Server provides 6 tools with basic schemas and descriptions, but significant gaps limit production readiness. Tool names follow verb_noun convention (add_repo, find_symbol, git_blame) which is good. However, descriptions are inconsistent in depth, some are adequate (find_symbol: 115 chars), others lack actionable context (list_repos: 28 chars, below 20-char floor). Parameter descriptions exist but are sparse; many lack format/constraint details. Output schemas are not documented, LLMs cannot predict response structure. Error handling is minimal; most failures return generic strings without recovery guidance. No input validation visible; tools accept untrusted paths and symbols without sanitization, creating injection risks. Overall, this is a functional but immature implementation typical of community servers (C-grade territory).

• Add output schemas to all tool definitions. Document SymbolResult as {symbol: string, file: string, line: int, kind: string, pattern: string, repo: string} and ReferenceResult as {file: string, line: int, content: string, repo: string}. Include in tool registration so LLMs know what to expect.
• Expand list_repos description to 50-150 chars: 'List all indexed repositories with their paths and branches. Call this first to discover available repos before searching symbols or references.'
• Add input validation: validate 'path' is within allowed directories (prevent traversal), validate 'symbol' matches [a-zA-Z0-9_]+ (prevent injection), validate 'kind' against enum [function, struct, define, variable, etc.].
• Categorize errors as retryable/user-fixable/fatal. E.g., 'ctags not found' → user-fixable (install tool); 'timeout' → retryable; 'permission denied' → fatal. Return structured error with 'action' field: {error: string, action: 'install_tool'|'retry'|'contact_admin'}.
• Add constraints to parameters: 'context' (1-20, default 2), 'kind' (enum: function|struct|define|variable|macro|etc.), 'branch' (git branch name format, optional). Document in descriptions and schema.
