# doctor-plus
An extended health check for Claude Code. Runs the built-in `/doctor`, then audits your workspace against the 6 then & now context-engineering shifts Anthropic shipped with the Claude 5 models.
> Anthropic cut ~80% of the Claude Code system prompt for their newest models. Most workspaces are still written for the old ones. This skill finds where yours is.
## Quick start
```bash
git clone https://github.com/robonuggets/doctor-plus
```
Copy the skill folder into your project (or your user-level skills):
```bash
cp -r doctor-plus/.claude/skills/doctor-plus <your-project>/.claude/skills/doctor-plus
```
Then in Claude Code:
```
/doctor-plus
```
## What it does
**Part 1 - the standard checkup.** Runs the built-in `claude doctor`: install health, dead weight, CLAUDE.md trimming, slow hooks.
**Part 2 - the 6 then & now shifts.** Audits your CLAUDE.md, skills, rules, and memory against the principles Anthropic now prompts by:
| # | Then | Now |
|---|---|---|
| 1 | Give Claude rules | Let Claude use judgement |
| 2 | Give Claude examples | Design interfaces |
| 3 | Put it all upfront | Use progressive disclosure |
| 4 | Repeat yourself | Simple tool descriptions |
| 5 | Memory in CLAUDE.md | Auto-memory |
| 6 | Simple specs | Rich references |
It audits the principles, not keyword patterns - and it knows safety rules (approvals, backups, destructive actions, money) are hard on purpose and never suggests softening them.
**Part 3 - report first.** One findings table with the file and passage behind every flag. Nothing changes until you approve.
