What is quantcli CLAUDE.md?

A project instruction file for QuantCLI, a command-line tool for selecting stocks using several measurable factors. It explains the project's structure, design rules, data handling, and multi-stage filtering process.

Use it when working on QuantCLI's data sources, formula parser, core engine, JSON output, or stock-selection pipeline.

It gives a coding agent the repository context and rules it needs to make consistent changes. This reduces guesswork about where code belongs and how the tool should behave.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02660	$0.02660
Opus 5.5	$0.01064	$0.01064
Sonnet 5.5	$0.00532	$0.00532
Haiku 4.5	$0.00266	$0.00266

Security

Grade A, and why

quantcli 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 2mo 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.

Project Overview

QuantCLI - A multi-factor stock selection CLI tool for quantitative research.

AI Agent Friendly: Designed for AI Agent integration with:

JSON output mode (--json) for structured data
Claude Code Skill support (/skill multi-factor-strategy)
Idempotent APIs for safe retries
Alpha101 factor library examples

Target Users: Individual quant researchers, students, part-time investors, AI Agents

Core Design Principles

Let it Crash: Fail fast, fail loud. No tolerance for silent errors. Force correctness.
YAGNI: You Aren't Gonna Need It. Resist over-engineering. Solve today's problems.
80/20 Rule: 80% of use cases covered by 20% of features.
DataFrame First: All APIs return/accept pd.DataFrame, not List[Dict].

Multi-Stage Filter Pipeline Flow

Stage 1: fundamental_data → fundamental_conditions → candidates
Stage 2: price_data → daily_conditions → filtered candidates
Stage 3: factors → weight fusion + conditions + bonuses → ranked results

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.
