Five tools with clear, domain-specific names (kaeris_scan_repo, kaeris_status, kaeris_list_missing_keys, kaeris_list_languages, kaeris_add_language). All have substantive descriptions (100 - 200 chars, well above the 10-char minimum). Input schemas are present with type declarations and parameter descriptions. However, output schemas are not documented in the visible code, LLMs cannot predict what fields to expect from responses. Four tools are read-only; one (kaeris_add_language) writes files and calls an external API but lacks explicit error recovery guidance. Parameter descriptions are adequate but could be more prescriptive about formats and constraints (e.g., language code format 'de', 'fr', 'ja', 'pt-BR' is mentioned in one tool but not formalized as an enum or pattern).

• Document output schemas for all five tools. Specify field names, types, and structure (e.g., kaeris_scan_repo returns {files: [{path, language, format}], framework, base_language, target_languages}).
• Add enum constraint to target_lang parameter in kaeris_add_language. Define valid language codes (e.g., enum: ['de', 'fr', 'ja', 'pt-BR', 'es', 'zh-Hans', ...]) or a regex pattern (e.g., /^[a-z]{2}(-[A-Z]{2})?$/).
• Enhance kaeris_add_language error handling: document which errors are retryable (network timeout, rate limit) vs. fatal (invalid language code, file write permission denied). Provide recovery guidance for each.
• Add explicit path validation guidance to all file-path parameters. Clarify that paths are relative to the working directory (or absolute), and that path traversal (../) is rejected.
• Add optional limit and offset parameters to kaeris_scan_repo to allow pagination. Return total_files count so agents can iterate over large repos without overwhelming the context window.
