Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00090 | $0.01325 |
| Opus 5 | $0.00045 | $0.00662 |
| Sonnet 5 | $0.00018 | $0.00265 |
| Haiku 4.5 | $0.00009 | $0.00133 |
Grade A, and why
circular-validation-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 6d 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.

How it starts
The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Circular Validation Audit
A pre-build gate for any validator we are about to construct — a sandbox, simulation, or benchmark that is supposed to verify a theory. The catastrophic failure mode: we build the validator using the theory's own assumptions as the validator's ground-truth machinery, run the theory's method on the validator's output, and celebrate when it "recovers" the truth — but the recovery was guaranteed by construction, not by the theory being right. The PASS carries zero evidential weight. This is the single most expensive mistake available, because a circular validator can burn enormous compute producing confident, meaningless confirmations. So this audit runs FIRST, on the validator DESIGN, before a line of it is built.
The core risk, stated precisely
A validator V tests a theory T by: generating data D from a ground-truth generator G, running T's recovery method R on D, and checking if R(D) matches G's hidden truth. The test is non-circular only if G is NOT itself an instance of T's central assumptions. If G is built from the same functional factorization / the same noise law / the same mechanism that T claims to discover, then "R recovers G" is a tautology: we encoded the answer into the question. The audit's job is to find every place where G secretly contains T.
Non-circularity matrix (the central artifact)
Rows = the theory's load-bearing claims/assumptions (the ones the validator is meant to test). Columns = the validator's ground-truth construction choices (how each mechanism is implemented, what functional forms or noise laws the generator uses, what intervention semantics the validator actually applies).
Each cell asks: does this construction choice ASSUME this claim?
| validator: construction choice 1 | validator: construction choice 2 | validator: construction choice 3 | … | |
|---|---|---|---|---|
| claim: load-bearing claim A | ? | ? | ? | ? |
| claim: load-bearing claim B | ? | ? | ? | ? |
| claim: load-bearing claim C | ? | ? | ? | ? |
| … | ? | ? | ? | ? |
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.

circular-validation-audit is a skill published in the GitHub repository yogsoth-ai/de-anthropocentric-research-engine (449 stars, last pushed today), licensed Apache-2.0. It adds 90 tokens to every session and 1,325 once invoked, about $0.0005 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.
