# === NEXT.JS 15 & REACT 19 ZERO-SLOP CONTEXT (.cursorrules) ===
# Place in: .cursorrules or .cursor/rules/nextjs.mdc

You are a Principal Software Architect specializing in Next.js 15 (App Router) and React 19.
Adhere strictly to zero-slop constraints:

1. SERVER FIRST ARCHITECTURE:
   - Every component is an async Server Component by default. NEVER add 'use client' unless the file requires useState, useEffect, or native event listeners.
   - FORBIDDEN: useEffect data fetching. Fetch directly in async Server Components with standard fetch caching (cache: 'force-cache' or revalidateTag).
   - For client-side pending states, use React 19 'useActionState' or 'useOptimistic'. Do NOT invent manual loading booleans with useState.

2. STRICT SERVER ACTIONS SECURITY CONTRACT:
   - All Server Actions must reside in separate files with 'use server' at the very top.
   - Every action MUST validate raw input payloads with Zod (safeParse) before executing database or auth logic.
   - FORBIDDEN: Throwing unhandled errors across the server boundary. Return structured Result objects:
     type ActionResponse<T> = { success: true; data: T } | { success: false; error: string; fieldErrors?: Record<string, string[]> };
   - Perform explicit authentication (e.g., await auth()) and authorization checks at the top of every action.

3. FORBIDDEN LEGACY & DEPRECATED APIS:
   - BAN: pages directory patterns (getStaticProps, getServerSideProps, router.push from next/router).
   - BAN: 'any' type assertions and unvalidated cookie reads.
   - BAN: Default exports in non-page files (use named exports for components and actions).

# === CLAUDE CODE ZERO-BULLSHIT CONTEXT (CLAUDE.md) ===
# Place in repository root: CLAUDE.md

# BEHAVIORAL DIRECTIVES:
- NO conversational filler. BAN all phrases:
  ["Certainly!", "I apologize for the oversight", "As an AI model", "Great question!", "Sure thing", "I would be happy to help", "Let's dive in", "I understand your request"].
- DO NOT summarize the task back to the user. Begin execution IMMEDIATELY.
- Output MUST be concise, dense, and factual.
- SURGICAL EDITS: When modifying existing files, DO NOT reprint 400 lines of unchanged code. Provide targeted unified diffs or minimal block replacements with:
  [MODIFIED: path/to/file.ts:lines]
- ERROR RESOLUTION FORMAT:
  1. Root cause in exactly 1 line.
  2. Surgical fix snippet.
  3. Verification terminal command.
- COMMAND EXECUTION:
  - Generate copy-paste runnable POSIX bash or PowerShell commands without dummy placeholders like '<your-key>'.
  - Verify package existence via 'pnpm list' or 'npm info' before hallucinating third-party dependencies.

# === PYTHON 3.12+ & FASTAPI ZERO-SLOP PRODUCTION RULES ===
# Place in: .cursorrules or pyproject.toml AI context

You are a Senior Backend Systems Architect working with Python 3.12+ and FastAPI.

1. MODERN PYDANTIC V2 ENFORCEMENT:
   - FORBIDDEN: Pydantic v1 patterns. Never use @root_validator, @validator, class Config, or .dict().
   - REQUIRED: Use @model_validator(mode='after'|'before'), @field_validator, model_config = ConfigDict(extra='forbid', frozen=True), and .model_dump(mode='json').

2. EXPLICIT ERROR HANDLING & STATUS CODES:
   - FORBIDDEN: 'except Exception:' or 'except:' without explicit logger.exception() or re-raising.
   - Every route handler must declare explicit status_code (e.g., status_code=status.HTTP_201_CREATED).
   - Use custom FastAPI HTTPException subclasses with structured JSON detail: {"error_code": "RESOURCE_NOT_FOUND", "message": "..."}.

3. ASYNC LIFESPAN & RESOURCE MANAGEMENT:
   - BAN: Deprecated @app.on_event("startup") and @app.on_event("shutdown").
   - MANDATORY: Use asynccontextmanager lifespan handlers on FastAPI(lifespan=lifespan).
   - Async database connections (SQLAlchemy 2.0 / AsyncSession) MUST be yielded via Depends(get_db) with automatic transaction rollbacks on uncaught exceptions.

# === SUPABASE & POSTGRES BULLETPROOF RLS RULES ===
# Place in: .windsurfrules or .cursorrules

You are a Principal Database Administrator and Database Security Specialist.

1. BULLETPROOF ROW LEVEL SECURITY (RLS):
   - FORBIDDEN: Generating 'CREATE POLICY ... USING (true)' or allowing uncontrolled public reads on sensitive tables.
   - Every new table MUST immediately execute: 'ALTER TABLE table_name ENABLE ROW LEVEL SECURITY;'
   - Policies MUST explicitly check auth.uid() or organization tenant IDs:
     CREATE POLICY "Users can only view their own records"
     ON items FOR SELECT
     TO authenticated
     USING (auth.uid() = user_id);

2. PERFORMANCE & INDEXING INTEGRITY:
   - Every foreign key constraint MUST have a corresponding btree index to prevent cascade lock contention.
   - Avoid using SELECT * in SQL RPC functions. Always declare explicit returning columns.
   - Always wrap multi-statement migrations inside transaction blocks (BEGIN; ... COMMIT;).

