For mixed directories, run both and combine the results into one report. - For PDFs, Word documents, or scanned pages, extract text first and then use `has text`. For screenshots/photos where the goal is simply to hide visible carriers such as faces, screens, paper, labels, or QR codes, use `has image`. If the goal is to reason about the text content inside an image, run OCR first and then use `has text`. - Do not overwrite or delete the original files. Text commands can restore later, image masking is irreversible. - Proactively mention configurable knobs when the user intent is clear: `has text` uses repeated `--type`; `has image` uses repeated `--type`, plus `--method` and `--strength`. - If the user intent is ambiguous, start with `scan` before `hide`. - After batch scans, summarize text file count, image file count, findings by type/category, high-risk items, and the suggested next step. - If timing matters to the user, add `--timing` and report the elapsed result in plain language afterward. - For `qr_code` and `barcode`, the default mosaic strength is automatically raised based on the detection size to ensure the encoding is destroyed. The agent does not need to manually increase `--strength` for these categories. If a detection output includes `effective_strength`, report it to the user. ## Shared CLI Contract The current CLI contract is designed for agents first: - Success returns compact JSON. - Failure also returns compact JSON with `error.code` and `error.message`. - Returned path fields are absolute. - This includes `file`, `output`, `mapping_output`, and `skipped[].file`. - Invalid combinations fail fast instead of silently falling back. - Directory mode is non-recursive. Only immediate children are processed. - Batch results can include `skipped` and `skipped_count`. - Treat `skipped` entries as unprocessed files, not as clean files. Shared command layout: ```bash {baseDir}/scripts/has.sh [options] ``` Shared options can be placed before or after the subcommand. --- # Part 1: `has text` `has text` is the plaintext namespace. It supports: - `scan` - `hide` - `restore` It runs entirely on-device and uses a local `llama-server` plus the HaS text model when model inference is required. ## Core Text Concepts ### Semantic tags Anonymized text uses semantic tags such as: ```text ``` This preserves structure better than a flat `[REDACTED]` token and is the reason restored downstream LLM output can remain usable. ### Open-set types Repeated `--type` flags are open-set. They are not limited to a fixed catalog. Natural language type names such as `"person name"`, `"address"`, `"phone number"`, or `"numeric values (transaction amounts)"` are valid. ### Public/private distinction Type wording matters. For example, `"personal location"` is usually safer than `"location"` if you want to preserve public places but hide private addresses. Public/private person-name distinctions remain less stable and should not be trusted without verification. ### Multilingual support The text model supports Chinese, English, French, German, Spanish, Portuguese, Japanese, and Korean, including mixed-language text. ### Type name language Match the `--type` language to the source text language: - **Chinese text** → use Chinese type names: `--type "人名" --type "电话号码" --type "地址"` - **Non-Chinese text** (English, French, German, etc.) → use English type names: `--type "person name" --type "phone number" --type "address"` ## Text Runtime Prerequisites `has text` auto-starts a local `llama-server` when needed. - Default model path: `~/.openclaw/tools/has-anonymizer/models/has_text_model.gguf` - Override model path: `HAS_TEXT_MODEL_PATH=/abs/path/to/has_text_model.gguf` - Override parallel cap: `HAS_TEXT_MAX_PARALLEL_REQUESTS` - If HuggingFace downloads fail, see **Model Download Mirrors** below. ## Text Usage ```bash {baseDir}/scripts/has.sh text [--timing] [--verbose] [options] ``` Namespace options: | Option | Description | |--------|-------------| | `--timing` | Include `elapsed_ms` in the JSON output | | `--verbose` | Emit runtime status and progress messages to stderr | Input methods: | Method | Description | |--------|-------------| | `--text ''` | Pass text directly | | `--file ` | Read text from a file | | `--dir ` | Process immediate plaintext files in a directory | | stdin | For single-text mode when no `--text`, `--file`, or `--dir` is provided | Rules: - `--text`, `--file`, and `--dir` are mutually exclusive. - Empty `--type` values are rejected. - Directory mode only accepts batch output flags. - Single-file `hide` requires `--mapping-output`. - Single-file `restore` requires `--mapping`. - In text directory mode, `skipped` can include unprocessed files (binary, encoding, or read errors). ## `has text scan` Finds sensitive entities without replacing them. ```bash {baseDir}/scripts/has.sh text scan --type "person name" --type "phone number" --file report.txt {baseDir}/scripts/has.sh text scan --type "person name" --type "phone number" --dir ./reports/ ``` Parameters: | Parameter | Required | Description | |-----------|:--------:|-------------| | `--type` | yes | Entity type to scan for; repeat to add more | | `--text` / `--file` / `--dir` | one input | Input source | | `--max-chunk-tokens` | | Max tokens per chunk, default `5000` | | `--max-parallel-requests` | | Max scan chunks in parallel, default `4` | Output: - Single-text mode returns `{"entities": ...