name: rbac-permissions-architect description: Use this skill when architecting new features within the RBAC modular permissions system. Guides architects through workspace design, feature definition, permission mapping, and role hierarchy. Critical for understanding Owner/Super Admin special roles, feature independence, and multi-tenant context isolation. Invoke when creating PRDs that involve permissions, workspaces, features, or role-based access control.

RBAC Permissions Architect

Purpose

This skill enables the Architect Agent to design features that correctly integrate with the project's RBAC modular permissions system defined in concepto-base.md. It provides the necessary understanding of workspaces, features, permissions, and special roles to create compliant PRDs and entity designs.

When to Use This Skill

Use this skill when:

Creating a new feature that involves permissions or access control
Designing features that operate within workspaces (organizations or projects)
Defining resources and permissions for a new feature module
Creating entities that need to respect workspace boundaries
Architecting features that interact with Owner/Super Admin roles
Any PRD that mentions: permissions, roles, access, workspaces, features, RLS

Core Understanding Required

Before architecting any feature, understand these immutable principles:

1. The Three Pillars (Independent but Interconnected)

WORKSPACES (Containers)
    ↓
FEATURES (Modules)
    ↓
RBAC (Access Control)

Workspaces: Organizations (root) and Projects (children)
Features: Activatable modules with their own resources/permissions
RBAC: Granular permissions grouped into roles

2. Critical Rules

NO inheritance: Features and permissions DO NOT inherit between workspaces
Contextual permissions: Permissions only apply in the workspace where assigned
Special roles: Owner and Super Admin transcend normal permission rules
Mandatory feature: permissions-management is always active
Independence: Each workspace activates features explicitly

Architect Workflow for RBAC-Aware Features

Phase 1: Feature Scope Definition

Questions to answer:

Workspace scope: Does this feature apply to organizations, projects, or both?
Resource identification: What entities will users interact with?
Permission granularity: What actions can users perform on each resource?
Role requirements: Are there default roles needed for this feature?
Special role interaction: How do Owner/Super Admin interact with this feature?

Reference files to consult:

Basic concepts: CONCEPTS.md - Workspace, Feature, Resource, Permission, Role definitions
Workspace architecture: WORKSPACES.md - Organization vs Project behavior

Phase 2: Permission Matrix Design

Steps:

List all resources in your feature (e.g., boards, cards, comments)
Define CRUD+ actions for each resource (create, read, update, delete, custom actions)
Map to permission format: {resource}.{action} (e.g., boards.create, cards.move)
Consider visibility: Which permission grants UI visibility? (usually .read)
Document restrictions: What can Owner/Super Admin do that normal users cannot?

Example permission matrix:

Feature: kanban

Resources:
├─ boards
├─ cards
└─ card_comments

Permissions:
├─ boards.create
├─ boards.read      ← Grants visibility of Kanban in UI
├─ boards.update
├─ boards.delete
├─ cards.create
├─ cards.read
├─ cards.update
├─ cards.delete
├─ cards.move       ← Custom action
├─ card_comments.create
└─ card_comments.delete

Reference file to consult:

Permission system: PERMISSIONS.md - Granular permissions, roles, verification flows

Phase 2.5: CASL Ability Definition

⚡ NEW: Authorization Layer Integration

After defining the permission matrix, specify how CASL (the project's authorization library) will implement these permissions.

Questions to answer:

Subject mapping: What are the CASL subjects for each resource?
Action alignment: Do CASL actions match permission actions perfectly?
Conditional rules: Are there context-dependent rules (e.g., "own resources only")?
Type safety: How do we enforce TypeScript types for subjects and actions?

