Research skills

Browse reusable Agent Skills, each with a clear purpose and practical guidance.

updating-knowledge

Systematic research methodology for building comprehensive, current knowledge on any topic. Requires web_search tool. Use when questions require thorough investigation, recent developments post-cutoff, synthesis across multiple sources, or when Claude's knowledge may be outdated or incomplete. Triggered by "Research", "Investigate", "What's current on", "Latest info on", complex queries needing validation, or technical topics with recent changes.

building-github-index

Generate progressive disclosure indexes for GitHub repositories to use as Claude project knowledge. Use when setting up projects referencing external documentation, creating searchable indexes of technical blogs or knowledge bases, combining multiple repos into one index, or when user mentions "index", "github repo", "project knowledge", or "documentation reference".

bm25

Ranked content search over any text corpus using BM25 (via xhluca/bm25s). Corpus-agnostic: works on cloned repos, project knowledge stores, uploaded files/archives, and any local directory. Stateless — builds an in-memory index each invocation, no cache, no persistence. Use when you need ranked multi-word content search beyond grep, or when picking the "most relevant files for these terms" across a corpus. Triggers on "rank these documents", "search this corpus", "find content about X", "which files are most about Y", or multi-word concept queries against a known body of text.

orienting-codebases

Interactive codebase orientation for human learning. Companion to exploring-codebases (which builds Claude's understanding); this skill builds the user's understanding through guided exercises grounded in learning science. Uses the same tree-sitting + featuring pipeline but synthesizes into interactive teaching via HTML artifacts rather than analysis documents. Triggers on "orient me to this repo", "teach me this codebase", "help me understand this code", "learning orientation", or when the user wants to build genuine comprehension of an unfamiliar codebase rather than just getting work done in it.

tiling-tree

Exhaustive problem space exploration using the MIT Synthetic Neurobiology "tiling tree" method. Partitions a problem into MECE (Mutually Exclusive, Collectively Exhaustive) subsets recursively via parallel subagents, then evaluates leaf ideas against specified criteria. Use when users say "tiling tree", "tile the solution space", "exhaustively explore approaches to", "what are all the ways to", or request a MECE breakdown of a problem. Requires orchestrating-agents skill.

china-statistics-data

Find, download, and prepare official thematic statistics from the National Bureau of Statistics of China. Use this skill when the user needs Chinese statistical indicators such as GDP, population, employment, industry, agriculture, energy, environment, transport, education, census/yearbook tables, or other socio-economic data for mapping, analysis, charts, or reports.

regulation-currency-check

This skill should be used when about to quote any normative number (dimension, ratio, monetary threshold, penalty, vendor specification) from memory or from another skill in this knowledge base, when a skill's data is older than one year or carries no date, when the topic is in a high-churn regulatory domain (building code amendments, accessibility standards, green-building versions, procurement thresholds), or when a skill is marked status: unverified.

uncertainty-and-source-control

This skill should be used whenever producing a consulting answer or authoring/editing a knowledge-base skill, to control how facts are sourced and how uncertainty is expressed: it defines the source-control iron rule (never infer un-transcribed numeric values from general practice), the three certainty labels (Verified / Secondary / Unverified), the ERROR/WARNING/INFO check-output convention, the To-Verify section format, and the tone rules that prevent confidently-wrong output.

huashu-weread-advisor

微信读书高阶顾问。在底层 weread skill 的原子 API 之上，提供四类工作流：基于已读做个性化进阶推荐（advisor）、给方向规划入门到前沿的阶梯书单（path）、把零散划线想法提炼成读书笔记总结（alchemy）、做季度/年度阅读复盘并生成可发朋友圈/公众号的文章（review）。核心方法是「书架 + 笔记交叉分析」——书架揭示用户主动分类的兴趣，笔记数据揭示「真读过的」vs「只放着的」。当用户说「推荐书」「下一本读啥」「该读什么」「想搞懂 X 这个领域」「整理我的笔记」「这本书我记住了啥」「我今年读了什么」「读书复盘」「年度盘点」时触发。即使用户只是说「不知道读啥」「有没有相关的书」「帮我看看这本读完了吗」「这个领域我入门了吗」也应触发。
