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.
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.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:
{skill-root}/customize.toml — defaults{project-root}/_bmad/custom/{skill-name}.toml — team overrides{project-root}/_bmad/custom/{skill-name}.user.toml — personal overridesAny 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.
Execute each entry in {workflow.activation_steps_prepend} in order before proceeding.
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.
Load config from {project-root}/_bmad/bmm/config.yaml and resolve:

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

**Story Details:**
- Story ID: {{story_id}}
- Story Key: {{story_key}}
- File: {{story_file}}
- Status: ready-for-dev
**Next Steps:**
1. Review the comprehensive story in {{story_file}}
2. Run dev agents `dev-story` for optimized implementation
3. Run `code-review` when complete (auto-marks done)
4. Optional: If Test Architect module installed, run `/bmad:tea:automate` after `dev-story` to generate guardrail tests
**The developer now has everything needed for flawless implementation!**
