assumption-audit

assumption-audit is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 37 tokens per session (685 once invoked), scanned A, original, Apache-2.0.

A structured audit of the assumptions behind a method, theory, or research gap, focusing on assumptions that carry much of the conclusion.

In plain words
What is it for?
Use it to surface assumptions, classify their risk, check causal logic, and produce an audit report for research or planning.
Why use it?
It helps expose important beliefs that are both weakly supported and easy to overlook.

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-audit 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.

Assumption Audit

Systematically audit assumptions underlying a method, theory, or gap.

When to Use

Need to identify which hidden assumptions are most dangerous — load-bearing yet unexamined.

web-search 30 27–33
web-research 10 9–11

Available Tactics

  • assumption-stress-test

Available SOPs

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

Execution Guidance

Surface all assumptions (shared SOP), classify by vulnerability (ABP), validate causal logic (CLR 8-check). Focus on load-bearing + non-explicit assumptions.

Output Format

Assumption Audit Report — assumption inventory, vulnerability matrix, CLR validation results, priority list for challenging.

Available Tactics

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

Tactic When to use
assumption-stress-test Systematic stress testing of assumptions — surface, classify by vulnerability, attack, assess fragility. Combines assumption-surfacing (shared), abp-vulnerability-classification, and clr-validation SOPs.

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.

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-audit is a skill published in the GitHub repository yogsoth-ai/de-anthropocentric-research-engine (456 stars, last pushed yesterday), licensed Apache-2.0. It adds 37 tokens to every session and 685 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.
