343 AI skills across 16 professional domains: PM (66, deepest domain), engineering (86), marketing (39), C-level (31), compliance (27), business & growth (20), legal (17) and 7 vertical advisors (fintech, healthtech, edtech, ecommerce, proptech, climate-tech, marketplace). 786 stdlib Python tools, 67 cs-* role-based agents and 7 cross-domain personas (startup-cto, growth-marketer, solo-founder, devops-engineer and more) for 74 expert identities in total. 3 compound sub-skill systems with 21 sub-skills (Playwright Pro, Self-Improving Agent, AgentHub). 26 slash commands, 4 multi-agent orchestration patterns, an MCP server, 10 ready-made role kits and 18 built-in compliance frameworks (SOC 2, ISO 13485, MDR, FDA, HIPAA, GDPR, EU AI Act, NIS2, DORA). Install any skill in one command across 11 AI assistants: Claude Code, Cursor, Codex, Gemini CLI, Copilot, Windsurf, Cline, Aider, Goose, OpenCode and ChatGPT/Claude.ai, or run it with no setup from the browser-based skill library.

A token-efficiency toolkit for AI coding agents that trims both ends of the token loop. On the input side, a deterministic compactor strips ANSI codes, drops PASS/✓ noise, dedupes repeats and truncates test, install and build output before the model reads it: about 83% fewer input tokens with 100% of the signal kept, and a failing run always passes through whole. On the output side, an always-on rule injected every turn makes the agent write right-sized code, reach for stdlib first and cut boilerplate, while never dropping validation, error handling, security or accessibility: about 49% fewer output tokens at identical test results. A single RULES.md source generates every agent's format and CI guards it against drift. Installs in one line as a Claude Code plugin that wires both ends via PostToolUse / PreToolUse hooks, or via the occam CLI for Codex, Cursor, Copilot, Windsurf and Cline. Ships /occam:review, /occam:audit and /occam:debt commands plus an occam gain ledger, with a reproducible benchmark and 12/12 reliability gates.

Provider-agnostic AI skill library for German legal practice and EU compliance. 48 areas, 103 skills: 23 substantive areas of German law (Arbeits-, Datenschutz-, Vertrags-, Miet-, Gesellschafts-, Straf-, Insolvenz-, Prozess-, Erb-, Familien-, Sozial-, Handels-, Medizin-, Versicherungs-, Baurecht and more), 5 Fachanwaltschaften (IT-Recht, Bank- und Kapitalmarktrecht, Gewerblicher Rechtsschutz, Steuer-, Verwaltungsrecht), 7 EU / cross-cutting frameworks (KI-VO, NIS2, HinSchG, LkSG, DORA, DSA/DMA, CSRD), and 13 specialty plugins covering regulated industries (Vergabe-, Umwelt-, Energie-, Außenwirtschaft/Sanktionen, AML-KYC, Transport-, Produktrecht, KI-Governance), IP and antitrust (UWG, GWB-Kartellrecht, Kapitalmarktrecht, Patentrecht) and Berufsrecht. Each skill follows a researcher → drafter → reviewer architecture in Gutachtenstil. Every statute citation links to gesetze-im-internet.de or EUR-Lex; case-law citations are explicitly marked verified or [unverifiziert]. One canonical SKILL.md per skill, installable as a native Claude Code plugin or via Gemini Gems / OpenAI Custom GPT adapters generated by a router script. Ships PII redaction, a § 203 StGB gateway-routing guide, a DSGVO/KI-VO compliance checklist, a dated verification log and a CI-tested eval harness with 1,758 fact-pattern assertions across all 103 skills. Dual-licensed Apache-2.0 OR MIT.

Crypto portfolio optimizer built for 24/7 markets, extreme volatility and fat-tailed returns. 10 optimization strategies (mean-variance, HRP, risk parity, Ledoit-Wolf shrinkage and more), 8 risk metrics, AI-powered market views via Claude, OpenAI or Perplexity, DeFi yield integration and sentiment analysis. Walk-forward backtesting to prevent overfitting, Monte Carlo stress testing with fat-tailed (Student-t) distributions, factor models and HMM regime detection. Ships as a CLI, an interactive Streamlit dashboard and a Python API (pip install orbiter-crypto), connecting to Binance, Bybit, Kraken and OKX via ccxt. 159 tests passing.

Terminal markdown reader that actually looks good. Syntax-highlighted code blocks, inline image rendering, Mermaid diagram support, GitHub-style admonitions, multi-tab navigation, full-text search, table of contents sidebar, 8 built-in themes and presentation mode. Reads files, whole directories, URLs or stdin, with a pipe-friendly plain-text mode. GFM-compliant parsing via comrak in one Rust binary with no dependencies. Installs via Homebrew, Cargo (ink-md), Scoop or a one-line script, with pre-built binaries for Linux, macOS and Windows (amd64 + arm64).
