# Company Identifier

> Resolve a company name or ticker to a confirmed identity with CIK, exchange, and sector.

## What it does

Takes a company name ("Apple"), ticker ("AAPL"), or informal reference ("the iPhone company") and resolves it to a confirmed identity using SEC EDGAR search and web verification.

## Output

| Field           | Example    |
| --------------- | ---------- |
| Legal name      | Apple Inc. |
| Ticker          | AAPL       |
| CIK             | 0000320193 |
| Exchange        | NASDAQ     |
| Sector          | Technology |
| Fiscal year end | September  |

## How it works

1. Searches SEC EDGAR's full-text company search for the input
2. Cross-references with exchange listings to confirm the ticker
3. Presents the match to the user for confirmation before proceeding
4. Handles edge cases: multiple matches, delisted companies, ADRs, dual-listed stocks

## Edge cases

* **Ambiguous names** — "Amazon" could be Amazon.com Inc. or Amazon Group Ltd. The skill presents options and asks the user to confirm.
* **Name changes** — companies that have renamed (e.g., Facebook → Meta) are resolved via SEC EDGAR's historical records.
* **Non-US companies** — currently supports US-listed companies only (those with SEC filings).

<Note>
  This skill has no Python library component — it's pure conversation + web search. All other skills depend on the CIK it produces.
