This executes:\n\n- **N+1 static analysis** — scans Python files for ORM query patterns inside loops, raw SQL in loops, string-formatted SQL, and related-field access without eager loading.\n- **Endpoint profiler** — if `--base-url` and `--paths` are given, times each endpoint (3 warmup + 5 measured, reports p50\u002Fp95\u002Fp99). Flags endpoints >200ms (MEDIUM), >500ms (HIGH), >1000ms (CRITICAL).\n\nThe tool writes `.reports\u002Fspine-perf-\u003Cts>.json` and exits 2 on CRITICAL\u002FHIGH findings (CI gate).\n\nReview the JSON report to seed the investigation in Steps 1-7 below.\n\n### Step 1: Detect Environment\n\n```bash\nls -a\n```\n\nIdentify the framework and ORM: package.json (Express\u002FFastify + Prisma\u002FTypeORM\u002FDrizzle\u002FSequelize), pyproject.toml (FastAPI\u002FDjango + SQLAlchemy\u002FDjango ORM), go.mod (GORM, sqlx), Gemfile (Rails + ActiveRecord). Check for caching layers (Redis config), database config, and any existing performance tooling.\n\n### Step 1: Read the Code Path\n\nRead the specific code path the user is asking about. If they haven't specified, ask which endpoint or operation is slow. Trace the full request lifecycle:\n\n- Route handler \u002F controller\n- Middleware that runs on this path\n- Service \u002F business logic layer\n- Database queries (ORM calls, raw queries)\n- External API calls\n- Response serialization\n\n### Step 2: Identify N+1 Queries\n\nLook for patterns where:\n\n- A list is fetched, then each item triggers an additional query (classic N+1)\n- Associations\u002Frelations are accessed in a loop without eager loading\n- ORM `.map()` \u002F `.forEach()` \u002F list comprehensions trigger lazy-loaded queries\n\nFor each N+1 found: explain the query pattern, show the fix (eager loading, join, subquery), and estimate the improvement (e.g., \"N+1 with 100 items = 101 queries -> 1 query\").\n\n### Step 3: Check for Missing Indexes\n\nReview the database queries in the code path and check:\n\n- Are WHERE clause columns indexed?\n- Are JOIN columns indexed?\n- Are ORDER BY columns indexed?\n- Are there composite indexes for multi-column queries?\n\nCheck migration files or schema definitions for existing indexes. Suggest specific indexes to add.\n\n### Step 4: Identify Synchronous Bottlenecks\n\nFlag operations that block the request unnecessarily:\n\n- Synchronous external API calls that could be parallelized\n- Sequential database queries that are independent and could run concurrently\n- File I\u002FO or computation on the request path that could be offloaded\n- Missing connection pooling causing connection creation overhead\n\n### Step 5: Check Caching Opportunities\n\nIdentify data that could be cached:\n\n- Frequently read, rarely written data (user profiles, config, feature flags)\n- Expensive computations or aggregations\n- External API responses with acceptable staleness\n- Database query results for hot paths\n\nFor each: suggest cache strategy (in-memory, Redis, HTTP cache headers), TTL, and invalidation approach.\n\n### Step 6: Check Serialization Overhead\n\nFlag:\n\n- Over-fetching from database (SELECT \\* when only 3 fields are needed)\n- Serializing large nested objects when the client needs a subset\n- Missing field selection or GraphQL-style projection\n- Large payloads that could use pagination or streaming\n\n### Step 7: Present the Report\n\nFormat as:\n\n```\n## Performance Analysis: [endpoint\u002Foperation]\n\n### Issues Found\n\n#### 1.
