Story

The repo covers agentic workflows, hooks, skills, MCP servers, production templates and quizzes. The scale is the story. Harness configuration has accumulated enough surface area to sustain book-length reference material, which means harness engineering is becoming a documented discipline instead of tribal knowledge.

Index the agent session logs already on your disk instead of building a memory system.
deja-vu ships as an MCP server that searches your existing Claude Code, Codex, and other transcripts, so any MCP-speaking harness can query months of prior work with no re-ingestion. The corpus already exists and cost nothing to produce. Check ~/.claude/projects/ before you bu...
Agent memory consolidated into a cross-harness layer nobody owns.
claude-mem (89.3K stars) targets seven harnesses. lean-ctx (3.5K stars, Rust, 76 MCP tools) uses 60-90% token reduction as its headline metric. Wienerdog surfaced on HN August 2 offering memory plus self-improving skills for both Claude Code and Codex. All three are harness-ne...
The Code Editor Is Dead. Three Platforms Buried It in the Same Week.
Cursor 3 launched on April 2. Not an update. A full rebuild. The editor is now secondary to what they're calling an agent orchestration workspace. You can run unlimited parallel agents, locally or in the cloud, launch them from your phone or Slack or Linear, and manage them in...

Lasso Security published research demonstrating that Claude Code's --dangerously-skip-permissions flag enables indirect prompt injection via poisoned READMEs, documentation files, and MCP responses. Then they did something unusual: they released the defense alongside the attac...
Agent Plugins 1.0 went GA — and a lab outside the authoring group shipped support the same week
A spec is a press release until someone who didn't write it implements it. GitHub made Agent Plugins 1.0 generally available on August 12 across VS Code, Copilot CLI, the Copilot SDK, and the Copilot app on all plans. The spec, published August 6, was co-authored by AWS, Anysp...
Willison Documents MCP's Rough Setup in Claude, ChatGPT
The July 29 walkthrough covers the consumer chat UIs of both products, not the developer APIs or CLI harnesses where MCP is well-trodden. That summary judgment is the finding. Know that friction before you plan any distribution strategy assuming end users will attach your MCP...
