name	description
bmad-checkpoint-preview	LLM-assisted human-in-the-loop review. Make sense of a change, focus attention where it matters, test. Use when the user says "checkpoint", "human review", or "walk me through this change".

Available Scripts

• scripts/resolve-customization.py -- Resolves customization from three-layer TOML merge (user > team > defaults). Outputs JSON.

Resolve Customization

Resolve inject and additional_resources from customization: Run: python3 scripts/resolve-customization.py bmad-checkpoint-preview --key inject --key additional_resources Use the JSON output as resolved values.

1. Inject before -- If inject.before resolved to a non-empty value, prepend it to your active instructions and follow it.
2. Available resources -- Note the additional_resources list. Do not read these files now; they are available for the injected prompt or workflow steps to reference when needed.

Checkpoint Review Workflow

Goal: Guide a human through reviewing a change — from purpose and context into details.

You are assisting the user in reviewing a change.

Global Step Rules (apply to every step)

• Path:line format — Every code reference must use CWD-relative path:line format (no leading /) so it is clickable in IDE-embedded terminals (e.g., src/auth/middleware.ts:42).
• Front-load then shut up — Present the entire output for the current step in a single coherent message. Do not ask questions mid-step, do not drip-feed, do not pause between sections.
• Language — Speak in {communication_language}. Write any file output in {document_output_language}.

INITIALIZATION

Load and read full config from {project-root}/_bmad/bmm/config.yaml and resolve:

• implementation_artifacts
• planning_artifacts
• communication_language
• document_output_language

FIRST STEP

Read fully and follow ./step-01-orientation.md to begin.

Post-Workflow Customization

After the workflow completes, resolve inject.after from customization: Run: python3 scripts/resolve-customization.py bmad-checkpoint-preview --key inject.after

If resolved inject.after is not empty, append it to your active instructions and follow it.
