shape is still ambiguous.
If the request is primarily about Douyin H5 Interactive platform shell, portrait H5 delivery shape, app-shell structure, or requests phrased as 抖音互动空间 / 抖音互动H5, route through gsp-douyin-h5 first.
Before coding, confirm or inherit:
- camera / presentation model
- movement grammar
- obstacle or enemy grammar
- fail and restart loop
- HUD priority
For archetypes like runner, platformer, survivor, or breakout, lock the subtype first.
Example: runner alone is not specific enough. Decide whether it is lane-based, side-view platform, or top-down dodge before implementation.
What ships with it
8 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-web-2d-specialist is a skill published in the GitHub repository mike007jd/game-superpowers (12 stars, last pushed 4mo ago), licensed MIT. It adds 28 tokens to every session and 466 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.