CASL Subjects (PascalCase, Singular):

Map each database resource to a CASL subject:

// Database resources → CASL subjects
'boards'        → 'Board'
'cards'         → 'Card'
'card_comments' → 'Comment'

Rules:

Use PascalCase for subjects (CASL convention)
Use singular form (Board, not Boards)
One resource = one subject (1:1 mapping)

CASL Actions:

Standard actions align with permissions:

'create' → boards.create
'read'   → boards.read
'update' → boards.update
'delete' → boards.delete

Custom actions:

'move'   → cards.move
'assign' → cards.assign

Ability Builder Template:

Include this in your PRD's entities.ts:

// ===== CASL Integration =====
import { AbilityBuilder, createMongoAbility, MongoAbility } from '@casl/ability';

// Define CASL types
type Subjects = 'Board' | 'Card' | 'Comment' | 'all';
type Actions = 'create' | 'read' | 'update' | 'delete' | 'move' | 'manage';
export type AppAbility = MongoAbility<[Actions, Subjects]>;

/**
 * Build CASL ability from user permissions
 *
 * @param user - Current user
 * @param workspace - Current workspace context
 * @param permissions - User's permissions in this workspace
 */
export function defineAbilitiesFor(
  user: User,
  workspace: Workspace,
  permissions: Permission[]
): AppAbility {
  const { can, cannot, build } = new AbilityBuilder<AppAbility>(createMongoAbility);

  // ===== Owner: Full access bypass =====
  if (user.id === workspace.owner_id) {
    can('manage', 'all');
    return build();
  }

  // ===== Super Admin: Full access with restrictions =====
  const orgId = workspace.parent_id || workspace.id;
  const isSuperAdmin = user.superAdminOrgs?.includes(orgId);

  if (isSuperAdmin) {
    can('manage', 'all');

    // Explicit restrictions (Super Admin CANNOT do these)
    cannot('delete', 'Organization');
    cannot('modify', 'User', { isOwner: true });
    cannot('assign', 'SuperAdminRole');

    return build();
  }

  // ===== Normal users: Map granular permissions =====
  permissions.forEach(perm => {
    const [resource, action] = perm.full_name.split('.');
    const subject = mapResourceToSubject(resource);
    can(action as Actions, subject);
  });

  return build();
}

/**
 * Map database resources to CASL subjects
 */
function mapResourceToSubject(resource: string): Subjects {
  const mapping: Record<string, Subjects> = {
    'boards': 'Board',
    'cards': 'Card',
    'card_comments': 'Comment',
  };
  return mapping[resource] || 'all';
}

React Integration Pattern:

Specify how UI components will use CASL:

// ===== React Context (features/rbac/context/AbilityContext.tsx) =====
import { createContext } from 'react';
import { AppAbility } from '../entities';

export const AbilityContext = createContext<AppAbility | null>(null);

// ===== Custom Hook (features/rbac/hooks/useAppAbility.ts) =====
import { useContext } from 'react';
import { AbilityContext } from '../context/AbilityContext';

export function useAppAbility() {
  const ability = useContext(AbilityContext);
  if (!ability) throw new Error('AbilityContext not provided');
  return ability;
}

// ===== Usage in Components =====
import { Can } from '@casl/react';
import { useAppAbility } from '@/features/rbac/hooks/useAppAbility';

function KanbanBoard() {
  const ability = useAppAbility();

  return (
    <div>
      {/* Declarative visibility with Can component */}
      <Can I="create" a="Board" ability={ability}>
        <CreateBoardButton />
      </Can>

      {/* Programmatic check */}
      {ability.can('delete', 'Board') && (
        <DeleteBoardButton />
      )}
    </div>
  );
}

⚠️ CRITICAL: CASL vs RLS

CASL and RLS serve different purposes:

┌─────────────────────────────────────────┐
│  CLIENT-SIDE (CASL)                     │
│  - UX authorization                      │
│  - Show/hide UI elements                │
│  - Enable/disable actions                │
│  - NOT security (can be bypassed)        │
└─────────────────────────────────────────┘
              ↓ HTTP Request
┌─────────────────────────────────────────┐
│  SERVER-SIDE (RLS)                      │
│  - REAL security                         │
│  - Database-level enforcement            │
│  - Cannot be bypassed                    │
│  - Final source of truth                 │
└─────────────────────────────────────────┘

Both are mandatory. CASL improves UX, RLS enforces security.

