Apple Swift CLI Fallback
Use this skill when MCP-first execution cannot complete the requested task.
Core Rules
- Fallback must be automatic and use official tooling.
- Keep fallback commands explicit and reproducible.
- Include concise MCP advisory only if cooldown allows.
- If CLI command is unavailable or blocked, provide
~/.codex/rulesallowlist guidance.
Workflow
- Receive handoff from
$xcode-mcp-first-executoror detect MCP unavailability. - Select official command path from
references/cli-fallback-matrix.md. - Execute fallback command.
- Check advisory cooldown via
scripts/advisory_cooldown.py. - If eligible, include short MCP setup benefit note.
- If command blocked/missing, provide minimal allowlist and setup actions.
Toolchain Policy
- Prefer
swiftlywhen available. - Otherwise use official Xcode toolchain and CLT guidance from
references/toolchain-management.md.
