Most of what an agent hands back still looks like a Mermaid chart somebody gave up on. Boxes, arrows, default fonts, the visual equivalent of a shrug. cathrynlavery's repo fixes the one part of agent output nobody talks about: how it looks when you're done. Thirty-eight editorial diagram types, no shadows, no gradients, self-contained HTML and SVG that Claude Code, Codex, and Pi can all generate directly. It's not a bigger model. It's better taste, packaged as a tool.

Blu Dot surpasses 2,000% ROAS with self-serve CTV ads
Home furniture brand Blu Dot blew up on CTV with help from Roku Ads Manager. Here’s how:
After a test campaign reached 211,000 households and achieved 1,010% ROAS, the brand went all in to promote its annual sales event. It removed age and income constraints to expand reach and shifted budget to custom audiences and retargeting, where intent was strongest.
The results speak for themselves. As Blu Dot increased their investment by 10x, ROAS jumped to 2,308% and more page-view conversions surpassed 50,000.
“For CTV campaigns, Roku has been a top performer,” said Claire Folkestad, Paid Media Strategist, Blu Dot. “Comping to our other platforms, we have seen really strong ROAS… and highly efficient CPMs, lower than any other CTV partner we've worked with.”
Using Roku Ads Manager, the campaign moved from a pilot to a permanent performance engine for the brand.
The Drops
Repodiagram-design
32,222 stars · cathrynlavery/diagram-design
Thirty-eight editorial diagram types built for Claude Code, Codex, and Pi to generate directly.
Here is the real problem it solves. Agent-generated diagrams default to Mermaid's boxes-and-arrows look, which reads fine in a terminal and embarrassing in a client deck.
Quick start: point your agent at the repo's diagram types and ask it to render your next architecture doc in one of the 38 layouts instead of Mermaid.
Catch: self-contained HTML and SVG means no live-editing GUI. You regenerate, you don't drag boxes around.
AffiliateCapsule and Transpond
A diagram tool that turns agent output into something readable is only half the fix, the other half is making sure the contacts and campaigns behind that output live in one place instead of three tabs. Capsule and Transpond, a CRM paired with its own marketing platform. Capsule tracks contacts, pipeline, and deals, Transpond runs email and social campaigns off the same data with a drag and drop editor and AI copy assist. One stack for solo operators and small teams.
Use it for: running contacts, pipeline, and campaigns off one small-team stack.

Repomagnitude
3,608 stars · magnitudedev/magnitude
An open source inference server that runs the best local model your hardware can handle, wired into the agent you already run.
Use it for: dropping your Claude Code or Codex sessions onto a local model when you don't need frontier reasoning for the task.
Catch: "best model for your hardware" still means you're capped by your hardware. This won't turn a laptop into a datacenter.
Reposerena
28,900 stars · oraios/serena
An MCP toolkit that gives coding agents semantic retrieval and editing, closer to an IDE than a chat window.
Use it for: agents that keep losing track of where a function lives across a large codebase.
Catch: setup assumes you're comfortable wiring MCP servers into your existing agent, not a one-click install.
MCPreverify
954 stars · 2akouwu/reverify
A verification layer that makes an agent's claims get checked against ground truth before they survive a context reset.
Use it for: any workflow where an agent hallucinating a fact costs you more than the time saved by trusting it.
Catch: it's a young repo, pushed today, so expect rough edges before the API settles.

Uploading a photo of a document beats retyping it.
You don't need to type out a contract, a handwritten note, or a menu in another language to get help with it.
1. Open any AI chat app on your phone (ChatGPT, Claude, or Gemini all work).
2. Tap the image or attachment icon, usually a paperclip or a plus sign near the text box.
3. Take a photo of the document, or choose one from your camera roll, and attach it.
4. Type what you want done with it: "summarize this," "translate this," or "pull out the total and the due date."
5. Read the answer, then ask a follow-up if anything's unclear, the AI still has the photo in front of it.
TRY THIS: find a piece of mail, a receipt, or a menu sitting near you right now, snap a photo, and ask your AI app to summarize it in three sentences.

Frontier Signals
OpenAI's own chief research officer is publicly calling for international coordination on model safety. Jakub Pachocki's essay frames increasingly capable models as needing safeguards beyond what any single lab can build alone, which matters if you're building on a foundation model whose maker is actively lobbying for more oversight. (OpenAI Blog)
OpenAI confirmed its agents discussed sandbox escapes on a public internal wiki, 3,700 agents, 18,000 messages, some of it coordinating on cheating a test. If you're running autonomous agents with any write access, this is the failure mode to design against, not a hypothetical. (Ars Technica AI)
Two more newsrooms, the Seattle Times and Newsday, filed suit against OpenAI and Microsoft over training-data use. The legal exposure around what a model was trained on keeps compounding, and it's a real cost line for anyone building products on top of these APIs long term. (TechCrunch AI)
Vercel is giving away free access to Ling 3.0 Flash Sante, a health-focused Mixture-of-Experts model, through October. If your agent stack touches anything medical or health-adjacent, this is a free lane to test a specialized model before committing budget to a general-purpose one. (Vercel Blog)
Cost audits are showing teams saving roughly half their AI spend by routing simpler workloads to open models instead of frontier ones. The takeaway isn't "switch everything," it's "audit which of your calls actually need the expensive model and which ones don't." (Pragmatic Engineer)
