-# pchome-cli
-
-`pchome` is a Go CLI for searching PChome 24h products, viewing product details, comparing products, and getting recommendations.
+Fast, script-friendly CLI for searching PChome 24h products, viewing product details, comparing products, and getting recommendations. JSON-first output, human-friendly tables, and a normalized schema built in.
 
-The CLI is optimized for two modes:
+## Features
 
-- Human-friendly text output for browsing and decision-making.
-- Agent-friendly `json` and `ndjson` output with a normalized schema (`v1`).
-
-The default human-facing language is Traditional Chinese (Taiwan). To switch the app to English, set `i18n.language = "en"` in `~/.pchome/config.toml`.
+- **Search** - search products with filters for brand, price range, rating, stock status, 24h arrival, sorting, and custom column output
+- **View** - display detailed product information including specs, images, and warnings
+- **Recommend** - get product recommendations based on a reference product, with optional reasoning
+- **Compare** - compare multiple products side-by-side with customizable columns
+- **Suggest** - get autocomplete suggestions for search queries
+- **Multi-format output** - human-friendly text tables, JSON, and NDJSON for scripting and agent integrations
+- **Normalized schema** - stable English schema keys (`v1`) regardless of locale, so agent integrations do not break
+- **i18n** - Traditional Chinese (default) and English interface
+- **Flexible product input** - accepts raw IDs (`DRAA5K-A900JOK9O`), suffixed IDs (`DRAA5K-A900JOK9O-000`), or full PChome URLs
+- **Configurable** - per-command defaults, column ordering, and output preferences via `~/.pchome/config.toml`

-
-Recommended maintainer workflow:
+### Pipe JSON output to jq
 
 ```bash
-# Fast local build for the current platform
-make build
-
-# Unit tests + GoReleaser config validation
-make verify
-
-# Simulate a full release locally into ./dist
-make release-snapshot
+# Extract product names under a price threshold
+pchome search "掃地機器人" --format json | jq '.products[] | select(.price < 10000) | .name'
 ```
 
-On first run, `make verify` and `make release-snapshot` automatically download and cache the pinned GoReleaser version.
-
-For an actual release:
+### Stream results with NDJSON
 
 ```bash
-git tag -a v0.1.0 -m "v0.1.0"
-git push origin v0.1.0
+pchome search "掃地機器人" --limit 20 --format ndjson | while read -r line; do
+  echo "$line" | jq -r '.name'
+done
 ```
 
-After a `v*` tag is pushed, GitHub Actions runs the release workflow and GoReleaser publishes macOS, Linux, and Windows archives for `amd64` and `arm64`, plus `checksums.txt`, to GitHub Releases.
-
-Homebrew / Scoop also require a small amount of one-time setup:
-
-- Create an `oliyy/homebrew-tap` repository for `Formula/pchome-cli.rb`
-- Create an `oliyy/scoop-bucket` repository for `pchome-cli.json`
-- Add a `PACKAGE_REPOS_TOKEN` GitHub Actions secret to `pchome-cli`
-- That token needs write access to both repositories
-
-Notes:
+## 
 
-- The Homebrew path here is a personal tap, not `homebrew/core`
-- GoReleaser updates the tap and bucket on normal release tags; prerelease tags are skipped automatically

-`pchome` 是一個以 Go 撰寫的 PChome 24h CLI，可用來搜尋商品、檢視商品詳情、比較商品，以及取得推薦結果。
+## 功能特色
 
-CLI 針對兩種使用方式設計：
+- **搜尋 (Search)** - 支援透過關鍵字搜尋商品，並可依照品牌、價格區間、評價、庫存狀態、24h 到貨、排序方式進行篩選，同時支援自訂輸出欄位
+- **檢視 (View)** - 顯示詳細的商品資訊，包含規格、圖片以及相關警告提示
+- **推薦 (Recommend)** - 根據指定商品取得相關的推薦商品，並可選擇顯示推薦原因
+- **比較 (Compare)** - 並排比較多項商品，支援自訂顯示欄位
+- **建議 (Suggest)** - 提供搜尋關鍵字的自動補全與建議
+- **多種輸出格式** - 支援適合閱讀的文字表格格式、供腳本使用的 JSON 格式，以及適合串流或 AI 代理程式（Agent）整合的 NDJSON 格式
+- **標準化資料結構 (Schema)** - 無論語系為何，皆維持穩定的英文欄位鍵值（`v1`），確保 AI 代理程式或腳本整合不會因語系切換而失效
+- **多國語系 (i18n)** - 支援繁體中文（預設）與英文介面
+- **彈性的商品輸入格式** - 支援直接輸入商品編號（例如 `DRAA5K-A900JOK9O`）、帶有後綴的編號（例如 `DRAA5K-A900JOK9O-000`），或是完整的 PChome 商品網址
+- **高度可設定** - 可透過 `~/.pchome/config.toml` 設定各指令的預設值、欄位排序以及輸出偏好
 
