Custom Agent Builder API
Added build_custom_agent() for creating user-defined
graph/state-machine agents from custom node functions, static edges, and
conditional edges.
Exported State-Graph Primitives
Exported StateGraph(), make_node(),
make_edge(), make_command(), and
interrupt() to support custom workflow
construction.
LangGraph-Style Mermaid Export
Added compile_graph() and as_mermaid() for
Mermaid visualization, including optional subgraph grouping and graph
direction control.
PNG Graph Export Utility
Added save_mermaid_png() to render Mermaid graph text (or
compiled graph objects) into PNG files via Mermaid CLI
(mmdc).
Reusable Code Agent with Builder Pattern
The build_code_agent() function now supports a builder
pattern. If user_input is omitted, the function returns a
reusable agent (closure) that can handle multiple queries interactively.
This allows for flexible integration in iterative coding workflows,
similar to the existing build_researcher_agent().
Reusable Interpreter Agent
The build_interpreter_agent() function now also supports a
builder pattern. When code_output is omitted, it returns a
reusable interpreter function that can process multiple outputs (tables,
model results, charts, etc.) on demand. This provides a consistent
interface for explaining analysis results dynamically.
build_code_agent() and
build_interpreter_agent() in two ways:
user_input, code_output) for immediate
interpretation or code generation.build_code_agent() and
build_interpreter_agent() that use the one-shot pattern
will continue to work without modification.
