Workflow

Step 0: Node version alignment (precondition)

This skill hard-depends on node-version-discipline via dependencies. Before running any tsc / type-check command, align the Node version to the project-declared version (the dependency probes the full chain .nvmrc → .node-version → .tool-versions → volta → engines.node → CI config; if none declared, it asks the user rather than guessing) per its SOP — otherwise the result is untrustworthy (false pass / false fail).

Prefix every command below with source ~/.nvm/nvm.sh && nvm use <version> >/dev/null 2>&1 && node -v && (single call — shell state is not persistent). If node-version-discipline is unavailable, install it first; do not degrade.

Step 1: Detect the Right Command

Try the following commands in priority order:

# Prefer project-configured scripts
if grep -q '"type-check"' package.json; then
    npm run type-check
elif grep -q '"check"' package.json; then
    npm run check
elif [ -f "tsconfig.json" ]; then
    npx tsc --noEmit
else
    echo "⚠️ No TypeScript configuration found"
fi

Step 2: Report Results

If the check passes:

✅ TypeScript type check passed
- Node version (declared vX): ✅ aligned (note "user-specified" if no project declaration found)

If the check fails:

❌ TypeScript type errors found:

file:xxx.ts:line:column - error description
file:yyy.tsx:line:column - error description

Total: N errors

Step 3: Propose Fixes

For each error, present the fix in this format:

### Error N: [brief description]

📍 Location: file:line

🔧 Fix:
[explain the fix approach]

Apply this fix? (wait for user confirmation)

Important: Never apply a fix without explicit user confirmation.

Step 4: Batch Fix

Once the user confirms, fix errors one by one or in batch. After each fix, re-run the type check until all errors are resolved.