Deliverables for Phase 2.5:

In your PRD, include:

CASL subject mapping table
AppAbility type definition
defineAbilitiesFor() function in entities.ts
Owner bypass logic
Super Admin bypass + restrictions
Normal user permission mapping
mapResourceToSubject() helper
React integration examples (<Can>, hooks)
Explanation of CASL vs RLS roles

Reference:

CASL Official Docs: https://casl.js.org/v6/en/guide/intro
CASL React Integration: https://casl.js.org/v6/en/package/casl-react

Phase 3: Special Roles Integration

Questions to answer:

Owner access: Does Owner have automatic full access? (Usually yes)
Super Admin access: Does Super Admin have full access? (Usually yes, with restrictions)
Protected actions: Are there actions only Owner can perform?
Project creation: If this is an org-level feature, can it create projects?

Critical rules:

Owner and Super Admin bypass normal permission checks
Owner can always manage Super Admins
Super Admin cannot modify Owner or other Super Admins
Super Admin cannot assign Super Admin role
Only Owner can delete organizations

Reference file to consult:

Special roles: SPECIAL_ROLES.md - Owner and Super Admin privileges, restrictions, hierarchy

Phase 4: Feature Activation Strategy

Questions to answer:

Default activation: Should this feature auto-activate in new workspaces?
Mandatory feature: Is this feature required system-wide? (Rare, only permissions-management)
Configuration options: Does the feature need workspace-specific config?
Dependencies: Does this feature require other features to be active?

Implementation in entities.ts:

// Feature definition (goes in global features catalog)
export const KanbanFeatureSchema = z.object({
  id: z.string().uuid(),
  slug: z.literal('kanban'),
  name: z.string(),
  description: z.string(),
  category: z.string(),
  is_mandatory: z.boolean().default(false),
});

// Workspace feature activation
export const WorkspaceFeatureSchema = z.object({
  workspace_id: z.string().uuid(),
  feature_id: z.string().uuid(),
  enabled: z.boolean().default(true),
  config: z.record(z.unknown()).optional(), // JSONB config
});

Reference file to consult:

Feature system: FEATURES.md - Feature catalog, activation, independence

Phase 5: Visibility Rules with CASL

Design how users see this feature in the UI:

Minimum permission: What's the least permission needed to see the feature?
Owner/Super Admin: Always visible if feature is active
Normal users: Visible only if they have at least one permission
Component-level: Which UI elements require specific permissions?

CASL Integration for Visibility:

Use CASL's <Can> component and ability.can() checks for UI visibility:

// ===== Feature-Level Visibility =====
import { useAppAbility } from '@/features/rbac/hooks/useAppAbility';

function useFeatureVisibility(featureSlug: string) {
  const { user, workspace } = useWorkspace();
  const ability = useAppAbility();

  // Owner/Super Admin bypass
  if (user.isOwner || user.isSuperAdmin) {
    return isFeatureActive(featureSlug, workspace);
  }

  // Check if user has ANY permission from feature
  const feature = getFeature(featureSlug);
  const hasPermission = feature.resources.some(resource => {
    const subject = mapResourceToSubject(resource);
    return ability.can('read', subject);
  });

  return hasPermission;
}

// ===== Usage in Navigation =====
function Navigation() {
  const showKanban = useFeatureVisibility('kanban');

  return (
    <nav>
      {showKanban && (
        <NavItem href="/kanban">Kanban</NavItem>
      )}
    </nav>
  );
}

Component-Level Visibility with <Can>:

import { Can } from '@casl/react';
import { useAppAbility } from '@/features/rbac/hooks/useAppAbility';

function KanbanBoard({ board }: { board: Board }) {
  const ability = useAppAbility();

  return (
    <div>
      <h1>{board.name}</h1>

      {/* Declarative: Create Button */}
      <Can I="create" a="Card" ability={ability}>
        <CreateCardButton boardId={board.id} />
      </Can>

      {/* Declarative: Delete Button */}
      <Can I="delete" a="Board" ability={ability}>
        <DeleteBoardButton boardId={board.id} />
      </Can>

      {/* Programmatic: Conditional UI */}
      <div className="actions">
        {ability.can('update', 'Board') && (
          <EditBoardButton board={board} />
        )}
        {ability.can('move', 'Card') && (
          <DragAndDropHandle />
        )}
      </div>

