Temporary Cloudflare Accounts for AI agents

Temporary Cloudflare Accounts for AI agents

Temporary Cloudflare Accounts for AI agents The announcement says this is "for AI agents" but (as is pretty common these days) the AI hook isn't really necessary, this is an interesting feature for everyone else as well. Short version: you can now create a Cloudflare Workers project and run this, without even creating a Cloudflare account: npx wrangler deploy --temporary Cloudflare will deploy the application to a new, ephemeral project which will stay live for 60 minutes. I had GPT-5.5 xhigh…

GitHub Actions Checkout Now Blocks Risky pull_request_target Checkouts

GitHub Actions Checkout Now Blocks Risky pull_request_target Checkouts

GitHub has released actions/checkout v7 with a new default protection aimed at one of the most persistent GitHub Actions supply chain risks: privileged workflows that check out and execute code from untrusted pull requests. The change makes actions/checkout refuse common “pwn request” patterns when workflows run under pull_request_target or certain workflow_run events. These workflows execute in the context of the base repository, giving them access to the base repo’s GITHUB_TOKEN, secrets,…

Quoting Sean Lynch

Quoting Sean Lynch

The real valuable capability MCP offers over skills/CLI is isolating the auth flow outside of the agent’s context window, and potentially out of the harness completely.

That’d still be a win. — Sean Lynch, comment on Hacker News Tags: model-context-protocol, llms, ai, generative-ai, skills

Introducing Repository Access Permissions and Custom Roles

Introducing Repository Access Permissions and Custom Roles

Socket now supports more granular access control for organizations with Custom Roles and Repository Access Permissions, giving teams a more precise way to manage who can do what, and where they can do it. Modern engineering organizations rarely map cleanly to a single security team or a single set of repositories. A user might need to review alerts for one team's repositories, manage scans for another, or support a temporary project without gaining access to the entire organization. Access…

Building RAG in Laravel: Four Ingestion Bugs That Silently Wreck Retrieval

Building RAG in Laravel: Four Ingestion Bugs That Silently Wreck Retrieval

Every Laravel RAG tutorial builds the same ingestion pipeline (chunk, embed, store) and stops the moment the agent answers on screen. None of them check whether retrieval is any good. But retrieval quality is decided at ingestion, before the model runs once, and four decisions there fail with no error, no exception, no failed test: Chunking that severs the answer mid-sentence, so answer@1 falls while source hit@1 still looks healthy. An HNSW index built with vector_l2_ops while you query with…

Datasette Apps: Host custom HTML applications inside Datasette

Datasette Apps: Host custom HTML applications inside Datasette

Today we launched a new plugin for Datasette, datasette-apps, with this launch announcement post on the Datasette project blog. That post has the what, but I'm going to expand on that a little bit here to provide the why. The TL;DR Datasette Apps are self-contained HTML+JavaScript applications that run in a tightly constrained &lt;iframe&gt; sandbox hosted on your Datasette application. They can use JavaScript to run read-only SQL queries against data in Datasette, and can run write queries too…
