Step One-Shot: Implement, Review, Present

RULES

Language — Speak in {{.communication_language}}. Write any file output in {{.document_output_language}}.
NEVER auto-push.
All review subagents must run at the same model capability as the current session.
Run subagents synchronously: launch them together, then wait for all results before continuing.

INSTRUCTIONS

Implement

Follow [[bmad-snapshot:sync-sprint-status.md]] with target_status = in-progress.

Implement the clarified intent directly.

Review

Execute these review layers in parallel wherever their execution methods allow. After substituting runtime placeholders, when an instruction launches a reviewer subagent, launch that child with the prompt text; do not load the reviewer instruction file yourself. For any other customized instruction, execute it as written:

{workflow.oneshot_review_layers}

If a layer's instruction requires subagents and none are available, for each such layer write under {{.implementation_artifacts}} the exact child prompt from that layer's instruction after placeholder substitution (not a path-only pointer), then HALT. Ask the human to run each in a separate session and paste back the findings.

Classify

Deduplicate all review findings. Three categories only:

patch — trivially fixable. Auto-fix immediately.
defer — pre-existing issue not caused by this change. Append one new entry to {{.implementation_artifacts}}/deferred-work.md using this format. Do not modify existing entries or look for duplicates.
markdown
```
- source_spec: `{spec_file}`
  summary: <one sentence>
  evidence: <why this is real>
```
reject — noise. Drop silently.

If a finding is caused by this change but too significant for a trivial patch, HALT and present it to the human for decision before proceeding.

Generate Spec Trace

Set title = a concise title derived from the clarified intent.

Write {spec_file} using [[bmad-snapshot:spec-template.md]]. Fill only these sections — delete all others:

Frontmatter — set title: '{title}', type, created, status: 'done'. Add route: 'one-shot'.
Title and Intent — # {title} heading and ## Intent with Problem and Approach lines. Reuse the summary you already generated for the terminal.
Suggested Review Order — append after Intent. Build using the same convention as [[bmad-snapshot:step-05-present.md]] § "Generate Suggested Review Order" (spec-file-relative links, concern-based ordering, ultra-concise framing).

Follow [[bmad-snapshot:sync-sprint-status.md]] with target_status = review.

Commit

If version control is available and the tree is dirty, create a local commit with a conventional message derived from the intent. If VCS is unavailable, skip.

Present

{workflow.open_spec}

Display a summary in conversation output, including:

The commit hash (if one was created).
List of files changed with one-line descriptions. Any file paths shown in conversation/terminal output must use CWD-relative format (no leading /) with :line notation (e.g., src/path/file.ts:42) for terminal clickability — this differs from spec-file links which use spec-file-relative paths.
Review findings breakdown: patches applied, items deferred, items rejected. If all findings were rejected, say so.

Offer to push and/or create a pull request.

HALT and wait for human input.

Workflow complete.

On Complete

If anything appears below, follow it as the final terminal instruction before exiting; otherwise exit normally.

{workflow.on_complete}
