Kortix Sandbox System Architecture
The Kortix sandbox is a Docker container running Alpine Linux with a full XFCE desktop, noVNC remote access, and the OpenCode AI agent platform. This document is the definitive reference for how the system works.
Container Image
- Base:
lscr.io/linuxserver/webtop:latest(Alpine Linux + XFCE + noVNC) - Process manager: s6-overlay v3 with
s6-rc.d(NOT the olderservices.d) - Entry point:
/opt/startup.sh→exec unshare --pid --fork /init(PID namespace so s6 gets PID 1) - User:
abc(UID 1000, set viaPUID=1000). All services run asabcvias6-setuidgid abc.
Key Paths
/workspace/— Docker volume. ONLY thing that persists across restarts. All user files live here./opt/opencode/— OpenCode config: agents, tools, skills, plugins, commands,opencode.jsonc./opt/kortix-master/— Kortix Master proxy + secret store + deployer server./app/secrets/— Docker volume. Encrypted secret storage.

openalex-paper-search
Academic paper search powered by OpenAlex -- the free, open catalog of 240M+ scholarly works. Use when the user needs to find academic papers, research articles, literature for a topic, citation data, author publications, or any scholarly source. Triggers on: 'find papers on', 'academic research about', 'what studies exist', 'literature review', 'find citations', 'scholarly articles about', 'who published on', 'papers by [author]', 'highly cited papers on', any request for peer-reviewed or academic sources. Also use during deep research when you need to ground findings in academic literature. Do NOT use for general web searches -- use web-search for that.
220legal-writer
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.
64paper-creator
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.
12deep-research
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.
10memory-context-management
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.
8domain-research
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'.
