deep-company-seriesPlans and drafts an eight-part, roughly 120k-word investigative series on one company, built around a strict fact-check pass rather than fast drafting.
Lays out a fixed eight-part structure for a single company, moving from a cognitive-reset opener through the moat, the main profit engine, hidden balance-sheet assets, an era variable such as AI, Buffett-style financial reading, a management-integrity test, and a closing valuation piece with buy and sell signals. Each part can be read on its own but all eight share one valuation, management and pricing framework, so judgments stay consistent across the series.
States plainly that the hard part is not prose but revision: articles get checked against a list of common finance-writing failures, among them probability-weighted guesses dressed up as precision, mismatched third-party usage figures, straight-line extrapolation, absolute claims, and numbers that contradict each other across the eight parts. The voice is direct and data-first, shows the counterargument to every core judgment, and is written so the opening words work on a mobile preview. An unpublished `00-series-overview.md` file indexes the parts.
This skill is explicitly not for a single research note or earnings update; those belong to other, narrower skills. It fits a reader willing to spend roughly 90 minutes on one company, not a quick take.
7 steps, taken from the step headings in SKILL.md.

Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Eight-Part Company Deep Dive loads about 2.4k tokens when it runs. Until then it costs about 201 tokens; SKILL.md has 1,059 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/deep-company-series/SKILL.md (or your agent's skills folder).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.
The user wants "textbook-level" deep research on a company, published as a series of long-form articles. Distinct from a single research report:
Not for: a single research report, earnings note, sector study — use other skills (fundamentals / earnings / sector).
| # | 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).

| severely mismatched / severely undervalued | Strong subjective | give the specific discount % |
| perfect / flawless | One-sided | add the counter-observation |
30% × A + 50% × B + 20% × C = expected +X% is almost always garbage — the probabilities are pure subjective, giving readers false precision. List scenarios + triggers + direction only; do not compute a weighted expectation.2025 +33% × 5y CAGR → 2030 X is financial illiteracy. Use scenario assumptions + high/low ranges; never a promise.□ 1. Cross-article number consistency: market cap, Non-IFRS net income, key holding % aligned across the series
□ 2. Caliber labeling: Non-IFRS / GAAP / Non-IFRS-SBC / FCF — which is used, clear throughout
□ 3. Double-counting scan: consolidated subs are NOT in the "investment portfolio"; SOTP doesn't count them twice
□ 4. Peer-comparison fairness: don't compare "core-business PE (cash + portfolio stripped)" with "peer PE (not stripped)"
□ 5. Probability-weighted expectations deleted (see above)
□ 6. Absolute language softened: grep "obviously|inevitably|severely|textbook|perfect"
□ 7. Third-party data sourced: every non-filing data point followed by "(source: X)"get_financial_statements — last 5 years of annuals, latest quarterlyget_research_reports / web_search — at least 3 independent sell-side reports (find consensus + dissent)run_swarm (e.g. equity_research_team or value_investing_committee) to generate an internal research draftwrite_file to reports/{company}/《Understanding {company}》/0X-XX.mdThis is the key differentiator. Use tools to scan:
read_file each part + report_audit (command=extract) to pull numbers (market cap, net income, holding %, PE) from eachfinancial_rigor (command=cross_validate) to cross-validate the same metric's values across articles; flag >1% deviation as a caliber mismatchread_file checks: is each term (FBS, SBC, Non-IFRS) defined at first use; do "see part 06" references actually resolve; do recaps match body numbersreport_audit (command=verdict) as a gate on each part: extract numbers → verify → PASS/FAILIf the user says "X is wrong", use get_financial_statements / web_search to cross-check the original; present "user's number vs what I found vs what I used".
| Grade | Type | Handle |
|---|---|---|
| 🔥 Hard error | wrong number / attribution / caliber | Must fix |
| ⚠️ Subjective | strong subjective word / hype metaphor | Soften or cut |
| 🔬 Granularity | source label, caliber refinement | Balance against readability |
| ❓ Unreliable | large third-party discrepancies | Deleting is safer than editing |
Before fixing one spot, think "where else is this number/concept referenced":
One-liner: writing an "Understanding X" series is about revising strictly, not writing well — most finance long-form dies from pseudo-precise numbers, subjective weighted expectations, and absolute language. This skill exists to flag all those traps before writing and sweep them clean after (report_audit + financial_rigor.cross_validate).

Each part can be read on its own but all eight share one valuation, management and pricing framework, so judgments stay consistent across the series.
Eight-Part Company Deep Dive fits situations like: writing a publication-length, multi-part analysis of a single public company; producing a textbook-depth series meant to be shared article by article; fact-checking a finance long-form for pseudo-precision and inconsistent numbers; building a company write-up around one shared valuation and management framework.
Run `npx skills add HKUDS/Vibe-Trading --skill deep-company-series -a claude-code`. Or copy the skill folder (agent/src/skills/deep-company-series in HKUDS/Vibe-Trading) into .claude/skills/deep-company-series in your project. Claude Code loads it when a task matches its description.