      {/* Inverted: Show message when user CANNOT do something */}
      <Can not I="create" a="Card" ability={ability}>
        <p className="text-muted">
          You don't have permission to create cards
        </p>
      </Can>
    </div>
  );
}

Field-Level Visibility (Advanced):

CASL supports field-level permissions for fine-grained visibility:

// Define field-level permissions in ability
can('read', 'Board', ['name', 'description']); // Can see name and description
can('read', 'Board', ['budget'], { isOwner: true }); // Only owners see budget

// Check field access
const canSeeBudget = ability.can('read', 'Board', 'budget');

// UI implementation
function BoardDetails({ board }: { board: Board }) {
  const ability = useAppAbility();

  return (
    <div>
      <h2>{board.name}</h2>
      <p>{board.description}</p>

      {/* Budget only visible to owners */}
      {ability.can('read', subject('Board', board), 'budget') && (
        <div>Budget: ${board.budget}</div>
      )}
    </div>
  );
}

Loading State Pattern:

While abilities are loading, show skeleton UI:

function ProtectedPage() {
  const { ability, isLoading } = useAbilityWithLoading();

  if (isLoading) {
    return <SkeletonLoader />;
  }

  return (
    <Can I="read" a="Board" ability={ability}>
      <BoardList />
    </Can>
  );
}

Example visibility logic (CASL version):

// User sees "Kanban" in menu if:
// - Owner/Super Admin (ability.can('manage', 'all') === true), OR
// - Has ANY permission: ability.can('read', 'Board') || ability.can('create', 'Board') || ...

// User sees "Create Board" button if:
// - ability.can('create', 'Board') === true

Deliverables for Phase 5:

In your PRD, include:

Feature-level visibility hook using CASL
<Can> component usage examples for all major actions
Programmatic ability.can() checks for conditional UI
Field-level visibility examples (if applicable)
Loading states while abilities are fetched
Inverted checks (<Can not>) for permission denial messages

Visibility system: VISIBILITY.md - UI visibility, feature gates, permission-based rendering
CASL React Docs: https://casl.js.org/v6/en/package/casl-react

Phase 6: Database Schema and Security Layers

Design RLS-ready schema:

Workspace foreign key: All feature tables MUST reference workspaces.id
RLS policies: Plan policies for Owner, Super Admin, and normal users
Multi-tenancy: Ensure workspace_id filters prevent cross-workspace access
Cascading deletes: Plan what happens when workspace is deleted

Example schema pattern:

CREATE TABLE kanban_boards (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  workspace_id UUID NOT NULL REFERENCES workspaces(id) ON DELETE CASCADE,
  name TEXT NOT NULL,
  created_by UUID REFERENCES auth.users(id),
  created_at TIMESTAMPTZ DEFAULT NOW()
);

-- RLS Policy
CREATE POLICY "Users can access boards in their workspaces"
ON kanban_boards FOR SELECT
TO authenticated
USING (
  -- Owner bypass
  workspace_id IN (
    SELECT id FROM workspaces
    WHERE owner_id = auth.uid()
  )
  OR
  -- Super Admin bypass
  workspace_id IN (
    SELECT organization_id FROM organization_super_admins
    WHERE user_id = auth.uid()
  )
  OR
  -- Normal user with permission
  user_can(auth.uid(), 'read', 'boards', workspace_id)
);

⚡ Security Layers: CASL + RLS Coordination

CASL and RLS work together as defense in depth:

│  Security: ✅ FINAL SOURCE OF TRUTH                       │
└──────────────────────────────────────────────────────────┘

Example Flow:

// ===== CLIENT SIDE =====
// Step 1: User clicks "Delete Board"
function BoardActions({ board }) {
  const ability = useAppAbility();

  // CASL check: Should we even show the button?
  if (!ability.can('delete', 'Board')) {
    return null; // Button not rendered
  }

  async function handleDelete() {
    // CASL check passed, send request
    const response = await fetch(`/api/boards/${board.id}`, {
      method: 'DELETE',
    });

    // If RLS denies, we get 403 error here
    if (!response.ok) {
      alert('Permission denied');
    }
  }

  return <button onClick={handleDelete}>Delete</button>;
}

// ===== SERVER SIDE (RLS) =====
-- Step 2: Supabase receives DELETE query
DELETE FROM kanban_boards WHERE id = '...';

-- Step 3: RLS policy checks
-- Policy evaluates:
-- 1. Is user the owner? workspace_id IN (SELECT ...)
-- 2. Is user super admin? workspace_id IN (SELECT ...)
-- 3. Does user have permission? user_can(auth.uid(), 'delete', 'boards', ...)

