Loading ToolBench
Server has 6 tools with consistent naming (verb_noun pattern: get_*, post_*, similar_*) and descriptions present for all. However, schemas are incomplete: all tools use Zod but lack explicit type declarations in the schema objects (missing 'type: "object"', 'properties', 'required' fields). Parameter descriptions are present but generic (e.g., 'The full LeetCode problem statement' repeated 5 times). No output schemas documented. Error handling is absent, tools call Claude without validation or recovery guidance. No tool annotations (readOnlyHint, etc.). Descriptions average ~120 chars, within acceptable range but lack LLM-optimized context (when to use, prerequisites, what it returns).
Takes a LeetCode problem statement and returns the recommended DSA approach, pattern name, and time/space complexity.
Takes a LeetCode problem and the user's solution code, returns time and space complexity analysis with explanation.
Takes a LeetCode problem and where the user is stuck, returns a targeted nudge without revealing the solution.
Takes a user's accepted solution and generates a structured LeetCode discussion post with approach, complexity, estimated beat %, and why it's better than brute force.
Given a LeetCode problem, returns 3-5 similar problems that reinforce the same DSA pattern.
Given a working but suboptimal solution, nudges the user toward a better approach without revealing it. Focuses on optimization, not correctness.
Schemas lack formal JSON Schema structure. Tools register Zod objects but do not declare 'type: "object"', 'properties', or 'required' fields. This prevents clients from validating inputs before calling and forces LLMs to guess parameter types.
No output schemas documented. Tools return text via Claude but do not specify what fields or structure the LLM should expect. This forces LLMs to parse unstructured text and risks hallucination.
No error handling or recovery guidance. Tools call Claude without try-catch, validation, or actionable error messages. If Claude fails or returns malformed output, the agent receives a raw error with no guidance on what to do next.

Parameter descriptions are generic and repeated. 'The full LeetCode problem statement' appears in 5 tools identically. Descriptions lack context on when to use each tool, what makes it different from similar tools, or what the LLM should expect in the response.
No tool annotations. Tools lack readOnlyHint, destructiveHint, or idempotentHint. This prevents clients from understanding which tools are safe to retry and which have side effects.
