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

theme-detector 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 1mo ago.

The scan reads SKILL.md. This mod also ships 30 executable files (scripts/calculators/__init__.py, scripts/calculators/heat_calculator.py, scripts/calculators/industry_ranker.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.

Theme Detector

Overview

This skill detects and ranks trending market themes by analyzing cross-sector momentum, volume, and breadth signals. It identifies both bullish (upward momentum) and bearish (downward pressure) themes, assesses lifecycle maturity (Emerging/Accelerating/Trending/Mature/Exhausting), and provides a confidence score combining quantitative data with narrative analysis.

3-Dimensional Scoring Model:

  1. Theme Heat (0-100): Direction-neutral strength of the theme (momentum, volume, uptrend ratio, breadth)
  2. Lifecycle Maturity: Stage classification (Emerging / Accelerating / Trending / Mature / Exhausting) based on duration, extremity clustering, valuation, and ETF proliferation
  3. Confidence (Low / Medium / High): Reliability of the detection, combining quantitative breadth with narrative confirmation. Script output is capped at Medium; Claude's WebSearch narrative confirmation step can elevate to High.

Key Features:

  • Cross-sector theme detection using FINVIZ industry data
  • Direction-aware scoring (bullish and bearish themes)
  • Lifecycle maturity assessment to identify crowded vs. emerging trades
  • ETF proliferation scoring (more ETFs = more mature/crowded theme)
  • Integration with uptrend-dashboard for 3-point evaluation
  • Dual-mode operation: FINVIZ Elite (fast) or public scraping (slower, limited)
  • WebSearch-based narrative confirmation for top themes

When to Use This Skill

Explicit Triggers:

  • "What market themes are trending right now?"
  • "Which sectors are hot/cold?"
  • "Detect current market themes"
  • "What are the strongest bullish/bearish narratives?"
  • "Is AI/clean energy/defense still a strong theme?"
  • "Where is sector rotation heading?"
  • "Show me thematic investing opportunities"

Implicit Triggers:

  • User wants to understand broad market narrative shifts
  • User is looking for thematic ETF or sector allocation ideas
  • User asks about crowded trades or late-cycle themes
  • User wants to know which themes are emerging vs. exhausted
