• Document the output schema for each tool as a JSON example. E.g., init_plugin should return: {"plugin_dir": "string", "created_files": ["string"], "status": "success|error", "message": "string"}. This enables agents to chain calls and extract paths for verification.
• Formalize parameter constraints using JSON Schema properties (minLength, maxLength, pattern). For plugin_name, add: "pattern": "^[a-z0-9]([a-z0-9-]*[a-z0-9])?$" and "maxLength": 50. Update descriptions to reference these constraints.
• Expand tool descriptions to include WHEN and WHY. E.g., 'Use init_plugin to scaffold a new plugin directory structure with required metadata files. Call this before adding skills or commands. Returns the path to the created .claude-plugin directory.'
• Document error conditions as structured responses. E.g., if path does not exist: {"status": "error", "code": "path_not_found", "message": "Parent directory does not exist. Create it first with mkdir -p <parent_path>.", "suggestion": "verify_path"}
• Add optional dry_run parameter to init_plugin and package_skill (defaults to false). When true, validate the operation without creating files. Agents can verify feasibility before committing side effects.
• Clarify idempotency semantics for each tool. E.g., 'If plugin directory already exists, returns error with path to existing dir (safe to retry). Does not overwrite existing files.'
• Add permission and security notes: 'This tool requires write access to the target directory. If the user lacks permissions, the tool will fail with a permission error, suggest an alternative location or request elevated privileges.'
