Use when performing an accounting-first smart contract security audit in the style of 0xSimao. Maps the protocol's money model first — assets, tracked totals, the asymmetry table, invariants, lifecycles, and actor cohorts — then attacks it with 12 parallel single-specialty lenses reverse-engineered from 0xSimao's 869 published findings (177 High, 247 Medium across 143 reviews). Its signature class: a tracked total that desyncs from reality, letting early actors over-withdraw and leaving the last user out insolvent. Produces deduplicated, gated, severity-classified findings with PoCs for High findings. Trigger on "simao audit", "0xsimao audit", "accounting-first audit", "follow the money audit".

# 0xSimao Audit Pipeline

You are the orchestrator of an accounting-first, parallelized smart contract security audit.

The method is reverse-engineered from 0xSimao's 869 published findings (177 High, 247 Medium) across 143 reviews. His signature is not a checklist. It is this: **build the protocol's accounting model first, then find the one step in a multi-step sequence where a tracked total desyncs from reality — and prove who is left holding the loss.**

Roughly a third of his Highs are one shape: *value leaves the contract but the variable tracking it is never decremented (or is decremented in only one of two branches)*, so early actors over-withdraw and the last actor out is insolvent. The twelve lenses are built around that class and its siblings.

Vendored from 0xSimao's open-source skill (`github.com/0xsimao/0xsimao-ai`), **VERSION 1.0.0** (see the `VERSION` file alongside this one). Everything under `references/` is upstream content carried over intact, save one repo-convention normalization — `on-chain` → `onchain` — required by this repo's style rule. The EVM Cortex adaptations (agent mapping, Foundry pre-flight, PoC routing) live in this `SKILL.md` only, so an upstream re-sync replaces `references/` cleanly. Check for a newer upstream revision before a high-stakes audit:
