Install the Kiro Spec Design skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/gotalab/cc-sdd --skill kiro-spec-design

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/gotalab/cc-sdd.git /tmp/cc-sdd
mkdir -p ~/.claude/skills
cp -R /tmp/cc-sdd/tools/cc-sdd/templates/agents/claude-code-skills/skills/kiro-spec-design ~/.claude/skills/kiro-spec-design

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.

Until it is used, kiro-spec-design costs about 45× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 150 skills from gotalab/cc-sdd would load 3,459 tokens of descriptions. Skills vs MCP study

Checks

Our checks found nothing to flag: it follows the Agent Skills specification's naming and size guidelines and doesn't pipe downloads into a shell.

Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, WebSearch, WebFetch, Agent. The agent can use these without asking while the skill is active.
