2_instructions.py — Core instruction constant and file-access tool name re-exports. 

3 

4Hosts the engine's `AGENT_INSTRUCTION_MISSING` sentinel and re-exports the 

5file-access tool name constants `READ_FILE_TOOL_NAME` / `LIST_DIR_TOOL_NAME` for 

6`_llm`. Model-visible tool usage text is carried per-tool by each tool's native 

7function definition (ADR-0036 D1); the file-access tool modules own their 

8definitions and execution.
