Do NOT ask the user questions.</p>\n<h1>============================================================\nTARGET: $ARGUMENTS</h1>\n<ul>\n<li>If $ARGUMENTS contains a feature description, use it as the basis for the spec.</li>\n<li>If $ARGUMENTS contains an image path, read the image to extract the design or spec to implement.</li>\n<li>If $ARGUMENTS contains \"BE:\" or \"FE:\", use that as the story type prefix.</li>\n<li>If $ARGUMENTS contains output from <code>/mvp</code> analysis, use the story candidates and feature breakdown as the basis. Do not re-analyze the application — trust the MVP output.</li>\n<li>If $ARGUMENTS is empty, check for recent <code>/mvp</code> output in the conversation context. If none, report that a feature description or story input is required.</li>\n</ul>\n<h1>============================================================\nPHASE 1: DETERMINE STORY TYPE</h1>\n<p>Based on the input, determine whether this is a backend or frontend story:</p>\n<ul>\n<li>If the work involves API endpoints, database changes, business logic, or server-side processing: prefix with \"BE:\"</li>\n<li>If the work involves UI components, pages, user interactions, or client-side logic: prefix with \"FE:\"</li>\n<li>If the user explicitly states the type, use that.</li>\n<li>If both are needed, generate two separate stories (one BE, one FE).</li>\n</ul>\n<p>TITLE FORMAT:</p>\n<p>The title must start with \"BE:\" or \"FE:\" followed by a short feature name.\nExamples:</p>\n<ul>\n<li>BE: Spin Wheel Gamification</li>\n<li>FE: Swag Collection Browse Page\nKeep it concise — no more than 8 words after the prefix.</li>\n</ul>\n<h1>============================================================\nPHASE 2: GENERATE SPEC</h1>\n<h3>Description</h3>\n<p>One concise paragraph (2-4 sentences max) that explains:</p>\n<ul>\n<li>What is being built</li>\n<li>How users interact with it</li>\n<li>The high-level outcome</li>\n</ul>\n<p>No filler language. No implementation details. Just the what and why.</p>\n<h3>Acceptance Criteria</h3>\n<p>Organize criteria into logical groups. Each group has:</p>\n<ul>\n<li>A bold category header as a top-level bullet: <strong>Category Name:</strong></li>\n<li>Sub-bullets under each category with specific, testable requirements</li>\n</ul>\n<p>Format exactly like this:</p>\n<ul>\n<li><p><strong>Category Name:</strong></p>\n<ul>\n<li>Requirement sentence.</li>\n<li>Another requirement sentence.</li>\n</ul>\n</li>\n<li><p><strong>Another Category:</strong></p>\n<ul>\n<li>Requirement sentence.</li>\n</ul>\n</li>\n</ul>\n<p>CATEGORY RULES:</p>\n<ul>\n<li>Group related requirements together under a descriptive bold header.</li>\n<li>Every requirement must be a standalone, testable sentence.</li>\n<li>Include validation behavior, failure behavior, and edge cases.</li>\n<li>Include idempotency rules when applicable.</li>\n</ul>\n<p>ROUTES CATEGORY (for BE stories):</p>\n<ul>\n<li>Always include a <strong>Routes:</strong> category if the story involves API endpoints.</li>\n<li>Start with authentication requirements (e.g., \"All endpoints require user authentication.\").</li>\n<li>List each endpoint with: who calls it, the method and full path in inline code, and what it does.</li>\n<li>Format: FE can call <code>METHOD /service-name/path</code> to <a href=\"#description\">description</a>.</li>\n<li>Include request behavior, response behavior, and error behavior.</li>\n</ul>\n<p>Example:</p>\n<ul>\n<li><strong>Routes:</strong>\n<ul>\n<li>All endpoints require user authentication.</li>\n<li>FE can call <code>GET /vendor-service/spin-wheel/slots</code> to receive the wheel configuration for the active game resolved for their organization (org-specific game first, falls back to global).</li>\n<li>FE can call <code>POST /vendor-service/spin-wheel/spin</code> to consume 1 spin; the backend randomly selects a slot and returns the entries value and slot index.</li>\n</ul>\n</li>\n</ul>\n<p>UI BEHAVIOR CATEGORY (for FE stories):</p>\n<ul>\n<li>Include a <strong>UI Behavior:</strong> category for frontend stories.</li>\n<li>Describe component behavior, states (loading, empty, error, success), and interactions.</li>\n<li>Reference specific API endpoints the FE will consume (use inline code for paths).