}` - Directory mode returns `{"results":[...],"count":N,"summary":{...}}` - Batch output may include `skipped` and `skipped_count` ## `has text hide` Replaces sensitive entities with semantic tags. ```bash {baseDir}/scripts/has.sh text hide --type "person name" --type "address" --text "John lives in Brooklyn" --mapping-output ./mapping.json {baseDir}/scripts/has.sh text hide --type "person name" --file note.txt --output ./note.anonymized.txt --mapping-output ./note.mapping.json {baseDir}/scripts/has.sh text hide --type "person name" --dir ./docs/ ``` Parameters: | Parameter | Required | Description | |-----------|:--------:|-------------| | `--type` | yes | Entity type to anonymize; repeat to add more | | `--text` / `--file` / `--dir` | one input | Input source | | `--mapping-output` | single-file: yes | Output path for generated mapping JSON | | `--output` | single-file | Output path for anonymized text | | `--mapping` | single-file | Existing mapping JSON file for incremental anonymization | | `--output-dir` | batch | Output directory for anonymized files (default: `/.has/anonymized/`) | | `--mapping-dir` | batch | Output directory for per-file mapping JSON files (default: `/mappings/`) | | `--max-chunk-tokens` | | Max tokens per chunk, default `3000` | | `--max-parallel-requests` | | Max files in parallel for `--dir`, default `4` | | `--no-tool-pair` | | Disable diff-based pair extraction; always use Model-Pair (slower but more robust) | Behavior: - Single-file mode never emits the mapping table inline. - Single-file mode returns either: - `{"text":"...","mapping_output":"/abs/path/to/map.json"}` - `{"output":"/abs/path/to/out.txt","mapping_output":"/abs/path/to/map.json"}` - Batch mode does not accept shared `--mapping`. - Mapping files are sensitive assets. Protect them. ## `has text restore` Restores anonymized text using mapping JSON. ```bash {baseDir}/scripts/has.sh text restore --mapping mapping.json --text " lives in ..." {baseDir}/scripts/has.sh text restore --mapping mapping.json --file anonymized.txt --output restored.txt {baseDir}/scripts/has.sh text restore --dir ./.has/anonymized/ --output-dir ./.has/restored/ ``` Parameters: | Parameter | Required | Description | |-----------|:--------:|-------------| | `--mapping` | single-file: yes | Mapping JSON file path | | `--text` / `--file` / `--dir` | one input | Input source | | `--output` | single-file | Output path for restored text | | `--mapping-dir` | batch | Per-file mapping directory (default: `/mappings/`) | | `--output-dir` | batch | Output directory for restored files (default: sibling `restored/` under `.has/`, or `/.has/restored/`) | | `--max-chunk-tokens` | | Max tokens per chunk when model restore is needed, default `3000` | | `--max-parallel-requests` | | Max model-backed restore chunks in parallel | Behavior: - Single-file mode returns inline `text` unless `--output` is provided. - `restore --dir` uses per-file mapping JSON files. It does not accept a shared `--mapping`. - `restore --dir` expects mapping files at `/.mapping.json` (matching the naming convention produced by `hide --dir`). ## Typical Text Workflow Anonymize text before sending it to a cloud LLM, then restore the answer: 1. `hide` to produce anonymized text plus mapping 2. send anonymized text to the cloud model **with a tag-format explanation** (see below) 3. `restore` the model response with the mapping For multi-line text, prefer file-based intermediates over shell variables. ### Prompting the cloud LLM with anonymized text When forwarding anonymized text to a cloud LLM, the agent **must** prepend a brief explanation of the tag format so the model understands and preserves the tags. Include wording equivalent to the following (adjust language to match the conversation): > The text below has been anonymized. Sensitive entities are replaced by tags in the format ``: > > - **EntityType** — the kind of entity (matches the `--type` value, e.g. `person name`, `address`, `phone number`). > - **[ID]** — a numeric identifier. The same type + same ID always refers to the **same** real-world entity (e.g. every `` is the same person; `` is a different person). > - **.Category.Attribute** — additional semantic classification of the entity. > > **Rules:** > 1. Preserve