6 Tips for Getting More Out of Opus 4.7 — From Boris Cherny

A thread of tips shared by Boris Cherny (@bcherny), creator of Claude Code, on April 16, 2026 — after dogfooding Opus 4.7 for the last few weeks.

Context

After dogfooding Opus 4.7 for a few weeks, Boris has been feeling "incredibly productive" and shared six ways to get more out of the new model — from permission automation to effort tuning to verification patterns.

---

1/ Auto Mode — No More Permission Prompts

Opus 4.7 loves doing complex, long-running tasks: deep research, refactoring code, building complex features, iterating until a performance benchmark is hit. In the past, you either had to babyset the model while it did these sorts of long tasks, or use --dangerously-skip-permissions.

Anthropic recently rolled out auto mode as a safer alternative. In this mode, permission prompts are routed to a model-based classifier that decides whether the command is safe to run:

• If it's safe, auto-approve
• If it's risky, pause and ask

This means no more babysitting while the model runs. More than that, it means you can run more Claudes in parallel — if safe, you can switch focus to the next Claude.

Auto mode is now available for Opus 4.7 for Max, Teams, and Enterprise users. Shift+Tab to cycle between Ask permissions → Plan mode → Auto mode in the CLI, or choose it from the dropdown in Desktop or VS Code.

2/ The New /fewer-permission-prompts Skill

Anthropic released a new /fewer-permission-prompts skill. It scans through your session history to find common bash and MCP commands that are safe but repeatedly prompt for permission. It then recommends a list of commands to add to your permissions allowlist.

Use this to tune up your permissions and avoid unnecessary permission prompts, especially if you don't use auto mode.

3/ Recaps

Anthropic shipped recaps earlier this week, to prep for Opus 4.7. Recaps are short summaries of what an agent did and what's next.

Very useful when returning to a long-running session after a few minutes or a few hours:

* Cogitated for 6m 27s

* recap: Fixing the post-submit transcript shift bug. The styling-flash
  part is shipped as PR #29869 (auto-merge on, posted to stamps). Next:
  I need a screen recording of the remaining horizontal rewrap on `cc -c`
  to target that separate cause. (disable recaps in /config)

Disable recaps in /config if you don't want them.

4/ Focus Mode

Boris has been loving the new focus mode in the CLI, which hides all the intermediate work to just focus on the final result. The model has reached a point where he generally trusts it to run the right commands and make the right edits. He just looks at the final result.

Use /focus to toggle on/off.

---

5/ Configure Your Effort Level

Opus 4.7 uses adaptive thinking instead of thinking budgets. To tune the model to think more or less, tune effort.

• Lower effort — faster responses and lower token usage
• Higher effort — the most intelligence and capability

The slider presents five levels: low · medium · high · xhigh · max — Speed on the left, Intelligence on the right.

6/ Give Claude a Way to Verify Its Work

Finally, make sure Claude has a way to verify its work. This has always been important — now 4.7 is 2-3x what you get out of Claude, so it's more important than ever.

Verification looks different depending on the task:

• Backend work — have Claude run your server/service to test end-to-end
• Frontend work — use the Claude Chromium extension to give Claude a way to control your browser
• Desktop apps — use Computer Use

Boris's prompts these days look like Claude do blah blah /go, where /go is a skill that:

1. Tests itself end-to-end using bash, browser, or computer use
2. Runs /simplify
3. Puts up a PR

For long-running work, verification matters even more — when you come back to a task, you know the code works.
