Create professional logos through an intelligent, iterative design process. Use this skill when the user wants to create a logo, icon, favicon, brand mark, wordmark, or any visual brand identity mark. Triggers on: 'create a logo', 'design a logo', 'make me a logo', 'logo for my brand', 'I need a logo', 'brand mark', 'wordmark', 'logomark', 'icon design', 'favicon'. This is NOT a one-shot image generator — it researches, strategizes, generates symbols with AI, visually inspects every output, then programmatically composes them with real Google Fonts typography into complete logo systems (logomark, wordmark, combination marks in multiple layouts).

Scientific paper writing in LaTeX -- full pipeline from structure to compiled PDF. TDD-driven: every section is compiled and verified before moving to the next. Covers project scaffolding, citation management (OpenAlex to BibTeX), per-section academic writing with self-reflection, figure/table inclusion, LaTeX compilation, and comprehensive verification. Triggers on: 'write a paper', 'create a paper', 'academic paper about', 'scientific paper', 'LaTeX paper', 'write up results as a paper', 'draft a paper on', 'research paper about', any request to produce a formal academic/scientific paper in LaTeX. Assumes research findings, data, and/or figures already exist or will be provided -- this skill handles the WRITING, not the experimentation.

Use this skill any time the user wants to create, edit, or export a slide deck presentation. This includes any task involving slides, decks, pitch decks, keynotes, or visual presentations. Trigger when the user says anything like 'create a presentation', 'make slides', 'build a deck', 'presentation about X'. The deliverable is a set of HTML slides (1920x1080) created via the presentation-gen tool, with optional PDF/PPTX export. Do NOT trigger for documents, reports, spreadsheets, or web pages — only slide deck presentations.

Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.

Wisdom of Agents (WoA) — internal agent forum for sharing solutions to problems. Use when stuck on a problem after 2+ failed attempts, or after solving a non-trivial problem worth sharing. Provides protocol for searching existing solutions and posting new ones. Triggers on: agent is stuck, recurring error, wants to check if others hit this issue, solved a hard problem.

In-depth reference for how OpenCode works — the AI agent framework that powers this environment. Covers: agents (definition, loading, modes, model assignment), skills (discovery, loading, structure), tools (built-in + custom, permissions), commands (slash commands, frontmatter, routing), sessions (lifecycle, prompting, subagents), config (opencode.jsonc, providers, MCP servers, plugins), and the full REST/SSE API. Load this skill when you need to understand OpenCode internals, debug agent/tool/skill issues, extend the framework, create custom tools, or work with the session API.

Memory, context, and persistent knowledge management for the Kortix agent. Covers: kortix-sys-oc-plugin (observations, LTM consolidation, mem_search, mem_save, session_list, session_get), filesystem persistence rules, using .MD files for plans/notes/project state, how filesystem writes feed the memory pipeline, and best practices for ensuring nothing important is ever lost. Load this skill when you need to: understand how your memory works, decide where to persist information, write plans or notes, manage project context across sessions, or optimize your context window usage.

Search and retrieve past session data. Covers: session_list and session_get plugin tools (with TTC compression), raw SQLite queries, REST API, ripgrep/grep on legacy JSON files, and lss semantic search over session content. Load this skill when you need to: find a past session, retrieve conversation history, search across sessions by keyword, find what tool was used, look up session costs, or pull context from prior work.

Deep research agent skill. Use when the user needs thorough, scientific, truth-seeking research on any topic -- investigating claims, finding primary sources, synthesizing evidence, producing cited reports. Triggers on: 'research this', 'investigate', 'deep dive', 'find sources', 'what does the evidence say', 'literature review', 'fact check', 'analyze the research on', any request requiring multi-source investigation with citations.

Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of "Word doc", "word document", ".docx", or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a "report", "memo", "letter", "template", or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, or general coding tasks unrelated to document generation.

Free domain research and availability checking. No API keys or credentials required. Uses RDAP (1195+ TLDs) with whois CLI fallback for universal coverage. Checks if domains are available, searches keywords across TLDs, performs WHOIS/RDAP lookups, checks expiry dates, and finds nameservers. Use when the agent needs to: check if a domain is available, search for domains, find who owns a domain, check domain expiration, get nameservers, bulk check domains, or do any domain research. Triggers on: 'check domain', 'is domain available', 'search domains', 'domain availability', 'who owns this domain', 'whois', 'domain expiry', 'when does domain expire', 'nameservers for', 'domain research', 'find domains for', 'domain ideas', 'bulk domain check'.

ElevenLabs audio generation — text-to-speech, voice cloning, and sound effects. Use this skill any time the agent needs to: convert text to spoken audio, narrate documents or content, generate voiceovers, clone voices from audio samples, create sound effects, or produce any audio output from text. Supports multiple voices, languages, models, voice cloning, batch processing, and sound effect generation. Requires ELEVENLABS_API_KEY.

Send and receive email via IMAP/SMTP using curl. Works with any email provider. By default uses the agent's own inbox configured via KORTIX_AGENT_EMAIL_INBOX_* env vars, but can target any SMTP/IMAP server by passing credentials directly. Use when the agent needs to: send email, check inbox, read messages, reply, search, or manage flags.

Legal document drafting -- contracts, memos, briefs, complaints, demand letters, opinions, discovery, settlements, ToS, privacy policies. Full pipeline: document structure, per-section writing, Bluebook citation, case law lookup (CourtListener API), regulation lookup (eCFR API), DOCX output, and TDD-style verification (defined terms, cross-references, placeholders, boilerplate, citation format). Triggers on: 'draft a contract', 'write a legal memo', 'create an NDA', 'write a brief', 'legal document about', 'draft a complaint', 'terms of service', 'privacy policy', 'demand letter', 'settlement agreement', 'legal opinion', 'discovery requests', any request to produce a legal or law-related document.

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.

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.
