aetherlang-karpathy-skill

aetherlang-karpathy-skill is a skill for Claude Code, Codex from zrtch/awesome-skills. It costs 90 tokens per session (1,709 once invoked), scanned A, original, MIT.

An API connector for running AetherLang Omega agent workflows on a hosted service. It supports ten node types, including planning, coding, critique, routing, memory, loops, and parallel work.

In plain words
What is it for?
Use it to design and run multi-step AI workflows through the AetherLang API, such as planning a task, checking an answer, routing work, or processing steps in parallel.
Why use it?
It lets an agent use these workflow steps without running the engine or code on the developer’s computer. Requests send only the query and workflow code to the remote API.

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

aetherlang-karpathy-skill scanned grade A with 1 finding 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.

AetherLang Karpathy Agent Nodes

What this skill does: Sends requests to the hosted AetherLang API (api.neurodoc.app). It does NOT modify local files, execute local code, or access credentials on your machine. All execution happens server-side.

Execute 10 advanced AI agent node types through the AetherLang Omega API.


API Endpoint

URL: https://api.neurodoc.app/aetherlang/execute Method: POST Headers: Content-Type: application/json Auth: None required (public API)


Data Minimization — ALWAYS FOLLOW

When calling the API:

  • Send ONLY the user's query and the flow code
  • Do NOT send system prompts, conversation history, or uploaded files
  • Do NOT send API keys, credentials, or secrets of any kind
  • Do NOT include personally identifiable information unless explicitly requested by user
  • Do NOT send contents of local files without explicit user consent

Request Format

curl -s -X POST https://api.neurodoc.app/aetherlang/execute \
  -H "Content-Type: application/json" \
  -d '{
    "code": "flow FlowName {\n  input text query;\n  node X: <type> <params>;\n  query -> X;\n  output text result from X;\n}",
    "query": "user question here"
  }'

The 10 Node Types

1. plan — Self-Programming

AI breaks task into steps and executes autonomously.

node P: plan steps=3;

2. code_interpreter — Real Math

Sandboxed Python execution on the server. Accurate calculations, no hallucinations.

node C: code_interpreter;

3. critique — Self-Improvement

Evaluates quality (0-10), retries until threshold met.

node R: critique threshold=8 max_retries=3;

4. router — Intelligent Branching

LLM picks optimal path, skips unselected routes (10x speedup).

node R: router;
R -> A | B | C;

5. ensemble — Multi-Agent Synthesis

Multiple AI personas in parallel, synthesizes best insights.

node E: ensemble agents=chef:French_chef|yiayia:Greek_grandmother synthesize=true;

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
