Document review your team actually wants to finish.
qnop is a self-hosted, enterprise-grade document review system. Upload a document, invite reviewers — individual users or whole teams — and run a coordinated review: passages are marked up right in the browser, discussed in threads, accepted or rejected; changes produce new document versions, and the review is finalized once no open annotation remains. The goal: replace the e-mail-attachment-and-comment-spreadsheet workflow with one place where reviews are precise, accountable — and genuinely satisfying to complete.

Suzaku (朱雀) is a sigma-based threat hunting and fast forensics timeline generator for cloud logs.
Suzaku (朱雀) — the "Vermilion Bird" that rules the southern heavens above the clouds — is a threat hunting and fast forensics timeline generator for cloud logs, written in memory-safe Rust. Think of Hayabusa but for cloud logs instead of Windows event logs, with native Sigma detection for AWS CloudTrail (Azure and GCP planned).
Among thousands of cloud API calls, Suzaku finds the attacks in the noise and gives you a DFIR timeline with only the events you need — plus summaries of attacker activity (source IPs, geo-location, regions, user agents) to pivot on.
An Active Directory security-assessment toolkit in Rust: a PingCastle-class auditor that maps a domain's attack paths — scored, graphed, and MITRE-tagged — then, for authorized red-team and research use, proves those paths end-to-end.

Guard skills for coding agents, quality gates that catch AI-generated failure modes in code, tests, and docs.
Focused guard skills for coding agents: second-pass quality gates that catch the systematic failure modes of AI-generated code, tests, and docs before they ship.
Best use: let your agent do the work, then invoke the relevant guard on the diff before you present, commit, or merge it. These skills can guide writing when you explicitly ask for that, but they are strongest as reactive review passes.

Ecosystem, Frameworks, Workflows for AI coding agents.
Gentle-AI is NOT an AI agent installer. Most agents are easy to install. It is an ecosystem configurator that equips the AI coding agent(s) you already use with persistent memory, Spec-Driven Development (SDD), curated skills, MCP servers, model routing, a teaching-oriented persona, and bounded native review.
Before: "I installed Claude Code / OpenCode / Cursor, but it's just a chatbot that writes code."
After: Your agent now has memory, skills, workflow, MCP tools, and a persona that actually teaches you.
