Research, academic papers, education, and exam prep (4.5K skills)
Search PubChem by compound name, CID, or structure notation, then retrieve molecular properties, identifiers, and bioactivity records. Find compounds with similar or matching substructures, compare batches of compounds, and download structure data for cheminformatics workflows.
Build and review algorithm correctness proofs using methods such as induction, contradiction, and loop invariants. The skill helps structure each argument, explain termination, and identify gaps in a partial proof or justification.
Practice a coding interview through a timed problem, clarification, approach discussion, implementation, testing, and optimization. The skill can provide escalating hints, follow-up questions, realistic interviewer responses, and prompts to evaluate communication and performance.
Turn an algorithm problem and its solution into a clear walkthrough for study, interviews, or documentation. Explain the strategy, code, time and space costs, edge cases, common mistakes, and alternative approaches, with optional visuals or interview-style formatting.
Retrieve and parse LeetCode problems with statements, examples, constraints, hints, difficulty, tags, and related questions. Use it to gather structured material for algorithm practice and interview preparation, including code templates and available problem statistics.
Choose coding interview problems by company, difficulty, and problem-solving pattern. Track solved questions and weak areas, then get focused recommendations or a study schedule for interview preparation.
Turn algorithm execution into visual steps, showing how arrays, trees, graphs, and dynamic programming tables change. Generate formats such as ASCII, SVG, GIF, or HTML to explain concepts, inspect behavior, or support debugging.
Use the official Codeforces API to retrieve contest problems, problem sets, submissions, standings, and user rating history. It supports contest practice and progress tracking, with API rate limits and authentication where required.
Analyze dynamic programming code and transitions, then apply suitable techniques such as convex hull trick, divide and conquer, Knuth, or monotonic queue optimization. It can also reduce memory with rolling arrays or bitmask compression and explain the resulting complexity.
Organize solved CSES Problem Set problems by topic, connect them to chapters in the Competitive Programmer’s Handbook, and identify gaps. Get progress reports and suggestions for what to solve next as you build your algorithm skills.
Work with AtCoder contests and problems by fetching translated statements, difficulty ratings, editorials, and submission history. Submit solutions, join virtual contests, and review user statistics to track practice progress and identify areas to improve.
The listed concept covers coordinating web searches, synthesizing sources, forming hypotheses, and generating structured research reports. Its implementation is marked as pending, so specific workflows and capabilities are not yet described.
Answer trivia and factual questions using general knowledge, commonsense reasoning, and analogy across different subjects. The supplied material describes this skill as a stub, so its implementation details are not available.
Break a research question into independent sub-queries and dispatch 5–10 agents in parallel. The skill combines their findings, identifies agreement and conflicts, checks results against the codebase, and flags low-confidence conclusions for human review.
Query the Atlas knowledge graph through its MCP tools to inspect nodes, relationships, node and edge types, clusters, statistics, and wiki pages. Use the results to add best-practice context to systems already found by scanning real sources such as Azure, repositories, or directories.
Research public repositories for SKILL.md files and reusable workflows. It classifies projects by type and records findings, including processes and integration ideas that may be useful elsewhere.
Capture information from URLs by extracting titles, summaries, key takeaways, and quotes. Assess source credibility, classify insights, and save them as Markdown in suitable vault sections with links to related entries.
Create a personalized daily news brief using interests from a COG profile and context from its knowledge vault. It searches for recent sources, checks claims against source material and other reports, and labels each item with a confidence level.
Research topics on the web by refining search queries, filtering results, and checking key facts across sources. It synthesizes findings, evaluates source credibility, and highlights contradictions or gaps for competitive analysis, fact-checking, and trend research.
Make complex code, algorithms, and system behavior easier to understand through clear summaries, step-by-step walkthroughs, diagrams, pseudocode, and examples. This skill is useful for learning, onboarding, debugging discussions, and explaining design patterns to developers at different levels.
Searches Notion pages for a topic, combines relevant findings, and creates a structured document as a new Notion page. It can produce a brief, summary, or fuller report with links to source pages, conclusions, and suggested next steps.
Set up a paper-search MCP server through Docker MCP and add its usage guidance to a CLAUDE.md file. The server can search academic sources such as arXiv, PubMed, Semantic Scholar, and CrossRef, with tools to download and read some papers.
Work through an FPF cycle for a problem: develop competing hypotheses, check their logic and evidence, audit trust, and produce a decision record with a recommendation and rationale.
Chinese opera playwriting for the qupai (曲牌体) system — 元杂剧, 明清传奇, 昆曲, 川剧高腔, where sung text is filled into fixed tune patterns (填词) rather than built from paired lines varied by metre. Covers stage vs study (李渔 vs 吴梅/王季烈), the 清曲/剧曲 switch, the zaju branch (四折一楔子, one 宫调 and one rhyme per act, 一人主唱, 题目正名), the chuanqi branch (出, 副末开场, 南北合套, 集唐下场诗), tune-filling (格律, 前腔/换头/幺, 衬字, 务头, 尾声, 四十禁), the seventeen 宫调 and their affects, 套数, 排场 alternation, the spoken-to-sung cue, 帮腔, adaptation, and modern practice. From 李渔《闲情偶寄》, 吴梅《顾曲麈谈》《曲学通论》, 王季烈《螾庐曲谈》, 孔尚任's 凡例, 关汉卿, 汤显祖, 魏明伦. Use when writing or revising a 曲牌体 script, choosing a 宫调 for an emotion, laying out a 套数, filling one tune pattern, writing a zaju act or a chuanqi scene, cutting an old 传奇 into a playable version, writing a modern qupai opera, or judging whether a famous script's prosody may be copied. Not for 京剧/豫剧/越剧, which are the banqiang system; see sw-chinese-opera-banqiang.
