●CLI — Claude Code v2.1.259 landed on September 2. It is a dense release focused on org-wide configuration, unattended runs, and permissions — the most practically useful one this week●MCP — A new managedMcpServers setting lets an organization push HTTP/SSE MCP servers to every user. At the same time allowedMcpServers narrowed in scope, so an allowlist no longer filters managed servers out●HEADLESS — The new --permission-prompts none flag denies anything that would prompt, while the active permission mode, auto included, keeps making its own calls. Useful for anything you run unattended●SECURITY — Bash Read() deny rules had gaps: files passed as option values such as --ignore-revs-file=.env, and compounds like cd DIR && cat FILE, slipped past them. Both are now covered●SLACK — Claude Tag no longer judges messages one at a time. It reads the whole channel, along with its memory and your standing instructions, and is roughly 30% better at staying out of conversations●LEARN — Claude Academy is open. It is a free learning hub built on the 4D AI Fluency Framework that Anthropic uses to onboard its own team, with completion tracked in your Claude profile●CLI — Claude Code v2.1.259 landed on September 2.

Auditing Your Own Code for Required Reason API Declarations with Claude Code

Required reason codes in PrivacyInfo.xcprivacy apply to your own code, not just third-party SDKs. After a wallpaper app of mine was rejected, here is the Claude Code workflow I use to scan Swift sources and match APIs to reason codes before submission.

PII Masking for Claude API Lives or Dies on the Ledger — Restore, Encrypt, Measure

The hard part of masking PII before Claude API isn't detection — it's operating the token ledger you restore from. Encrypted storage, multi-instance sharing, and a daily leak-rate loop, with working code.

Before You Send Reviews and Crash Logs to the Claude API: A Reversible PII Masking Design

When you run App Store reviews and Crashlytics logs through the Claude API, the personal data buried in the text is unavoidable. Here is a reversible masking design that lets you trace the model's output back to the real record, plus the pitfalls I hit in production, with code.

What metadata.user_id in the Claude API Is Actually For — Designing the Abuse-Detection vs. Privacy Trade-off

The metadata.user_id field in the Messages API exists to sharpen abuse detection, but sending raw email addresses creates a privacy problem. Here is the HMAC-based stable pseudo-ID pattern I use, plus a clear set of rules for when to send it and when not to.
