UltraThink Skill Chain
Compose multiple skills into a sequential pipeline. Each skill's output feeds into the next.
Usage
/ut-chain plan + scout + react + test — Build a settings page
/ut-chain debug + fix + test — Fix the auth bug
/ut-chain research + api-designer + nextjs — Design the API
How to parse $ARGUMENTS
Split on — (em dash) or --:
- Left side: skill names separated by
+
- Right side: the task description
Execution
For each skill in the chain:
- Read
~/.claude/skills/<skill-name>/SKILL.md
- Extract the key patterns, best practices, and pitfalls
- Apply them to the task in sequence
- After each skill completes its phase, summarize what was done before moving to the next
Example chain: plan + react + test
Step 1 — Plan: Read the plan skill. Create a phased implementation plan for the task. Present the plan for user approval before continuing.
Step 2 — React: Read the react skill. Implement the solution following React patterns, hooks best practices, and performance guidelines from the skill.
Step 3 — Test: Read the test skill. Generate tests following the testing patterns, verify the implementation works.
Validation
Before executing, verify each skill exists:
for skill in $(echo "SKILLS_LIST" | tr '+' '\n' | tr -d ' '); do
if [ ! -f "$HOME/.claude/skills/$skill/SKILL.md" ]; then
echo "Skill not found: $skill"
echo "Available skills: /ut-skills"
exit 1
fi
done
Show the execution plan (which skills in what order) and ask for confirmation before starting.
