Yoke lets you reuse them from code — one `Harness` that drives both. <a href="#quickstart">Quickstart</a> · <a href="#how-it-compares">How it compares</a> · <a href="#sessions">Sessions</a> · <a href="#skills">Skills</a> · <a href="#subagents">Subagents</a> · <a href="#workflows">Workflows</a> · <a href="#goals">Goals</a> · <a href="#surfaces">Surfaces</a> · <a href="#cli">CLI</a> ## Quickstart ```bash pip install almanac-yoke ``` Install a provider extra when you want Yoke to manage that SDK directly: ```bash pip install 'almanac-yoke[claude]' # or [codex], or [all] ``` Define an agent, pick a harness, run: ```python from pathlib import Path from yoke import Agent, Goal, Harness agent = Agent( instructions="You are a careful maintainer. Make small, safe changes.", goal=Goal("Finish the requested implementation safely."), ) harness = Harness("codex", agent=agent, cwd=Path.cwd()) result = await harness.run("Implement the bundle loader.") print(result.output) ``` Swap `"codex"` for `"claude"` and the same agent runs there. Your existing Claude Code or ChatGPT login is all it needs — no API keys. Embedding applications can observe a one-shot run while it is happening: ```python from yoke import RunOptions seen = [] result = await harness.run( "Implement the bundle loader.", RunOptions(on_event=seen.append), ) assert tuple(seen) == result.events ``` `on_event` is a synchronous callback receiving each normalized `Event` once. It is runtime-only—it is excluded from serialized options and agent folders. Live callback delivery is supported by the Claude Python SDK and Codex app-server surfaces. Passing `on_event` selects one of those surfaces when the surface is automatic, and raises `UnsupportedFeature` when an explicitly selected surface cannot deliver callbacks. Use `harness.stream(...)` for a portable event iterator. ## How it compares The question that places Yoke: **who runs the agent?** | | The agent runs in | Yoke | | --- | --- | --- | | [Claude Agent SDK](https://code.claude.com/docs/en/agent-sdk/overview) · [Codex SDK](https://developers.openai.com/codex/sdk) | the lab's harness — one provider each | builds on them. They are the surfaces Yoke drives; one definition runs on both. | | [Pydantic AI](https://ai.pydantic.dev) · [LangChain](https://www.langchain.com) | your process — a loop you assemble over model APIs | starts from a different premise: the harness already is the agent, so there is no loop to assemble. | | [Eve](https://github.com/vercel/eve) | Eve's own durable runtime, deployed on Vercel | is closest in spirit — an agent is a directory — but compiles that directory onto Claude and Codex instead of shipping a runtime. | ## Sessions ```python session = await harness.start() plan = await session.run("Draft the migration plan.") step = await session.run("Apply step one.") await session.close() ``` State lives with the provider; Yoke holds the handle. Sessions are native on every surface except the Codex CLI, where they work by resuming threads. ## Skills ```python from yoke import Skill agent = Agent( instructions="You are a careful maintainer.", skills=(Skill(path=Path("skills/source-grounding")),), ) ``` A skill is a folder with a `SKILL.md`. Claude loads skills natively, the Codex app-server mounts them as native skill roots, and other surfaces get them compiled to files. ## Subagents ```python agent = Agent( instructions="You are a careful maintainer.", subagents={ "reviewer": Agent( description="Find correctness and architecture risks.", instructions="Review concretely. Prefer file and line evidence.", ), }, ) ``` A subagent is just another `Agent`. Claude runs declared subagents through its native Agent tool. Codex app-server derives temporary custom-agent TOML and the parent selects it with `spawn_agent(agent_type=..., fork_turns="none")`. Yoke does not silently use a generic child: an incompatible Codex model/backend fails honestly. Codex SDK/CLI surfaces retain their documented lowerings. Runtime files are derived outside `cwd` and removed when the session closes. Set `Harness(runtime_root=...)` to choose their parent cache directory. This is different from `agent.bundle(...).write(...)