What's new

The highlights from Anthropic's last few weeks of releases.

July 2, 2026

More detail on Fable 5's cyber safeguards and a proposed jailbreak severity framework

Anthropic published the specifics of what Fable 5's safety classifiers block versus allow across cybersecurity use cases, plus an early draft of a Cyber Jailbreak Severity (CJS) scale built with Amazon, Microsoft, and Google. A related HackerOne program now takes reports on potential Fable 5 jailbreaks.

July 1, 2026

Claude Fable 5 and Claude Mythos 5 access restored

Global access to Fable 5 returned today after a temporary suspension; Mythos 5 is back for select US organizations. Enterprise admins also gained model entitlement controls (beta) to manage which models and effort levels their users can access.

June 30, 2026

Claude Sonnet 5 launched

Anthropic's most agentic Sonnet yet, with real gains in reasoning, tool use, coding, and knowledge work over Sonnet 4.6. It's now the default model in Claude Code, ships with a native 1M-token context window, and carries promotional pricing of $2 / $10 per Mtok through August 31, 2026.

June 30, 2026

Claude Science workbench goes live

A customizable app for researchers that bundles the tools and packages scientists already use, produces auditable artifacts, and gives flexible access to compute.

June 23, 2026

Claude Tag for Slack

Team and Enterprise plans can now tag @Claude directly inside Slack threads and delegate tasks without leaving the conversation.

June 12, 2026

Edit Claude's drafts in place

Drafts written in chat or Cowork now open beside the conversation — highlight a section, describe the change, and Claude edits it right there instead of regenerating the whole document.

Get credentialed

Claude certifications

Anthropic launched its first official technical certification in March 2026 as part of the Claude Partner Network. One exam is live today, with more planned for later in 2026.

Claude Certified Architect — Foundations

Anthropic's first technical certification. Tests whether you can design and ship production-grade Claude applications at enterprise scale: agentic architecture, MCP integration, Claude Code workflows, prompt engineering, and context management. Closed-book, no AI assistance.

Delivered via Pearson VUE · online proctored or test center

Who it's for

Open to organizations in the Claude Partner Network. Solution architects, technical partners, and consultants building Claude implementations are the intended audience. The first 5,000 partner-employee exam attempts have the fee waived.

Registration starts at Anthropic Partner Academy

Retakes

Up to 4 attempts per exam in any rolling 12-month period. Wait 14 days after attempt 1, 30 days after attempt 2, and 90 days after attempt 3 before retesting.

Digital badges issued via Credly on pass

Domain weights are the most commonly reported breakdown from exam-prep sources; treat them as directional rather than official, and confirm against Anthropic Partner Academy materials before studying.

Free courses & completion certificates

Separate from the paid, proctored CCA-F exam above: anthropic.skilljar.com hosts Anthropic Academy's full catalog of free, self-paced courses. Each one issues a completion certificate — no Partner Network membership or exam fee required.

Setting up CI/CD with Git and Claude Code

Claude Code has an official GitHub Action so you can mention @claude in issues and PRs, or run it headless on a schedule. Here's the fastest path from zero to a working pipeline.

  1. Run the installer from inside Claude Code In your repo, run /install-github-app. It installs the Claude GitHub App and walks you through adding the workflow file and API key secret. Requires repo admin access.
  2. Or set it up manually Install the app from github.com/apps/claude, add ANTHROPIC_API_KEY as a repository secret, then copy a starter workflow from anthropics/claude-code-action's examples folder into .github/workflows/.
  3. Point it at a CLAUDE.md A CLAUDE.md at the repo root defines coding standards, review criteria, and project rules — Claude follows it automatically when creating PRs or responding to mentions.
  4. Trigger it Tag @claude in a PR comment or issue, or configure the workflow to run automatically on pull_request events for hands-free review on every PR.
  5. Control cost Cap --max-turns, set workflow-level timeouts, and use GitHub's concurrency controls so a runaway job doesn't burn API tokens or Actions minutes.
.github/workflows/claude.yml — respond to @claude mentions

          prompt: "Review this PR for bugs, security issues, and style."
          claude_args: "--max-turns 5"

Using Amazon Bedrock or Google Vertex AI instead of the direct API? Same action, different auth block — swap in use_bedrock: "true" or use_vertex: "true" with OIDC-based cloud credentials rather than a static API key. Full setup steps are in the Claude Code GitHub Actions docs.

Prompt smarter

Best prompting techniques

Straight from Anthropic's own prompt engineering documentation — the handful of techniques that move the needle most.

Put long documents first

Place reference material, transcripts, or code above your instructions and question, not below. This measurably improves performance across every Claude model.

Use XML tags to separate content types

Wrapping instructions, context, and input in their own tags stops Claude from blending them together.

<instructions>Summarize the risks below in 3 bullets</instructions> <context>{{document}}</context>

Set a role in the system prompt

"You are a senior security engineer reviewing this diff" focuses tone and judgment far more reliably than describing the task alone.

Ask Claude to quote before it answers

For long-document tasks, have Claude pull the relevant quotes first, then answer using only those quotes. Cuts through noise and reduces hallucination.

Don't over-specify

Only add constraints that are directly necessary. Over-engineered prompts with excessive edge-case handling tend to make Claude more rigid, not more accurate.

Give examples, not just rules

Two or three well-chosen input/output examples usually beat a paragraph of abstract instructions, especially for formatting or tone.
