SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? It automates a full development iteration without human interaction: turning an invocation intent into a specification, implementing it via a subagent, and running layered code reviews with triage, patching, and loopback until the work converges or halts with a clear status. ## Core Features & Use Cases - Intent routing and planning: Resolves intent from prompts, spec files, or folder+id story dispatch, compiles epic context from planning artifacts, and writes a ready-for-development spec from a template. - Subagent implementation and verification: Hands the spec to a context-free implementation subagent, stages a unified diff, runs verification commands, and audits I/O matrix test coverage. - Multi-layer review with triage: Runs blind-hunter, edge-case, verification-gap, and intent-alignment review layers, classifies findings into intent_gap, bad_spec, patch, or defer, and loops back through re-implementation when needed. - Use Case: Point it at a story in stories.yaml and it plans, implements, reviews, commits, and writes the run result into the story spec, halting with a blocking condition if anything cannot be resolved. ## Quick Start Invoke the bmad-build-auto skill with a description of the change you want implemented or a story id from your spec folder.

FAQPage Schema
How do I run an unattended development loop on a story?

Invoke the skill with a story id and spec folder, or with free-form intent. It routes through clarify, plan, implement, and review steps, writing results and status into the story's spec file when finished or blocked.

How does the automated code review work in this workflow?

Step 04 stages a unified diff and launches parallel review layers: blind hunter, edge-case hunter, verification-gap, and intent-alignment. Findings are verified, verdicted, grouped by root cause, and routed to patch, bad_spec loopback, intent_gap halt, or defer.

What happens when a review finds problems in the implementation?

Trivial fixes are patched by re-engaging the implementation subagent. Spec-level defects trigger a bad_spec loopback that amends the spec and re-derives the code, up to five iterations before halting as non-convergent.

Does this skill require version control and subagent support?

Yes. It captures a baseline revision, stages diffs, and commits reviewed changes, so git must be available and clean. Subagents are mandatory for implementation and review; without them the workflow halts with a blocked status.

When does the workflow halt instead of completing?

It halts with status blocked on unclear intent, intent gaps, dirty working trees, failed verification, missing specs, or exceeded review loop limits. Every halt writes the status and blocking condition into a result file.
