Global Summary

Rig is a minimal TypeScript multi-agent harness that provides declarative agent construction with typed input/output schemas, prompt intents, and pluggable engine backends (Copilot, Anthropic, Gemini, Codex, Pi). The repository contains the core runtime, multiple engine adapters, a rich sample library, and a stub-based test runner for validating agent programs without real LLM credentials.

Individual File Summaries

File	Summary
./.agents/skills/rig/engines/anthropic.ts	Implements the Anthropic engine adapter, translating Rig agent calls into Anthropic SDK requests with tool-use support.
./.agents/skills/rig/engines/codex.ts	Implements the Codex engine adapter using the OpenAI Codex SDK for threaded agent execution.
./.agents/skills/rig/engines/gemini.ts	Implements the Gemini engine adapter by spawning a subprocess and communicating over stdio.
./.agents/skills/rig/engines/pi.ts	Implements the Pi engine adapter integrating the earendil-works Pi agent core and AI provider.
./.agents/skills/rig/engines/utils.ts	Provides shared utility helpers for engine adapters, such as normalizing tool parameter schemas to the required object shape.
./.agents/skills/rig/globals.ts	Exposes ambient workflow context helpers (call, pipeline, parallel) as module-level functions that delegate to the active workflow context.
./.agents/skills/rig/rig.ts	Mirror of the canonical core runtime; serves as the agent-local copy used by the .agents workspace.
./scripts/haiku.integration.test.ts	Integration test that spawns the rig launcher as a child process and validates end-to-end agent execution against a real or stubbed backend.
./scripts/run-sample.test.ts	Stub-based sample runner that imports each sample file under a mocked Copilot SDK, synthesizes shape-conforming output from the output schema, and asserts timing and correctness.
./skills/rig/engines/anthropic.ts	Canonical Anthropic engine adapter; same role as the .agents copy but is the source-of-truth file for the skills workspace.
./skills/rig/engines/codex.ts	Canonical Codex engine adapter for the skills workspace, wrapping the OpenAI Codex SDK.
./skills/rig/engines/gemini.ts	Canonical Gemini engine adapter for the skills workspace, launching Gemini via subprocess stdio.
./skills/rig/engines/pi.ts	Canonical Pi engine adapter for the skills workspace, integrating the Pi AI provider.
./skills/rig/engines/utils.ts	Canonical shared utilities for engine adapters in the skills workspace.
./skills/rig/globals.ts	Canonical ambient context helpers for the skills workspace.
./skills/rig/rig.ts	The primary Rig core runtime: defines agent, schema helpers (s.), prompt intents (p.), workflow orchestration, repair, and the Copilot SDK engine.
./src/engines/anthropic.test.ts	Unit tests for the Anthropic engine adapter, mocking the SDK and asserting correct tool-call translation.
./src/engines/codex.test.ts	Unit tests for the Codex engine adapter, verifying thread lifecycle and tool execution.
./src/engines/copilot.test.ts	Unit tests for the Copilot engine adapter, covering session creation, send/wait, and disconnect flows.
./src/engines/gemini.test.ts	Unit tests for the Gemini engine adapter, mocking subprocess streams and verifying message parsing.