-- 適合人類閱讀的文字輸出，方便瀏覽與決策。
-- 適合 AI agent 與程式整合的 `json` / `ndjson` 輸出，並提供穩定的標準化 schema（`v1`）。

-- 推薦 API 的 token 讀取順序為 `hermes.token` -> `PCHOME_HERMES_TOKEN` -> 內建 fallback token。
-- 機器可讀輸出一律維持英文 schema key，避免 locale 變動破壞 agent 整合。
-- 目前 schema 版本為 `--schema-version v1`。
-- 執行 `go test ./...` 可跑目前的單元測試。
-
-## 建置與釋出
-
-維護者日常建議流程：
+### 將 JSON 輸出管線連接至 jq
 
 ```bash
-# 目前平台快速建置
-make build
-
-# 單元測試 + 檢查 GoReleaser 設定
-make verify
-
-# 模擬一次完整 release，產物會出現在 ./dist
-make release-snapshot
+# 擷取低於特定價格門檻的商品名稱
+pchome search "掃地機器人" --format json | jq '.products[] | select(.price < 10000) | .name'
 ```
 
-`make verify` / `make release-snapshot` 第一次執行時會自動下載並快取固定版本的 GoReleaser。
-
-正式釋出流程：
+### 使用 NDJSON 進行串流處理
 
 ```bash
-git tag -a v0.1.0 -m "v0.1.0"
-git push origin v0.1.0
+pchome search "掃地機器人" --limit 20 --format ndjson | while read -r line; do
+  echo "$line" | jq -r '.name'
+done
 ```
-
-推上 `v*` tag 之後，GitHub Actions 會執行 release workflow，使用 GoReleaser 建立 macOS、Linux、Windows 的 `amd64` / `arm64` binary archive，並附上 `checksums.txt` 到 GitHub Releases。
-
-Homebrew / Scoop 另外需要先準備：
-
-- 建立 `oliyy/homebrew-tap` repository，讓 GoReleaser 更新 `Formula/pchome-cli.rb`
-- 建立 `oliyy/scoop-bucket` repository，讓 GoReleaser 更新 `pchome-cli.json`
-- 在 `pchome-cli` repository 的 GitHub Actions secrets 加上 `PACKAGE_REPOS_TOKEN`
-- `PACKAGE_REPOS_TOKEN` 需要能寫入上述兩個 repository
-
-補充：
-
-- 目前 Homebrew 走的是「自有 tap」路線，不是 `homebrew/core`
-- GoReleaser 會在正式 release tag 時更新 tap / bucket；prerelease tag 會自動略過

+
+## Development
+
+```bash
+# Fast local build for the current platform
+make build
+
+# Unit tests + GoReleaser config validation
+make verify
+
+# Simulate a full release locally into ./dist
+make release-snapshot
+```
+
+On first run, `make verify` and `make release-snapshot` automatically download and cache the pinned GoReleaser version.
+
+Run unit tests directly:
+
+```bash
+go test ./...
+```
+
+## Build and Release
+
+Recommended maintainer workflow:
+
+```bash
+git tag -a v0.1.0 -m "v0.1.0"
+git push origin v0.1.0
+```
+
+After a `v*` tag is pushed, GitHub Actions runs the release workflow and GoReleaser publishes macOS, Linux, and Windows archives for `amd64` and `arm64`, plus `checksums.txt`, to GitHub Releases.
+
+### Homebrew / Scoop Setup
+
+One-time setup for package manager distribution:
+
+- Create an `oliyy/homebrew-tap` repository for `Formula/pchome-cli.rb`
+- Create an `oliyy/scoop-bucket` repository for `pchome-cli.json`
+- Add a `PACKAGE_REPOS_TOKEN` GitHub Actions secret to `pchome-cli`
+- That token needs write access to both repositories
+
+Notes:
+
+- The Homebrew path here is a personal tap, not `homebrew/core`
+- GoReleaser updates the tap and bucket on normal release tags; prerelease tags are skipped automatically
+
+## Notes
+
+- Recommendation token precedence is `hermes.token` -> `PCHOME_HERMES_TOKEN` -> bundled fallback token.
+- Machine-readable output keeps stable English schema keys regardless of locale, so agent integrations do not break.
+- The current schema version is `--schema-version v1`.
