ReadyAgents runs YAML agent workflows locally. Every node is checkpointed, so a run pauses for human approval, resumes from where it stopped, and replays offline as a regression test. Your keys, your machine, no daemon.

Site: readyagents.dev. Repo: github.com/readyagentsdev/readyagents-core.

Tried it? Open an I-ran-this issue. We are not launching. We are listening.

This repository is the free core. You keep the provider account and the bill. Install with pip install readyagentsdev, or from this clone.

60-second start

Requires Python 3.11–3.14 on Linux, macOS, or Windows. Current version is 2.0.8. Install with pip install readyagentsdev, or from this clone. The 2 versions the core contract only; extras carry their own maturity tiers.

pip install readyagentsdev
readyagents new my-flow
readyagents run my-flow/workflow.yaml
readyagents runs list

The wheel ships the example workflows too — no clone needed:

readyagents new f --from-example calc_pipeline
readyagents run f/workflow.yaml

readyagents new --list-examples shows all of them.

Or from a clone:

git clone https://github.com/readyagentsdev/readyagents-core.git
cd readyagents-core
python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -e .
readyagents run examples/calc_pipeline.yaml
readyagents runs list
readyagents doctor

readyagents run examples/calc_pipeline.json is the same graph.

What it does

Define agent workflows as YAML or JSON (nodes + edges)
Run agent, tool, condition, transform, approval, parallel, include, foreach, and decide nodes. Agent nodes may declare a tools: allowlist for a bounded tool-use loop. type: decide is experimental; see docs/decisions.md.
Persist after every node and resume a paused or failed run from the last successful node
Inspect past runs: readyagents runs list / show / replay / fork / diff / freeze / report (local HTML)
Scaffold a starter: readyagents new my-flow (basic, approval, research, pipeline, review, foreach, agent-tools, gated)
Builtin tools with zero extra servers: now, calc, json_get, list_dir, read_file, write_file
MCP client and server (readyagents mcp serve, readyagents mcp probe) with official tasks and MRTR approvals
Policy, spend ledger, budgets and caps: per-node token/cost, --estimate / --max-spend caps, model fallback, JSON logs

Beyond the core, 40+ opt-in extras ship in the same install — teams, studio, browser, knowledge, distillation, registry, environments and more. Each is listed with its maturity tier and its limits in docs/extras.md. None of them is required, and none of them changes how the core behaves.

The agent firewall (taint, tool policy, MCP pinning — security model, policy) is defence in depth, not a solution to prompt injection.

`readyagents batch PATH --input-file FILE [--concurrency N] [--max-spend USD] [--out FILE]`	Foreground: one workflow, many JSONL/CSV rows (opt-in)
`readyagents attest RUN_ID`	Data-residency attestation (technical evidence, not legal compliance)

`readyagents identity whoami`	Workload fingerprint (never the private key)
`readyagents runs list`	List persisted runs
`readyagents runs show RUN_ID`	Node timeline + stored state (`inspect` is an alias)
`readyagents runs report RUN_ID`	Local HTML summary of a run
`readyagents runs replay RUN_ID`	New run from stored inputs
`readyagents runs delete RUN_ID --yes`	Delete one local run record
`readyagents runs gc --yes`	Prune succeeded/failed/cancelled runs (paused kept; in-window records refused unless `--override-retention`)

Install extras

LLM and MCP extras are optional.

pip install "readyagentsdev[openai]"
pip install "readyagentsdev[anthropic]"
pip install "readyagentsdev[gemini]"
pip install "readyagentsdev[bedrock]"
pip install "readyagentsdev[vertex]"
pip install "readyagentsdev[mcp]"
pip install "readyagentsdev[all]"
pip install "readyagentsdev[image]"
pip install "readyagentsdev[pdf]"
pip install "readyagentsdev[audio]"
pip install "readyagentsdev[table]"

From a clone, the same extras are pip install -e ".[openai]" (and anthropic / gemini / bedrock / vertex / mcp / all). The optional [otel] extra is not included in [all]; it starts no collector (see observability.md). The optional [sign] extra (Ed25519 artifact signatures), [jwt], [gemini], [bedrock], [vertex], [image], [pdf], [audio], and [table] extras are also not in [all]. Unsigned default runs never import them. Codecs are extras; core installs stay text-only. Pandas is optional for table ops; stdlib is sufficient.

Then cp .env.example .env and paste your own keys. Core workflows that only use builtin tools do not need extras, keys, or Node.js.

docker compose run --rm readyagents run examples/calc_pipeline.yaml
make smoke

What is not in this repository

Always-on packs are waitlisted and not for sale.

Always-on / continuous workers are not in Core. The optional readyagents-pack-continuous distribution (separate repository, not a Core extra) can run configured workflows from an explicit foreground command. Installing Core still starts no scheduler or listener.

Hosted control plane. Hosted recovery and remote run stores. SSO, multi-tenant teams, billing.

The core has persist, resume, and approval pauses for a local one-shot. It does not run always-on.