every tag exactly as-is in your response — do not modify, translate, paraphrase, omit, or expand any tag. > 2. When referring to an anonymized entity, reuse the original tag with the correct ID. > 3. Do not attempt to guess the real values behind the tags. Omitting this explanation may cause the cloud model to strip, rewrite, or misinterpret the tags, which will break the `restore` step. ## Model Download Mirrors If HuggingFace downloads fail, use these ModelScope mirrors: - text model: `https://modelscope.cn/models/TencentXuanwu/HaS_Text_0209_0.6B_Q8` - image model: `https://modelscope.cn/models/TencentXuanwu/HaS_Image_0209_FP32` --- # Part 2: `has image` `has image` is the image namespace. It supports: - `scan` - `hide` - `categories` It loads the YOLO segmentation model directly and does not require `llama-server`. ## Image Usage ```bash {baseDir}/scripts/has.sh image [--timing] [--model MODEL] [options] ``` Namespace options: | Option | Applies to | Description | |--------|------------|-------------| | `--timing` | all image commands | Include `elapsed_ms` in the JSON output | | `--model PATH` | `scan`, `hide` | Override the image model path | ## Image Privacy Categories Common categories include `biometric_face`, `id_card`, `passport`, `license_plate`, `qr_code`, `mobile_screen`, and `paper`. Use `has image categories` when you need the full catalog of 21 supported classes. `--type` accepts: - English names - Chinese names - numeric IDs - unique partial matches such as `face` Rules: - Empty `--type` values are rejected. - Ambiguous partial matches fail fast. - Omit `--type` to scan or mask all supported categories. - In image directory mode, `skipped` can include unprocessed files. ## `has image scan` Finds privacy regions without modifying the image. ```bash {baseDir}/scripts/has.sh image scan --image photo.jpg --type face --type id_card {baseDir}/scripts/has.sh image scan --dir ./photos/ --type face ``` Parameters: | Parameter | Required | Description | |-----------|:--------:|-------------| | `--image` / `--dir` | one input | Single image or batch directory | | `--type` | | Category filter; repeat to add more | | `--conf` | | Confidence threshold, default `0.25` | | `--model` | | Override image model path | Output: - Single-image mode returns `detections` and `summary` - Directory mode returns `results`, `count`, `summary`, and optional `skipped` ## `has image hide` Detects and masks privacy regions in images. ```bash {baseDir}/scripts/has.sh image hide --image photo.jpg --type face --method blur --strength 25 {baseDir}/scripts/has.sh image hide --dir ./photos/ ``` Parameters: | Parameter | Required | Description | |-----------|:--------:|-------------| | `--image` / `--dir` | one input | Single image or batch directory | | `--output` | single-image | Output image path | | `--output-dir` | batch | Output directory | | `--type` | | Category filter; repeat to add more | | `--method` | | `mosaic`, `blur`, or `fill`; default `mosaic` | | `--strength` | | Mosaic block size or blur radius; default `15` | | `--fill-color` | | Fill color for `fill`; default `#000000` | | `--conf` | | Confidence threshold; default `0.25` | | `--model` | | Override image model path | Behavior: - Refuses to overwrite the source image. - Directory mode accepts `--output-dir`, not `--output`. - For `qr_code` and `barcode` detections with `--method mosaic`, the block size is automatically raised to `max(strength, bbox_short_side // 10, 20)` to prevent the encoding from surviving pixelation. After masking, a lightweight verification confirms the code is no longer machine-readable; if it is, the strength is escalated further (up to a fill fallback). Each affected detection includes an `effective_strength` field in the output. - A cv2-based fallback supplements YOLO detection for QR codes and barcodes. When YOLO misses a code (e.g. large codes on plain backgrounds), `cv2.QRCodeDetector` and `cv2.barcode.BarcodeDetector` provide additional coverage. When YOLO misclassifies a code region as a different category (e.g. `monitor_screen`), cv2 corrects the category before `--type` filtering, so `--type qr_code` catches all QR codes regardless of YOLO's label. Corrected detections include a `"corrected_from"` field; new detections include `"cv2_fallback": true`. ## `has image categories` Lists all supported image privacy categories. ```bash {baseDir}/scripts/has.sh image categories {baseDir}/scripts/has.sh image categories --timing ``` Behavior: - Returns `{"categories":[...]}` - Supports `--timing` ## Suggested Combined Scan For a mixed workspace: 1. run `has text scan ... --dir ` for plaintext 2. run `has image scan --dir ` for images 3. merge the two JSON results into one privacy report If the user wants masking after that, use `hide` on the specific files or directories you already identified.
