+Port coordinator skill-aware routing parity from upstream dev (fe1e7e8, 8a62093)
+
+- Coordinator agent configurations now scan 5 skill search paths in precedence order:
+  1. `.squad/skills/` (team-earned, highest priority)
+  2. `.copilot/skills/` (CLI-resident)
+  3. `.github/skills/` (repository-standard)
+  4. `.claude/skills/` (Claude-app-resident)
+  5. `.agents/skills/` (legacy fallback, lowest priority)
+
+- Traversal safety rules:
+  - Single-level scan only (no recursive descent)
+  - Reject symlinks and Windows reparse points
+  - Ensure filesystem-neutral validation
+
+- Skill name deduplication rules:
+  - Case-insensitive comparison
+  - NFC Unicode normalization
+  - Trim zero-width characters
+  - Reject null bytes, control characters, path separators
+  - Reject Windows reserved names (CON, PRN, AUX, NUL, COM1-9, LPT1-9)
+
+- Applied uniformly across all three coordinator template surfaces:
+  - `.github/agents/squad.agent.md` (repository coordinator)
+  - `.squad/templates/squad.agent.md` (team template)
+  - `src/Squad.SDK.NET/Templates/squad.agent.md.template` (SDK-shipped template)

+Preserve top-level squad files during sharing import/export by adding explicit payload support for files like `team.md`, `decisions.md`, and `routing.md`, including empty-file round-trip behavior.
