Claude Code Game Studios is a setup that organizes Claude Code into a coordinated game-development team of specialized AI agents. It supports game projects across design, programming, art, audio, narrative, quality assurance, and production, with skills and workflows for coordinating that work.
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 | $0.00052 | $0.01069 |
| Opus 5 | $0.00026 | $0.00535 |
| Sonnet 5 | $0.00010 | $0.00214 |
| Haiku 4.5 | $0.00005 | $0.00107 |
Grade A, and why
scope-check 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scope Check
This skill is read-only — it reports findings but writes no files.
Compares original planned scope against current state to detect, quantify, and triage scope creep.
Argument: $ARGUMENTS[0] — feature name, sprint number, or milestone name.
Phase 1: Find the Original Plan
Locate the baseline scope document for the given argument:
- Feature name → read
design/gdd/[feature].mdor matching file indesign/ - Sprint number (e.g.,
sprint-3) → readproduction/sprints/sprint-03.mdor similar - Milestone → read
production/milestones/[name].md
If the document is not found, report the missing file and stop. Do not proceed without a baseline to compare against.
Phase 2: Read the Current State
Check what has actually been implemented or is in progress:
- Scan the codebase for files related to the feature/sprint
- Read git log for commits related to this work (
git log --oneline --since=[start-date]) - Check for TODO/FIXME comments that indicate unfinished scope additions
- Check active sprint plan if the feature is mid-sprint
Phase 3: Compare Original vs Current Scope
Produce the comparison report:
## Scope Check: [Feature/Sprint Name]
Generated: [Date]
### Original Scope
[List of items from the original plan]
### Current Scope
[List of items currently implemented or in progress]
### Scope Additions (not in original plan)
| Addition | Source | When | Justified? | Effort |
|----------|--------|------|------------|--------|
| [item] | [commit/person] | [date] | [Yes/No/Unclear] | [S/M/L] |
### Scope Removals (in original but dropped)
| Removed Item | Reason | Impact |
|-------------|--------|--------|
| [item] | [why removed] | [what's affected] |
### Bloat Score
- Original items: [N]
- Current items: [N]
- Items added: [N] (+[X]%)
- Items removed: [N]
- Net scope change: [+/-N] ([X]%)
### Risk Assessment
- **Schedule Risk**: [Low/Medium/High] — [explanation]
- **Quality Risk**: [Low/Medium/High] — [explanation]
- **Integration Risk**: [Low/Medium/High] — [explanation]
### Recommendations
1. **Cut**: [Items that should be removed to stay on schedule]
2. **Defer**: [Items that can move to a future sprint/version]
3. **Keep**: [Additions that are genuinely necessary]
4. **Flag**: [Items that need a decision from producer/creative-director]
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.

scope-check is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (24,822 stars, last pushed 3mo ago), licensed MIT. It adds 52 tokens to every session and 1,069 once invoked, about $0.0003 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 2026-09-03.
