Each role in model_registry.json can now carry two optional keys:
system_append — injected into the system prompt at position 7 (after
memory, closest to the turn) for the active chat_role
tools — explicit tool allow-list; intersected with the user's
access-level filter so it can only restrict, never elevate
No changes needed for existing users — missing keys fall back to current
behavior. Add keys to a role to give it a specialty focus:
"coder": {
"primary": "claude_cli",
"system_append": "You are in code-specialist mode...",
"tools": ["web_search", "file_read", "shell_exec", "scratch_write"]
}
Changes:
- model_registry.py: get_role_config() returns system_append + tools
- context_loader.py: role_append param appended as "--- Role Context ---"
- tools/__init__.py: get_tools_for_role/get_openai_tools_for_role accept
optional tool_list and intersect with access-level filter
- orchestrator_engine.py: tool_list threaded through run/resume/checkpoint
- openai_orchestrator.py: tool_list threaded through run/resume/checkpoint;
_build_client now calls get_openai_tools_for_role instead of returning
unfiltered OPENAI_TOOL_SCHEMAS
- routers/orchestrator.py: pulls role_cfg for chat_role, passes both
role_append and tool_list to context loader and engine
