  "markdown": "# Gherkin Validator\n\n- Human page: https://happytails.ai/en/developer-tools/gherkin-validator/\n- Markdown: https://happytails.ai/en/developer-tools/gherkin-validator.md\n- Structured JSON: https://happytails.ai/agents/en/developer-tools/gherkin-validator/index.json\n- Visibility: public\n\n## Tool capabilities\n\n| Property | Value |\n| --- | --- |\n| Tool ID | `gherkin-validator` |\n| Category | developer-tools |\n| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |\n| Browser execution | Use the visible action or interactive controls. |\n| Browser processing | Browser; see tool notes for network behavior. |\n| HTTP API | Not callable through HTTP. |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nValidate basic Gherkin feature structure and unresolved example placeholders locally.\n\n### Inputs and settings\n\nText input: Your text.\n\nExample or placeholder shown in the interface (not a validated fixture):\n\n```text\nType or paste your input…\n```\n\nUp to 200,000 characters. Review the settings before running.\n\nNo additional settings are declared for this tool.\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\nInput is limited to 200000 characters. Results are computed locally and exported as JSON.\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\": \"gherkin-validator\",\n  \"category\": \"developer-tools\",\n  \"built\": true,\n  \"requirements\": \"Input is limited to 200000 characters.

Review structure and placeholder issues and download the report.\n\n## Structure, not execution\n\nThe checker validates basic syntax and placeholders. It does not run step definitions or prove behavior.\n"
