stress-test-saturation-detection

stress-test-saturation-detection is a skill for Claude Code, Codex from yogsoth-ai/stress-test. It costs 34 tokens per session (347 once invoked), scanned A, original, Apache-2.0.

A validation check that determines whether repeated testing is still finding genuinely new weaknesses. It marks the process as saturated after several low-novelty rounds.

In plain words
What is it for?
Use it to track novelty across validation iterations and decide when a testing campaign can stop.
Why use it?
It helps decide when further testing is no longer uncovering meaningful failure modes.

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

stress-test-saturation-detection 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 7d 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

Saturation Detection

Determines whether validation has reached saturation — no new weaknesses being discovered.

Execution

Subagent — spawned via subagent-spawning/spawn-agent.

Why Subagent

Requires comparing accumulated findings against latest iteration to compute novelty ratio — dedicated context prevents contamination from ongoing analysis.

Input

  • findings_accumulated: Running list of all findings from current campaign
  • latest_iteration_findings: Findings from the most recent iteration

Output

  • verdict: saturated | not-saturated
  • confidence: 0.0–1.0
  • novelty_ratio: percentage of latest findings that are genuinely new
  • reasoning: explanation of verdict

Hard Constraint

≥3 consecutive iterations with <10% novel findings → saturated

Budget

One unit = one saturation check. Called after each tactic iteration.

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP When to use
spawn-agent Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent.
Files

What ships with it

1 file 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.

Changes

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.
