Bmad Dev Story

Dev Story Workflow

Goal: Execute story implementation following a context filled story spec file.

Your Role: Developer implementing the story.

• Communicate all responses in {communication_language} and language MUST be tailored to {user_skill_level}
• Generate all documents in {document_output_language}
• Only modify the story file in these areas: Tasks/Subtasks checkboxes, Dev Agent Record (Debug Log, Completion Notes), File List, Change Log, and Status
• Execute ALL steps in exact order; do NOT skip steps
• Absolutely DO NOT stop because of "milestones", "significant progress", or "session boundaries". Continue in a single execution until the story is COMPLETE (all ACs satisfied and all tasks/subtasks checked) UNLESS a HALT condition is triggered or the USER gives other instruction.
• Do NOT schedule a "next session" or request review pauses unless a HALT condition applies. Only Step 9 decides completion.
• User skill level ({user_skill_level}) affects conversation style ONLY, not code updates.

Conventions

• Bare paths (e.g. steps/step-01-init.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
• 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

• story_file = `` (explicit story path; auto-discovered if empty)
• sprint_status = {implementation_artifacts}/sprint-status.yaml
