In plain words
What is it for?
Use it to plan a multi-article company study, examine how the business makes money, assess its competitive position and management, review its finances, and set valuation limits and warning signs.
Why use it?
Long company research can become persuasive without being well checked. This framework emphasizes revision and fact-checking so the analysis follows a consistent decision process.

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

deep-company-series 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 13d 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.

Deep-Company Series: An 8-Part Deep Dive on One Company

Write an 8-part deep-dive series (~120k words total) on a single company, from cognitive reset to a decision framework. The core IP is not "writing well" but "revising strictly" — most finance long-form violates this skill's fact-check standard.

1. When to Use

The user wants "textbook-level" deep research on a company, published as a series of long-form articles. Distinct from a single research report:

  • 8 parts, ~120k words, full loop from cognitive reset to a decision framework
  • Each part stands alone (shareable singly) but shares one valuation / management / price framework
  • Written for readers willing to spend 90 minutes understanding one company

Not for: a single research report, earnings note, sector study — use other skills (fundamentals / earnings / sector).

2. Series Template (8 Parts)

# Title template Core question Words
01 You think you understand X — you don't Cognitive reset: break 3 common illusions 4,000-5,000
02 X's moat — {one-line business essence} Is the moat deep; will it be there in 5/10 years 6,000-8,000
03 X's biggest profit engine — {most profitable business} What is the core business; why it persists 6,000-8,000
04 The other company hidden on X's balance sheet — {hidden asset} Investment portfolio / subsidiary / hidden value 8,000-10,000
05 In the AI (or current narrative) era, is X a winner or loser Era variable: decompose the impact by business 8,000-10,000
06 Reading X's financials the Buffett way Financial depth: gross margin / FCF / ROE / SBC 8,000-10,000
07 {management quote} — is X's management worth entrusting Capital-allocation discipline + integrity test + succession 8,000-10,000
08 At what price to buy, what signal to sell (finale) DCF 3-scenario + red lines + position framework 10,000-12,000

Plus 00-series-overview.md as an index (unpublished).

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.
