Does swiftlang/swift-format have agent instructions?

An AGENTS.md (or CLAUDE.md) at the root tells AI coding agents how to build, test and work in the repo. A few agents also read a file of their own.

AGENTS.md / CLAUDE.md
None at the root (no AGENTS.md, CLAUDE.md or AGENT.md)
Agent-specific files
None: no GEMINI.md, .cursor/rules, .openhands/setup.sh or .aider.conf.yml
