Best AI Skills for Data & Analytics in 2026: 15 Compared
Top 15 data and analytics skills for Claude Code, ranked. Stock-trading skills dominate; only 5 of 15 are general-purpose data tools.
Data & Analytics in 2026 is a category in identity crisis. The catalog has 221 skills tagged data-analytics, but when you rank by usage, 10 of the top 15 are stock-trading or finance tools — not the SQL queries, dashboards, and ETL pipelines you'd expect. The #1 skill by signal (Agent Browser, 140K) isn't even a data skill at heart; it's a browser-automation tool people use so heavily for scraping that it earned its data-analytics ranking by sheer volume. We ranked the top 15 anyway because the actual general-purpose data skills (Excel, Data Analysis, SQL Toolkit) are buried under the trading-skill avalanche, and you need a ranked editorial pass to find them.
Quick Pick
Excel / XLSX — The most-installed general-purpose data skill in the catalog (42.6K signal). Reliable formulas, dates, types, and template preservation are the four things every AI-generated spreadsheet historically broke. This one doesn't break them. If you want trading-specific picks, go to #4 (Stock Analysis); for everything else, start here.
What These Skills Actually Do
Data & Analytics skills cluster into four real patterns, three of which are dominated by trading tools because that's where individual users have direct economic motivation: (1) Market-data skills (#2 Polymarket, #4 Stock Analysis, #6–#7 stock watchers, #9–#12, #14) — pull real-time prices, fundamentals, news, and indicators from finance APIs. (2) Spreadsheet & document skills (#3 Excel/XLSX) — generate or edit workbooks programmatically, preserving formulas and formatting. (3) Database & query skills (#15 SQL Toolkit) — schema design, query writing, migrations, indexing. (4) Cross-cutting analysis (#8 Data Analysis) — query → visualize → explain pipelines. The mediocre skills in this category are thin Yahoo Finance wrappers (#10 and several #4-#7 entries do roughly the same thing). The great ones either add a meaningful interpretation layer (8-dimension scoring in #4, technical indicators in #7 and #13) or solve a structural problem nobody else covered (the Chinese-market data hubs at #11 and #12).
How We Ranked
We sorted 15 candidate skills by a composite score:
- Popularity signal — the highest of GitHub stars, install count, or ClawHub download count. Log-scaled so a 100-star skill doesn't get buried under a 100,000-star one if the smaller one is meaningfully better.
- Quality score — when set, a 0–5 rubric that breaks ties within popularity tiers. Roughly 15% of catalog skills carry a quality score today; we surface it in the comparison table when available.
The formula is identical across the entire Best-Of 2026 series, so you can compare apples to apples between categories.
The Top 15
1. Agent Browser
Skill · clawhub/agent-browser · 140.0K signal · quality unrated Browser automation with screenshots, form filling, data extraction, and web control.
The take: Wears two hats — primarily a browser-automation skill (see the dedicated comparison) — but earns its #1 data-analytics rank because the most common real-world use is scraping data to analyze it. If your data lives behind a UI rather than an API, this is the unblock. If it lives in a database, install #15 SQL Toolkit instead.
2. Polymarket
Skill · joelchance/polymarket-trade · 80.4K signal · quality unrated Query Polymarket prediction markets — odds, trending events, prices, momentum, watchlists, resolution calendar.
The take: Prediction markets are 2026's most underrated data source — they price political outcomes, sports, macro events, and tech launches with real money attached, which keeps the data honest. This skill makes the Polymarket data queryable from Claude. Worth installing even if you don't trade — it's a sentiment dataset more rigorous than Twitter.
3. Excel / XLSX
Skill · ivangdavila/excel-xlsx · 42.6K signal · quality unrated Create, inspect, and edit Excel workbooks with reliable formulas, dates, types, formatting, recalculation, and template preservation.
