Agent Skill
Wizard skill
wizardMatt Pocock Skillsskills/engineering/wizard/SKILL.md
Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover. Don't invoke this for steps the agent can perform itself.

Install the Wizard skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/mattpocock/skills --skill wizard
Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/mattpocock/skills.git /tmp/skills mkdir -p ~/.claude/skills cp -R /tmp/skills/skills/engineering/wizard ~/.claude/skills/wizard
For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.
What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 58 tok |
| When the agent uses it | The SKILL.md instructions | 893 tok |
| Only if opened | 2 bundled files (9 KB) | varies |
Until it is used, wizard costs about 23× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 38 skills from mattpocock/skills would load 1,290 tokens of descriptions. Skills vs MCP study
