Mark I. The first generation.
Your personal AI assistant. Built to think, write, build, and remember.
scroll001 / Overview
CYRIX is a personal AI assistant built iteratively on Claude Code by Anthropic. It is not a single chatbot. It is a system of skills and autonomous agents that work together to handle real workflows.
The philosophy: build one thing completely before starting the next. Quality over quantity. Every skill works reliably before the next one is added.
Built by Nicky Jacobs, a SOC Analyst and aspiring Red Teamer, specifically for his workflow. Every feature exists because it was needed.
One thing done well beats ten things half-done. Every session builds on the last.
Skills handle workflows. Agents execute in isolation. Memory persists across every session.
No generic features. Every capability was added because it solved a real, specific problem.
002 / Capabilities
Drafts, rewrites, and corrects Dutch text — general, academic (APA 7th edition), and professional. Outputs formatted .docx files with auto-filled student info.
Manages an Obsidian knowledge vault end-to-end: processes inbox notes, structures them with proper frontmatter, fixes broken links, merges duplicates, and updates tags — autonomously.
Handles Git workflows step-by-step: pull, commit, push, security scan for exposed secrets, and README rewrite. Confirms before every destructive action.
Study assistant for cybersecurity certifications. Creates structured vault notes, explains concepts, tracks progress across modules and labs, and manages cheatsheets.
Fills in daily notes conversationally — intentions, appointments, learnings, rating — or adds appointments to specific dates. Integrates with the Obsidian vault.
Iterative review cycle on reports and essays. Scores 11 criteria (grammar, spelling, APA, structure, references), generates revisions, applies them, repeats — up to 3 rounds.
Builds production-grade web interfaces with distinctive aesthetics. Avoids generic AI output. Scroll-driven animations, bold typography, creative layouts. This site was built with it.
The meta-skill. Builds and audits new CYRIX skills using best practices. How CYRIX grows — each new capability starts here.
Turns a video file into a premium scroll-driven animated website with GSAP, canvas frame rendering, counter animations, and layered scroll choreography.
Documents security incidents, analyses IOCs, creates MITRE ATT&CK mappings, generates SIEM queries, and writes structured vault notes. Five dedicated actions for daily SOC work.
Manages the CYRIX project itself — updates context files, logs decisions, tracks active projects, archives old work, and keeps the system documentation in sync.
003 / Architecture
Give CYRIX a task in natural language. A skill is triggered — either by a slash command or by describing what you need.
Skills are reusable instruction sets. They guide CYRIX through a workflow step-by-step, interact with you along the way, and delegate heavy work to agents.
Agents are autonomous subprocess workers. They handle isolated, complex tasks — file creation, document processing, vault manipulation — without polluting the main conversation.
You → Skills → Agents → Files / Vault / Git / .docx
CYRIX has persistent memory across sessions. Architectural decisions, preferences, and project state are remembered automatically — so every session builds on the last.
004 / Real Workflows
CYRIX asks for topic, sources, and requirements. The opstellen-agent drafts the full introduction, formats it to APA 7th edition, and outputs a ready-to-submit .docx — student info pre-filled.
CYRIX scans all raw inbox notes, determines the correct type (fleeting, permanent, literature, project), rewrites each with proper structure and frontmatter, links to existing knowledge, and deletes originals. A full report follows.
CYRIX checks every file for exposed secrets, stages changes, writes a commit message, and pushes to GitHub — asking for confirmation at each step. The action is logged with branch, files, and result.
005 / Technology
Powered by Claude by Anthropic via the Claude Code CLI
All skills and agents are markdown-based instruction files — readable, auditable, version-controlled
No server. No database. Pure AI + local filesystem.
Extensible: adding a new skill is as simple as writing a SKILL.md file
Mark I is not the destination. It's the starting point. Every session adds something. Every skill makes the next one easier to build.
What's next: more certifications, advanced vault intelligence, deeper Git automation, and capabilities we haven't imagined yet.
