ReadyAgents Core 0.8.2

MCP Registry metadata is now included for the local stdio MCP server. The PyPI package README carries the ownership marker.

ReadyAgents Core 0.8.1

readyagents is on PyPI. Install docs now match that.

pip install readyagents
readyagents new my-flow

The wheel does not ship examples/. Clone-and-run still uses examples/calc_pipeline.yaml.

ReadyAgents Core 0.8.0

ReadyAgents Core 0.8.0

0.8.0. This package is not on PyPI. Install from a clone (pip install -e .).

First-run clip: https://www.youtube.com/watch?v=D69o_HTGNQk

Eval CLI, local packs, workspace list_dir, extra new templates, unified --json. Still local. No always-on.

What is new

• readyagents eval scores fixture suites without a network or API keys
• --pack loads a workspace pack without an entry point
• list_dir lists a workspace without an MCP filesystem server
• readyagents new --template foreach|agent-tools|gated
• --json includes ok and command on operator-facing commands

Try it (no API keys)

Requires Python 3.11+.

git clone https://github.com/readyagents/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

Safety

Core still has no always-on listener, scheduler, hosted control plane, extra database, or billing. Packs are not for sale.

Full notes: see CHANGELOG.md (## 0.8.0) and RELEASE_NOTES.md.

ReadyAgents Core 0.7.0

ReadyAgents Core 0.7.0

Honest composition resume and a real MCP client. Still local. No always-on. Install from this repo (not claiming PyPI publish).

What is new

• Include / parallel resume snapshots: successful child nodes and sibling branches are not re-run
• MCP client: one stdio session per named server; inputSchema on tools; cwd confined to the workspace
• Pause notify (on_pause_url) uses the same public-IP pin as http_get; HITL still pauses if notify fails
• Template filters default / len / join and condition and / or / not (no Python eval)

Try it (no API keys)

pip install -e .
readyagents run examples/foreach_calc.yaml
readyagents run examples/composed_gate.yaml --approve gate

Safety

Core still has no always-on listener, scheduler, hosted control plane, extra database, or billing.

Full notes: see CHANGELOG.md (## 0.7.0) and RELEASE_NOTES.md.

ReadyAgents Core 0.6.0

ReadyAgents Core 0.6.0

List-shaped local YAML, inspectable tool-use, operable run store. No always-on. Install from this repo (not claiming PyPI publish).

What is new

• Bounded sequential foreach (items, max_items, resume skips ok items). Example: examples/foreach_calc.yaml
• json_set / json_merge builtins (size-capped). Example: examples/json_mutate.yaml
• Agent tools: allowlist + max_tool_rounds; ToolError is a tool observation; tool_rounds on the run record. Example: examples/agent_tools.yaml --dry-run
• Pause prompt persisted; runs delete / runs gc (paused kept unless --include-paused); Ctrl-C → cancelled; pending cleared on resume/success

Try it (no API keys)

pip install -e .
readyagents run examples/foreach_calc.yaml
readyagents run examples/json_mutate.yaml
readyagents run examples/agent_tools.yaml --dry-run
readyagents run examples/approval_gate.yaml

Safety

Core still has no always-on listener, scheduler, hosted control plane, extra database, or billing. Those remain pack material.

Full notes: see CHANGELOG.md (## 0.6.0) and RELEASE_NOTES.md.

ReadyAgents Core 0.4.0

ReadyAgents Core 0.4.0

Docs honesty after 0.3.0. No new nodes. No always-on. Install from this repo (not claiming PyPI publish).

What this labels

• CHANGELOG Unreleased no longer lists items already in 0.3.0 (#24)
• first-ten-minutes matches README: readyagents new my-flow (default is pipeline) (#25)
• Leftover marks extras, size caps, DNS rebind, parallel timeout/retry, packs JSON, and Makefile/CONTRIBUTING smoke as shipped (#26)

The engine is still 0.3.0's.

Safety

Core still has no always-on listener, scheduler, hosted control plane, extra database, or vendor secrets SDK. Those remain waitlisted packs, not for sale.