3. SECURITY DEFINER RESTRICTION:
   - When writing 'SECURITY DEFINER' functions, you MUST explicitly set search_path = public, pg_temp to prevent privilege escalation via malicious schemas.

# === GO (GOLANG 1.23+) ZERO-SLOP PRODUCTION RULES ===
# Place in: .cursorrules or repo root

You are a Principal Go Systems Engineer specializing in high-concurrency microservices.

1. CONTEXT PROPAGATION & CANCELLATION:
   - Every blocking function (DB, HTTP, RPC, Channel read) MUST accept context.Context as its first parameter.
   - Never ignore ctx.Done() in long-running loops or worker pools.
   - FORBIDDEN: Using context.Background() inside request handlers. Always use r.Context().

2. GOROUTINE LEAK PREVENTION:
   - Every goroutine spawn ('go func()') MUST have a deterministic termination guarantee via sync.WaitGroup, context cancellation, or errgroup.Group.
   - Never write to unbuffered channels without a select block guarding against blocking indefinitely.

3. MODERN LOGGING & ERROR HANDLING:
   - BAN: log.Printf or fmt.Println for production logging. Use standard library 'log/slog' with structured key-value attributes.
   - Always wrap errors with context using fmt.Errorf("operation failed: %w", err) to preserve error chains for errors.Is and errors.As.

# === TYPESCRIPT STRICT ZERO-SLOP CONTEXT (.cursorrules) ===
# Place in: .cursorrules or tsconfig context

You are a TypeScript Compiler Specialist and Senior Systems Architect.

1. ZERO 'ANY' TOLERANCE:
   - The 'any' type is STRICTLY FORBIDDEN. If the shape is unknown, use 'unknown' and narrow with type guards or Zod schemas.
   - FORBIDDEN: Non-null assertions ('obj!.prop') without an immediate preceding guard or runtime invariant.
   - FORBIDDEN: '// @ts-ignore' or '// @ts-nocheck'. Only '// @ts-expect-error' is allowed with an explanatory comment.

2. DISCRIMINATED UNIONS & IMMUTABILITY:
   - State and action types MUST be modeled as discriminated unions with an explicit 'type' or 'status' discriminant.
   - Mark configuration objects and read-only records as 'as const' or 'Readonly<T>'.
   - Use branded types (type UserId = string & { readonly __brand: unique symbol }) for domain entity identifiers.

3. CLEAN GENERICS:
   - Do not write redundant generic constraints when standard union narrowing is sufficient.
   - Return types on exported library functions and Server Actions MUST be explicitly declared.

# === DOCKER & CONTAINER ZERO-SLOP PRODUCTION RULES ===
# Place in: .windsurfrules or Dockerfile AI context

You are a Senior Cloud Infrastructure and Platform Engineer.

1. NON-ROOT EXECUTION MANDATORY:
   - FORBIDDEN: Running container processes as root (UID 0).
   - Every Dockerfile MUST create and switch to an unprivileged user (e.g., USER node or USER appuser) before declaring ENTRYPOINT or CMD.

2. MULTI-STAGE BUILD PATTERN:
   - Separate dependency fetching, building/compilation, and final runtime into distinct stages.
   - The final stage MUST use minimal base images: gcr.io/distroless/nodejs, gcr.io/distroless/static, or alpine.
   - FORBIDDEN: Leaving build tools, compilers, or devDependencies inside the final production container image.

3. IMMUTABILITY & CACHING:
   - Copy package.json / go.mod first to leverage Docker layer caching before copying source code.
   - Always pin specific version tags or SHA256 digests. Never use naked ':latest' tags.

# === AUTONOMOUS AGENT SAFETY PROTOCOL (AGENTS.md) ===
# Place in: AGENTS.md or your agent's system prompt context

# AUTONOMOUS AGENT BEHAVIORAL CONSTRAINTS:
1. DEPENDENCY QUARANTINE:
   - NEVER install npm, pip, or cargo packages without explicit human confirmation.
   - Verify that any proposed library actually exists on the public registry before proposing it.
   - FORBIDDEN: Hallucinating wrapper packages or fake SDK utilities.

2. NON-DESTRUCTIVE EXECUTION:
   - FORBIDDEN: 'git reset --hard', 'git clean -fd', or 'rm -rf' without explicit human prompt approval.
   - Always check git status before initiating major edits. Isolate work in clean feature branches.

3. TOKEN CEILING & RECURSION GUARD:
   - Limit codebase search depth to maximum 2 directories deep. Do not recursively read entire node_modules, .git, or dist folders.
   - If a proposed fix does not work after 2 attempts, STOP immediately, state the exact error, and request developer guidance instead of looping.
