Review Descriptor

Review the descriptor for $ARGUMENTS. If a linter name is given, find its descriptor in megalinter/descriptors/.

If a linter entry declares extends: <name>, audit the resolved definition: read megalinter/descriptors/shared/<name>.megalinter-linter.yml and apply the entry's overrides on top (shallow merge). Report gaps against the shared file when the property is common to all descriptors, against the entry when it is descriptor-specific.

For each linter entry, audit against the full property list below. Report a checklist with status for each category.

1. Identity (required)

• linter_name — present, lowercase, matches CLI executable
• linter_url — valid URL to tool docs/website
• examples — at least 2: one plain, one with config file

2. Documentation Quality

• linter_text — rich description with features, what it checks, use cases
• linter_repo — GitHub/source repository URL
• linter_rules_url — URL listing all rules/checks
• linter_rules_configuration_url — how to configure
• linter_rules_inline_disable_url — how to suppress inline
• linter_rules_ignore_config_url — how to use ignore files
• linter_spdx_license — valid SPDX ID (e.g., MIT, Apache-2.0)
• linter_speed — rated 1-5 (check if realistic)
• linter_image_url or linter_icon_png_url or linter_banner_image_url — at least one image

3. CLI Configuration

• cli_lint_mode — default mode: file, list_of_files, or project
• supported_cli_lint_modes — all modes the linter supports (must include cli_lint_mode); each listed mode gets its own success/failure test, so don't declare a mode the tool can't actually run in
• config_file_name — set if linter uses a config file
• cli_config_arg_name — set if config file is used
• cli_lint_fix_arg_name — set if linter supports auto-fix
• cli_lint_fix_remove_args — set if fix mode requires removing args (e.g., --check)
• ignore_file_name + cli_lint_ignore_arg_name — set if linter has ignore files
• Excluded directories forwarding — if project is a supported lint mode, exactly ONE mechanism must be declared: cli_lint_mode_project_exclude_arg_name (+ _arg_value template, _separator when a repeated flag overrides, _seed_values when the flag replaces built-in defaults, _config_key when it replaces a config-file list), OR the _ignore_file_* properties, OR _workspace_file_name, OR a manage_excluded_directories_config() class override. Search the internet to confirm flag semantics (path/glob/regex, anchoring, repeatability, config/defaults replacement) — see .claude/rules/descriptors.md for the trap list
• If the linter class overrides build_lint_command without calling super(), verify it applies build_project_exclude_arguments() itself in project mode
• Poison fixture present in .automation/test/<test_folder>/good/.wireit/ when forwarding is declared (and the folder is not shared with a non-forwarding project linter)
• cli_version_arg_name — set if not --version
• cli_help_arg_name — set if not --help

4. Error Parsing

• cli_lint_errors_count — set (regex_count, regex_number, regex_sum, total_lines, or sarif)
• cli_lint_errors_regex — set and matches actual linter output format

5. SARIF Support

• If linter supports SARIF: can_output_sarif: true, cli_sarif_args with {{SARIF_OUTPUT_FILE}}
• If not: confirmed that tool doesn't support SARIF output (search the internet to verify)

6. Install & Platforms

• install section with proper renovate-compatible # renovate: datasource=... comments
• Version explicitly pinned (no @latest in production)
• supported_platforms lists linux/amd64 (and linux/arm64 if applicable)
• install_override for ARM if install differs by platform

7. IDE Integration

• ide.vscode — VS Code extension listed (if one exists; search if unsure)
• ide.idea — JetBrains/IntelliJ extension listed (if available)
• Other IDEs checked: eclipse, sublime, emacs, atom, visual_studio

8. Test Fixtures

• .automation/test/<test_folder>/ exists
• Contains at least one good (clean) file
• Contains at least one bad (has errors) file
• Bad file errors match cli_lint_errors_regex pattern

9. Behavior Flags

• is_formatter — set to true if it's a formatter
• activation_rules — set if depends on env vars (e.g., style choice)
• active_only_if_file_found — set if should only run when config exists
• deprecated/disabled — correct if applicable

10. Flavor Assignment

• descriptor_flavors is appropriate for the language
• Cross-check against existing flavors in flavors/
• descriptor_flavors_exclude set if needed

Summary

After the checklist, provide:

• Missing properties that should be added (with suggested values when possible)
• Incorrect values that should be fixed
• Internet search results for any missing documentation URLs, IDE extensions, or SARIF support
