Bmad Dev Auto

Dev Auto Workflow

Goal: Turn intent into a hardened, reviewable artifact, without human interaction.

CRITICAL: If a step says "read fully and follow step-XX", you read and follow step-XX. No exceptions.

HALT

To HALT with a final status and optional blocking condition:

1. Folder+id dispatch ({spec_folder} and {story_id} are set): the write-back always lands at the id-keyed story spec. The {implementation_artifacts} fallback in step 2 below is never used in this mode, even for halts before planning starts.
   • If {spec_file} is still empty, resolve it now:
     • Entry not resolved (stories.yaml is missing/unparseable, or {story_id} has no matching entry): use the fixed slug segment unresolved: {spec_file} = {spec_folder}/stories/{story_id}-unresolved.md.
     • Ambiguous on-disk match (the halt is ambiguous story file match — more than one file already matches {spec_folder}/stories/{story_id}-*.md): use the fixed slug segment ambiguous instead of deriving from the title, so the write-back neither creates a third title-derived candidate nor risks silently landing on one of the existing ambiguous files: {spec_file} = {spec_folder}/stories/{story_id}-ambiguous.md.
     • Otherwise (the entry was resolved and no ambiguous on-disk match exists): derive {spec_file} = {spec_folder}/stories/{story_id}-{slug}.md, where {slug} is a kebab-case slug from title (and description if needed) with no {story_id} prefix — the same derivation step-01's Route uses.
   • If {spec_file} exists on disk, update status in frontmatter and append missing result details under ## Auto Run Result.
   • If it does not exist, create it as a skeletal story spec:

     ---
     status: <final status>
     ---
     
     # <entry title, or "Story {story_id}" if the entry could not be resolved or the on-disk match was ambiguous>
     
     ## Auto Run Result
     
     Status: <final status>
     Blocking condition: <blocking condition, if any>

2. Otherwise:
   • If {spec_file} is known and exists, update status in frontmatter and append missing result details under ## Auto Run Result.
   • If {spec_file} is unknown or missing, create {implementation_artifacts}/bmad-dev-auto-result-<slug-or-timestamp>.md with:

     ---
     status: <final status>
     ---
     
     # BMad Dev Auto Result
     
     Status: <final status>
     Blocking condition: <blocking condition, if any>

3. Run: python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow.on_complete
4. If the resolved workflow.on_complete is non-empty, follow it as the final instruction before exiting.
5. Stop the workflow.

Subagents

Using subagents when instructed is mandatory. If you cannot, HALT with status blocked and blocking condition no subagents.

Invoke every subagent synchronously: launch it, wait for it to return within the same turn, then continue with its result. When a step says to run subagents "in parallel" (e.g. the reviewers), that means several blocking calls awaited together in one turn — not detached execution. Never run a subagent in the background / detached / async (e.g. run_in_background: true), and never end your turn to "await a completion notification." This workflow runs unattended: there is no event loop to resume a yielded turn, so a backgrounded subagent never hands control back and the run stalls. The only sanctioned way to end a turn is the HALT protocol above with an explicit terminal status.
