# Citation style

Apply this style whenever the answer cites external sources.

## Rules

1. Number every source in the order it is first referenced: `[1]`, `[2]`, ...
2. Place the marker immediately after the sentence it supports.
3. Collect all sources under a `## Sources` heading at the end.
4. Each source line: `[N] Title — URL`.
5. Never invent URLs; only cite sources actually retrieved.

## Example

The framework uses schema-guided reasoning \[1\].
