Examples

All examples run without an API key using MNESIS_MOCK_LLM=1:

MNESIS_MOCK_LLM=1 uv run python examples/01_basic_session.py
MNESIS_MOCK_LLM=1 uv run python examples/05_parallel_processing.py

To use a real LLM, set the appropriate API key and omit the flag:

ANTHROPIC_API_KEY=sk-ant-... uv run python examples/01_basic_session.py

01 — Basic Session

examples/01_basic_session.py

Demonstrates the core send() loop:

• Creating a session with MnesisSession.create()
• Sending messages and reading TurnResult
• Monitoring compaction_triggered
• Inspecting cumulative token usage
• Async context manager lifecycle

---

02 — Long-Running Agent

examples/02_long_running_agent.py

• Subscribing to EventBus events
• Streaming callbacks via on_part
• Manually triggering session.compact()
• Inspecting compaction results

---

03 — Tool Use

examples/03_tool_use.py

• Passing tool definitions to send()
• Handling ToolPart streaming states (pending → running → completed)
• Inspecting tombstoned tool outputs after pruning

---

04 — Large Files

examples/04_large_files.py

• Using LargeFileHandler to ingest files
• FileRefPart and content-addressed storage
• Cache hits on repeated file access
• Exploration summaries (AST outline, schema keys, etc.)

---

05 — Parallel Processing

examples/05_parallel_processing.py

• LLMMap with a Pydantic output schema
• AgenticMap with independent sub-agent sessions
• Concurrency control and per-item retry

---

06 — BYO-LLM

examples/06_byo_llm.py

• Using session.record() to inject turns from your own SDK
• Building the LLM message list from session.messages()
• Passing explicit TokenUsage for accurate compaction budgeting

This example includes a canned-response stub so it runs without any API key. See BYO-LLM for a full explanation.