-- If ANY condition is true → DELETE succeeds
-- If ALL conditions are false → ERROR: permission denied

Why Both Layers?

Scenario	CASL Only	RLS Only	CASL + RLS (Recommended)
Authorized user	✅ Button shown	✅ DELETE succeeds	✅ Button shown, DELETE succeeds
Unauthorized user	✅ Button hidden	✅ DELETE blocked	✅ Button hidden, DELETE blocked (if bypassed)
Attacker bypasses CASL	❌ Button shown via DevTools	✅ DELETE blocked	✅ DELETE blocked (RLS protects)
Performance	✅ No unnecessary requests	❌ Sends request then fails	✅ No unnecessary requests
UX	✅ Clean UI	❌ Buttons shown, fail on click	✅ Clean UI

Architectural Rules:

CASL mirrors RLS: CASL permissions should match what RLS allows
RLS is source of truth: If there's a conflict, RLS wins
Both are mandatory: Never rely on CASL alone for security
Test RLS independently: Assume CASL can be bypassed
Keep them in sync: When RLS changes, update CASL definitions

In Your PRD:

Document both layers:

## Security Architecture

### Client-Side Authorization (CASL)
- Users with `boards.create` permission see "Create Board" button
- Implemented via `<Can I="create" a="Board">`

### Server-Side Security (RLS)
- PostgreSQL policy enforces permission check
- Queries auth.uid() from JWT
- Calls user_can() function for verification

### Sync Strategy
- CASL abilities loaded from same permissions table as RLS
- Permissions cached for 5 minutes in TanStack Query
- Realtime invalidation ensures <500ms sync

Common Architect Mistakes to Avoid

General RBAC Mistakes

❌ Assuming feature inheritance between org and projects ✅ Each workspace activates features independently

❌ Creating "Owner of project" role ✅ Owner only exists at organization level

❌ Hardcoding Owner/Super Admin permissions in permission tables ✅ Owner/Super Admin use bypass logic, not permission tables

❌ Mixing business logic with permissions ✅ Permissions are pure access control; business rules go in use cases

❌ Forgetting workspace_id in entities ✅ All feature entities must reference workspace

❌ Creating permissions without resources ✅ Always define resources first, then permissions on those resources

❌ Ignoring RLS in schema design ✅ Plan RLS policies during entity design

CASL-Specific Mistakes

❌ Treating CASL as security ✅ CASL is UX authorization; RLS is real security

❌ Not defining CASL subjects in PRD ✅ Architect must specify subject mapping for each resource

❌ Using different permission formats in CASL vs database ✅ Maintain consistent resource.action format everywhere

❌ Forgetting cannot() rules for Super Admin restrictions ✅ Define explicit restrictions: cannot('delete', 'Organization')

❌ Not syncing CASL with RLS changes ✅ When RLS policies change, update defineAbilitiesFor() accordingly

❌ Hardcoding abilities instead of loading from database ✅ Load permissions from Supabase, then build CASL abilities dynamically

❌ Missing type safety for subjects and actions ✅ Define TypeScript types: type AppAbility = MongoAbility<[Actions, Subjects]>

❌ Not handling ability loading states ✅ Show skeleton UI while abilities are being fetched

## Final Note

This system is **highly modular and flexible**. The key is understanding that:

1. **Workspaces are independent** - No sharing, no inheritance
2. **Features are modular** - Can be activated anywhere
3. **Permissions are contextual** - Only apply in specific workspace
4. **Owner/Super Admin are special** - Bypass normal rules with specific restrictions

When in doubt, consult the reference files and remember: **explicit is better than implicit**.
