Slack Code puts Claude Code, Devin and v0 in team channels
Tag an agent in a channel and it spins up a canvas with live diffs. Plus MCP write-guardrails from Cloudflare and a free wrapper that speeds up Claude Code.

Agents move into the group chat
Salesforce's Slack Code (GA, works on any Slack plan) lets you @-mention Claude Code, Devin, v0 or ChatGPT inside a channel; it opens a dedicated Code Channel, spins up an agent workspace, and renders diffs plus a working preview in a canvas the whole team can watch. Coding — and its review — now happen in the open instead of inside one person's terminal.
Guardrails on what your MCP agents can touch
Cloudflare's WriteGuard (private beta) sorts every MCP tool into four risk tiers — read-only, minimal, contained write, critical — and can pass, attribute, or block a call before its handler runs, with a scrubbed audit trail across every connected server. You wire it up in TypeScript at the MCP portal, with no changes to the underlying servers. A concrete way to stop an agent from firing a prod deploy by accident.
A free wrapper that speeds up the agent you run
Bullet plugs into your existing Claude Code or Codex subscription (or an API key, or on-device models) over OAuth and claims 30-60% faster runs — auto-picking the model and reasoning level per prompt, parallelizing reads, searches and commands, and doing targeted code search instead of embedding your whole repo. It's free and reports a top-3 SWE-bench Verified result (95.8%). Worth a weekend try if agent latency is your bottleneck.
