# Repetition distance checker - Human page: https://happytails.ai/en/text-tools/repetition-distance-checker/ - Markdown: https://happytails.ai/en/text-tools/repetition-distance-checker.md - Structured JSON: https://happytails.ai/agents/en/text-tools/repetition-distance-checker/index.json - Visibility: public ## Tool capabilities | Property | Value | | --- | --- | | Tool ID | `repetition-distance-checker` | | Category | text-tools | | Implementation | Registered implementation. Registration alone is not a production-quality guarantee. | | Browser execution | Use the visible action or interactive controls. | | Browser processing | Browser; see tool notes for network behavior. | | HTTP API | Not callable through HTTP. | | Browser-agent interface | run_current_tool | ### Implementation notes Choose 2 to 8 consecutive words and at least 2 to 100 occurrences. Comparison ignores intervening punctuation and uses NFC normalization and the selected case setting. Overlapping occurrences remain visible. Token-start distance and tokens between phrases are distinct measures; all positions are included in the full report. Repetition is not automatically an error. Use up to 500000 text characters and 20000 word tokens. Reports allow up to 10000 matches or repeated phrase groups. JSON and CSV preserve the full report, with bounded exports up to 40 million characters and 500000 CSV records. Analysis runs locally with a 10-second timeout. Preview search and sort cover the first 200 rows; copy returns the summary. Download the full report for every row. Your text is not uploaded. ### Inputs and settings Text input: Your text. Example or placeholder shown in the interface (not a validated fixture): ```text Type or paste your input… ``` Up to 500,000 characters. Review the settings before running. | Setting | Meaning | Control type | Default | Constraints | | --- | --- | --- | --- | --- | | `phraseLength` | Words per phrase | text | "3" | min=2 max=8 step=1 | | `minimumOccurrences` | Minimum occurrences | text | "2" | min=2 max=100 step=1 | | `caseMode` | Case comparison | select | "fold" | Allowed: fold, exact | ### Browser-agent workflow 1. Open the human page in a browser that supports WebMCP. 2. Discover the interface exposed by that page; use its actual schema. 3. Select files on the page first when the tool requires files. 4. Call `run_current_tool` with valid input and settings. 5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links. Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution. ### Planning specification Choose 2 to 8 consecutive words and at least 2 to 100 occurrences. Comparison ignores intervening punctuation and uses NFC normalization and the selected case setting. Overlapping occurrences remain visible. Token-start distance and tokens between phrases are distinct measures; all positions are included in the full report. Repetition is not automatically an error. Use up to 500000 text characters and 20000 word tokens. Reports allow up to 10000 matches or repeated phrase groups. JSON and CSV preserve the full report, with bounded exports up to 40 million characters and 500000 CSV records. Analysis runs locally with a 10-second timeout. Preview search and sort cover the first 200 rows; copy returns the summary. Download the full report for every row. Your text is not uploaded. This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support. ### Complete machine-readable capability record ```json { "id": "repetition-distance-checker", "category": "text-tools", "built": true, "requirements": "Choose 2 to 8 consecutive words and at least 2 to 100 occurrences.
