The server implements three well-intentioned tools with explicit Zod schemas and error handling, but falls short of production-grade quality. Tool names follow verb_noun conventions (collect_, analyze_, generate_), descriptions are substantive (137-236 characters), and all parameters have type definitions and descriptions. However, output schemas are undocumented (tools return generic JSON without shape definitions), error messages lack actionable recovery guidance, and parameter constraints are incomplete. The tool composition is sound (three separate concerns: corpus collection, analysis, skill generation), but the interfaces do not support agent chaining patterns well, no pagination for potentially large results, and unclear what fields are returned. Security is adequate for local use but lacks audit logging and permission gates. This is solidly in the 'Fair' range: functional definitions with noticeable gaps in schema documentation and error recovery.

• Document the output schema for each tool. Include sample JSON structures or TypeScript interfaces showing the exact fields returned by collectCorpus(), analyzeCorpus(), and generateVoiceSkill(). Example: 'Returns { filesCreated: number, articlesProcessed: number, outputPath: string }'.
• Enhance error messages with recovery guidance. Example: 'Corpus directory not found at C:/dev/corpus. Check that the path exists and that a prior collect_corpus call completed. Available corpus directories: ...'
• Add numeric bounds to `max_articles`. Example: 'Maximum articles to process (1 - 10000, default: 100)'. Return an error if the value is outside this range.
• Document the directory structure and naming convention. Clarify that `corpus_dir` must be an existing directory created by a prior `collect_corpus` call, and that `corpus_name` in downstream tools must exactly match the `output_name` from corpus collection.
• Add validation and clear error messages for invalid paths. Test that `corpus_dir` exists and is readable before attempting analysis. Return: 'Corpus directory C:/invalid does not exist. To collect a corpus, call collect_corpus() with output_dir set to a writable location.'
• Document what fields are returned by `analyze_corpus` and their meaning. Indicate whether results fit in a single response or require pagination. If large, add limit/offset parameters.
• Consider adding a dry-run or preview mode to `collect_corpus` to let agents validate the sitemap and filter patterns before committing to a full crawl (reduces token waste from failed runs).
