feat: installer detects Python version and warns when 3.11+ (tomllib) is missing (#2466)
* feat: installer detects Python version and warns when 3.11+ (tomllib) is missing

Several BMAD features need Python at runtime: memlog (3.8+) and the TOML
config resolution scripts (3.11+ for stdlib tomllib). Users install into
varied environments (Linux, Windows, WSL, Docker) where Python may be
missing or too old, and previously only found out via runtime errors.

The installer now probes PATH at startup (py -3 / python3 / python) and
classifies the result: 3.11+ passes silently with a success line; 3.8-3.10
or missing/too-old Python gets a warning naming exactly which features
degrade, plus per-platform install hints. The warning requires an explicit
ack — continue (fix later, no reinstall needed) or quit and re-run after
installing Python. Warn-don't-block: most of BMAD works without Python, so
the install is never refused. In --yes mode the warning logs and continues
without prompting.

* fix: align Python check with runtime truth (python3) and harden edge cases

Review fixes for the installer Python check:

- Probe python3 first on all platforms: every runtime call site invokes a
  literal python3, so only that command vouches for BMAD features. Python
  found via py/python now gets an explicit mismatch warning instead of a
  false "all BMAD features supported".
- Treat closed/piped stdin as non-interactive (in addition to --yes) so
  scripted installs no longer silently exit 0 via clack's cancel path.
- Retry probes with shell:true on win32 EINVAL (CVE-2024-27980 hardening
  rejects .bat/.cmd shims like pyenv-win's without a shell).
- Add Suite 46 branch tests for checkPythonEnvironment with stubbed
  detection, prompts, and process.exit.

🚀 What's Next for BMad?

V6 is here and we're just getting started! The BMad Method is evolving rapidly with optimizations including Cross Platform Agent Team and Sub Agent inclusion, Skills Architecture, BMad Builder v1, Dev Loop Automation, and so much more in the works.

📍 Check out the complete Roadmap →


Quick Start

Prerequisites: Node.js v20.12+ · Python 3.10+ · uv

npx bmad-method install

Want the newest prerelease build? Use npx bmad-method@next install. Expect higher churn than the default install.

Follow the installer prompts, then open your AI IDE (Claude Code, Cursor, etc.) in your project folder.

Non-Interactive Installation (for CI/CD):

npx bmad-method install --directory /path/to/project --modules bmm --tools claude-code --yes

Override any module config option with --set <module>.<key>=<value> (repeatable). Run --list-options [module] to see locally-known official keys (built-in modules plus any external officials cached on this machine):

npx bmad-method install --yes \
  --modules bmm --tools claude-code \
  --set bmm.project_knowledge=research \
  --set bmm.user_skill_level=expert

See all installation options

Not sure what to do? Ask bmad-help — it tells you exactly what's next and what's optional. You can also ask questions like bmad-help I just finished the architecture, what do I do next?

Modules

BMad Method extends with official modules for specialized domains. Available during installation or anytime after.

Module Purpose
BMad Method (BMM) Core framework with 34+ workflows
BMad Builder (BMB) Create custom BMad agents and workflows
Test Architect (TEA) Risk-based test strategy and automation
Game Dev Studio (BMGD) Game development workflows (Unity, Unreal, Godot)
Creative Intelligence Suite (CIS) Innovation, brainstorming, design thinking

Web Bundles

V4 shipped web bundles. V6 brings them back, new and improved.

Web bundles package selected BMad skills for installation as Google Gemini Gems and ChatGPT Custom GPTs. Use them to do the upfront planning work (brainstorming, product briefs, PRDs, PRFAQs, UX specs, market and industry research) in your web LLM subscription, then bring the polished artifacts into your IDE for implementation. Planning runs on a flat-rate subscription instead of metered IDE tokens, which is a meaningful cost saver on longer engagements. Choose the best model available to you in Gemini or ChatGPT.

Current shelf: brainstorming, product brief, PRFAQ, PRD, UX, market & industry research.

Browse and install at bmadcode.com/web-bundles. One card per bundle, inline install steps for Gemini and ChatGPT, one-click ZIP download. See the web bundles guide for the concept.
