# Technical Writer Audit Report — GoodGo POS System

**Auditor**: Technical Writer Agent
**Date**: 2026-03-20
**Scope**: Documentation quality, API docs, README files, code comments
**Working Directory**: `/Users/velikho/Desktop/WORKING/pos-system`

---

## Executive Summary

The GoodGo Platform has a strong documentation foundation — 102+ markdown files in `/docs`, bilingual EN/VI coverage, and `SERVICE_DOCS.md` for all 25 microservices. The primary gaps are **service-level README files** (52% missing) and **OpenAPI specification files** (96% missing across services), both of which are addressable without major effort.

---

## Critical Issues

### C1 — OpenAPI Specs Missing for 24/25 Services
**Severity**: Critical
**Location**: `/docs/en/api/openapi/` (only `iam-service.yaml` present)

Only `iam-service.yaml` exists as a committed OpenAPI specification. The remaining 24 services (`merchant-service-net`, `order-service-net`, `fnb-engine-net`, `booking-service-net`, `catalog-service-net`, `inventory-service-net`, `wallet-service-net`, `promotion-service-net`, `membership-service-net`, `chat-service-net`, `social-service-net`, `storage-service-net`, `mining-service-net`, `mission-service-net`, all 5 ads services, all 4 mkt services) have no committed spec file.

**Impact**: No API discoverability for 96% of services. Clients cannot generate SDKs, cannot import into Postman/Insomnia, and there is no machine-readable contract for integration tests.

**Recommendation**: Export Swagger specs from each `.NET` service at build time and commit to `/docs/en/api/openapi/{service-name}.yaml`. Create a script under `scripts/` to automate collection.

---

### C2 — Postman Collections Directory is Empty
**Severity**: Critical
**Location**: `/docs/en/api/postman/` (0 files)

The directory exists but contains no collection files. Without Postman collections, developers must manually reconstruct requests from `SERVICE_DOCS.md`.

**Impact**: Developer onboarding friction — no ready-to-run API test collection.

**Recommendation**: Export Postman collections from Swagger specs or create manually. Commit to `/docs/en/api/postman/{service-name}.json`.

---

## Warnings

### W1 — Service README Files Missing for 13/25 Services (52% Gap)
**Severity**: High
**Affected Services**:
- `ads-analytics-service-net/` — no `README.md`
- `ads-billing-service-net/` — no `README.md`
- `ads-manager-service-net/` — no `README.md`
- `ads-serving-service-net/` — no `README.md`
- `ads-tracking-service-net/` — no `README.md`
- `booking-service-net/` — no `README.md`
- `catalog-service-net/` — no `README.md`
- `fnb-engine-net/` — no `README.md`
- `inventory-service-net/` — no `README.md`
- `order-service-net/` — no `README.md`
- `promotion-service-net/` — no `README.md`
- `social-service-net/` — no `README.md`
- `wallet-service-net/` — no `README.md`

**Mitigation**: All missing-README services have comprehensive `SERVICE_DOCS.md` files (auto-generated, covering API endpoints, database schema, domain models, configuration). This partially compensates, but `README.md` is typically the first file a new developer opens and contains prerequisites and quick-start instructions not found in `SERVICE_DOCS.md`.

**Recommendation**: Add `README.md` to all 13 services using `iam-service-net/README.md` as the template (294 lines, gold standard).

---

### W2 — Missing `storage-service-net/SERVICE_DOCS.md`
**Severity**: Medium
**Location**: `services/storage-service-net/`

`storage-service-net` has a `README.md` but the audit found no corresponding `SERVICE_DOCS.md`. All other services have both. This is an inconsistency in the documentation generation process.

**Recommendation**: Run the documentation generation audit on `storage-service-net` and create `SERVICE_DOCS.md`.

---

### W3 — Architecture Doc `storage-proposal.md` Exists Only in Vietnamese
**Severity**: Medium
**Location**: `/docs/vi/architecture/storage-proposal.md` (EN version missing)

The Vietnamese architecture folder contains `storage-proposal.md` with no corresponding English version at `/docs/en/architecture/storage-proposal.md`. This breaks the bilingual parity maintained across all other documentation.

**Recommendation**: Create `/docs/en/architecture/storage-proposal.md` as an English translation of the Vietnamese file.

---

### W4 — No CHANGELOG / Release Notes
**Severity**: Medium
**Location**: Root level (no `CHANGELOG.md`)

No formal release history exists. While conventional commits (`feat:`, `fix:`, `docs:`) provide an informal changelog via `git log`, there is no generated or maintained `CHANGELOG.md`.

**Mitigation**: Commit messages follow conventional commits format consistently — this is recoverable.

**Recommendation**: Add a root `CHANGELOG.md` and automate generation using `standard-changelog` or `conventional-changelog` as part of the release CI pipeline.

---

### W5 — `packages/config/README.md` Missing
**Severity**: Low
**Location**: `packages/config/` (no `README.md`)

5/6 shared Node.js packages have README files. `@goodgo/config` is undocumented.

**Recommendation**: Create `packages/config/README.md` documenting configuration variables, usage, and examples. Use `packages/types/README.md` as a template.

---

## Improvements

### I1 — No Visual System Architecture Diagram
Architecture docs are text-heavy but there is no Mermaid or D2 diagram showing all 25 services, their communication patterns, and data flows in a single view. `/docs/en/architecture/system-design.md` covers this conceptually but lacks a visual overview.

**Recommendation**: Add a Mermaid `graph LR` or `C4Context` diagram to `system-design.md` illustrating service topology.

---

### I2 — VitePress Documentation Site Not Publishing Architecture Docs
`/apps/web-docs/` is configured (VitePress v1.6.3, Mermaid plugin) but the deployment/CI pipeline does not appear to publish the documentation site. The `web-docs` package has `dev`, `build`, `preview` scripts but no CI workflow (`ci-web-docs.yml`) to deploy it.

**Recommendation**: Add a GitHub Actions workflow to build and deploy the VitePress site to GitHub Pages or a subdomain (e.g., `docs.goodgo.vn`).

---

### I3 — `.cursor/skills/` and `/docs/skills/` Duplication
Skills documentation exists in two places: `.cursor/skills/` (15 skill files) and `/docs/en/skills/` (13+ docs). They are partially overlapping. This creates maintenance burden — updates may be applied to one location and not the other.

**Recommendation**: Establish a single source of truth. Either have `.cursor/skills/` reference `/docs/en/skills/`, or consolidate into one location with symlinks.

---

### I4 — No API Documentation Index
There is no `/docs/en/api/README.md` or central index listing all services, their Swagger UI URLs (e.g., `http://localhost:{port}/swagger`), and their OpenAPI spec paths. Developers must know which service runs on which port.

**Recommendation**: Create `/docs/en/api/README.md` with a table:

| Service | Port | Swagger UI | OpenAPI Spec |
|---------|------|------------|--------------|
| iam-service-net | 5001 | http://localhost:5001/swagger | openapi/iam-service.yaml |
| merchant-service-net | 5002 | http://localhost:5002/swagger | — |
| ... | ... | ... | ... |

---

### I5 — MCP Server Documentation Could Be Expanded
`services/goodgo-mcp-server/SERVICE_DOCS.md` covers the 12 MCP tools but lacks a dedicated integration guide for AI clients (Claude, Cursor, etc.) showing how to configure the server, authenticate, and invoke each tool with examples.

**Recommendation**: Create `services/goodgo-mcp-server/docs/integration-guide.md` with per-tool usage examples and configuration instructions for AI clients.
