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 | $0.00618 | $0.00618 |
| Opus 5 | $0.00309 | $0.00309 |
| Sonnet 5 | $0.00124 | $0.00124 |
| Haiku 4.5 | $0.00062 | $0.00062 |
Grade A, and why
nemesis-auditor CLAUDE.md 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 12d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nemesis Agent
What This Is
NEMESIS is an iterative deep-logic security audit agent for Claude Code. It orchestrates two sub-agents in an alternating feedback loop to find bugs that neither can catch alone. Language-agnostic -- works on Solidity, Move, Rust, Go, C++, Python, TypeScript, or any codebase.
How to Use
- Copy the
.claude/folder into your target project (or run Claude Code in this directory) - Start Claude Code:
claude - Type
/nemesisto launch the full iterative audit
Available Commands
| Command | Action |
|---|---|
/nemesis |
Full Nemesis audit (iterative back-and-forth until convergence) |
/nemesis --pass1 |
Pass 1 only -- run full Feynman Auditor |
/nemesis --pass2 |
Pass 2 only -- run full State Inconsistency Auditor on existing Pass 1 output |
/nemesis --continue |
Continue iterating from where the last pass left off |
/nemesis --contract [name] |
Full Nemesis audit on a single contract |
/feynman |
Run the Feynman Auditor standalone |
/state-audit |
Run the State Inconsistency Auditor standalone |
How It Works
PASS 1: Feynman Auditor (full run)
Questions every line. Exposes assumptions. Flags suspects.
| feed forward |
PASS 2: State Inconsistency Auditor (full run, enriched by Pass 1)
Maps coupled state. Finds mutation gaps. Uses Feynman suspects as targets.
| feed forward |
PASS 3+: Alternating targeted passes until convergence
Each pass interrogates the previous pass's new findings.
Max 6 passes. Nothing survives.
Agent Composition
When /nemesis is triggered, the nemesis-auditor orchestrator automatically loads and runs:
-
Feynman Auditor (
.claude/skills/feynman-auditor/SKILL.md) -- Deep business logic bug finder using the Feynman technique. Questions every line, every ordering choice, every guard presence/absence. -
State Inconsistency Auditor (
.claude/skills/state-inconsistency-auditor/SKILL.md) -- Maps every coupled state pair, every mutation path, and every gap where one side updates without the other.
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.

nemesis-auditor CLAUDE.md is an instructions file published in the GitHub repository 0xiehnnkta/nemesis-auditor (243 stars, last pushed 5mo ago), licensed MIT. It adds 618 tokens to every session, about $0.0031 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 2026-08-30.
