alpha-zoo

alpha-zoo is a skill for Claude Code, Codex from skloxo/TideTrading. It costs 79 tokens per session (1,036 once invoked), scanned A, a copy of alpha-zoo, MIT.

A library and testing tool for prebuilt investment factors, which are formulas used to rank or compare assets. It covers named collections such as Kakushadze 101, GTJA 191, Qlib 158, and Fama-French or Carhart factors.

In plain words
What is it for?
Browse factors by collection, theme, or market; inspect one factor's details; test one factor or an entire collection on a market universe and time period; or evaluate your own factor and return CSV files.
Why use it?
It removes the need to search through factor libraries manually or build separate tests for each factor. It can compare factors using IC and IR, common measures of how useful a factor may be for predicting returns.

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

alpha-zoo 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 10d 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.

Alpha Zoo

Purpose

When the user asks about prebuilt cross-sectional alphas — Kakushadze 101, GTJA 191, Qlib 158, Fama-French / Carhart — or wants to bench a whole zoo on an investable universe (CSI 300, S&P 500, BTC-USDT, ...), this skill orients you. The zoo is the curated library; the bench is the evaluator.

Tools Available

Tool When to use
alpha_zoo Browse the library. action=list_alphas to enumerate (filterable by zoo / theme / universe), action=get_alpha for one alpha's metadata, action=health for registry load status.
alpha_bench Run IC / IR on one alpha or a whole zoo over a universe + period. Emits an HTML report.
factor_analysis Ad-hoc factor evaluation from a user-supplied factor CSV + return CSV. Use this when the user has their own factor (not in the zoo).

Decision Tree

  • "list all momentum alphas" → alpha_zoo with action=list_alphas, theme=momentum.
  • "show me gtja191_alpha_001" → alpha_zoo with action=get_alpha, alpha_id=gtja191_alpha_001.
  • "bench all of GTJA 191 on CSI 300 from 2020 to 2024" → alpha_bench with zoo=gtja191, universe=csi300, period=2020-2024.
  • "is the registry healthy" → alpha_zoo with action=health — surfaces loaded, failed, and per-error reasons.
  • User uploads my_factor.csvfactor_analysis (zoo tools are for prebuilt alphas only).

Zoo Inventory

Zoo Description Approx. count
kakushadze101 Formulaic alphas from Kakushadze's 2015 paper. Mix of momentum, reversal, volume, and microstructure. ~101
gtja191 Guotai Junan 191 alphas — A-share focused cross-sectional factors. ~191
qlib158 Microsoft Qlib's 158 alpha factors — features tuned for ML pipelines. ~158
classical Fama-French 3/5-factor + Carhart momentum. <10

Counts are nominal; check alpha_zoo action=health for the live count currently loaded.

Constraints

  • No per-stock per-date factor values are surfaced to the agent. IC results are aggregate stats (mean / std / IR / positive-ratio); the HTML report shows top-N by IR plus formulas, never the underlying panel.
  • Lookahead is banned in the operator set. delta(df, d) requires d >= 1; the negative-shift Ref(df, -n) form does not exist. See docs/alpha-zoo/spec.md for the full operator catalogue.
  • Universe loaders may not be wired for every market yet. When alpha_bench returns universe loader for X not yet implemented, that's the W2 scaffold — the universe is recognised but the data pull lands in W4.
  • Do not expose absolute filesystem paths in agent output. The bench tool writes to ~/.vibe-trading/reports/ by default; refer to it by that shorthand, not by the resolved absolute path.
  • alpha_zoo is read-only. alpha_bench writes a single HTML file per run — no scratch state elsewhere.

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.
