Methods Claude applies on its own.
A skill teaches Claude a precise method: revision sheet, study plan, feedback, interview, app spec. It kicks in whenever your request calls for it and delivers a complete result in the first answer.

Study skills and revision
15Bibliography Formatting
Formats the bibliographic references you provide in APA 7, ISO 690 (an international referencing standard), or Vancouver style (article, book, chapter, website, thesis), with the matching in-text citation. It never invents a missing detail (DOI, pages, year) — it flags it as 'to complete' instead.
Cite Without Plagiarizing
Teaches you to cite a source (quotation marks plus reference), paraphrase honestly, and summarize without plagiarizing, with an example of a too-close vs. a correct paraphrase, and explains plagiarism and self-plagiarism. It refuses to reword a text to dodge a plagiarism detector, and explains why.
Revision Sheet
Turns a course (pasted text, PDF, notes, slides) into a structured one- to two-page revision sheet, with definitions, key ideas, examples, and self-test questions.
Anki Flashcards
Turns a course into question-answer revision cards and produces a CSV export ready to import into Anki (semicolon-separated, Front;Back;Tags columns). Follows good flashcard rules: one idea per card, short wording, cloze deletions supported.
Active PDF Reading
Builds an active-reading plan for a long document (PDF, paper, report) — broken down by section with a time estimate, key points pulled from each part, comprehension questions to test recall, and a concept map as a Mermaid mind map.
Thesis Research Question
Guides you from a starting question to a solid thesis/dissertation research question — hypotheses, thesis outline, methodology (fieldwork, corpus, interviews), and a backward-planned schedule to your submission date, with follow-up questions to dig deeper.
Feynman Technique
Coaches the Feynman technique: you explain a concept in your own words, the skill spots the gaps, unexplained jargon, and errors, then asks follow-up questions without ever giving the full explanation upfront — until you reach a simple, accurate explanation.
Essay Outline
Helps you build the outline of an essay or argumentative dissertation (outside law) — analyzing the topic's terms, reframing it, forming the question, then two or three possible outlines with their risks for this specific topic. You choose an outline and fill it with your own ideas.
Revision Schedule
Builds a backward-planned exam revision schedule from your exam dates, subjects, their weight, and your availability, applying spaced repetition, with a safety margin and one day off a week. Exports a valid .ics file you can import into Google Calendar or Outlook.
Thesis Defense Prep
Prepares an oral thesis defense — a timed outline (intro, research question, method, results, limitations, conclusion) fit to your allotted time, 15 likely committee questions ranked by difficulty, a question-by-question mock-jury drill with feedback, and tips for managing stress and time.
Cornell Notes
Restructures raw lecture notes into the Cornell method: a markdown table with a cues/questions column, a main notes column, and a summary at the bottom, plus concrete tips for taking notes live next time.
Auto Quiz
Creates multiple-choice and open questions from a course you provide, with adjustable difficulty, interactive by default (one question at a time): the correction and explanation only come after you answer, with a final score and topics to rework.
Style Proofreading
Proofreads a text you've written (spelling, grammar, syntax, punctuation, repetition, clarity) and explains each correction in a before/after/rule table, without ever changing your ideas or your argument.
Research Paper Summary
Summarizes a research paper you provide: research question, method, sample/data, results exactly as reported, limitations and contribution, with a simple critical-reading grid that separates what the paper says from your own interpretation. It never invents a figure, a result, or a reference that isn't in the paper.
Defense Slides
Builds the full storyline of a thesis defense or pitch deck — a slide-by-slide plan (headline message, content, suggested visual, timing), readability rules (one idea per slide, contrast, font size), then exports it as a Markdown outline and a ready-to-compile Marp skeleton.
Internships, apprenticeships, jobs
8Student CV
Tailors your CV to a pasted internship or job posting, one page maximum: analyzes the ad's keywords, structures profile/education/experience/projects/skills/languages/activities, rewrites it with action verbs and measurable results, then gives you an ATS-friendly text version and a final checklist.
Apprenticeship Cover Letter
Writes a cover letter and a spoken pitch for a work-study apprenticeship, highlighting the school/company schedule, dates, the degree you're working toward, and what you bring — and reminds you to check current apprenticeship hiring incentives on official sites, without ever citing a figure itself.
Internship Cover Letter
Writes an internship cover letter in three parts (you, the company; me, my profile; us, what we can do together), 250 to 350 words, tailored to the company and the pasted job posting, plus a short email version.
Professional Email
Writes a professional email to a teacher, a company, or an administration — a clear subject line, three tone variants (formal, warm, direct-and-concise), and a ready-to-send follow-up email if you need a reply.
