What it does
Doctor is an agent skill from bluzir/claude-code-design. First-run setup + health check. Verifies Chrome DevTools MCP, installs optional deps (monolith, pptxgenjs, puppeteer), creates working dirs, runs smoke test. Use on fresh clone or when things feel broken.
Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Browser testing and QA and bug reports. It works with Model Context Protocol, Chrome DevTools, Puppeteer and python-pptx. The repository describes itself as: Claude Design reproduced for Claude Code — HTML decks, prototypes, design systems, animated videos via skills + starters + Chrome DevTools MCP.
When your agent uses it
- Tasks that involve Browser testing
- Tasks that involve QA and bug reports
Example prompts
- “/doctor”
Requirements
- Node.js
- A credential in FIGMA_TOKEN
- Pre-approved tools (allowed-tools): Read, Write, Bash(claude:*), Bash(which:*), Bash(brew:*), Bash(npm:*), Bash(node:*), Bash(mkdir:*), Bash(ls:*), Bash(test:*), mcp__chrome-devtools__*
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Inventory
- Report
- Repair (with user consent)
- Smoke test
- Hint sheet
What it can do on your machine
Read from SKILL.md and the folder at commit ce68c84. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteBash(claude:*)Bash(which:*)Bash(brew:*)Bash(npm:*)Bash(node:*)Bash(mkdir:*)Bash(ls:*)Bash(test:*)
…and 1 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
ghnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
FIGMA_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Doctor loads about 931 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 195 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 195 words (~931 tokens).
“Cold-start health check + optional auto-install. Safe to run multiple times.”
