# Develop Story - Workflow Instructions ```xml The workflow execution engine is governed by: {project_root}/bmad/core/tasks/workflow.md You MUST have already loaded and processed: {installed_path}/workflow.yaml 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 If {{run_until_complete}} == true, run non-interactively: do not pause between steps unless a HALT condition is reached or explicit user approval is required for unapproved dependencies. 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) or a HALT condition is triggered. Do NOT schedule a "next session" or request review pauses unless a HALT condition applies. Only Step 6 decides completion. If {{story_path}} was explicitly provided and is valid → use it. Otherwise, attempt auto-discovery. Auto-discovery: Read {{story_dir}} from config (dev_story_location). If invalid/missing or contains no .md files, ASK user to provide either: (a) a story file path, or (b) a directory to scan. If a directory is provided, list story markdown files recursively under that directory matching pattern: "story-*.md". Sort candidates by last modified time (newest first) and take the top {{story_selection_limit}} items. Present the list with index, filename, and modified time. Ask: "Select a story (1-{{story_selection_limit}}) or enter a path:" Resolve the selected item into {{story_path}} Read the COMPLETE story file from {{story_path}} Parse sections: Story, Acceptance Criteria, Tasks/Subtasks (including subtasks), Dev Notes, Dev Agent Record, File List, Change Log, Status Identify the first incomplete task (unchecked [ ]) in Tasks/Subtasks; if subtasks exist, treat all subtasks as part of the selected task scope If no incomplete tasks found → "All tasks completed - proceed to completion sequence" and Continue If story file inaccessible → HALT: "Cannot develop story without access to story file" If task requirements ambiguous → ASK user to clarify; if unresolved, HALT: "Task requirements must be clear before implementation" Review acceptance criteria and dev notes for the selected task Plan implementation steps and edge cases; write down a brief plan in Dev Agent Record → Debug Log Implement the task COMPLETELY including all subtasks, following architecture patterns and coding standards in this repo Handle error conditions and edge cases appropriately If unapproved dependencies are needed → ASK user for approval before adding If 3 consecutive implementation failures occur → HALT and request guidance If required configuration is missing → HALT: "Cannot proceed without necessary configuration files" If {{run_until_complete}} == true → Do not stop after partial progress; continue iterating tasks until all ACs are satisfied or a HALT condition triggers Do NOT propose to pause for review, standups, or validation until Step 6 gates are satisfied Create unit tests for business logic and core functionality introduced/changed by the task Add integration tests for component interactions where applicable Include end-to-end tests for critical user flows if applicable Cover edge cases and error handling scenarios noted in the plan Determine how to run tests for this repo (infer or use {{run_tests_command}} if provided) Run all existing tests to ensure no regressions Run the new tests to verify implementation correctness Run linting and code quality checks if configured Validate implementation meets ALL story acceptance criteria; if ACs include quantitative thresholds (e.g., test pass rate), ensure they are met before marking complete If regression tests fail → STOP and fix before continuing If new tests fail → STOP and fix before continuing ONLY mark the task (and subtasks) checkbox with [x] if ALL tests pass and validation succeeds Update File List section with any new, modified, or deleted files (paths relative to repo root) Add completion notes to Dev Agent Record if significant changes were made (summarize intent, approach, and any follow-ups) Append a brief entry to Change Log describing the change Save the story file Determine if more incomplete tasks remain If more tasks remain → Next task If no tasks remain → Completion Verify ALL tasks and subtasks are marked [x] (re-scan the story document now) Run the full regression suite (do not skip) Confirm File List includes every changed file Execute story definition-of-done checklist, if the story includes one Update the story Status to: Ready for Review If any task is incomplete → Return to step 1 to complete remaining work (Do NOT finish with partial progress) If regression failures exist → STOP and resolve before completing If File List is incomplete → Update it before completing Optionally run the workflow validation task against the story using {project-root}/bmad/core/tasks/validate-workflow.md Prepare a concise summary in Dev Agent Record → Completion Notes Communicate that the story is Ready for Review ```
