assumption-stress-test

assumption-stress-test is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 47 tokens per session (494 once invoked), scanned A, original, Apache-2.0.

A structured review that finds assumptions, rates how much they matter and how likely they are to fail, then checks the most dangerous ones.

In plain words
What is it for?
Use it to review experiment plans, identify high-risk assumptions, check causal reasoning, and choose what to validate first.
Why use it?
It reduces the risk of making decisions that depend on fragile or untested beliefs.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

assumption-stress-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 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.

What it actually says

Assumption Stress Test

Systematically stress-test assumptions to find dangerous ones.

Operations

  • assumption-surfacing (shared) — extract all implicit assumptions
  • abp-vulnerability-classification — classify by load-bearing × vulnerable
  • clr-validation — validate causal logic of critical assumptions

Available SOPs

Shared: assumption-surfacing Subagent: abp-vulnerability-classification, clr-validation Import: paper-research

Execution Guidance

Surface all assumptions (shared SOP). Classify each by load-bearing × vulnerable matrix. Validate causal logic of most critical assumptions (High-Load × High-Vulnerable quadrant).

Minimum Yield

<HARD-GATE>
- assumptions surfaced: >= 5
- vulnerability classifications: >= 5
- CLR validations on critical assumptions: >= 2
- dangerous assumptions identified: >= 1
</HARD-GATE>

Available SOPs

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

SOP When to use
abp-vulnerability-classification Classify assumptions on 2 axes — load-bearing (how much conclusion depends on it) × vulnerable (how likely to be false). Focuses attention on High-Load × High-Vulnerable quadrant.
clr-validation Apply Goldratt's 8 Categories of Legitimate Reservation to validate causal claims. Tests clarity, existence, sufficiency, and logical integrity.
deep-insight-assumption-surfacing Systematically extract implicit assumptions from methods, frameworks, or arguments. Identifies what is taken for granted without explicit justification.
deep-insight-paper-research Full-text paper reading via three-pass Keshav method. Import of literature-engine/literature-research skill. Authoritative source for claims about paper content.

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.

assumption-stress-test is a skill published in the GitHub repository yogsoth-ai/de-anthropocentric-research-engine (462 stars, last pushed 3d ago), licensed Apache-2.0. It adds 47 tokens to every session and 494 once invoked, about $0.0002 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.
