 ## Domain 2: The Meta-Tooling

 - **Purpose**: The external AI agents (you, reading this) used to write the code for the Application.
-- **Safety Model**: Driven by the external agent's own framework (e.g., Gemini CLI's auto-approval policies or Claude Code's permissions). These agents have their own sandboxing and do *not* use the Application's GUI for approval unless explicitly hooked.

 - **Tooling Control**: These external agents use `mcp_client.py` natively to investigate and modify the `manual_slop` codebase (e.g., using `set_file_slice` to fix a bug).
 
+### The Cross-Tool Abstractions
+
+The Meta-Tooling domain is itself split by which external agent consumes it:
+
+- **Gemini CLI** (the primary toolchain as of 2026-06-02): Uses the **conductor extension** which reads `./conductor/` for task tracking, workflow, and product context. Skills are activated via `activate_skill`.
+- **OpenCode** (secondary): Uses **superpowers** or the conductor convention directly. Skills live in `.agents/skills/` and are activated by name.
+- **Claude Code** (legacy, no longer primary): Uses the original `.claude/commands/*.md` slash command inventory. The `claude_mma_exec.py` script may be vestigial.
+
+**The conductor system in `./conductor/` is the cross-tool abstraction.** Both Gemini CLI and OpenCode consume `conductor/workflow.md`, `conductor/product.md`, `conductor/tech-stack.md`, and `conductor/tracks.md`. Track implementation follows the TDD protocol documented in `conductor/workflow.md` regardless of which external agent is doing the work.

 ## The Inter-Domain Bridges: `cli_tool_bridge.py` & `claude_tool_bridge.py`
 To achieve true Human-In-The-Loop (HITL) safety while developing the app *with* external AI tools, the project provides "Bridge" scripts.
 - **How they work**: These scripts (`cli_tool_bridge.py` for Gemini CLI, `claude_tool_bridge.py` for Claude) intercept the tool execution requests from the external AI.

 - **The Result**: The `manual_slop` GUI intercepts this network request and pops open a modal asking the human developer if they approve the action requested by the *external* Meta-Tooling agent.
 - **Environment Context**: These bridges check the `GEMINI_CLI_HOOK_CONTEXT` or `CLAUDE_CLI_HOOK_CONTEXT` environment variables. If the variable is set to `mma_headless` (which happens during `mma_exec.py` sub-agent execution), the bridge automatically **allows** the execution to prevent sub-agents from blocking the main thread waiting for human GUI clicks.
 
+### Bridge Status (as of 2026-06-02)
+
+- `cli_tool_bridge.py` — **Active.** Primary toolchain is Gemini CLI.
+- `claude_tool_bridge.py` — **Vestigial.** The project no longer uses Claude Code as a primary toolchain. The file is kept for backward compatibility with any external tooling that may still reference it. New meta-tooling work should target Gemini CLI (or OpenCode via the conductor convention), not Claude.
+- An `opencode_bridge.py` is **not** present. OpenCode uses its own hook system (`.opencode/hooks.json`) and does not require an explicit bridge — the conductor convention is the bridge.
+
 ## The Overlap & Entropy Vector: `mcp_client.py`
 `mcp_client.py` is the shared bridge. 
 - It was originally written to give the Application's internal AI some read-only file context tools.
