Install the Implement Spec skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/mattpocock/skills --skill implement-spec
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/implement-spec ~/.claude/skills/implement-spec
For one project only, copy the folder into .claude/skills/ in that project instead. It is marked disable-model-invocation, so the agent won't pick it on its own: you run it as /implement-spec.
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 | 18 tok |
| When the agent uses it | The SKILL.md instructions | 558 tok |
| Only if opened | 1 bundled files (1 KB) | varies |
Until it is used, implement-spec costs about 76× 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
