10-K Report Digest - InvestSkill

⚠️ Data Verification — Do This Before Any Analysis

Before running the digest, confirm the filing details:

Identify the filing — confirm ticker, fiscal year-end, and exact 10-K filing date from SEC EDGAR.
State your source — note where the document came from (e.g., “SEC EDGAR, FY2024 10-K filed 2025-02-05”) at the top of the output.
Flag incomplete data — if only partial sections are available, list what is missing before proceeding.

⚠️ Source unavailable. If the full 10-K cannot be retrieved, display this warning and proceed only with the sections provided.

Produce a clean, structured markdown document that distills a company’s 10-K annual report into an abstract, per-section summaries, a digest of key metrics, and full source references. Designed for quick comprehension — not trading signals. Output language is selectable: English or Traditional Chinese (繁體中文).

How to Use

Provide input in any of these ways:

By ticker: AAPL — fetches the latest 10-K from SEC EDGAR
With fiscal year: MSFT FY2024
Pasted text: paste 10-K sections directly into the prompt
Language flag: add --lang zh-TW to output in Traditional Chinese (繁體中文)
File output: add --output <filename>.md to save the digest as a markdown file
