gate-check

gate-check is a skill for Claude Code from CodePhobiia/claude-roblox-game-studio. It costs 29 tokens per session (954 once invoked), scanned A, original, MIT.

A checklist for deciding whether a project is ready to move from one production stage to the next. It covers stages such as planning, production, polishing, and launch.

In plain words
What is it for?
Use it to review game projects before production, polish, or release, checking items such as the core gameplay loop, planned systems, bugs, performance, and team capacity.
Why use it?
It prevents teams from moving forward while important designs, features, tests, performance work, or bug fixes are still missing. The review makes readiness an explicit decision instead of an ongoing guess.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

gate-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 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.

/gate-check — Stage Gate Review

Delegate to: producer (with technical-director, qa-lead, creative-director for respective areas)

Purpose

Stage gates force a deliberate decision about whether to move to the next production phase. Without gates, projects drift — always "almost ready" to start production, or "almost ready" to ship.

Stages

Pre-production → Production

Gate criteria:

  • Master GDD exists and reviewed
  • Creative pillars defined (3-5, 1 phrase each)
  • Core loop defined (30s / 5min / session / meta)
  • Target audience identified
  • Monetization strategy drafted
  • Target metrics set (retention, session, revenue if applicable)
  • Tech stack decided (sync tool, UI framework, packages)
  • Systems-index exists with priority
  • 2-3 top systems have detailed GDDs
  • Prototype or proof-of-concept validates core loop
  • Team capacity matches estimated scope (or scope cut accordingly)

Production → Polish

Gate criteria:

  • All core systems implemented (from systems-index P0/P1)
  • Game is playable end-to-end (intro → core loop → meta)
  • No S0 bugs open
  • All planned features either done or explicitly cut
  • Basic performance targets met (30 FPS mobile, server heartbeat < 33ms)
  • Security audit has been run at least once
  • DataStore schema is frozen (no more breaking changes)
  • Analytics events implemented
  • At least one external playtest (not just devs) completed

Polish → Live (Launch Ready)

Gate criteria:

  • Zero S0 bugs
  • Zero S1 bugs in critical paths
  • Performance targets exceeded on target devices
  • Security audit passed with no Critical findings
  • Content policy review passed
  • All launch marketing materials ready
  • Community channels active
  • Rollback plan tested
  • Soft launch retention > target (D1 > 20%, ideally > 25%)
  • Server costs projected and manageable
  • Team ready for launch support

Live → Live Service Optimization

Gate criteria (do we continue investing?):

  • Retention trending up or stable
  • Revenue meets minimum threshold
  • Community engaged (growing Discord, positive reviews)
  • Technical debt manageable
  • Team has capacity for sustained live-ops

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.
