saas-seeder（萨斯播种机）

Platform Notes

• Optional helper plugins may help in some environments, but they must not be treated as required for this skill.

SaaS Seeder Template Bootstrap

Use When

• Bootstrap a new SaaS from the SaaS Seeder Template: setup database, configure environment, create super admin user, and verify three-tier panel structure. Use when initializing a new multi-tenant SaaS project from this template.
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to saas-seeder or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve; load references only as needed.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.

Workflow

• Read this SKILL.md first, then load only the referenced deep-dive files that are necessary for the task.
• Apply the ordered guidance, checklists, and decision rules in this skill instead of cherry-picking isolated snippets.
• Produce the deliverable with assumptions, risks, and follow-up work made explicit when they matter.

Quality Standards

• Keep outputs execution-oriented, concise, and aligned with the repository's baseline engineering standards.
• Preserve compatibility with existing project conventions unless the skill explicitly requires a stronger standard.
• Prefer deterministic, reviewable steps over vague advice or tool-specific magic.

Anti-Patterns

• Treating examples as copy-paste truth without checking fit, constraints, or failure modes.
• Loading every reference file by default instead of using progressive disclosure.

Outputs

• A concrete result that fits the task: implementation guidance, review findings, architecture decisions, templates, or generated artifacts.
• Clear assumptions, tradeoffs, or unresolved gaps when the task cannot be completed from available context alone.
• References used, companion skills, or follow-up actions when they materially improve execution.

Bootstrap a new multi-tenant SaaS project using the SaaS Seeder Template with proper three-tier panel architecture, Argon2ID authentication, and franchise isolation.

Security Baseline (Required)

Always load and apply the Vibe Security Skill for any seeder work that touches web pages, APIs, authentication, data access, or file handling. Treat its checklist as mandatory.

Database Standards (Required)

All database schema setup, seeding, and migrations MUST follow mysql-best-practices skill patterns including character sets, indexing, foreign keys, and stored procedures.

Standard Deployment Environments

All SaaS projects deploy across three environments:

Cross-platform rules: Use utf8mb4_unicode_ci collation. Match file/directory case exactly (Linux is case-sensitive). Use forward slashes in PHP paths. Production migrations go in database/migrations-production/ (non-destructive, idempotent).

When to Use

Use when the user says:

• "Using the seeder-script skill, prepare this repository for [SaaS name]"
• "Bootstrap a new SaaS from this template"
• "Initialize the SaaS Seeder Template"
• "Setup database for new SaaS project"
• "Start a new project from the template"

Project Preparation Workflow

BEFORE bootstrapping, developers MUST provide:

1. Requirements & Design Specifications

Place in docs/project-requirements/:

docs/project-requirements/
├── requirements.md          # Detailed feature requirements
├── business-rules.md         # Business logic and validation rules
├── user-types.md             # User types and their permissions
├── workflows.md              # Key user workflows and processes
└── ui-mockups/               # UI mockups or wireframes (optional)

Use the project-requirements skill to create these files with AI assistance.

1.1 Documentation Readiness (Required)

• Confirm end-user manual scope is defined for each core feature
• Plan manual locations in /manuals/ and a public entry point (e.g., /public/user-manuals.php)
• Ensure specs are written in a way that can be translated into manuals and step-by-step guides

2. Database Schema Files

Place in database/schema/:

database/schema/
├── core-schema.sql           # Main database schema
├── seed-data.sql             # Sample/seed data (optional)
└── schema-diagram.png        # Database diagram (optional)

Schema Requirements:

• All franchise-scoped tables MUST have franchise_id column
• Use utf8mb4_unicode_ci collation
• Include proper indexes and foreign keys

AI Agent Preparation Steps

When starting a new project:

1. Read Project Requirements

- Load all files from docs/project-requirements/ - Understand user types, workflows, business rules - Identify custom tables needed beyond template defaults

1. Review Database Schema

- Read schema files from database/schema/ - Validate against multi-tenant patterns (franchise_id filtering) - Ensure collation is utf8mb4_unicode_ci - Check for proper indexes and foreign keys

1. Update Project Documentation

- Replace README.md with project-specific content - Update CLAUDE.md with project-specific guidance - Remove template docs from docs/ (keep only project-relevant ones) - Add project-specific documentation based on requirements - Ensure docs/plans/INDEX.md exists as the master plan status index and is maintained as plans are created or updated

1. Customize Template

- Update branding (SaaS Seeder → Project Name) - Set SESSION_PREFIX to project-specific value - Customize user types enum if needed - Update environment variable examples - Register GIS settings when mapping is required (tile provider keys such as system_settings.osm_api_key)

1. Validate Completeness

- Check all requirements are documented - Verify database schema follows multi-tenant patterns - Ensure session prefix is customized - Confirm user types match requirements

Critical Architecture Standards

See references/architecture.md for complete details.

