I wanted to run markdown files like shell scripts. So I built an open source tool that lets you use a shebang to pipe them through Claude Code with full stdin&#x2F;stdout support.task.md:<pre><code> #!&#x2F;usr&#x2F;bin&#x2F;env claude-run

 Analyze this codebase and summarize the architecture.
</code></pre>
Then:<pre><code> chmod +x task.md

 .&#x2F;task.md
</code></pre>
These aren&#x27;t just prompts. Claude Code has tool use, so a markdown file can run shell commands, write scripts, read files, make API calls. The prompt orchestrates everything.A script that runs your tests and reports results (`run_tests.md`):<pre><code> #!&#x2F;usr&#x2F;bin&#x2F;env claude-run --permission-mode bypassPermissions

 Run .&#x2F;test&#x2F;run_tests.sh and summarize what passed and failed.
</code></pre>
Because stdin&#x2F;stdout work like any Unix program, you can chain them:<pre><code> cat data.json | .&#x2F;analyze.md &gt; results.txt

 git log -10 | .&#x2F;summarize.md

 .&#x2F;generate.md | .&#x2F;review.md &gt; final.txt
</code></pre>
Or mix them with traditional shell scripts:<pre><code> for f in logs&#x2F;\*.txt; do

 cat &quot;$f&quot; | .&#x2F;analyze.md &gt;&gt; summary.txt

 done
</code></pre>
This replaced a lot of Python glue code for us. Tasks that needed LLM orchestration libraries are now markdown files composed with standard Unix tools. Composable as building blocks, runnable as cron jobs, etc.One thing we didn&#x27;t expect is that these are more auditable (and shareable) than shell scripts. Install scripts like `curl -fsSL <a href="https:&#x2F;&#x2F;bun.com&#x2F;install" rel="nofollow">https:&#x2F;&#x2F;bun.com&#x2F;install</a> | bash` could become:<pre><code> `curl -fsSL https:&#x2F;&#x2F;bun.com&#x2F;install.md | claude-run`
</code></pre>
Where install.md says something like &quot;Detect my OS and architecture, download the right binary from GitHub releases, extract to ~&#x2F;.local&#x2F;bin, update my shell config.&quot; A normal human can actually read and verify that.The (really cool) executable markdown idea and auditability examples are from Pete Koomen (@koomen on X). As Pete says: &quot;Markdown feels increasingly important in a way I&#x27;m not sure most people have wrapped their heads around yet.&quot;We implemented it and added Unix pipe semantics. Currently works with Claude Code - hoping to support other AI coding tools too. You can also route scripts through different cloud providers (AWS Bedrock, etc.) if you want separate billing for automated jobs.GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;andisearch&#x2F;claude-switcher" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;andisearch&#x2F;claude-switcher</a>What workflows would you use this for?

Fixing a Buffer Overflow in Unix v4 Like It's 1973

I built this as a personal open-source project to explore how EU AI Act
requirements can be translated into concrete, inspectable technical checks.The core idea is local-first compliance:
– risk classification (Articles 5–15, incl. prohibited use cases)
– bias evaluation using CrowS-Pairs
– automatic Annex IV–oriented PDF reports
– no cloud services or external APIs (browser-based + Ollama)I’m especially interested in feedback on whether this kind of
technical framing of AI regulation makes sense in real-world projects.

I (17y&#x2F;o) have been developing a rocket launch simulation that allows the user to explore what it&#x27;s like launching a rocket from earth and putting it into orbit. This idea originally started as an educational simulation but as i&#x27;ve gone more down the rabbit hole the more i&#x27;ve wanted to make it realistic. The problem is that I&#x27;ve never had a formal orbital mechanics class or anything like that so I don&#x27;t know what I&#x27;m missing, what I currently have implemented is:<pre><code> Variable gravity
 Variable Atmospheric drag (US Standard Atmosphere 1976)
 Multi-stage rockets
 Closed-loop guidance &#x2F; pitch programs (works well within ranges 350km to 600km)
 Orbital prediction and thrusting options to change your orbit.
</code></pre>
The feedback I&#x27;m looking for is: UI improvements and possible future physics implementations that I can work on.Current code and physics can be found at: <a href="https:&#x2F;&#x2F;github.com&#x2F;donutTheJedi&#x2F;Rocket-Launch-Simulation" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;donutTheJedi&#x2F;Rocket-Launch-Simulation</a>

Hi HN, I built this side project earlier this week. It executes an English auction on Solana with a reserve price of 0.1 SOL. Auction winner gets control of a Codex editor. Auction losers get refunded (minus a &lt;$0.01 processing fee). The Codex agent operates in a sandbox and can only output HTML&#x2F;JS&#x2F;CSS.The project is open-source: <a href="https:&#x2F;&#x2F;github.com&#x2F;neelsomani&#x2F;the-daily-auction" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;neelsomani&#x2F;the-daily-auction</a>

Hey - I&#x27;ve been playing with LLMs since GPT-2 and recently experimented with fully generative UIs where the HTML&#x2F;Canvas are generated just-in-time.Every post on the feed( on slop&#x2F;duck&#x2F;storytime) you see is streamed and generated just-in-time with HTML and into a Canvas with Gemini 3 Flash.Comments and DMs are bidirectionally linked with a Cloudflare Workers Durable Object which is why they feel so fast. Every generated post is saved into a DO SQLite which is then served into the &quot;Following&quot; feed so it can be served quicker.This was inspired by Wikitok, a VSCode Extension I made around brainrot, and another fully generative UI site I made.
