Cc Sdd New Agent skill

cc-sdd-new-agentgotalab/cc-sdd.agents/skills/cc-sdd-new-agent/SKILL.md

Add or extend coding-agent support in cc-sdd by executing the SOP in docs/cc-sdd/sop-new-agent.md end-to-end. Use when introducing a new agent, adding a subagent-capable variant, or evaluating migration of an existing supported agent to skills-based templates.

Install the Cc Sdd New Agent skill

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

npx skills add https://github.com/gotalab/cc-sdd --skill cc-sdd-new-agent

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/.agents/skills/cc-sdd-new-agent ~/.claude/skills/cc-sdd-new-agent

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	63 tok
When the agent uses it	The SKILL.md instructions	982 tok
Only if opened	3 bundled files (4 KB)	varies

Until it is used, cc-sdd-new-agent costs about 22× 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.
