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

insider-tracker 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 12d 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.

Insider Activity Tracker

Overview

Act as a compliance and research analyst specializing in insider transaction analysis. Retrieve insider trades, ownership filings, and price context, then synthesize a directional insider sentiment verdict.

Announce at start: "Analyzing insider activity for [TICKER]..."

Input

Parse $ARGUMENTS as a single stock ticker (e.g., AAPL, TSLA). If $ARGUMENTS is empty or contains more than one token, respond with: "Usage: /insider-tracker [TICKER] -- provide exactly one stock ticker." and STOP.

Normalize ticker to uppercase. Set ticker variable.

Data Collection

Wave 1 -- ALL calls in parallel

Tool Parameters Priority
edgar_insider_trades ticker=ticker, limit=20 REQUIRED
edgar_ownership_filings ticker=ticker REQUIRED
tradingview_quote tickers=[ticker] REQUIRED
finnhub_earnings_calendar from=today, to=today+30, symbol=ticker ENRICHMENT
alphavantage_earnings_history symbol=ticker, limit=4 ENRICHMENT

If a REQUIRED tool fails, report the failure and continue with available data. If an ENRICHMENT tool fails, silently omit that section.

Analysis

DO NOT reproduce raw tool output. Cross-reference and synthesize:

  1. Classify trades. Separate insider transactions into buys vs sells. Note transaction sizes (shares and dollar value where available).
  2. Net insider sentiment. Count net buy vs sell transactions and net shares over the period. Exclude 10b5-1 planned sales from the net sell count before scoring. State the ratio clearly (e.g., "12 buys vs 3 sells").
  3. Cluster detection. Flag when 3+ distinct insiders trade in the same direction within a 30-day window. This is a strong directional signal.
  4. Pre-earnings timing. If earnings are within 30 days AND insiders traded recently, flag as potential pre-earnings positioning. Note the gap in days.
  5. Activist watch. Check ownership filings for 13D or 13G filings. These indicate activist or large block positions (>5% ownership).
  6. Price cross-reference. Compare insider trade direction with recent price trend. Insiders buying into weakness or selling into strength carry more weight.

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.
