Recipes

For coding runtimes, start with Claude Code writes, Codex reviews: in-process verification, offline mocks and native session continuation. For repository jobs and MCP code-support tools, follow the LazyTools code bridge and code-support docs.

Each recipe is a runnable example from the examples/ directory in the repository, embedded verbatim and walked through. Run any of them directly with python examples/<file>.py once you have the relevant provider key in your environment.

The recipes are roughly ordered by the progressive complexity ladder: single agent → tools → composition → planning → production.

Single agent + tools

• React agent — examples/langgraph/01_react_agent_weather.py
• Researcher (single agent) — examples/crewai/01_research_crew_single_agent.py

Sequential composition

• Researcher → reporter — examples/crewai/02_research_and_report.py

Hierarchical / supervisor

• Supervisor pattern — examples/langgraph/02_supervisor_research_math.py

Planning patterns

• Plan tool — examples/patterns/plan_tool.py
• Agent builds a plan — examples/patterns/agent_builds_plan.py
• Blackboard planner — examples/patterns/blackboard_planner.py
• Durable blackboard — examples/patterns/durable_blackboard.py
• Dynamic re-planning — examples/patterns/dynamic_planner.py

Composition shapes

• Nested pipelines (horizontal) — Plan-of-Plans, parallel bands of sub-pipelines, and LLM-decided dispatch over sub-pipelines. Companion to the vertical chain / Plan recipes above.

Observability

• Live visualization — examples/viz_demo.py
• Visualization mock — examples/viz_mock_demo.py
