goose: what’s new in v1.56.0 and our verdict

Our verdict

Pick goose if you want an open-source agent with real subagent controls; v1.56.0 is a solid, subagent-heavy update.

Tested. Tested 2026-10-25 (America/Chicago). Ran the official download_cli.sh (read first); it stopped because bzip2 is missing here, so we unpacked the same release archive with Python. "goose --version" printed 1.56.0. "goose run --no-session" with provider ollama (local model): attempt 1 called the edit tool but the text did not match and the file was unchanged; attempt 2, with exact before and after strings, printed "Edited calc.py" and changed a-b to a+b. Not tested: subagents, resume and limits, or the desktop app. Test environment: Linux x86_64 box with 8 CPUs and no GPU, no vendor account or API key. Agent tools were pointed at a local open-weight model (Qwen2.5-3B-Instruct, 4-bit, served by Ollama 0.40.11), so we tested the tool, not any vendor's hosted models. Full log: /tests/goose.

Evidence

Tested (smoke test, 2026-10-25, local Qwen2.5-3B-Instruct, not vendor models). A smoke test is not a benchmark.

What we ran

Unpacked the official release archive (the install script stopped on a missing bzip2), goose --version printed 1.56.0, and ran 'goose run' with a local Ollama provider; attempt 1 failed to change the file, attempt 2 with exact strings changed a-b to a+b.

Model used

Qwen2.5-3B-Instruct (4-bit), a small local open-weight model served by Ollama 0.40.11; no vendor-hosted model was used

Environment

Linux x86_64 box, 8 CPUs, no GPU; no vendor account, login or API key

Not tested

Subagents, resume and limits, the desktop app.

• v1.56.0: Automatic thinking level operation for improved model reasoning.
• v1.56.0: Windows NSIS installer for the desktop app, and a new IO Intelligence provider.
• v1.56.0: Replaces PCTX code mode with a Boa JavaScript runtime.

How to set it up: Install goose and run your first session

Install steps come from the vendor's docs. We ran the install and a short real task on 2026-10-25; see the test notes above for what was and was not covered.

1. Install the CLI

   The README gives a one-line installer. Read the script first if you prefer.

   curl -fsSL https://github.com/aaif-goose/goose/releases/download/stable/download_cli.sh | bash

2. Pick a provider

   Run goose and follow the prompts to connect a model provider. goose works with any LLM according to its description.

3. Try subagents

   If you use delegated subagents, v1.56.0 lets you cap how many run at once with an environment variable.

   export GOOSE_MAX_CONCURRENT_SUBAGENTS=3
