This server implements 5 LSP-based tools with reasonable naming (verb-first convention: goto_definition, find_references, hover, completion, workspace_symbols). However, critical definition gaps severely limit production readiness. All tools lack explicit output schema documentation, the code shows they return TMCPToolCallResult but the response structure is not documented for LLMs. Parameter descriptions exist but are minimal (10-30 chars each, below the 72-char baseline for param annotations). The implementation is Delphi/STDIO-only, which is a hard protocol blocker. While tool names follow good conventions and input parameters are typed, the absence of output schema docs and minimal parameter guidance means LLMs cannot plan downstream operations or understand what data will be available after each call. Error handling exists (timeout tracking, retry logic) but is not surface-documented in tool descriptions, agents cannot learn recovery paths from the tool definition alone.

• Document the output schema for each tool. Example for goto_definition: 'Returns a list of Location objects, each with {uri: string (file:// URI), range: {start: {line, character}, end: {line, character}}}. Returns empty list if definition not found.'
• Expand parameter descriptions to 60-100 chars. Example: 'uri: File URI in file:// format (e.g., file:///path/to/Main.pas). LangServer will auto-open if not already loaded. Relative URIs not supported.'
• Expand tool descriptions to 150-250 chars. Template: 'Name: What it does. When: When to use this vs related tools. Returns: What type of data (list of X, single object, empty if not found). Prerequisites: Does the file need to be open first?'
• Add explicit error guidance to tool descriptions. Example: 'If no definition found, returns empty list. If LSP server timeout (>15s), will retry once with 500ms delay. If LSP crashed, error explains how to restart.'
• For completion and workspace_symbols, document result limits (e.g., 'Returns up to 50 completions sorted by relevance. Use query parameter to filter.'). Add offset/limit params if needed.
• Document idempotence and side effects. Add to descriptions: 'This tool may auto-open the document in the LSP client if not already loaded. Repeated calls with the same parameters return identical results (idempotent).'
• Add tool annotations (readOnlyHint) to all 5 tools, they are all read-only LSP queries and LLMs should know they are safe to call speculatively without approval.
• Consider adding a 'symbols_in_file' tool to complement workspace_symbols. Agents often need to enumerate symbols in the current file before searching globally.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
