Add subagent Cortex Code integrations

[sfc-gh-tjia]

Summary

• Add the full subagent-cortex-code/ repository as a source folder in snowflake-ai-kit
• Link the new folder from the root README as additional Codex, Cursor, and terminal integrations
• Keep the existing plugins/cortex-code/ Claude Code plugin unchanged

Notes

• This imports only tracked files from Snowflake-Labs/subagent-cortex-code
• No nested .git, generated bytecode, large files, or local personal artifacts are included
• Root README wording intentionally avoids positioning this as a replacement for the existing Claude Code plugin

Validation

• bash tests/run-tests.sh → 23 passed, 0 failed, 0 warnings, 1 skipped
• Sensitive-file scan found no real secrets; hits were test fixtures or generic sanitizer examples only

Thanks for bringing the Codex, Cursor, and CLI integrations into the kit — these are valuable additions. However, since snowflake-ai-kit is the single canonical repo (not a mirror of subagent-cortex-code), we need to restructure to avoid duplication with what already ships here.

Requested changes

1. Remove integrations/claude-code/ — this duplicates plugins/cortex-code/ which is already maintained in this repo.

2. Remove skills/cortex-code/ — same scripts already exist in plugins/cortex-code/scripts/.

3. Remove shared/scripts/ — third copy of the same code (execute_cortex.py, route_request.py, etc.).

4. Drop internal design docs — docs/plans/ and docs/specs/ are internal design artifacts, not user-facing. Keep docs/references/ (CLI reference, troubleshooting, routing examples).

5. Rename subagent-cortex-code/ to integrations/ — this is no longer a separate repo; the directory name should reflect its role within ai-kit.

Target structure

snowflake-ai-kit/
├── plugins/cortex-code/          # Claude Code plugin (existing, unchanged)
├── integrations/
│   ├── codex/                    # OpenAI Codex (new)
│   ├── cursor/                   # Cursor IDE (new)
│   └── cli-tool/                 # Standalone Python CLI (new)
├── shared/security/              # Shared security modules (single copy)
└── tests/                        # Unified test suite

This keeps the net-new value (Codex, Cursor, CLI tool, security tests) while eliminating the 3x duplication of core scripts. Happy to help with the restructure if useful.
