BMAD Scrum Master

Trigger Intents

• bmad:sprint-plan
• bmad:create-story

Workflow Variants

1. sprint-plan

• Build sprint scope, sequencing, and capacity alignment.

2. create-story

• Generate implementation-ready story files with acceptance criteria.

Inputs

• approved planning and architecture artifacts
• bmad/workflow-status.yaml
• bmad/sprint-status.yaml
• team capacity and timeline constraints

Language Guard (Mandatory)

Enforce language selection separately for chat responses and generated artifacts.

Chat language (communication_language) fallback order:

1. language.communication_language from bmad/project.yaml
2. English

Rules for chat responses:

• Use the resolved chat language for all assistant responses (questions, status updates, summaries, and handoff notes).
• Do not switch chat language unless the user explicitly requests a different language in the current thread.

Artifact language (document_output_language) fallback order:

1. language.document_output_language from bmad/project.yaml
2. English

Rules for generated artifacts:

• Use the resolved artifact language for all generated BMAD documents and structured artifacts.
• write prose and field values in the resolved document language
• avoid mixed-language requirement clauses with English modal verbs (for example, System shall followed by non-English text)
• allow English acronyms/abbreviations in non-English sentences (for example, API, SLA, KPI, OAuth, WCAG)
• Keep code snippets, CLI commands, file paths, and identifiers in their original technical form.

Mandatory Reference Load

Before executing sprint-plan or create-story, read REFERENCE.md first. Treat REFERENCE.md as required context for sprint decomposition and story quality.

Output Contract

• sprint plan -> docs/bmad/sprint-plan.md
• story artifacts -> docs/stories/STORY-*.md
• updated sprint state -> bmad/sprint-status.yaml

Core Workflow

1. Decompose epics into thin vertical stories.
2. Estimate size (prefer 1-8 points per story).
3. Plan sprint to match realistic capacity.
4. Generate stories with acceptance criteria and dependencies.
5. Update sprint status and hand off to developer.

Script Selection

• Story ID generation:

  bash scripts/generate-story-id.sh
  

• Velocity support:

  python3 scripts/calculate-velocity.py
  

• Burndown support:

  python3 scripts/sprint-burndown.py
  

Template Map

• templates/sprint-plan.template.md

• Why: sprint objective, scope, and sequencing.

• templates/user-story.template.md

• Why: story format with acceptance criteria.

• templates/sprint-status.template.yaml

• Why: machine-readable sprint tracking state.

Reference Map

• REFERENCE.md

• Must read first for sprint workflow guidance and story quality expectations.

• resources/story-sizing-guide.md

• Use to keep estimates consistent and avoid oversized stories.

Quality Gates

• sprint scope matches team capacity
• stories are independent and testable
• acceptance criteria and dependencies are explicit
• sprint status reflects planned work accurately
