Connect nodes that PROCESS items inside the loop to **Output 1 ("loop")** 2. Connect nodes that run AFTER the loop completes to **Output 0 ("done")** 3. The last processing node in the loop must connect back to the SplitInBatches node ### Common Mistake: AI assistants often connect these backwards because the logical flow (loop first, then done) doesn't match the technical indices (done=0, loop=1). `; const insertPoint = content.indexOf('## When to use'); if (insertPoint > -1) { content = content.slice(0, insertPoint) + outputGuidance + content.slice(insertPoint); } else { content = outputGuidance + '\n' + content; } } if (nodeType.includes('.if')) { const outputGuidance = ` ## Output Connection Information The IF node has TWO outputs: - **Output 0 (index 0) = "true"**: Items that match the condition - **Output 1 (index 1) = "false"**: Items that do not match the condition `; const insertPoint = content.indexOf('## Node parameters'); if (insertPoint > -1) { content = content.slice(0, insertPoint) + outputGuidance + content.slice(insertPoint); } } return content; } } exports.DocsMapper = DocsMapper; //# sourceMappingURL=docs-mapper.js.map
