Lilith-Zero is a security runtime written in Rust that sits between your AI agent and its MCP tool servers, enforcing deterministic access control policies and blocking data exfiltration attempts before they reach the wire. It targets what it calls the "Lethal Trifecta"—the attack chain of accessing private data, incorporating untrusted content, then exfiltrating the combination—and blocks all three steps automatically. The technical stack is serious: fail-closed architecture (default-deny everything), dynamic taint tracking that marks sensitive data with session-bound tags, cryptographically signed HMAC-SHA256 audit logs, and formal verification via the Kani prover plus cargo-fuzz fuzzing infrastructure. Performance overhead is under 0.5ms at p50 with a 4MB memory footprint. It ships as a pip-installable Python SDK that auto-discovers and wraps its Rust binary. This is a Show HN project that appeared on Hacker News today and is currently at version 0.1.3 with 260 commits—small community (15 stars) but deeply engineered. As AI agents gain write access to filesystems, databases, and APIs, the absence of a policy enforcement layer becomes a serious liability. Lilith-Zero is one of the first open-source tools to treat this problem with the rigor it deserves.

Superpowers
The agentic coding methodology that makes AI agents plan before they code

Superpowers is a sophisticated agentic coding framework and software development methodology created by Jesse Vincent at Prime Radiant. Rather than giving AI agents a blank slate, it enforces a structured workflow: agents brainstorm with stakeholders, write detailed specs, break work into 2–5 minute bite-sized tasks, then execute via parallel subagents with automated code review and test-driven development baked in. The framework runs natively on Claude Code, GitHub Copilot CLI, Cursor, Gemini CLI, and other coding agents. Its 45+ composable skills — written primarily in Shell and JavaScript — cover everything from debugging and refactoring to creating new skills on the fly. Git worktrees keep branches isolated so parallel agents don't step on each other during concurrent work. With 188,000+ GitHub stars (trending today with +1,400 in a single day) and 440+ commits, Superpowers has quietly become one of the most-starred agentic methodology repos on GitHub. MIT-licensed and available through multiple plugin marketplaces, it bolts cleanly onto existing development workflows without a major toolchain change.
Reviewer scorecard
“The Kani formal verification and cargo-fuzz integration tell me this isn't just a vanity security project—it's been engineered to actually be correct. Sub-millisecond overhead means there's no reason not to run this in front of every MCP agent deployment. 15 stars seems like an embarrassing undercount given what this does.”
“If you've ever watched Claude Code spiral into confusion after three tool calls, Superpowers is the antidote. The spec-before-code workflow eliminates most context loss, and the parallel subagent model actually ships features faster than one monolithic agent thrashing around. Worth the upfront ceremony.”
“The claims are impressive but 15 GitHub stars and one maintainer is not a security tool I'd deploy in production. Security tools require adversarial testing by the community over time—not just formal verification. The fail-closed design is correct philosophically, but I'd want to see 6 months of battle-testing and independent security audits before trusting it with real agent deployments.”
“188k GitHub stars sounds impressive until you remember star farming is rampant in 2026. The methodology requires agents to ask clarifying questions upfront — great in theory, genuinely annoying when you just want a one-line bug fixed. Adds process overhead that not every team will want.”
“This is the tool that enterprise security teams will demand before they let any AI agent touch production systems. The taint tracking model is particularly elegant—once data is tagged as sensitive, it can't flow to untrusted destinations regardless of what the LLM decides to do. This is the kind of principled security primitive the agentic ecosystem desperately needs.”
“Superpowers is a glimpse of how software will be built at scale: not by individual programmers, not by lone AI agents, but by coordinated swarms of specialised subagents following deterministic specs. The methodology here may outlast any specific underlying model.”
“Way too deep in the Rust/MCP security weeds for me to evaluate or use. This is infrastructure for enterprise AI security teams—not something a content creator or indie builder will interact with directly. Worth knowing it exists; not something I'll try this week.”
“Finally a way to actually delegate an entire feature without babysitting the AI every ten minutes. The structured brainstorm phase means the agent asks dumb questions before writing code — not after — which is a huge quality-of-life improvement.”
