Crate rtk_mcp_cc 

Shared logic for the rtk-mcp-cc plugin.

Everything here is pure and unit-tested: settings resolution, the argument vectors handed to rtk, and the hook’s pass-through decision. The binaries in src/bin/ only move bytes and spawn processes.

The guiding constraint is that this plugin owns no rewriting logic. rtk already speaks Claude Code’s PreToolUse schema natively via rtk hook claude — it reads the event on stdin and writes hookSpecificOutput.updatedInput on stdout. Re-implementing that here would duplicate knowledge rtk owns and drift the moment rtk changes. So the hook delegates, and this crate’s job is only to delegate safely.
