Claude Report — 2026-08-28

🚀 Anthropic Official

Claude Code v2.1.248 (Aug 27, 22:12 UTC)

Adds --restricted mode that strips built-in code-execution/WebFetch tools, confines file operations to the working directory, and blocks permission bypass. Ships a experimental.cacheTtl setting for custom prompt-cache duration, claude self-hosted-runner --client-label, an /usage-credits command for Enterprise orgs, and cross-session messaging between local sessions via new SendMessage/ListAgents tools.

• Also adds /doctor and /status diagnostics for failed server-managed settings, a /web-setup warning when the GitHub CLI token lacks the workflow scope, and assorted fixes to prompt-cache misses, session cleanup, permissions, and UI rendering.

Claude Code v2.1.250 (Aug 28, 00:49 UTC)

Ships bug fixes and reliability improvements (no further detail published in the changelog).

API changelog (Aug 27)

Beta files/skills endpoints drop their dated beta headers and return GA shapes matching the stable client.files/client.skills clients across Python, TypeScript, Go, Java, Ruby, and C# SDKs; client.beta.skills.delete() now removes a Skill and all its versions, and BetaSkill is renamed BetaContainerSkill.

• Adds personal API keys and service-account API keys in the Claude Console, acting with the linked user's or service account's permissions, auto-disabling when that account leaves the org, and scopable to one workspace or across all workspaces via admin endpoints.

anthropic-sdk-python v1.2.0 / anthropic-sdk-typescript v0.122.0 (Aug 27, ~20:30 UTC)

Both ship the beta files/skills GA-shape change above; Python fixes binary uploads on Bedrock (was signing the wrong bytes), makes the event accumulator forward-compatible with new session event types, and stops the agent toolset/memory tool from mangling file byte content; TypeScript improves DOMException handling and SSE parse-error logging.

• Companion releases bedrock-sdk v0.33.3 and aws-sdk v0.6.6 prefer environment credentials over AWS_PROFILE and fix SigV4 query-key signing.

Claude Agent SDK TypeScript v0.3.248 → v0.3.250 (Aug 27-28)

v0.3.248 adds a per-server timeout option on createSdkMcpServer({ timeout }), overriding the global MCP_TOOL_TIMEOUT; v0.3.249/250 are parity bumps tracking Claude Code v2.1.248 and v2.1.250.

Claude Agent SDK Python v0.2.146 → v0.2.147 (Aug 27-28)

Bumps the bundled Claude CLI to v2.1.248 then v2.1.250, tracking the Claude Code releases above; no independent API changes.

Model Hardware Standard research preview (Aug 27)

Introduces a shared spec, built with HHMI Janelia Research Campus, for AI agents to safely operate physical lab and manufacturing hardware: standardized device "drivers" with read/write primitives, natural-language-tagged docs that auto-generate safety-limit reference files, control via MCP/CLI/API, parallel multi-device orchestration, and autonomous error recovery. Limited to scientific labs and advanced manufacturers for now, model-agnostic.

Expanding support for scientists (Aug 27)

Opens 10,000 Claude seats for scientists for one year (free standard seats, $15/mo premium seats with 5x usage) and broadens the AI-for-Science program beyond biology to other compute-intensive fields; PIs at academic/nonprofit institutions can also apply for up to $50,000 in extra project credits.

Funding better evaluations of AI's impact on wellbeing (Aug 25)

Launches a grant program funding independent research into how AI use affects psychological wellbeing, aiming to produce measurable evaluation methods rather than anecdotal claims.

Claude Cowork built-in browser (Aug 26)

Adds a native Chromium-based browser inside the Claude Cowork desktop app (Mac/Windows/Linux) that opens in a side panel to read pages, click, type, and fill forms without a Chrome extension or personal browsing session — on by default for Enterprise/Pro/Max/Team, reversible in settings.

🔗 MCPs & Integrations

💡 Community — Workflows & Ideas

Concord (Aug 27)

MCP + CLI that lets Claude Code, Codex, and Cursor claim work items, see each other's live status, and message each other directly, aimed at preventing duplicate or conflicting edits when running multiple coding agents in parallel.

Rafter (Aug 28)

Team-shared MCP memory layer that pulls context from Drive/Jira/OneDrive-style sources into reusable prompts and skills, so agents don't re-derive the same context every session.

AgentBridge (Aug 26)

Cross-tool sync utility that keeps the same skills and MCP server configs consistent across Claude Code, Codex, and Antigravity installs.

brownspec (Aug 27)

Claude Code plugin that reads an existing repo's conventions, interviews the user about a change, and writes spec/design/task files with blast-radius analysis, plus optional regulatory profiles (152-FZ, GDPR).

claude-shipyard (Aug 27)

Plugin marketplace purpose-built for assembling and running fleets of autonomous Claude Code agents.
