- **Communication Language**: ${configVars.communication_language || '{{communication_language}}'}
- **Document Output Language**: ${configVars.document_output_language || '{{document_output_language}}'}
- **User Skill Level**: ${configVars.user_skill_level || '{{user_skill_level}}'}
- **Output Folder**: ${configVars.output_folder || '{{output_folder}}'}
- **Planning Artifacts**: ${configVars.planning_artifacts || '{{planning_artifacts}}'}
- **Implementation Artifacts**: ${configVars.implementation_artifacts || '{{implementation_artifacts}}'}
- **Project Knowledge**: ${configVars.project_knowledge || '{{project_knowledge}}'}
## BMAD Runtime Structure
- **Agent definitions**: \`${bmad}/bmm/agents/\` (BMM module) and \`${bmad}/core/agents/\` (core)
- **Workflow definitions**: \`${bmad}/bmm/workflows/\` (organized by phase)
- **Core tasks**: \`${bmad}/core/tasks/\` (help, editorial review, indexing, sharding, adversarial review)
- **Core workflows**: \`${bmad}/core/workflows/\` (brainstorming, party-mode, advanced-elicitation)
- **Workflow engine**: \`${bmad}/core/tasks/workflow.xml\` (executes YAML-based workflows)
- **Module configuration**: \`${bmad}/bmm/config.yaml\`
- **Core configuration**: \`${bmad}/core/config.yaml\`
- **Agent manifest**: \`${bmad}/_config/agent-manifest.csv\`
- **Workflow manifest**: \`${bmad}/_config/workflow-manifest.csv\`
- **Help manifest**: \`${bmad}/_config/bmad-help.csv\`
- **Agent memory**: \`${bmad}/_memory/\`
## Key Conventions
- Always load \`${bmad}/bmm/config.yaml\` before any agent activation or workflow execution
- Store all config fields as session variables: \`{user_name}\`, \`{communication_language}\`, \`{output_folder}\`, \`{planning_artifacts}\`, \`{implementation_artifacts}\`, \`{project_knowledge}\`
- MD-based workflows execute directly — load and follow the \`.md\` file
- YAML-based workflows require the workflow engine — load \`workflow.xml\` first, then pass the \`.yaml\` config
- Follow step-based workflow execution: load steps JIT, never multiple at once
- Save outputs after EACH step when using the workflow engine
- The \`{project-root}\` variable resolves to the workspace root at runtime
