Before AI: I moved slow, but I knew every line. Now: I move fast, and I'm auditing things I didn't write. Both ways are exhausting.

You can just do things. Built a self-hosted cora.computer for email: - auto-triages into custom labels w/ AI - marks processed as read, uncertain → Needs Review - queues archive proposals for approval Runs on Cloudflare Workers + D1 + AI Gateway (Gemma 4)

Use Google's latest OSS model Gemma-4 in Hermes or OpenClaw via @cloudflare workers AI It's seriously impressive and noticeably faster than Kimi in my testing

I got tired of reviewing PRs blind. So I built Sherpa - a Chrome extension that explains GitHub PRs as you read them. On demand. Your code never leaves your machine. New post on how it works: markphelps.me/posts/building-llm-po…

Apple finally approved my FamilyControl prod permissions. Going to finally launch Stay on TestFlight this week. Related, I migrated trystay.app to @Cloudflare with OpenNext in 5 mins from the Triangle Co. Saves $40/month.

Gave Sherpa a fresh coat of paint and now it's running on @Cloudflare Workers + Durable Objects so summaries stay synced across tabs and users in real-time

Adding devcontainer support to Flipt let me use --dangerously-skip-permissions with Claude Code. Now the agent can run wild inside the container. Can't touch my host. Mounted my skills in. Full control. Wrote about why this matters: markphelps.me/posts/running-ai-agen…

OpenClaw Mission Control update: usage graphs 1.1M tokens across 4 agents in 6 days main: ~500k 🐷 coding: ~200k social: ~30k blog: ~15k Models: opus-4-6: 45% gpt-5.2-codex: 35% MiniMax: 15% Now I know exactly where my API budget goes.

Everyone's building OpenClaw mission controls. I built one too, but with a twist: It shows you what OpenClaw hides—the raw LLM inputs, tool calls, token counts, everything. A thread 🧵

I've installed and nuked clawdbot/openclaw like 4 times now. Local linux, then VPS. Each time something broke badly enough that nuking and starting over was the only option.

I'm building an MCP gateway in Rust 🦀 Instead of loading every tool upfront, your agent gets four meta-tools: search, inspect, call, list. Progressive discovery. 50 tokens vs 18,000 for typical workflows. Useful or solving a problem that doesn't exist?

Opus is a beast at planning (and coding) but I still have it spawn parallel subagents using Sonnet 4.5 when possible because Sonnet also ships code like a machine. Save on those rate limits!

@Experian is impossible to reach when your account gets hacked. Their AI blocks you from any human help. Anyone dealt with this? WDYD?

thinking about building a simple app that tracks car maintenance + deadlines (registration, inspection, insurance renewals). i keep a spreadsheet (like a nerd) but never look at it until something's already overdue. anyone actually solved this or is everyone just vibing?

One thing I've noticed over this holiday break: I've been rapidly prototyping ideas with AI, then taking a full day to sit with them and decide if they're actually worth pursuing. And since the code is AI-generated, killing bad ideas feels completely painless.

Gemini 2.5 Flash is absurdly fast and honestly holds its own against the bigger Gemini models.. at least for UI/design work. What are your thoughts chat?

ask your ai agent to recommend 2-3 pre-commit hooks for your current project this + husky = vibe coding bliss

CodexBar by @steipete is super nice. - works with Codex, Claude Code and Gemini - open source: github.com/steipete/CodexBar this feels like the future, AI helping us build polished little apps that do one thing really well.

Day 2 of sharing my waitlist for my new iOS app www.trystay.app So far I posted on LinkedIn and pulled in 2k eyeballs. Only 23 signups, a 1% hit rate...not exactly going viral lol. Curious which channels actually move the needle for fellow indie app builders

I’m really enjoying this ‘beads’ tool to capture and manage tasks while vibe coding. It integrates really nicely with Claude code, does what it says it does and doesn’t get in your way Much better than managing TODOs in a markdown file Check it out 👇

Every time I try to use Neovim for React/Typescript/frontend work, it feels like forcing a square peg into a round hole Vscode just hits different. There’s something about it that makes coding frontend way more enjoyable than with other tools
