assumption-criticality

assumption-criticality is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 28 tokens per session (628 once invoked), scanned A, original, Apache-2.0.

An analysis method that tests each assumption by pretending it is false and measuring how much the final conclusion changes.

In plain words
What is it for?
Use it to rank assumptions by importance when evaluating research findings, arguments, or decisions.
Why use it?
It shows which assumptions are merely background details and which ones determine the result.

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-criticality 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.

Execution Guidance

Extract assumptions, define negation for each, re-derive conclusions under negated assumption, measure how much the conclusion changes. Rank by conclusion sensitivity.

Available Tactics

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

Tactic When to use
deep-insight-assumption-perturbation One-at-a-time assumption perturbation — extract assumptions, define negations, re-derive conclusions under each negation, measure sensitivity. Identifies which assumptions are load-bearing.

Available SOPs

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

SOP When to use
conclusion-sensitivity-measurement Quantify how much conclusions change across all assumption negations and produce a sensitivity ranking.
deep-insight-assumption-extraction Systematically extract all assumptions (stated, implicit, boundary, mathematical, practical) from a method or model.
negation-definition Define strongest plausible alternatives (negations) for each assumption to enable perturbation analysis.
re-derivation Re-derive conclusions under a negated assumption, tracking where the derivation diverges from the original.

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-criticality 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 28 tokens to every session and 628 once invoked, about $0.0001 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.
