nl2ledger

Natural language bookkeeping — Claude parses amounts, categories, and timestamps from your input and appends structured entries to a QianJi CSV ledger.

Features

• Chinese, English, or mixed-language input
• Auto-detects amount, merchant, and category
• Multiple entries in one sentence (comma / pause-mark separated)
• Relative time expressions (yesterday, last Friday, 10am…)
• Preview before writing — no accidental entries

CSV File

Place your QianJi CSV file in the project root:

• Export existing data from the QianJi App, or
• Create a blank CSV with only the header row — see skills/nl2ledger/sample/QianJi_sample.csv for the format

Usage

After installation, just type in Claude Code:

午饭麦当劳25块

咖啡18，打车32

昨天晚饭西贝89

lunch 35, coffee 18

Claude will parse, show a preview, and write to CSV upon confirmation.

Customization

• Category rules: Edit references/category_map.md to add your own merchants and spending habits
• Recorder name: Change the default in category_map.md (Default Values section) and scripts/append_entry.py (--recorder)
• Default account: Same files, change the 账户1 default

Note: The category rules and special rules (merchant names, tags, etc.) in this repo are example configurations. Customize them to match your own habits.

cn-holiday

Query Chinese public holidays, 调休 (make-up workdays), and work schedules via the timor.tech API.

Features

• Check if a date is a workday, weekend, holiday, or make-up workday
• Full-year holiday schedule overview
• Overtime pay multiplier info (1x / 2x / 3x)
• No API key required

Usage

exchange-rate

Query real-time and historical exchange rates via the Frankfurter API (ECB data source). Supports 30+ major currencies.

Features

• Real-time currency conversion
• Historical exchange rate lookup
• Supports Chinese currency names (美元, 人民币, 欧元…)
• No API key required

Usage

100美元换人民币

500 EUR to JPY

今天英镑汇率多少

qweather

Query real-time weather, forecasts, and life indices via QWeather (和风天气) API.

Features

• Real-time weather conditions
• Multi-day weather forecast
• Life indices (UV, clothing, car wash, etc.)
• City name lookup (Chinese/English)
• Requires QWEATHER_API_KEY and QWEATHER_API_HOST environment variables

Usage

明天需要带伞吗

上海未来三天天气预报

car-advisor

Real-time car comparison and purchase advisor. Claude searches live data from official sites, Dongchedi, Autohome, and owner reviews to answer any car-related question.

Features

• Multi-car parameter comparison with structured tables
• Real-time pricing from official brand websites
• Owner reviews and ratings from Dongchedi, Autohome, Zhihu
• Budget-based car recommendations
• Smart driving (ADAS) capability comparison
• Sales and market data lookup
• No API key required (uses web search)

Usage

问界M9多少钱

20-30万预算推荐什么新能源SUV

Model Y 焕新版有座椅通风吗

2024年最畅销新能源车排名

Claude will search live data, generate comparison tables, summarize owner feedback, and give purchase recommendations with data sources cited.

mermaid-link

Turn Mermaid diagrams in conversations into clickable preview links. Instead of copying diagram code out of the chat and pasting it into a renderer, you (or anyone you share the link with) just click — the diagram opens in MMD Paper, rendered instantly.

Features

• Works automatically: when Claude generates a Mermaid diagram, it appends a preview link right after the code block
• Also works on demand: paste any Mermaid code and ask for a link
• Links are self-contained — the diagram is encoded in the URL hash, no account, no server storage
• Private by design: the hash fragment never reaches any server; MMD Paper renders 100% client-side
• UTF-8 / Chinese labels fully supported
• No API key required

Usage

Once installed, it kicks in on its own — ask Claude for any diagram:

画一个用户登录流程的时序图

Claude replies with the ```mermaid block plus a link like [▶ Open diagram](https://mmd.dyu.sh/#Zmxvd2NoYXJ0...) — click it and the rendered diagram opens in the browser, where you can switch themes, zoom, and export SVG/PNG.

Or hand it existing code:

把这段 mermaid 变成链接：graph TD; A-->B

打开这个图 / open this diagram

portrait-prompt

De-AI-flavor portrait prompts. Describe the portrait you want and Claude builds a photorealistic prompt through an 8-dimension framework — persona, fabric, moment, lens, light & skin, background, finishing, negatives — runs a mandatory anti-AI-flavor self-check, then adapts the output to your image model.

Features

• Targets the root causes of plastic skin / AI flavor / stock-photo cheapness, not the symptoms
• Hard gates per dimension: numeric age, skin micro-texture four-pack (pores / uneven tone / oil sheen / vellus hair), single motivated key light, real focal length + f-stop, imperfection budget
• Structural risk handling: hands, in-scene text & logos, dense repeating grids, crowd faces
• Mandatory self-check before output: mean-face risk, contrast stacking, saturation traps
• Model dialect adaptation: Midjourney / Stable Diffusion / Flux / GPT-Image / Seedream — negative prompts auto-converted to positive statements for models without a negative channel
• No API key required

Usage

给我一个克制老钱风的人像提示词，用在 Midjourney

体育赛事广播截图风，网球，16:9，Flux 用

a 50-year-old ceramicist in her studio, photoreal portrait prompt, de-AI

share-to-xhs

Publish finished Xiaohongshu copy and ordered local images from a project's share/ or share-rednote/ directory. The skill parses the package deterministically, validates XHS limits, fills the real creator page in the user's Chrome session, pauses for a final visual confirmation, verifies the published note in content management, and records a hash-based receipt to prevent duplicates.

Features

• Supports standard ### 小红书 + ## Attach share-kit chapters
• Supports note.md packages with title choices and carousel order
• Preserves exact copy and image order; never converts X/朋友圈 copy implicitly
• QR-login screenshot handoff, real creator-page preview, and action-time confirmation
• Strict post-publication verification and an atomic .publish/xhs-ledger.json
• Local parser uses only the Python standard library

Requirement

Automated publishing requires a runtime that exposes the user's Chrome session. In Codex, install and enable the Chrome control plugin/extension. If controllable Chrome is unavailable, the skill can prepare the normalized payload but must not silently switch to another browser.

Usage

Use $share-to-xhs to publish nice-talk/share/01-launch to Xiaohongshu.

Scan this project's share directory and show which Xiaohongshu posts are ready.
