# Correct Course - Sprint Change Management Workflow

**Goal:** Manage significant changes during sprint execution by analyzing impact across all project artifacts and producing a structured Sprint Change Proposal.

**Your Role:** You are a Developer navigating change management. Analyze the triggering issue, assess impact across PRD, epics, architecture, and UX artifacts, and produce an actionable Sprint Change Proposal with clear handoff.

## Conventions

- Bare paths (e.g. `checklist.md`) resolve from the skill root.
- `{skill-root}` resolves to this skill's installed directory (where `customize.toml` lives).
- `{project-root}`-prefixed paths resolve from the project working directory.
- `{skill-name}` resolves to the skill directory's basename.

## On Activation

### Step 1: Resolve the Workflow Block

Run: `python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow`

**If the script fails**, resolve the `workflow` block yourself by reading these three files in base → team → user order and applying the same structural merge rules as the resolver:

1. `{skill-root}/customize.toml` — defaults
2. `{project-root}/_bmad/custom/{skill-name}.toml` — team overrides
3. `{project-root}/_bmad/custom/{skill-name}.user.toml` — personal overrides

Any missing file is skipped. Scalars override, tables deep-merge, arrays of tables keyed by `code` or `id` replace matching entries and append new entries, and all other arrays append.

### Step 2: Execute Prepend Steps

Execute each entry in `{workflow.activation_steps_prepend}` in order before proceeding.

### Step 3: Load Persistent Facts

Treat every entry in `{workflow.persistent_facts}` as foundational context you carry for the rest of the workflow run. Entries prefixed `file:` are paths or globs under `{project-root}` — load the referenced contents as facts. All other entries are facts verbatim.

### Step 4: Load Config

Load config from `{project-root}/_bmad/bmm/config.yaml` and resolve:

- `project_name`, `user_name`
- `communication_language`, `document_output_language`
- `user_skill_level`
- `implementation_artifacts`
- `planning_artifacts`
- `project_knowledge`
- `date` as system-generated current datetime
- YOU MUST ALWAYS SPEAK OUTPUT in your Agent communication style with the config `{communication_language}`
- Language MUST be tailored to `{user_skill_level}`
- Generate all documents in `{document_output_language}`
- DOCUMENT OUTPUT: Updated epics, stories, or PRD sections. Clear, actionable changes. User skill level (`{user_skill_level}`) affects conversation style ONLY, not document updates.

### Step 5: Greet the User

Greet `{user_name}`, speaking in `{communication_language}`.

### Step 6: Execute Append Steps

Execute each entry in `{workflow.activation_steps_append}` in order.

Activation is complete. If `activation_steps_prepend` or `activation_steps_append` were non-empty, confirm every entry was executed in order before proceeding. Do not begin the main workflow until all activation steps have been completed.

## Paths

- `default_output_file` = `{planning_artifacts}/sprint-change-proposal-{date}.md`

## Input Files

| Input | Path | Load Strategy |
|-------|------|---------------|
| PRD | `{planning_artifacts}/*prd*.md` (whole) or `{planning_artifacts}/*prd*/*.md` (sharded) | FULL_LOAD |
| Epics | `{planning_artifacts}/*epic*.md` (whole) or `{planning_artifacts}/*epic*/*.md` (sharded) | FULL_LOAD |
| Architecture | `{planning_artifacts}/*architecture*.md` (whole) or `{planning_artifacts}/*architecture*/*.md` (sharded) | FULL_LOAD |
| UX Design | `{planning_artifacts}/*ux*.md` (whole) or `{planning_artifacts}/*ux*/*.md` (sharded) | FULL_LOAD |
| Spec | `{planning_artifacts}/*spec-*.md` (whole) | FULL_LOAD |
| Document Project | `{project_knowledge}/index.md` (sharded) | INDEX_GUIDED |

## Execution

### Document Discovery - Loading Project Artifacts

**Strategy**: Course correction needs broad project context to assess change impact accurately. Load all available planning artifacts.

**Discovery Process for FULL_LOAD documents (PRD, Epics, Architecture, UX Design, Spec):**

1. **Search for whole document first** - Look for files matching the whole-document pattern (e.g., `*prd*.md`, `*epic*.md`, `*architecture*.md`, `*ux*.md`, `*spec-*.md`)
2. **Check for sharded version** - If whole document not found, look for a directory with `index.md` (e.g., `prd/index.md`, `epics/index.md`)
3. **If sharded version found**:
   - Read `index.md` to understand the document structure
   - Read ALL section files listed in the index
   - Process the combined content as a single document
4. **Priority**: If both whole and sharded versions exist, use the whole document

**Discovery Process for INDEX_GUIDED documents (Document Project):**

1. **Search for index file** - Look for `{project_knowledge}/index.md`
2. **If found**: Read the index to understand available documentation sections
3. **Selectively load sections** based on relevance to the change being analyzed — do NOT load everything, only sections that relate to the impacted areas
4. **This document is optional** — skip if `{project_knowledge}` does not exist (greenfield projects)

**Fuzzy matching**: Be flexible with document names — users may use variations like `prd.md`, `bmm-prd.md`, `product-requirements.md`, etc.

**Missing documents**: Not all documents may exist. PRD and Epics are essential; Architecture, UX Design, Spec, and Document Project are loaded if available. HALT if PRD or Epics cannot be found.

  <action>Ask user for mode preference:</action>
    - **Incremental** (recommended): Refine each edit collaboratively

<action>For Story changes:</action>

- Show old → new text format
- Include story ID and section being modified

- Example format:

  ```
  Story: [STORY-123] User Authentication
  Section: Acceptance Criteria

  - User can log in with email/password
  - User can enable 2FA via authenticator
