# API Reference

## lambdagent

### Core
- `Term` — Base class for all Lambda terms
- `Context` — Evaluation environment (Γ)
- `TraceEntry` — One β-reduction record

### Primitives
- `Lam(name, prompt, model, temperature, max_tokens)` — Lambda abstraction
- `Compose(*stages)` — Function composition (also via `>>`)
- `If(cond, then_, else_)` — Church conditional
- `Loop(body, condition, max_steps)` — Y combinator
- `Pair(first, second)` — Church pair
- `Fst()` / `Snd()` — Projections
- `Tool(name, fn)` — External oracle

### Extensions
- `Par(*agents)` — Parallel execution (also via `|`)
- `Route(classifier, routes, default)` — CASE dispatch
- `Guard(agent, validator, retry, on_fail)` — Dependent type
- `Memory(agent, store)` — Environment extension

### Compiler
- `from_config(path, **overrides)` — YAML → Term
- `lint_config(path_or_dict)` — Static analysis
- `to_lambda_expr(path_or_dict)` — Export Lambda notation
- `describe_config(path_or_dict)` — Human-readable description

### Runtime
- `Runtime.execute(config_path, input, **overrides)` — One-shot execution
- `Executor` — β-reduction engine
- `ReActEngine` — 7-phase ReAct loop
- `LLMAdapter` — Multi-provider LLM (Anthropic/OpenAI/DashScope)
