Thankfully Google has some basic protection for it. I accidentally commited my google api token, as part of some OTEL trace JSON file, and within a few minutes my key was automatically locked by google, and marked as leaked (with exact link pointing where it has happened).

I had a few useful examples of this. In order to make it work you need to define your quality gates, and rather complex spec. I personally use https://github.com/probelabs/visor for creating the gates. It can be a code-review gate, or how well implementation align with the spec and etc. And basically it makes agent loop until it pass it. One of the tips, especially when using Claude Code, is explictly ask to create a "tasks", and also use subagents. For example I want to validate and re-structure all my documentation - I would ask it to create a task to research state of my docs, then after create a task per specific detail, then create a task to re-validate quality after it has finished task. You can also play around with the gates with a more simple tooling, for example https://probelabs.com/vow/

Hope it helps!

Nice one! I had my own spin on this issue as well, but from the other angle https://github.com/probelabs/maid

Getting AI to generate valid mermaid diagrams on scale extremely hard. With maid i'm hitting 100% accuracy.

Maid is basically built from scratch mermaid parser, without any dependnecies, which knows how to auto-fix common AI slop diagramming issues.

It does not implement the Auth :)

(mcp auth is terrible btw)

New comment by LeonidBugaev in "The Agent2Agent Protocol (A2A)"

LeonidBugaev — Wed, 09 Apr 2025 14:31:16 +0000

To put it simple:

A2A is for communication between the agents. MCP is how agent communicate with its tools.

Important aspect of A2A, is that it has a notion of tasks, task rediness, and etc. E.g. you can give it a task and expect completely in few days, and get notified via webhook or polling it.

For the end users for sure A2A will cause a big confusing, and can replace a lot of current MCP usage.

Hello HN!

I'm building Probe https://probeai.dev/ for a while now, and this this docs-mcp project is showcase of its capable. Giving you a local semantic search over any codebase or docs without indexing.

Feel free to ask any questions!

Nope, it is simply fresh issues with "help wanted" and "good first issue" labels.

I do maintain big OSS projects and and try to contribute as well.

However contribution experience can very bad, if you follow the path of picking the most famous objects. Good luck contributing to Node, Rust, Shadcn and etc - they do not need your contribution, their PR queue is overloaded and they can't handle it. Plus you need to get to their internal circles first, though quite complex process.

The world is much bigger. There are so many help required from the smaller but still active projects.

Just recently I raised 3 small PRs, and they reviewed the same day!

As a my respect to all the OSS community, I have build this website, which in the nutshell shows latest "help wanted" and "good first issue" issues, from all over github in the last 24 hours.

You would be amazed how many cool projects out of there looking for the help!

One of the cases when AI not needed. There is very good working algorithm to extract content from the pages, one of implementations: https://github.com/buriy/python-readability

Plus in production, with high load, Redis cluster is way more common, which kind of solve single-threaded concern.

What I really appreciate about Rails, is the strong vision, and not becoming another bloated framework for building "enterprise grade" applications. This is a 20-year-old framework, which does not afraid to radically change with time, and still being seen as Punk compared to rest

It was so heartwarming to remember my Rails story, its been 20 years ago since I started using it! https://twitter.com/buger/status/1723040883325460818

I hope so! But I also hope that I will be also able to monetise some of this movent. GoReplay dual licensed under AGPL and Commercial license. I also sell special appliance licenses.

If anyone in this thread wants to build a product based on GoReplay technology (capture network traffic directly, via AWS Traffic Mirroring or k8s), sent me message :)
