CrabTrap is an open-source HTTP/HTTPS proxy built by Brex's engineering team that sits between AI agents and the external internet, evaluating every outbound request against configurable security policies before it reaches any third-party API. It uses a two-tier evaluation system: fast deterministic static rules handle the obvious cases (block this domain, require this header), while an LLM-as-a-judge handles ambiguous requests that need semantic understanding — like determining whether a request to send an email is within scope of the current task. Built in Go with a TypeScript frontend, CrabTrap ships with a PostgreSQL-backed audit log and a web UI for policy management. It supports MITM inspection of HTTPS traffic, request/response logging, and policy versioning — making it suitable for production agentic systems where compliance or security teams need a paper trail. Version 0.0.1 was released April 17, 2026 and is MIT licensed. The problem it solves is real: as AI agents gain more autonomy and access to external APIs, the attack surface grows. A compromised or misbehaving agent that can freely call any URL is a significant risk. CrabTrap gives engineering teams a single chokepoint to enforce least-privilege access — something that's been missing from most agentic frameworks that assume a trusted execution environment.

Superpowers is an open-source agentic skills framework and software development methodology built around shell-native tooling. Created by obra (Jesse Vincent), it earned the top trending spot on GitHub today with 1,645 stars — one of the highest single-day star velocities seen in April 2026. The project defines a collection of reusable "skills" — self-contained, composable capabilities that AI coding agents can call as shell commands. The philosophy emphasizes simplicity: rather than building complex Python orchestration layers, Superpowers bets on Unix-native scripts and a clean methodology that any agent (Claude Code, Cursor, etc.) can consume without framework lock-in. What makes Superpowers compelling is its timing and positioning. As the "CLAUDE.md skills" pattern popularized by Karpathy and others takes hold, Superpowers offers a structured, opinionated approach to organizing those skills at scale. The shellcode-first design means low overhead and near-universal compatibility — any agent that can run bash can use it.
Reviewer scorecard
“This fills a gap that every production agentic system needs but almost no one has solved yet. The two-tier policy engine — static rules for speed, LLM for ambiguity — is the right architecture. The fact that Brex built and open-sourced this suggests they've already battle-tested it against real agent deployments.”
“This is exactly the tooling I didn't know I needed. The shell-native approach means zero framework lock-in — works with Claude Code, Cursor, or whatever agent comes next. Jesse Vincent has been building great dev tools for decades and this has the same clean opinionated feel.”
“v0.0.1 with 126 GitHub stars is a weekend project right now, not infrastructure you should bet your production agents on. The LLM-as-a-judge for policy evaluation is also expensive and introduces its own latency — you're adding an AI call to evaluate every AI agent call. The operational complexity of running MITM HTTPS inspection in production is non-trivial.”
“The documentation is still thin and the methodology isn't fully documented yet — this is really an early-stage release riding GitHub trending momentum. The skills ecosystem only has value once there's a critical mass of community-contributed skills, and we're not there yet.”
“Agent security tooling is where network security tooling was in the early 2000s — primitive, fragmented, and urgently needed. CrabTrap is an early bet on a category that will be worth billions once enterprises start mandating audit trails for agentic systems. Brex building this in-house and open-sourcing it is a strong signal of what production agent operators actually need.”
“Shell as the lingua franca of AI agents is an underrated bet. Unix pipelines have composed elegantly for 50 years — there's no reason that paradigm shouldn't extend to agentic skills. This could become the 'npm for agent capabilities' if the community rallies around it.”
“This is deeply in the DevOps/infrastructure lane — not something a creator or designer would ever touch directly. But if the tools you use to generate content are backed by CrabTrap-style security, you'd want that. For now, it's a ship for the engineers who configure your AI stack, a skip for everyone else.”
“As someone who wants agents to actually do things without spending three hours configuring an orchestration framework, the shell-first approach is refreshing. I can write a skill in 10 lines of bash and it just works. That accessibility matters a lot for non-engineers trying to automate their workflows.”