</li>\n</ul>\n<p>GAME RULES / INFO CATEGORY:</p>\n<ul>\n<li>Include a <strong>Game Rules/Info:</strong> category when there are lifecycle rules, resolution logic, or constraints.</li>\n<li>Define lifecycle states (draft, active, inactive).</li>\n<li>Define constraints (e.g., only one active game per type per organization).</li>\n<li>Define aggregation logic if applicable.</li>\n</ul>\n<h1>============================================================\nPHASE 3: GENERATE DEV NOTES</h1>\n<h3>Dev Notes</h3>\n<p>Technical implementation guidance for the developer.</p>\n<p>FOR BACKEND STORIES:</p>\n<p><strong>Schema</strong>: State the schema name in bold.\nExample: New Schema – <strong>gamification</strong></p>\n<p><strong>Tables</strong>: List each table with columns in this format:</p>\n<p>Tables:</p>\n<p><strong>table_name</strong></p>\n<ul>\n<li>column_name (TYPE, modifiers) — description</li>\n<li>column_name (TYPE, modifiers) — description</li>\n<li>Indexes: description of indexes</li>\n<li>Foreign keys: description of foreign keys</li>\n</ul>\n<p>Additional dev notes sections as needed:</p>\n<ul>\n<li><strong>Game Resolution Logic</strong>: Exact resolution conditions, fallback order, behavior when no active game exists.</li>\n<li><strong>Hooks into existing code</strong>: Exact services and methods that trigger behavior, whether blocking or fire-and-forget, idempotency mechanism.</li>\n<li><strong>Concurrency Protection</strong>: Database-level protection, advisory locks or transactional protection, how double-spending is prevented.</li>\n</ul>\n<p>FOR FRONTEND STORIES:</p>\n<ul>\n<li><strong>Components</strong>: List new components to create and existing ones to modify.</li>\n<li><strong>State Management</strong>: Describe what state is needed and where it lives.</li>\n<li><strong>API Integration</strong>: List endpoints to consume with request/response shapes.</li>\n<li><strong>Routing</strong>: New routes or route changes needed.</li>\n</ul>\n<h1>============================================================\nPHASE 4: VERIFY SPEC COMPLETENESS</h1>\n<p>Self-check the generated spec:</p>\n<ol>\n<li>Every acceptance criterion is testable (no vague language).</li>\n<li>Every API route includes method, full path, and behavior description.</li>\n<li>Every table includes column types and modifiers.</li>\n<li>No placeholders or \"TBD\" markers remain.</li>\n<li>The description is 2-4 sentences, no more.</li>\n<li>The title follows the BE:/FE: format with 8 words or fewer after the prefix.</li>\n</ol>\n<h1>============================================================\nSELF-HEALING VALIDATION (max 2 iterations)</h1>\n<p>After producing output, validate data quality and completeness:</p>\n<ol>\n<li>Verify all output sections have substantive content (not just headers).</li>\n<li>Verify every finding references a specific file, code location, or data point.</li>\n<li>Verify recommendations are actionable and evidence-based.</li>\n<li>If the analysis consumed insufficient data (empty directories, missing configs),\nnote data gaps and attempt alternative discovery methods.</li>\n</ol>\n<p>IF VALIDATION FAILS:</p>\n<ul>\n<li>Identify which sections are incomplete or lack evidence</li>\n<li>Re-analyze the deficient areas with expanded search patterns</li>\n<li>Repeat up to 2 iterations</li>\n</ul>\n<p>IF STILL INCOMPLETE after 2 iterations:</p>\n<ul>\n<li>Flag specific gaps in the output</li>\n<li>Note what data would be needed to complete the analysis</li>\n</ul>\n<h1>============================================================\nOUTPUT</h1>\n<h2>Spec Generated</h2>\n<table>\n<thead>\n<tr>\n<th>Field</th>\n<th>Value</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td>Title</td>\n<td>BE:/FE: [Story Title]</td>\n</tr>\n<tr>\n<td>Type</td>\n<td>Backend / Frontend</td>\n</tr>\n<tr>\n<td>Acceptance criteria groups</td>\n<td>N</td>\n</tr>\n<tr>\n<td>Total criteria</td>\n<td>N</td>\n</tr>\n<tr>\n<td>API routes defined</td>\n<td>N</td>\n</tr>\n<tr>\n<td>Database tables defined</td>\n<td>N</td>\n</tr>\n<tr>\n<td>Estimated complexity</td>\n<td>Low / Medium / High</td>\n</tr>\n</tbody>\n</table>\n<p>[Full spec content follows in the sections above]</p>\n<h1>============================================================\nSTRICT RULES</h1>\n<ul>\n<li>Match this format exactly.