Three-Tier Panel Structure (CORE Concept)

1. /public/ (root) - Franchise Admin Panel (THE MAIN WORKSPACE)

- Single franchise management - User types: owner, staff - Files: dashboard.php, skeleton.php

1. /public/adminpanel/ - Super Admin Panel

- System-wide management - Multi-franchise oversight - User type: super_admin

1. /public/memberpanel/ - End User Portal

- Self-service for end users - User types: member, student, customer, patient

Key Principle: /public/ root is NOT a redirect router - it's the franchise admin workspace!

Session Prefix System

All session variables use a prefix:

define('SESSION_PREFIX', 'saas_app_'); // Change per SaaS

// ALWAYS use helpers
setSession('user_id', 123);        // Sets $_SESSION['saas_app_user_id']
$userId = getSession('user_id');   // Gets $_SESSION['saas_app_user_id']
hasSession('user_id');             // Checks if exists

Customize per SaaS: school_, restaurant_, clinic_, etc.

Password Hashing

Uses Argon2ID (NOT bcrypt):

Algorithm: Argon2ID + salt(32 chars) + pepper(64+ chars)
Hash: salt + Argon2ID(HMAC-SHA256(password, pepper) + salt)

CRITICAL: Use super-user-dev.php to create admin users, NOT migration defaults!

Required Files And Paths

• docs/seeder-template/migration.sql - Core auth/RBAC schema
• docs/seeder-template/fix-collation-and-create-franchises.sql - Collation fixes + franchises table
• docs/project-requirements/ - Project requirements (developer provides)
• database/schema/ - Project database schemas (developer provides)
• public/super-user-dev.php - Super admin creator (DEV ONLY)
• public/dashboard.php - Franchise admin dashboard
• public/skeleton.php - Page template
• .env - Environment configuration

Standard Workflow

See references/workflow.md for complete step-by-step guide.

Quick Bootstrap Steps

1. Environment Setup

- Ask for DB credentials, cookie domain, encryption keys - Create/update .env file

1. Install Dependencies composer install
2. Install PHP Development Tools See references/php-tooling.md for complete setup guide. Quick install: # Check existing tools composer show | grep -E "(phpstan|phpunit|pest|php-cs-fixer)" # Install essential tools composer require --dev phpstan/phpstan composer require --dev friendsofphp/php-cs-fixer composer require --dev pestphp/pest --with-all-dependencies Create configs and add composer scripts (see references/php-tooling.md for details).
3. Database Setup .\setup-database.ps1 # Windows PowerShell
4. Fix Collations .\fix-database.ps1 # Creates franchises table
5. Create Super Admin

- Visit http://localhost:8000/super-user-dev.php - Uses correct Argon2ID hashing

1. Verify Setup

- Login at http://localhost:8000/sign-in.php - See landing page with navigation buttons

1. Project Customization

- Update SESSION_PREFIX in src/config/session.php - Customize user types enum - Apply project database schema - Update branding throughout - Create project-specific CLAUDE.md

Seeding Rules

User Types & Franchise Requirements

• super_admin - Platform operators (franchise_id CAN be NULL)
• owner - Franchise owners (franchise_id REQUIRED)
• staff - Franchise staff with permissions (franchise_id REQUIRED)
• Custom types - End users (franchise_id REQUIRED)

Franchise Data

ALWAYS filter by franchise_id:

// CORRECT
$stmt = $db->prepare("SELECT * FROM students WHERE franchise_id = ?");
$stmt->execute([getSession('franchise_id')]);

// WRONG - data leakage!
$stmt = $db->prepare("SELECT * FROM students");

Permission Codes

• Uppercase with underscores
• Format: RESOURCE_ACTION
• Examples: INVOICE_CREATE, STUDENT_DELETE, REPORT_VIEW

Troubleshooting

See references/troubleshooting.md for complete guide.

Common Issues

Session Not Persisting

• HTTPS auto-detection already handled
• Localhost HTTP works without HTTPS requirement

Password Mismatch

• Use super-user-dev.php, NOT manual password_hash()
• Template uses Argon2ID, not bcrypt

Collation Errors

• Run .\fix-database.ps1
• Fixes utf8mb4_unicode_ci mismatches

Missing Franchises Table

• Run .\fix-database.ps1
• Creates tbl_franchises with default data