The take: The unsung hero of the category. Four years of AI-generated spreadsheets that silently broke formulas or corrupted date columns made everyone wary; this skill solved the corruption-and-broken-formulas problem at the library level. Install for any workflow where someone downstream is going to open the file in actual Excel.
4. Stock Analysis
Skill · clawhub/stock-analysis · 41.7K signal · quality unrated Stocks and crypto via Yahoo Finance. Portfolio management, watchlists with alerts, dividend analysis, 8-dimension scoring, viral trend detection.
The take: The most feature-complete of the Yahoo-Finance wrappers. The 8-dimension scoring is the differentiator (most wrappers just return raw data); this one adds an interpretation layer. Hot Scanner / viral trend detection is gimmicky but harmless — the core portfolio + watchlist features are solid.
5. Model Usage
Skill · steipete/model-usage · 29.9K signal · quality unrated CodexBar CLI cost-usage summary — per-model spend for Codex or Claude, full breakdown or just the current model.
The take: Pure ops analytics — "how much did my Claude usage cost yesterday?" answered in one prompt. Doesn't sound like much until you realize most developers don't actually know their own AI spend at this granularity. Install if you're a heavy Claude Code user; skip if you don't care about cost-per-model splits.
6. Stock Watcher
Skill · robin797860/stock-watcher · 24.8K signal · quality unrated Personal watchlist on Chinese A-share data (10jqka.com.cn). Add, remove, list, summarize recent performance.
The take: China-market specific (10jqka is a Chinese finance portal). If you trade Chinese A-shares, this is the data source that matters; Yahoo Finance coverage of A-shares is uneven. Less useful for US/global markets — use #4 or #10 there.
7. Stock Market Pro
Skill · kys42/stock-market-pro · 23.6K signal · quality unrated yfinance-powered: quotes, fundamentals, ASCII trends, high-resolution charts (RSI/MACD/BB/VWAP/ATR), optional web alerts.
The take: The technical-analysis pick. RSI, MACD, Bollinger Bands, VWAP, and ATR in one skill — that's the indicator set serious chartists actually use. ASCII trends in the terminal are a nice touch for quick checks without exporting to charts. Heavier than #4 if you don't use indicators; better than #4 if you do.
8. Data Analysis
Skill · ivangdavila/data-analysis · 21.9K signal · quality unrated Query databases, generate reports, automate spreadsheets, turn raw data into actionable insights.
The take: The closest thing to a general-purpose analytics skill in the top 15 — covers query → analyze → report, not just one slice. Same author as #3 Excel/XLSX, so they integrate cleanly. Pair with #15 SQL Toolkit if your data is in Postgres; pair with #3 if your output needs to land in a workbook.
9. Intelligent Stocks Screener
Skill · financial-ai-analyst/mx-stocks-screener · 17.2K signal · quality unrated Natural-language screener for A-share, HK, US stocks, funds, bonds. Technical, news, fundamental, sentiment signals. Returns CSVs.
The take: Multi-market screener — A-share, HK, US in one tool. The differentiator is the screener abstraction (filter universe → narrow → CSV), not the data source. If you want "show me US stocks with P/E < 15 and momentum in the top decile," this is the right shape. Caveat: triggers on Chinese keywords, so prompts may need bilingual phrasing.
10. Yahoo Finance
Skill · ajanraj/yahoo-finance · 16.4K signal · quality unrated Stock prices, quotes, fundamentals, earnings, options, dividends, analyst ratings via yfinance. No API key.
The take: The barebones option — just yfinance, no interpretation layer. Install this if you want to drive your own analysis logic and just need clean data access; install #4 or #7 if you want a skill that also interprets the data.
11. tushare-finance
Skill · stanleychanh/tushare-finance · 16.0K signal · quality unrated China-market data via Tushare Pro: A-share, HK, US, funds, futures, bonds. 220+ endpoints including quotes, financials, GDP/CPI macro indicators.
