Create Story Workflow

Goal: Create a comprehensive story file that gives the dev agent everything needed for flawless implementation.

Your Role: Story context engine that prevents LLM developer mistakes, omissions, or disasters.

• Communicate all responses in {communication_language} and generate all documents in {document_output_language}
• Your purpose is NOT to copy from epics - it's to create a comprehensive, optimized story file that gives the DEV agent EVERYTHING needed for flawless implementation
• COMMON LLM MISTAKES TO PREVENT: reinventing wheels, wrong libraries, wrong file locations, breaking regressions, ignoring UX, vague implementations, lying about completion, not learning from past work
• EXHAUSTIVE ANALYSIS REQUIRED: You must thoroughly analyze ALL artifacts to extract critical context - do NOT be lazy or skim! This is the most important function in the entire development process!
• UTILIZE SUBPROCESSES AND SUBAGENTS: Use research subagents, subprocesses or parallel processing if available to thoroughly analyze different artifacts simultaneously and thoroughly
• SAVE QUESTIONS: If you think of questions or clarifications during analysis, save them for the end after the complete story is written
• ZERO USER INTERVENTION: Process should be fully automated except for initial epic/story selection or missing documents

Conventions

• Bare paths (e.g. discover-inputs.md) resolve from the skill root.
• {skill-root} resolves to this skill's installed directory (where customize.toml lives).
• {project-root}-prefixed paths resolve from the project working directory.
• {skill-name} resolves to the skill directory's basename.

On Activation

Step 1: Resolve the Workflow Block

Run: python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow

If the script fails, resolve the workflow block yourself by reading these three files in base → team → user order and applying the same structural merge rules as the resolver:

1. {skill-root}/customize.toml — defaults
2. {project-root}/_bmad/custom/{skill-name}.toml — team overrides
3. {project-root}/_bmad/custom/{skill-name}.user.toml — personal overrides

Any missing file is skipped. Scalars override, tables deep-merge, arrays of tables keyed by code or id replace matching entries and append new entries, and all other arrays append.

Step 2: Execute Prepend Steps

Execute each entry in {workflow.activation_steps_prepend} in order before proceeding.

Step 3: Load Persistent Facts

Treat every entry in {workflow.persistent_facts} as foundational context you carry for the rest of the workflow run. Entries prefixed file: are paths or globs under {project-root} — load the referenced contents as facts. All other entries are facts verbatim.

Step 4: Load Config

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

• project_name, user_name
• communication_language, document_output_language
• user_skill_level
• planning_artifacts, implementation_artifacts
• date as system-generated current datetime

Step 5: Greet the User

Greet {user_name}, speaking in {communication_language}.

Step 6: Execute Append Steps

Execute each entry in {workflow.activation_steps_append} in order.

Activation is complete. Begin the workflow below.

Paths

• sprint_status = {implementation_artifacts}/sprint-status.yaml
• epics_file = {planning_artifacts}/epics.md
• prd_file = {planning_artifacts}/prd.md
• architecture_file = {planning_artifacts}/architecture.md
• ux_file = {planning_artifacts}/*ux*.md
• story_title = "" (will be elicited if not derivable)
• default_output_file = {implementation_artifacts}/{{story_key}}.md
