  "markdown": "# Conventional commit checker\n\n- Human page: https://happytails.ai/en/developer-tools/conventional-commit-checker/\n- Markdown: https://happytails.ai/en/developer-tools/conventional-commit-checker.md\n- Structured JSON: https://happytails.ai/agents/en/developer-tools/conventional-commit-checker/index.json\n- Visibility: public\n\n## Tool capabilities\n\n| Property | Value |\n| --- | --- |\n| Tool ID | `conventional-commit-checker` |\n| Category | developer-tools |\n| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |\n| Browser execution | Automatic updates after valid input or file selection. |\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\nCheck one complete Conventional Commits 1.0 message. Scope and ! are optional; the body and footers need a blank separator. feat suggests minor, fix suggests patch, and ! or a BREAKING CHANGE footer suggests major. Other types are allowed. This is syntax and declared impact, not a review of the actual code or release policy. Runs on your device. No remote configuration, repository or credentials are queried. Up to 1,000,000 input characters; output files are limited to 4,000,000 characters each.\n\n### Inputs and settings\n\nText input: Commit message.\n\nExample or placeholder shown in the interface (not a validated fixture):\n\n```text\nfeat(search): add saved filters\n\nAllow users to reuse filter settings.\n\nRefs #42\n```\n\nPaste text to process locally. Review the supported syntax and the result before downloading. Results update as you type. Up to 1,000,000 characters.\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\nConventional Commits 1.0 structure and explicit impact rules. No repository access or automatic version bump. Runs on your device with no configuration, repository or credential lookups. Up to 1,000,000 input characters and 4,000,000 characters per output file.\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\": \"conventional-commit-checker\",\n  \"category\": \"developer-tools\",\n  \"built\": true,\n  \"requirements\": \"Conventional Commits 1.0 structure and explicit impact rules.
