🔭 Current Focus

📈 QuantPilot — Local-first quantitative research and execution console for strategy review, market context, backtesting, and simulated/paper/live execution with risk controls.
📝 Publio — Multi-platform publishing tool for writing once and distributing everywhere.
📄 repo-brief — Generates an AI-ready brief for any codebase by scanning the repo, detecting stack and common commands, and writing lightweight context files (AGENTS.md, repo-map.md, commands.md, risk-zones.md) plus a fix mode, GitHub Action, and MCP server.
🧠 roger-skills — Curated collection of reusable skills for AI coding agents, covering commit, debug, PR review, security review, refactor, test generation, and postmortem workflows via slash commands.
🔎 dsh-searxng — SearXNG-backed search provider plugin for DeepSeek Harness (dsh), giving agents free, self-hosted, key-less web_search through the web capability seam instead of paid search APIs.
🛡️ dsh-vet — Security vetting for DeepSeek Harness (dsh) plugins: permission and supply-chain audits before install, graded via the open dsh-vet/v1 report standard.

🧭 Smart Explorer — Tree-first side-pane explorer for browsing, filtering, and manually sorting Obsidian files, built for large vaults where the default file tree falls short. Marketplace
🔍 Vault Inspector — Local-first vault maintenance scanner for broken links, orphan attachments, duplicate files, empty notes, and large files, with JSON/Markdown output for automation. Marketplace
📤 Document Exporter — Document export tool for notes, folders, and selected files, supporting PDF, DOCX, Markdown bundles, and HTML exports. Marketplace

All three plugins are listed in the Obsidian Community Plugin marketplace under rogerdigital.
