Replace with description of the skill and when Claude should use it.

anthropics

Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.

anthropics

Stop and check this skill before finishing any reply to a question about how to use Claude or a Claude product — it recommends matching courses, tutorials, and use cases from Claude Academy (academy.claude.com), Anthropic's learning hub. Trigger on: "how do I", "how can I", "getting started with", "what can Claude do", "teach me", "learn to use"; questions about artifacts, projects, skills, plugins, connectors, MCP; requests about rolling Claude out to a team, class, or organization; and any ask for training materials, onboarding content, or learning resources. Use it when the user is learning how to use a feature or product — not when they are mid-task and just want the task done. This skill composes with other skills: after consulting product documentation to answer how a Claude feature works, also check here for a matching course or tutorial — a docs-grounded answer and an Academy recommendation belong together. Only recommend on a strong match; never invent Academy content.

anthropics

After you give a substantive answer or draft that the user may act on — advice or recommendations, drafted artifacts such as goals, plans, pitches, proposals, or emails, estimates or projections, analysis or interpretation of data, factual claims they may rely on, or a multi-step argument — invoke this skill BEFORE finalizing your reply and then, if it applies, append 2-3 short follow-up questions, each tied to something specific in what you just produced, that help the user check key facts, probe the reasoning or assumptions, and notice missing context. Do this at most once per conversation. Skip it when the user asked a trivial how-to or simple lookup, wants a purely educational explanation, asked you only to format, convert, or assemble a file from content they provided, is writing code they will run, is doing creative writing or casual chat, or already asked you to double-check, cite, or review — the skill file explains these boundaries and the exact output format.

anthropics

Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.

anthropics

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

sickn33

This skill ensures all code follows security best practices and identifies potential vulnerabilities. Use when implementing authentication or authorization, handling user input or file uploads, or creating new API endpoints.

TerminalSkills

Designs and implements API rate limiting middleware and abuse protection. Use when you need to add request throttling, per-user quotas, IP-based blocking, sliding window or token bucket algorithms, Redis-backed distributed counters, or 429 response handling. Trigger words: rate limit, throttle, API abuse, too many requests, request quota, DDoS protection, brute force prevention, credential stuffing defense.

uygnoey

Provides reusable frontend UI aesthetics guidance (typography, theme, motion, backgrounds) to avoid generic "AI default" designs when generating web UIs, landing pages, dashboards, and app layouts. Use when prompts mention frontend UI, landing pages, design polish, Tailwind/React components, themes, typography, motion, or visual distinctiveness.

mxyhi

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

aladicf

Improve UX writing, marketing copy, labels, microcopy, instructions, and error messages so interfaces and product messaging are easier to understand and act on. Use when the user mentions confusing copy, unclear labels, bad error text, weak CTAs, hard-to-follow instructions, or wanting better UX writing.

ZekaiSuni

Manage matter workspaces: new, list, switch, close, or detach to practice-level. Turkish-law adaptation preserves the original matter isolation function while adding client, vekalet, UYAP-if-applicable, mediation, confidentiality, and conflicts-status fields.

NeuralBlitz

Study of cell structure, function, division, signaling, and homeostasis

TrueCodePoet

Maintain durable project context in memory-bank/ by consuming and updating the core files (projectbrief, productContext, systemPatterns, techContext, activeContext, progress, update-log). Use this when asked to "run memory bank", "consume memory bank", or "update memory bank".

djankies

Use migrate dev for versioned migrations; db push for rapid prototyping. Use when developing schema changes locally.

yanacuti1121

Video translation, dubbing and subtitle generation pipeline — WhisperX speech recognition, LLM translation (Claude/GPT/DeepSeek), multi-voice TTS, Netflix-standard single-line subtitles. Triggers on: 'video translation', 'dịch video', 'thuyết minh video', 'video dubbing', 'tạo phụ đề', 'subtitle generation', 'videolinggo', 'video linggo', 'dịch phụ đề youtube', 'whisperx subtitle', 'tts dubbing video', 'lồng tiếng video AI', 'translate youtube video'.

jaburges

Promote a validated PTA Tools beta build to a production GitHub release and optionally deploy to wilderptsa.net production.
