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:

1. Read ~/.claude/skills/<skill-name>/SKILL.md
2. Extract the key patterns, best practices, and pitfalls
3. Apply them to the task in sequence
4. 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.