The take: The macro-data pick. While most stock skills focus on prices and fundamentals, this one surfaces GDP, CPI, and other macro indicators. Useful for portfolio-construction or research workflows that need to overlay market data on macro context. Requires a Tushare Pro account (free tier with daily limits, paid for higher throughput).
12. All-Market Financial Data Hub
Skill · financial-ai-analyst/mx-finance-data · 15.0K signal · quality unrated Natural-language financial-data query across A-share, HK, US, funds, bonds. Quotes, company info, valuation, financial statements. Returns XLSX.
The take: Same author as #9. While #9 is the screener, this one is the data hub — point queries against the same multi-market dataset, but without the filter-narrow workflow. Returns XLSX which pairs well with #3 Excel/XLSX downstream. Triggers on Chinese-language prompts more reliably than English.
13. T Trading
Skill · wscats/t-trading · 14.3K signal · quality unrated Vegas-channel EMA + Fibonacci-retracement structured technical analysis for A-share and crypto short-term trading.
The take: Opinionated trading methodology baked into the skill — Vegas channels + Fibonacci. If you trade with those frameworks, this saves you the manual setup; if you don't, the output will feel arbitrary. Niche by design.
14. Us Stock Analysis
Skill · veeramanikandanr48/us-stock-analysis · 14.3K signal · quality unrated US-only stock analysis: fundamentals, technical indicators, comparisons, valuation, support/resistance.
The take: US-market focused — counterpart to the China-market skills (#6, #9, #11, #12). Comparable feature set to #4 Stock Analysis but more US-specific. Pick one or the other based on your market; running both is overkill.
15. SQL Toolkit
Skill · gitgoodordietrying/sql-toolkit · 13.4K signal · quality unrated Query, design, migrate, and optimize SQL databases — SQLite, PostgreSQL, MySQL. Schema design, queries, migrations, indexing, backup/restore, slow-query debugging.
The take: The single most underrated skill on this list. It's the only general-purpose database tool in the top 15, and it's #15 by signal because retail traders outnumber backend engineers in the install metric. If you do actual data work (not just look at stocks), install this first and most of the other 14 second.

FAQ
How is this list different from the category page on aiskill.market?
The category page is a directory: every skill in the category, sortable and filterable. This list is editorial — opinionated, time-stamped (2026-05-18), and ranked. Use the directory when you know what you want; use this when you don't.
Why does the #1 pick have fewer stars than #5?
Stars are one signal among several. The composite score above also includes install counts (which reflect actual usage on aiskill.market) and the optional quality score. A skill with a smaller star count can rank higher if its installs or quality score are strong enough to offset.
Are these all free?
The skills are open source. Backend data sources vary: Yahoo Finance-based skills (#4, #7, #10, #14) are free but rate-limited; Tushare Pro (#11) has a paid tier; Polymarket (#2) is free to query but requires their API token; the China-market screeners (#9, #12) rely on third-party data sources whose terms change frequently — check before commercial use.
How do I install one?
Each linked skill page has install instructions. The fastest path is the one-line install via the aiskill.market CLI or by adding the source repo as a Claude Code plugin marketplace.
How often does this list update?
Quarterly. Stock-related skills churn slowly (the underlying data sources are stable), but new entrants in the general data space (SQL, ETL, dashboarding) ship constantly. Expect the bottom half of this ranking to shift between cycles.
Why are so many of these stock-trading skills?
Because that's where retail users have direct economic motivation. Stock skills get installed by individual investors hoping to outperform; database and ETL skills get installed by engineers who already have AI tooling at work. The install metric reflects user count, not data-analytics breadth. The ranking is accurate; it's the category that's distorted.
What's the right starter pack for general analytics work?
Two skills: #3 Excel/XLSX + #15 SQL Toolkit. That covers "I have data in a database, I want to slice it and ship a workbook." Add #8 Data Analysis if you also want narrative report generation, #1 Agent Browser if you need to scrape the data source instead of querying it.