Professional Profile
Builds an online professional profile from what you provide — a catchy headline, an about summary, sorted skills, and experience rewritten with action verbs, without ever inventing an experience or a figure.
Parcoursup Personal Statement
Helps a high schooler build their Parcoursup (France's university application platform) personal statement through targeted questions (background, interests, experience, target programme), a structure grid, and feedback on what the student wrote themselves — it never writes the text for them.
Internship Report
Coaches your internship report: gives the standard outline and expected content for each part, suggests a daily internship log method, and reviews a report you've already written to check its structure, clarity, and whether it keeps company information confidential. It never writes the report for you.
Mock Interview
Simulates an internship or apprenticeship interview interactively, one question at a time (introduction, motivation, STAR-method behavioral questions, a field-specific technical question, questions to ask the recruiter), with feedback after each answer and a final summary with three areas to improve.
Languages
5IELTS/TOEFL Writing
Marks an IELTS or TOEFL Writing essay against the public criteria (IELTS: Task Response, Coherence & Cohesion, Lexical Resource, Grammatical Range & Accuracy), gives an indicative band estimate, then rewrites two model paragraphs WITH comments to show how to improve — the essay you submit stays your own.
Language Speaking Practice
Practices spoken foreign language through a guided conversation, from CEFR level A2 to C1, one exchange at a time, with detailed final feedback (recurring errors, vocabulary to rework, pronunciation points to watch).
TOEIC Prep
Diagnoses your TOEIC level by section (Listening and Reading), generates practice mini-tests by level, builds an N-week training plan, and explains corrections point by point. It never cites a made-up official score — only indicative progress markers.
Annotated Translation
Translates a text and provides a table of annotated translation choices — false friends avoided, language registers, alternative phrasings, and their nuance.
Thematic Vocabulary
Generates vocabulary lists by theme and CEFR level, with translation, examples in context, practice exercises, and a CSV export ready to import into Anki.
Science and engineering
8Algorithm Interview Prep
Practices technical coding interviews: problem statement, clarifying questions, guidance from a brute-force approach to an optimized one, time/space complexity, edge cases, and feedback on your proposed solution.
Lab Report Structure
Builds the full structure of a science lab report (objective, equipment, protocol, data table, analysis, uncertainty, conclusion) ready to fill in with your real data, and reviews a report you've already written to flag gaps and inconsistencies.
Step-by-Step Exercise
Walks you through a math, physics, or chemistry problem without giving the answer right away: restating the problem, knowns and unknowns, the method to follow, then three increasing levels of hints, plus a check on units and whether the result makes sense. The final answer comes only if you ask for it after trying.
Measurement Uncertainty
Applies the GUM method (type A statistical uncertainty, type B non-statistical) for measurement uncertainty, propagates uncertainty (general formula and common cases: sum, product, power), and presents the result with the right number of significant figures, with a full worked example.
LaTeX Report
Provides a complete, ready-to-compile LaTeX template for a report, lab writeup, or thesis (title page, sections, formulas, tables, figures, biblatex bibliography), and debugs a pasted compile error by identifying the line and likely cause.
Python Debugging
Helps you debug a pasted Python error: reading the traceback line by line, the likely cause, a minimal test to confirm the hypothesis, then a targeted hint — never the fully fixed code, since it's your job to fix it.
Code Review
Gives a teaching-focused code review of a student project (readability, structure, tests, basic security) as a table of prioritized points (blocking / important / minor) with an explanation and a suggested fix — it never rewrites the project for you.
UML Diagrams
Generates UML diagrams (class, sequence, use case, state) in both Mermaid and PlantUML from a text description of your system, with a consistency check (associations, cardinalities, names).
Code and vibe-coding
13REST API design
Designs a project's REST API: resources, endpoints (method, path, body, status codes), errors, pagination, authentication and a ready-to-copy OpenAPI 3 excerpt in YAML.
MVP spec sheet
Turns an app idea into a one-page MVP spec (problem, users, user stories, features, data model, screens, stack, acceptance criteria) plus the first five prompts for your AI coding tool.
Project CLAUDE.md
Generates a project's CLAUDE.md and its AGENTS.md variant (the open format read by other AI coding tools): commands, architecture, conventions, rules and no-go zones.
Deploy your project
A launch plan for a static site, a Next.js/React app or a Node/Python API: the right host among Vercel, Netlify, Cloudflare Pages, GitHub Pages or Render, precise steps and a pre-launch checklist.
