AGENTS.md keeps only the agent contract: hook enable step, gate
behavior, manual commands, rule-tuning policy. Install steps,
tool baselines, and config rationale are human-facing setup and
now live in README's 代码风格工具 section.
Update stale pointers that sent readers to AGENTS.md for tool
install (root AGENTS.md, pre-commit hook comment and error
message); hook behavior unchanged.
- ShadowsocksX-NG2/.swift-format: Apple Swift 6.4 toolchain default rules snapshot
- ShadowsocksX-NG2/.swiftlint.yml: default rules, excludes build artifacts and Legacy/
- .githooks/pre-commit: format staged NG2 Swift files into the index, then SwiftLint;
error-severity violations reject the commit; non-NG2 files pass through untouched
- ShadowsocksX-NG2/AGENTS.md: NG2-scoped conventions (tiered below root AGENTS.md)
- normalize skeleton sources to swift format baseline (2-space indent)