Full notes: see CHANGELOG.md (## 0.4.0).

ReadyAgents Core 0.3.0

ReadyAgents Core 0.3.0

Open-core agent workflow engine + MCP toolkit. BYOK. Install from this repo (not claiming PyPI publish).

Highlights

• Structured JSON logs, per-node token/cost + budgets
• Model fallback + circuit breaker; opt-in LLM cache
• External decision injection: readyagents decide / --decision-file (no always-on HTTP listener)
• Secrets-manager hooks (env remains default BYOK), audit trail, RBAC + optional PII redaction
• Pydantic output_schema on agent nodes
• readyagents.testing helpers; Dockerfile + compose; multi-gate / connector / signed Gate example packs

Safety

Core still has no always-on listener, scheduler, hosted control plane, extra database, or vendor secrets SDK. Those remain waitlisted packs, not for sale.

Full notes: see CHANGELOG.md (## 0.3.0).

ReadyAgents Core 0.2.0

ReadyAgents Core 0.2.0

The first release that feels like a toolkit you can trust for one-shot work.

ReadyAgents Core is still the free, open-source engine: YAML workflows, BYOK, builtin tools, MCP optional, packs later. 0.1.0 proved clone-and-run. 0.2.0 is the reliability and operator-experience layer.

Apache-2.0. No vendor keys. No always-on runtime in core.

Why this release matters

A careful engineer running agent graphs needs four things a playground does not:

1. A human can stop a run. Approval nodes pause (they do not hang a TTY).
2. A failed step is not a lost run. State is written after every node; resume continues from the last success.
3. You can see what happened. runs list / show / inspect / replay.
4. Starting a project is boring in the good way. readyagents new writes a workflow, README, and .env.example.

That is the difference between a demo engine and something you would actually use.

What is new

Human-in-the-loop

- id: gate
  type: approval
  prompt: "Release payment of {{total}}?"
  then: receipt
  else: denied

Without a decision the CLI exits 2, persists paused, and tells you how to continue:

readyagents run examples/approval_gate.yaml
readyagents resume <run_id> --approve gate
# or
readyagents run examples/approval_gate.yaml --approve gate

Durable local runs

JSON under .readyagents/runs/<id>.json, written atomically after each node.

readyagents runs list
readyagents runs show <run_id>
readyagents runs show <run_id> --json
readyagents runs replay <run_id>
readyagents resume <run_id> --approve gate

Filters: --status, --workflow, --limit. Logs include run= and node=.

Composition

• type: parallel — independent branches concurrently (examples/fanout_gate.yaml)
• type: include — run another workflow file (examples/include_demo.yaml)

Scaffolding

readyagents new my-flow                     # approval template (default)
readyagents new my-flow --template basic
readyagents new my-flow --template research # parallel + approval

Each writes workflow.yaml, README.md, and .env.example.

Dry-run

Agent nodes report usage: estimated_tokens=…. LLM examples that parse_json after an agent no longer crash on the dry-run stub.

Try it (no API keys)

pip install -e .
readyagents run examples/calc_pipeline.yaml
readyagents runs list

readyagents run examples/approval_gate.yaml --approve gate
readyagents run examples/fanout_gate.yaml --approve gate
readyagents run examples/include_demo.yaml

readyagents new demo --template research
readyagents run demo/workflow.yaml --approve publish

With keys, the existing research / triage / review examples still work. --dry-run still walks them without calling a vendor.

What we deliberately left out of core

These belong in waitlisted packs, not for sale:

• Always-on / continuous workers and schedulers
• Hosted control plane, teams, SSO
• Distributed recovery and remote run stores
• Alerting, paging, billing

Core stays small so those can plug in via readyagents.packs.

Compatibility

• Python 3.11+
• Existing 0.1.0 workflow YAML still runs. New node types (approval, parallel, include) are additive.
• CLI exit code 2 now means “paused for approval”, not a generic failure.
