soak-test

soak-test is a skill for Claude Code from bullish0x/GameStudio. It costs 54 tokens per session (2,360 once invoked), scanned A, a copy of soak-test, MIT.

A protocol for testing a game during a long, continuous play session.

In plain words
What is it for?
Use it to plan sessions lasting from about 30 minutes to several hours and record what happens over time.
Why use it?
Short tests can miss memory leaks, gradual performance loss, repeated-action bugs, player fatigue, and the point where content becomes repetitive.

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

soak-test 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 5d 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.

Soak Test

A soak test (also called an endurance test) is an extended play session run with specific observation goals. Unlike a smoke check (broad critical path, ~10 min) or a single-feature playtest (~30 min), a soak test runs for 30 minutes to several hours to surface:

  • Memory leaks — gradual heap growth that only appears after scene transitions
  • Performance drift — frame time degradation that worsens over time
  • State accumulation bugs — issues that only appear after N repetitions of a mechanic (inventory full, score overflow, AI state corruption)
  • Fun fatigue — mechanics that feel good in a first session but grow repetitive over extended play
  • Content exhaustion — the point where players run out of novel content

This skill generates the observation protocol and analysis harness — the human does the actual playing.

Output: production/qa/soak-test-[date]-[duration].md

When to run:

  • Polish phase — before /gate-check release
  • After fixing a memory or stability issue (regression soak)
  • When extended play has not been formally tracked

1. Parse Arguments

Duration (default: 1h):

  • 30m — short soak; suitable for testing a single mechanic or scene
  • 1h — standard soak; covers most common leak categories
  • 2h — extended soak; recommended for first full Polish soak
  • 4h — deep soak; required for games with long session design (RPGs, sims)

Focus (default: all):

  • memory — focus on heap size, object count, leak patterns
  • stability — focus on crash/freeze/hang detection
  • balance — focus on fun fatigue, content exhaustion, difficulty perception
  • all — all of the above

2. Load Context

Read:

  • .agents/docs/technical-preferences.md — engine (for engine-specific memory monitoring guidance), performance budgets (memory ceiling, target FPS)
  • design/gdd/game-concept.md — intended session length (for comparison against soak duration), core loop description
  • Most recent file in production/playtests/ — prior playtest findings (to avoid re-documenting known issues)
  • Most recent file in production/qa/qa-plan-*.md — current sprint test coverage (to understand what has been formally tested vs. what the soak covers)

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.
