Implement fixes based on QA results (gate and assessments) for a specific story. This task is for the Dev agent to systematically consume QA outputs and apply code/test changes while only updating allowed sections in the story file.
## Purpose
- Read QA outputs for a story (gate YAML + assessment markdowns)
- Create a prioritized, deterministic fix plan
- Apply code and test changes to close gaps and address issues
- Update only the allowed story sections for the Dev agent
## Inputs
```yaml
required:
- story_id: '{epic}.{story}' # e.g., "2.2"
- qa_root: from `bmad-core/core-config.yaml` key `qa.qaLocation` (e.g., `docs/project/qa`)
- story_root: from `bmad-core/core-config.yaml` key `devStoryLocation` (e.g., `docs/project/stories`)
optional:
- story_title: '{title}' # derive from story H1 if missing
- story_slug: '{slug}' # derive from title (lowercase, hyphenated) if missing
- Keep changes minimal and targeted; follow project architecture and TS/Deno rules
### 3) Apply Changes
- Implement code fixes per plan
- Add missing tests to close coverage gaps (unit first; integration where required by AC)
- Keep imports centralized via `deps.ts` (see `docs/project/typescript-rules.md`)
- Follow DI boundaries in `src/core/di.ts` and existing patterns
### 4) Validate
- Run `deno lint` and fix issues
- Run `deno test -A` until all tests pass
- Iterate until clean
### 5) Update Story (Allowed Sections ONLY)
CRITICAL: Dev agent is ONLY authorized to update these sections of the story file. Do not modify any other sections (e.g., QA Results, Story, Acceptance Criteria, Dev Notes, Testing):
