Persist agent state across runs, shape what the LLM sees per turn, and cap history to fit a context window. Covers `KnowledgeStore` (memory / sqlite / disk / redis), `KnowledgeConfig` (`store=`, `compact=`, `aggregate=`, `bootstrap=`), aggregation strategies (`WorkingMemoryAggregate`, `ConversationSummaryAggregate`), assembly policies (`WorkingMemoryPolicy`, `EpisodicMemoryPolicy`, `ConversationPolicy`, `SlidingWindowPolicy`, `TokenBudgetPolicy`, `AlertPolicy`), and compaction (`TailWindowCompact`, `SummarizeCompact`). Use when the user wants the agent to remember between conversations, manage long histories, or control prompt assembly.
Monitor an AG2 beta agent's stream — log events, detect repeated tool calls, track token spend, build trigger-driven observers, route observer alerts to the model, and halt on FATAL conditions. Covers `@observer(...)` (stateless), `BaseObserver` (stateful), built-ins (`TokenMonitor`, `LoopDetector`), `Watch` primitives (`EventWatch`, `CadenceWatch`, `DelayWatch`, `IntervalWatch`, `CronWatch`, `AllOf`, `AnyOf`, `Sequence`), `ObserverAlert` (`Severity.INFO/WARNING/CRITICAL/FATAL`), `AlertPolicy`, and `HaltEvent`. Use when the user wants observability, runtime safety guards, alerts, or batch/time-based reactive logic.
Add a custom Python tool to an AG2 beta `Agent` using the `@tool` decorator. Use when the user wants to give an Agent a new capability backed by Python code (API calls, DB queries, computations, file ops). Covers sync and async tools, parameter typing, Pydantic schema customisation, returning typed `Input` / `ToolResult` (text / data / images / binary), `final=True` early-exit, and dependency injection via `Context` / `Inject` / `Variable` / `Depends`.

| name | calculator |
| description | Evaluate arithmetic expressions using a sandboxed Python script. |
| version | 0.1.0 |
Use this skill whenever the user asks for an arithmetic calculation (addition, subtraction, multiplication, division, exponentiation, modulo, or any expression that combines them).
Call the run_skill_script tool with:
name: "calculator"script: "calc.py"args: a single-element list containing the expression as a string,
e.g. ["(2 + 3) * 4"].The script prints the result of the expression. Report the printed value back to the user verbatim.
args=["17 * 23"]args=["(100 - 7) / 3"]
