description	Product planning skill for BMAD. Use for bmad:prd, bmad:tech-spec, and bmad:prioritize to convert discovery into executable requirements.

BMAD Product Manager

Trigger Intents

• bmad:prd
• bmad:tech-spec
• bmad:prioritize

Workflow Variants

1. prd

• Default for level 2-4 initiatives and multi-epic scope.

2. tech-spec

• Default for level 0-1 changes or tightly scoped features.

3. prioritize

• Use to rank backlog items and resolve scope pressure.

Decision rule:

• Level 0-1 -> start with tech-spec
• Level 2-4 -> start with prd

Inputs

• discovery artifacts from analyst (product-brief, research)
• bmad/project.yaml project level and constraints
• known business goals and delivery timeline

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 Given, when, then in English as notation tokens and format them in bold (**Given**, **when**, **then**)
• localize field values such as Compliance, Load Profile, and Measurement Method
• Keep code snippets, CLI commands, file paths, and identifiers in their original technical form.

Mandatory Reference Load

Before executing prd, tech-spec, or prioritize, read REFERENCE.md first. Treat REFERENCE.md as required context for requirement quality and handoff discipline.

Output Contract

• prd -> docs/bmad/prd.md
• tech-spec -> docs/bmad/tech-spec.md
• prioritize -> docs/bmad/prioritization.md

Core Workflow

1. Select planning artifact by project level and uncertainty.
2. Define functional and non-functional requirements.
3. Break requirements into epics and candidate stories.
4. Attach acceptance criteria and priorities.
5. Provide architecture-ready handoff notes.

Script Selection

• Prioritization helper:

  python3 scripts/prioritize.py
  

• PRD quality check:

  bash scripts/validate-prd.sh docs/bmad/prd.md
  

Template Map

• templates/prd.template.md

• Why: complete requirements structure for medium/large scope.

• templates/tech-spec.template.md

• Why: compact requirements for low-complexity scope.

Reference Map

• REFERENCE.md

• Must read first for requirement quality rules, workflow guidance, and handoff practices.

• resources/prioritization-frameworks.md

• Use when selecting MoSCoW, RICE, or alternative prioritization methods.

Quality Gates

• requirements are specific, testable, and unambiguous
• FR/NFR coverage is explicit
• acceptance criteria exist for planned stories
• priorities and trade-offs are justified
• next intent is explicit (bmad:architecture or bmad:sprint-plan)
