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

short-interest 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 8d 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.

Short Interest Analysis

⚠️ Data Verification — Do This Before Any Analysis

Before running any analysis, always retrieve the latest market data for the ticker:

  1. Fetch current price — use web search or ask the user for the live price, 52-week range, and market cap. Never assume a price from training data.
  2. Confirm key figures — recent earnings, revenue, key ratios (P/E, P/S, etc.) as applicable to this skill.
  3. State your data source — note where the numbers came from (e.g., "Google Finance, June 19 2026") at the top of the output.
  4. Flag stale data explicitly — if live data is unavailable, display this warning before proceeding:

⚠️ Live data unavailable. The following analysis uses training-data estimates which may be significantly out of date. Verify all prices and metrics before making any decisions.

Never silently substitute training-data estimates for current prices. When in doubt, ask the user to paste the latest quote.


Comprehensive analysis of short selling activity, squeeze potential, cost-of-borrow dynamics, and bearish positioning signals for US-listed stocks. Combines FINRA short interest data, options market signals, and technical context to assess directional risk.

Analysis Framework

1. Short Interest Overview

Measure the current level and trend of bearish positioning:

Core Short Interest Metrics

  • Short interest (shares): Total number of shares sold short and not yet covered or closed
  • Short float %: Short shares / Total float (shares available for public trading)
  • Short interest as % of shares outstanding: Short shares / Total shares outstanding (includes locked-up insider shares)
  • Float % is the more actionable metric — tighter supply amplifies squeeze dynamics

Short Float % Thresholds

Short Float %     Interpretation
<2%               Negligible — minimal bearish conviction
2-5%              Low — modest skepticism or hedging
5-10%             Moderate — meaningful bearish positioning
10-20%            Elevated — significant short thesis in market
20-30%            High — heavy bearish conviction, squeeze potential
>30%              Extreme — high risk environment (squeeze OR fundamental collapse)

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.
