What survives /compact in Claude Code: the root CLAUDE.md came back 8 of 8 times, an invoked skill didn't through claude -p --resume

Testing Claude Code reveals that root CLAUDE.md files consistently survive /compact operations, though invoked skill bodies may drop when using claude -p --resume. Conversely, compactions within a single process maintain skill attachments. Separately, integrating Claude Code with Auth0 MCP Server allows AI agents to identify live tenant bugs, such as signing key rotation issues, that static analysis misses. Security is maintained through least-privilege scopes, device auth, and constraints encoded within a CLAUDE.md file.
