Show HN: Era – Open-source local sandbox for AI agents
Just watched this video by ThePrimeagen (https://www.youtube.com/watch?v=efwDZw7l2Nk) about attackers jailbreaking Claude to run cyber attacks. The core issue: AI agents need isolation.
We built ERA to fix this – local microVM-based sandboxing for AI-generated code with hardware-level security. Think containers, but safer. Such attacks wouldn't touch your host if running in ERA.

Quick start: https://github.com/BinSquare/ERA/tree/main/era-agent/tutoria...

Show HN: Runprompt – run .prompt files from the command line
I built a single-file Python script that lets you run LLM prompts from the command line with templating, structured outputs, and the ability to chain prompts together.
When I discovered Google's Dotprompt format (frontmatter + Handlebars templates), I realized it was perfect for something I'd been wanting: treating prompts as first-class programs you can pipe together Unix-style. Google uses Dotprompt in Firebase Genkit and I wanted something simpler - just run a .prompt file directly on the command line.
Here's what it looks like:
--- model: anthropic/claude-sonnet-4-20250514 output: format: json schema: sentiment: string, positive/negative/neutral confidence: number, 0-1 score --- Analyze the sentiment of: {{STDIN}}
Running it:
cat reviews.txt | ./runprompt sentiment.prompt | jq '.sentiment'
The things I think are interesting:
* Structured output schemas: Define JSON schemas in the frontmatter using a simple `field: type, description` syntax. The LLM reliably returns valid JSON you can pipe to other tools.
* Prompt chaining: Pipe JSON output from one prompt as template variables into the next. This makes it easy to build multi-step agentic workflows as simple shell pipelines.
* Zero dependencies: It's a single Python file that uses only stdlib. Just curl it down and run it.
* Provider agnostic: Works with Anthropic, OpenAI, Google AI, and OpenRouter (which gives you access to dozens of models through one API key).
You can use it to automate things like extracting structured data from unstructured text, generating reports from logs, and building small agentic workflows without spinning up a whole framework.
Would love your feedback, and PRs are most welcome!

Show HN: MkSlides – Markdown to slides with a similar workflow to MkDocs
As a teacher, we keep our slides as markdown files in git repos and want to build these automatically so they can be viewed online (or offline if needed). To achieve this, I have created MkSlides. This tool converts all markdown in a folder to slides generated with Reveal.js. The workflow is very similar to MkDocs.
Install: `pip install mkslides`
Building slides: `mkslides build`
Live preview during editing: `mkslides serve`
Comparison with other tools like marp, slidev, ...:
- This tool is a single command and easy to integrate in CI/CD pipelines.
- It only needs Python.
- The workflow is also very similar to MkDocs, which makes it easy to combine the two in a single GitHub/GitLab repo.
- Generates an index landing page for multiple slideshows in a folder which is really convenient if you have e.g. a slideshow per chapter.
- It is lightweight.
- Everything is IaC.

Show HN: MakeSkill – The Intelligent Skill Builder for Claude
Creating high-quality skills for Claude manually is complex, requiring specific technical knowledge of the file system structure (like SKILL.md), YAML metadata configuration, and precise prompt engineering to ensure the agent behaves correctly.
MakeSkill eliminates this friction by automating the technical implementation.
Instead of writing code and configuration files from scratch, users interact with MakeSkill's AI to refine their ideas. The platform then generates the complete, optimized skill package—following all best practices—ready to be downloaded and imported directly into Claude for immediate use.