`, which explicitly exports durable provider files for a project. A later deployment reclaims runtime directories whose owning process exited before normal cleanup. ## Workflows ```python from yoke import Step, Workflow, WorkflowOptions workflow = Workflow( name="review", steps=( Step(name="draft", agent="main", prompt="Draft release notes."), Step( name="review", agent="reviewer", depends_on=("draft",), prompt="Review this draft: {draft}", ), ), ) result = await harness.workflow( workflow, options=WorkflowOptions(timeout_seconds=120, step_timeout_seconds=60), ) ``` A workflow is a small dependency graph over the agent and its subagents; `main` is the reserved name for the root agent, and `WorkflowOptions` bounds the run. Neither provider has a native equivalent yet, so workflows are portable Yoke constructs — they run the same on every surface. ## Goals ```python from yoke import Goal session = await session.set_goal(Goal("Land the bundle loader.", token_budget=200_000)) print(await session.get_goal()) ``` A goal is intent that outlives a single prompt. On the Codex app-server it is real thread state — readable, replaceable, clearable. Everywhere else it compiles into the provider loop, and `explain()` tells you which you got. ## No pretending Claude and Codex expose different primitives, and Yoke does not flatten them into a weak common denominator. The capability map is part of the API: ```python for row in harness.explain().reports: print(row.feature, row.support, row.lowering) # native, compiled, emulated, unsupported ``` | Feature | Claude SDK | Codex app-server | Codex SDK | Codex CLI | | --- | --- | --- | --- | --- | | Sessions | native | native | native | resume-based | | Streaming | native | native | native transport | JSONL/process | | Skills | native | native skill roots | compiled | files/compiled | | Subagents | native | compiled → native tool | compiled | files/compiled | | Goals | provider loop | native state | compiled context | provider loop | | Workflows | portable Yoke | portable Yoke | portable Yoke | portable/limited | | Permissions/hooks | native callbacks | native request events | sandbox/approval | flags/config | ## Agents are folders Everything defined in Python can be saved as files, edited by hand, and loaded back: ```python agent.save("agent") agent = Agent.from_folder("agent") ``` ```text agent/ agent.yaml instructions.md skills/ source-grounding/SKILL.md subagents/ reviewer/ workflows/ ship/ ``` Provider files like `.claude/` and `.codex/` are compiled from this source, only when you ask: ```python agent.bundle(provider="codex", surface="codex_cli").write(Path.cwd()) ``` ## Surfaces This is the deeper layer: ```text agent definition -> provider surface -> real harness ``` Each provider ships more than one way in. `Harness("codex")` picks the strongest one for you (the app-server); address a surface directly when you require an exact one: | Surface | What it is | | --- | --- | | `codex:app` | Codex app-server — sessions, native goals, skill roots | | `codex:sdk` | Codex Python SDK | | `codex:cli` | Codex CLI — `codex exec`, resumable threads | | `claude:sdk` | Claude Agent SDK for Python | `discover` reports what this machine already has — surfaces installed, logins ready, models available — and picks the first ready surface satisfying the requested features: ```python from yoke import Feature, discover found = await discover("codex", Path.cwd(), agent) # reuses your local login for surface in found.surfaces: print(surface.surface, [model.id for model in surface.models]) harness = found.harness(Feature.STREAMING) ``` Claude also accepts runtime-only `Credentials` (redacted, never serialized); Codex logins persist provider state, so they go through an explicit `await harness.login(...)`. ## CLI The same agents and folders, from the shell: ```bash yoke run agents codealmanac "Review this repo" yoke explain agents codealmanac yoke status agents codealmanac yoke install agents codealmanac --provider codex:cli yoke runs ``` CLI runs leave inspectable snapshots under `.yoke/runs/`. SDK users can persist returned results explicitly with `RunStore.at(".yoke/runs").record(result)`. ## Status Yoke is an early alpha. Everything shown above is built and smoke-tested against live providers. The API may still change before 1.0; durable workflow execution and typed coverage of every provider-specific option remain future work. - [Quickstart](docs/quickstart.md) - [Reference](docs/reference.md) - [Design notes](docs/notes/) — every decision, recorded - [Contributing](CONTRIBUTING.md) - [Security](SECURITY.md) Apache-2.0.
