Global Summary

Rig is a minimal TypeScript agent harness that provides declarative, typed agent construction with schema helpers (s.*), prompt intents (p.*), and multi-engine support (Copilot, Anthropic, Gemini, Codex, Pi). It exposes a CLI launcher, sub-agent delegation, workflow orchestration, and a vitest-based stub runner for dry-run validation of sample agents.

Individual File Summaries

File	Summary
.agents/skills/rig/engines/anthropic.ts	Implements the Anthropic engine adapter for Rig, translating agent calls into Anthropic SDK requests with tool-use support.
.agents/skills/rig/engines/codex.ts	Implements the Codex (OpenAI) engine adapter, wiring agent invocations through the @openai/codex-sdk client.
.agents/skills/rig/engines/gemini.ts	Implements the Gemini engine adapter using a spawned subprocess and UUID-tracked sessions for agent communication.
.agents/skills/rig/engines/pi.ts	Implements the Pi engine adapter integrating @earendil-works/pi-agent-core for agent invocations.
.agents/skills/rig/engines/utils.ts	Shared utility for converting Rig tool definitions into object-typed JSON Schema tool descriptors for engine adapters.
.agents/skills/rig/globals.ts	Provides ambient workflow context helpers (call, pipeline, parallel) importable from rig/globals for module-level orchestration.
.agents/skills/rig/rig.ts	Mirror of the core Rig runtime under .agents/, kept in sync with skills/rig/rig.ts for agent-context imports.
scripts/haiku.integration.test.ts	Integration test that spawns the Rig CLI in a subprocess to verify end-to-end execution against a real or mocked backend.
scripts/run-sample.test.ts	Vitest-based sample runner that stubs the Copilot SDK and validates all sample agents produce schema-conforming output.
skills/rig/engines/anthropic.ts	Anthropic engine adapter (canonical source) providing anthropicEngine() factory for use in Rig programs.
skills/rig/engines/codex.ts	Codex engine adapter (canonical source) providing codexEngine() factory for OpenAI Codex-backed agents.
skills/rig/engines/gemini.ts	Gemini engine adapter (canonical source) providing geminiEngine() factory with subprocess-based session management.
skills/rig/engines/pi.ts	Pi engine adapter (canonical source) providing piEngine() factory wrapping the Pi AI agent SDK.
skills/rig/engines/utils.ts	Canonical shared utility for building object-schema tool descriptors consumed by all engine adapters.
skills/rig/globals.ts	Canonical globals module exposing ambient workflow helpers for pipeline and parallel agent orchestration.
skills/rig/rig.ts	Core Rig runtime (~3 300 lines): defines agent, p, s, copilotEngine, schemas, prompt intents, sub-agent delegation, addons, and the CLI launcher.
src/engines/anthropic.test.ts	Unit tests for the Anthropic engine adapter, mocking the Anthropic SDK to verify request/response translation.
src/engines/codex.test.ts	Unit tests for the Codex engine adapter, mocking @openai/codex-sdk to verify invocation and output handling.
src/engines/copilot.test.ts	Unit tests for the Copilot engine adapter, mocking @github/copilot-sdk session creation and response parsing.
src/rig.test.ts	Main unit test suite for the Rig harness covering agent definition, invocation, validation, repair, and prompt intent resolution.
