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

stock-deep-dive 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/dossier.mjs), 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.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stock Deep Dive — everything on one ticker

This is the single-stock counterpart to stock-recap (which scans the whole market). Here the user hands you one ticker and wants the complete read fast. It exists so Michael can ask you "do you like PLTR down here?" instead of pulling up six tabs of technicals, options, ownership, and news himself.

It pulls four legs for the ticker and you add a fifth (news):

  1. Technicals — TD Pro /api/agent/ticker/:SYM: RSI, ADX, stoch, MACD, ATR, the full EMA/SMA ladder (8/21/55/89/50/200), trend status, EMA stack, buy-zone, squeeze ratio, Williams %R, CCI, Bollinger %B, pivots (S2→R2), fib retrace (.382/.500/.618), Keltner channel, 90-day range, and bounce state.
  2. Options positioning — same endpoint: max pain, call wall (resistance), put wall (support), expected move to next expiry, IV skew + dealer sentiment, put/call OI ratio, and the biggest open-interest strikes (call vs put OI).
  3. Options flow — TD Pro /api/agent/unusual-activity?ticker=SYM over the last week: net bullish vs bearish premium, call vs put premium, the largest trades, institutional-alpha tier, and repeat-strike conviction.
  4. Institutional ownership — TickerTrace /ticker/:SYM: which funds/ETFs hold it and at what weight, plus recent 13F changes (adds/trims, including option overlays). Read the provider + type — a YieldMax/Roundhill option overlay is income mechanics, not a directional conviction bet.
  5. News / catalystsnot in the script (no TD Pro news endpoint). After the pull, you WebSearch for recent headlines, earnings dates, guidance, analyst moves — whatever explains where price is — and fold it into the verdict.

It also renders a 90-day candlestick chart (reusing the stock-recap skill's Python venv + render_chart.py — no second install).

How to run it

  1. Run the dossier script with the ticker(s). Works from any directory — the absolute path resolves the symlink back into the mphinance repo, so the API key and the sibling stock-recap chart venv are found automatically:

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
