The swift format command uses .swift-format but the downloaded file is .swift-format. However, the documentation in AGENTS.md and AGENCY.md references the full URL. For consistency and to avoid network dependencies during formatting, the workflow should use the local file, but the documentation should be updated to match this local usage pattern.

[Copilot]

[nitpick] The formatting command references a remote URL which creates a network dependency for local development. Consider documenting a two-step process: first download the configuration file locally, then run swift format with the local file, similar to how the CI workflow operates.

Suggested change

	- Format any modified Swift files with `swift format --configuration https://raw.githubusercontent.com/wrkstrm/configs/main/linting/.swift-format -i -r -p`. This is the only Swift formatting step to run.
	- Format any modified Swift files using a two-step process:
	1. Download the Swift format configuration file locally:
	`curl -o .swift-format https://raw.githubusercontent.com/wrkstrm/configs/main/linting/.swift-format`
	2. Run the formatter with the local configuration file:
	`swift format --configuration .swift-format -i -r -p`
	This is the only Swift formatting step to run.
