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

canslim-screener 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 11d ago.

The scan reads SKILL.md. This mod also ships 16 executable files (scripts/calculators/earnings_calculator.py, scripts/calculators/growth_calculator.py, scripts/calculators/institutional_calculator.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

CANSLIM Stock Screener - Phase 3 (Full CANSLIM)

Overview

This skill screens US stocks using William O'Neil's proven CANSLIM methodology, a systematic approach for identifying growth stocks with strong fundamentals and price momentum. CANSLIM analyzes 7 key components: Current Earnings, Annual Growth, Newness/New Highs, Supply/Demand, Leadership/RS Rank, Institutional Sponsorship, and Market Direction.

Phase 3 implements all 7 of 7 components (C, A, N, S, L, I, M), representing 100% of the full methodology.

Two-Stage Approach:

  1. Stage 1 (FMP API + Finviz): Analyze stock universe with all 7 CANSLIM components
  2. Stage 2 (Reporting): Rank by composite score and generate actionable reports

Key Features:

  • Composite scoring (0-100 scale) with weighted components
  • Finviz fallback for institutional ownership data (automatic when FMP data incomplete)
  • Progressive filtering to optimize API usage
  • JSON + Markdown output formats
  • Interpretation bands: Exceptional+ (90+), Exceptional (80-89), Strong (70-79), Above Average (60-69)
  • Bear market protection (M component gating)

Phase 3 Component Weights (Original O'Neil weights):

  • C (Current Earnings): 15%
  • A (Annual Growth): 20%
  • N (Newness): 15%
  • S (Supply/Demand): 15%
  • L (Leadership/RS Rank): 20%
  • I (Institutional): 10%
  • M (Market Direction): 5%

Future Phases:

  • Phase 4: FINVIZ Elite integration → 10x faster execution

When to Use This Skill

Explicit Triggers:

  • "Find CANSLIM stocks"
  • "Screen for growth stocks using O'Neil's method"
  • "Which stocks have strong earnings and momentum?"
  • "Identify stocks near 52-week highs with accelerating earnings"
  • "Run a CANSLIM screener on [sector/universe]"

Implicit Triggers:

  • User wants to identify multi-bagger candidates
  • User is looking for growth stocks with proven fundamentals
  • User wants systematic stock selection based on historical winners
  • User needs a ranked list of stocks meeting O'Neil's criteria
