TeXFlow has 6 tools with reasonable structure and action-based naming. However, the server exhibits significant gaps: (1) Tool descriptions are overly long and often use free-form narrative instead of concise, LLM-optimized explanations. E.g., 'document' description is 800+ characters and lists 10 sub-actions, forcing the LLM to parse a complex manual rather than getting a clear intent statement. (2) Input schemas exist for all tools but lack critical metadata, parameters are typed but descriptions are often generic or missing context. E.g., 'source' parameter appears in both 'document' and 'queue' but its meaning varies wildly (BibTeX entry vs file content vs operation dict) with no disambiguation. (3) Output schemas are completely undocumented, no description of what each tool returns, what fields to expect, or how to chain results. (4) No error handling guidance. Tools return raw strings with _with_hints() appended, but no structured error classification or recovery instructions. (5) Tool composition has issues: 'queue' bundling multiple operations in one call is convenient but breaks atomic error handling, if operation 3 of 5 fails, the LLM has no way to know which ones succeeded. (6) Many tool parameters are optional with no documented defaults, creating ambiguity. E.g., 'edit' with action='insert' requires 'block_type' and 'section' but the function signature has them as None-defaulted. Scoring: Naming is solid (verb-forward, clear). Descriptions are present but too verbose and lack LLM optimization. Schemas exist but are incomplete (no output documentation). Error handling is absent. Overall: This is a C (fair/60s range) server, functional but with noticeable gaps that would require agent workarounds.

• Rewrite tool descriptions to be concise and LLM-optimized: 50-200 chars, stating WHAT (action), WHEN (use case), and OUTPUT (expected result). Move implementation details (sub-actions, examples) to parameter descriptions or inline comments, not the main docstring. Example: 'document' → 'Create, parse, or edit LaTeX documents. Use to set up new docs, ingest markdown, or manipulate structure.' (instead of 800-char manual).
• Document output schemas explicitly. Define what each tool returns as a structured object with typed fields. E.g., render(action='compile') → {pdf_path: string, size_mb: number, compiled_at: string (ISO 8601)}. This is critical for agent chaining.
• Disambiguate context-dependent parameters. For 'document' tool, split 'source' into 'bib_entry' (action=bib_add), 'file_path' (action=ingest), and 'content' (action=ingest with inline text). For 'edit' tool, ensure 'content' description clarifies meaning per action.
• Declare action parameters as enums, not free-form strings. Change 'action: str' to 'action: Literal["create", "ingest", "outline", ...]'. This prevents hallucinated sub-actions and makes self-documenting.
• Add bounds to numeric parameters. E.g., 'columns: int (1-5)', 'dpi: int (72-600)', 'position: int (0-based, max 1000)', 'page: int (1-indexed, 1-N)'. This guides LLMs and prevents API errors.
• Add error handling documentation and structured error responses. Define what errors can occur (invalid action, missing section, LaTeX compilation error, etc.) and what the LLM should do (retry? ask user? suggest alternative?). Return {success: bool, error: {code, message, recovery_hint}} instead of plain strings.
