Automated summary

Generates new code files for a new module in the 9Trip ERP system, following strict rules on schema validation, data access via DBManager, and state management.

Strengths

  • Ensures adherence to single source of truth via DB_SCHEMA
  • Enforces proper data access through DBManager preventing direct Firestore calls
  • Promotes consistency by using schema-defined naming and initial values
  • Reduces errors with client-side sorting and history tracking considerations

Limitations

  • Requires deep familiarity with the custom 9Trip ERP framework and DBManager API
  • Not applicable outside the specific ERP system context
  • May generate boilerplate that needs manual adjustment for unique business logic
When to use it

Use when starting a new module or adding new CRUD operations to an existing module within the 9Trip ERP system.

When not to use it

Do not use for general code generation or projects not based on the 9Trip ERP architecture.

Security analysis

Safe
Quality score75/100

The skill provides coding guidelines for data access and persistence within a specific ERP system. It does not instruct any destructive actions, data exfiltration, or execution of arbitrary commands; it is limited to internal implementation patterns.

How this analysis is made

Examples

Create supplier module
Create a new module for managing suppliers in the 9Trip ERP system. Follow the new module creation rules: use DB_SCHEMA for field definitions, access data only through DBManager, and ensure snake_case variable names.
Add CRUD for products
Generate the necessary files for a new 'products' module in the 9Trip ERP. Include schema validation from DB_SCHEMA, data persistence via DBManager saveRecord and deleteRecord, and proper state management with IndexedDB cache priority.
Initialize module with sample code
I need to create a new 'orders' module in our 9Trip ERP. Please generate the code skeleton including the DB_SCHEMA entries, the CRUD functions using A.DB, and the UI form generation based on schema metadata. Remember to use snake_case and initial values.

Instructions

Bạn phải tuân thủ nghiêm ngặt các quy tắc dưới đây khi tương tác với dữ liệu của 9Trip ERP:

1. SINGLE SOURCE OF TRUTH (DBSchema.js)

  • Validation: Trước khi viết hàm lưu dữ liệu, phải đối chiếu với DB_SCHEMA. Ví dụ: Booking ID phải khớp pattern ^BK\d{4,}$.
  • UI Generation: Luôn sử dụng metadata từ schema (displayName, type, placeholder) để render form. Không tự ý hard-code nhãn hoặc kiểu input.
  • Initial Values: Khi tạo object mới, phải lấy giá trị từ trường initial trong schema (ví dụ: initial: 'today' hoặc initial: 1).

2. DATA ACCESS & PERSISTENCE (DBManager.js)

  • Single Point of Write: TUYỆT ĐỐI KHÔNG dùng trực tiếp db.collection().add() hay set(). Mọi thao tác ghi/xóa phải đi qua hàm firestoreCRUD(collection, action, id, data) của module DBManager bằng cách gọi qua global object của DBManager là A.DB (ví dụ gọi A.DB.tên hàm như saveRecord, batchSave, deleteRecord, getCollection...).
  • Client-Side Sorting: Khi lấy dữ liệu, KHÔNG dùng orderBy của Firestore vì sẽ bị mất document thiếu field. Luôn để DBManager xử lý postSort sau khi hydrate dữ liệu.
  • History Tracking: Lưu ý rằng các collection bookings, booking_details, transactions đã được cấu hình tự động ghi History. Khi cập nhật các bảng này, hệ thống sẽ tự động ghi vết vào bookings.history.
  • Indexing: Sử dụng INDEX_CONFIG trong DBManager để truy cập nhanh các dữ liệu nhóm (ví dụ: lấy tất cả booking_details theo booking_id).

3. STATE & CACHE MANAGEMENT

  • Cache Priority: Hiểu rằng DBManager ưu tiên IndexedDB (72h). Nếu cần dữ liệu mới nhất ngay lập tức, phải sử dụng cơ chế syncDelta hoặc loadCollections với tham số forceNew = true.
  • Variable Consistency: Luôn giữ đúng tên biến snake_case như định nghĩa trong Schema (ví dụ: customer_full_name, không được đổi thành customerFullName).

4. CRITICAL LOGIC

  • Khi thực hiện CRUD, luôn bọc trong try-catch và sử dụng log() của hệ thống để theo dõi.
  • Nếu chỉnh sửa liên quan đến tiền tệ, phải dùng hàm format từ utils.js phối hợp với trường total_amount trong Schema.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/new-module-creation-mmk3nifx/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/new-module-creation-mmk3nifx' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/new-module-creation-mmk3nifx/download' --output '.skill-downloads/new-module-creation-mmk3nifx/SKILL.md.part' && mv '.skill-downloads/new-module-creation-mmk3nifx/SKILL.md.part' '.skill-downloads/new-module-creation-mmk3nifx/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/new-module-creation-mmk3nifx/SKILL.md' && test -s '.skill-downloads/new-module-creation-mmk3nifx/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/new' && cp -R '.skill-downloads/new-module-creation-mmk3nifx' '.claude/skills/new'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/new-module-creation-mmk3nifx'

openskills read 'new-module-creation-mmk3nifx'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/new-module-creation-mmk3nifx/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