Git troubleshooting
From pasted git status, git log or error output, diagnoses the situation and gives the exact, safe commands to fix it, with a backup first when the operation is risky.
Read an error
Explains a pasted error or stack trace in any common language: the message line by line, the likely cause, other possible causes, a minimal test and a hint to fix it.
Developer portfolio
Builds a student developer portfolio: 3 to 6 projects presented (problem, solution, stack, result, link), a ready-to-paste GitHub profile README, a 3-line pitch and mistakes to avoid.
Vibe-coding prompts
Breaks a feature down into short, verifiable prompts for an AI coding tool: context, a plan before code, testable steps and done-when criteria, plus the pitfalls to avoid.
Project README
Writes a project's complete README (description, screenshots to add, installation, usage, configuration, tests, deployment, licence, contributing) from a description or pasted files.
Regex explained
Builds or explains a regular expression: the regex, a piece-by-piece breakdown, a table of matching and non-matching strings, and syntax variants for JavaScript, Python and PCRE.
Security audit
A prioritised security audit of a vibe-coded app (exposed secrets, RLS or Firebase rules, authentication, input validation, CORS, dependencies) as a blocking/important/minor table with fixes.
SQL coach
Turns a plain-language question into a SQL query: schema, commented query, joins and aggregates explained, results on sample data, and 3 exercises of increasing difficulty with hidden answers.
Unit test coach
A test plan for your code (normal cases, edge cases, errors) with two complete example tests in Vitest, Jest, pytest or JUnit; you write the rest and the skill reviews them.
Health
7Anatomy Mnemonics
Creates anatomy mnemonics, labeled diagrams to fill in (text description or Mermaid), and location quizzes to memorize an anatomical region.
Medical Biostatistics
Helps you pick the right statistical test and interpret results (p-value, confidence interval, RR/OR, sensitivity/specificity, PPV/NPV) for medical biostatistics, with worked exercises and detailed calculations.
EDN Clinical Case
Generates a progressive, FICTIONAL clinical case from an EDN (French national medical exams) topic, with multi-part questions, a detailed correction given only after you answer, and a scoring grid.
ECOS Station
Simulates a full, fictional ECOS station (France's standardized clinical exam, similar to the OSCE): candidate instructions, Claude plays the standardized patient and times the exchange, then gives you a scoring grid and detailed feedback.
EDN Pharmacology Sheet
Creates a pharmacology revision sheet by drug class (mechanism, indications, contraindications, side effects, major interactions, monitoring) for the EDN/ECN. Uses the medicaments connector when available and cites the BDPM (France's public drug database), otherwise flags it as 'to verify'.
Critical Appraisal
Applies a medical paper critical-appraisal grid (study type, bias, internal/external validity, level of evidence) to an article you provide, to practice for the LCA (critical literature appraisal) section of the EDN.
Semiology Sheets
Creates a semiology sheet by body system (signs, examination maneuvers, pitfalls) for you to fill in, with recall self-test questions.
Humanities and arts
5Artwork Analysis
Guides the analysis of an artwork (painting, sculpture, photograph, visual work) from an image or description you provide — identification, objective description, composition, color and light, context, and interpretation angles with the right technical vocabulary.
Literary Commentary
Coaches the French literary commentary method on a text you provide (poem, novel excerpt, play, speech) — spotting narrative voice, stylistic devices, and register, then framing the question and two possible reading angles backed by quotes from the text. You write the commentary yourself.
Philosophy Essay
Coaches the French philosophy dissertation — analyzing the topic's key notions, uncovering the paradox it hides, framing the question, then a dialectical or progressive outline with lines of argument. You write the essay yourself.
Reading Summary
Produces a reading summary (fiche de lecture) of a book (essay, novel, theoretical work) from the book, excerpts, or your reading notes — author, context, thesis or plot, structure, key concepts, quotes flagged for you to verify, critical perspective, and links to your course.
Timeline Builder
Turns a period, a history course, or a list of events into a clear timeline — a table of dates, a Mermaid timeline diagram, context for each event, causes and consequences, and a dates quiz to revise.
Student life
2Student Budget
Builds your monthly student budget as a table (income and expenses, fixed and variable), works out your margin, suggests concrete ways to save, and lists possible aid for you to double-check — housing aid, CROUS (France's student services agency) grants, regional aid, CROUS meals — without ever inventing an amount, plus a CSV export ready to import into a spreadsheet.
Student Aid & Housing
Gives you the full checklist for the French student financial aid file (DSE) for CROUS grants and housing — supporting documents to gather, the order of steps, a calendar to double-check on the official portal, and the common traps that waste time or get an application rejected.
