One Config, Six AI Harnesses: Universal Tool Parity

TormentNexus maintains byte-for-byte tool signature parity across all major AI coding harnesses. 27 golden fixtures, 6 L2 platforms:

Platform	Tool Parity	Fixture Count
Claude Code	Ready for L3 lock	3
GitHub Copilot CLI	Ready for L3 lock	4
Codex CLI	Ready for L3 lock	3
Cursor	Ready for L3 lock	3
Gemini CLI	Ready for L3 lock	2
Kiro	Ready for L3 lock	2

Tool equivalence examples:

• shell_execution: bash() (Copilot/Codex/Gemini), Bash() (Claude), Shell() (Cursor)
• file_read: view() (Copilot), read (Codex), Read() (Claude/Cursor), file-read (Gemini)
• file_write: edit()/create() (Copilot), write (Codex), Edit()/Write() (Claude/Cursor)

One config, identical tool signatures across 6+ harnesses. No vendor lock-in.
