Global Summary

Rig is a minimal TypeScript multi-agent harness centered on skills/rig/rig.ts, which provides the core agent, workflow, p.* prompt intents, s.* schema helpers, and runtime adapters for GitHub Copilot, Anthropic, Codex, Gemini, and Pi engines. The repository also contains a comprehensive test suite (vitest), a stub-based sample runner, and a growing library of sample agents demonstrating patterns from simple file analysis to multi-agent orchestration and end-to-end release workflows.

Individual File Summaries

File	Summary
./.agents/skills/rig/engines/anthropic.ts	Implements the anthropicEngine adapter wrapping the Anthropic SDK to run rig agents via Claude models, handling tool calls and streaming responses.
./.agents/skills/rig/engines/codex.ts	Implements the codexEngine adapter using the OpenAI Codex SDK, translating rig agent calls into Codex thread-based interactions.
./.agents/skills/rig/engines/gemini.ts	Implements the geminiEngine adapter that spawns the Gemini CLI process and communicates via JSON-RPC for rig agent sessions.
./.agents/skills/rig/engines/pi.ts	Implements the piEngine adapter integrating the Pi agent SDK to run rig agents with Pi AI models and tools.
./.agents/skills/rig/engines/utils.ts	Provides a shared utility (objectToolSchema) that normalises rig Tool definitions into JSON Schema objects required by LLM providers.
./.agents/skills/rig/globals.ts	Exports ambient workflow context helpers (call, pipeline, parallel) as module-level functions that delegate to the active rig workflow context.
./.agents/skills/rig/rig.ts	Core rig runtime (agent copy under .agents/): declarative agent/workflow construction, typed schemas, prompt intents, sub-agent delegation, and Copilot SDK integration.
./scripts/haiku.integration.test.ts	Integration test that spawns a real rig process (haiku sample) and asserts it produces expected output end-to-end.
./scripts/run-sample.test.ts	Vitest test runner for all sample agents using a stub Copilot SDK client that generates shape-conforming output from <output_schema> blocks without real API calls.
./skills/rig/engines/anthropic.ts	Source copy of the Anthropic engine adapter (mirrors .agents/skills/rig/engines/anthropic.ts).
./skills/rig/engines/codex.ts	Source copy of the Codex engine adapter (mirrors .agents/skills/rig/engines/codex.ts).
./skills/rig/engines/gemini.ts	Source copy of the Gemini engine adapter (mirrors .agents/skills/rig/engines/gemini.ts).
./skills/rig/engines/pi.ts	Source copy of the Pi engine adapter (mirrors .agents/skills/rig/engines/pi.ts).
./skills/rig/engines/utils.ts	Source copy of the engine utility helpers (mirrors .agents/skills/rig/engines/utils.ts).
./skills/rig/globals.ts	Source copy of the ambient workflow helpers (mirrors .agents/skills/rig/globals.ts).
./skills/rig/rig.ts	Primary source of the rig runtime: all agent/workflow/schema/prompt-intent APIs, the copilot engine, and the runLauncherCli entry point.
./src/engines/anthropic.test.ts	Unit tests for the Anthropic engine adapter, verifying model selection, tool call handling, and error propagation using mocked Anthropic SDK.
./src/engines/copilot.test.ts	Unit tests for the Copilot engine adapter, covering URI/stdio transport selection, session creation, and model forwarding with mocked Copilot SDK.
./src/rig.test.ts	Core unit tests for the rig harness: agent definition, schema validation, prompt intent rendering, sub-agent delegation, and repair loop behaviour.
./vitest.config.ts	Vitest configuration that sets up the "rig" path alias resolving to skills/rig/rig.ts and points the test environment at the source files.
