  "content": "Bulk rename\nPreview naming rules and collisions.\nUseful next steps\nSplit file\nChunk sizes, filenames and reconstruction instructions.\nJoin files\nRequire correct ordered binary parts.\nHow to use Bulk rename\nChoose one or more files in a supported format.\nReview the settings, then choose Run Bulk rename.\nReview the result, then use Copy result or a download link when available.\nWorking with bulk rename\nArchives package files together, sometimes with compression. The best format depends on compatibility, desired size and whether passwords or additional metadata must be retained. Extracting an archive and converting it into another archive are separate tasks.\nCommon questions\nWill recompressing an archive always reduce its size?\nNo. Already compressed media and existing archives may save little or even grow slightly. Compression method and content type both affect the result.\nDoes successful extraction prove a file is safe?\nNo. An archive can contain harmful or misleading files. Extraction establishes that the contents can be read, not that those contents should be opened or executed.\nContinue your workflow:\nSplit file\n,\nJoin files\n.",

Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nPreview naming rules and collisions; operate on user-selected copies.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"bulk-rename\",\n  \"category\": \"archive-tools\",\n  \"built\": true,\n  \"requirements\": \"Preview naming rules and collisions; operate on user-selected copies.\",\n  \"implementation\": {\n    \"fields\": [\n      {\n        \"key\": \"prefix\",\n        \"label\": \"Filename prefix\",\n        \"value\": \"file-\",\n        \"type\": \"text\"\n      }\n    ],\n    \"files\": true,\n    \"multiple\": true,\n    \"input\": false,\n    \"experience\": {\n      \"automatic\": false,\n      \"single\": false,\n      \"label\": \"Your text\",\n      \"placeholder\": \"Type or paste your input…\",\n      \"help\": \"Up to 1,000,000 characters.

Review the settings, then choose Run Bulk rename.\n3. Review the result, then use Copy result or a download link when available.\n\n## Working with bulk rename\n\nArchives package files together, sometimes with compression. The best format depends on compatibility, desired size and whether passwords or additional metadata must be retained. Extracting an archive and converting it into another archive are separate tasks.\n\n## Common questions\n\n### Will recompressing an archive always reduce its size?\n\nNo. Already compressed media and existing archives may save little or even grow slightly. Compression method and content type both affect the result.\n\n### Does successful extraction prove a file is safe?\n\nNo. An archive can contain harmful or misleading files. Extraction establishes that the contents can be read, not that those contents should be opened or executed.\n\nContinue your workflow: [Split file](https://happytails.ai/en/archive-tools/split-file/), [Join files](https://happytails.ai/en/archive-tools/join-files/).\n"
