SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the friction of debugging and repairing ToolUniverse tools that fail integration tests or produce incorrect results by providing a structured workflow for diagnosis, targeted fixes, and verification.

Core Features & Use Cases

  • Root-cause diagnosis: Run targeted verbose tests and inspect API responses, headers, and generated wrappers to identify binary responses, schema mismatches, endpoint errors, and parameter type issues.
  • Targeted remediation: Update tool run() implementations, adjust return_schema and parameter schemas, make mutually-exclusive params nullable, fix endpoints, and add binary-response metadata handling.
  • Verification & regeneration: Regenerate tool wrappers, run integration tests and unit tests, and produce a concise fix summary for handoff or commit.
  • Use case: Fix a failing ChEMBL image endpoint that raises JSON parse errors by detecting image content-types, returning metadata instead of parsing, and updating the tool's return_schema and tests.

Quick Start

Run a verbose diagnostic on the failing ToolUniverse tool, identify schema or binary-response issues, propose code and JSON config changes, and verify by re-running tests.

Frequently Asked Questions about devtu-fix-tool

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix a ToolUniverse tool that fails schema validation?▼

Fix schema validation failures by running verbose diagnostics to inspect API responses, updating the tool's return_schema, correcting parameter typing, and regenerating generated wrappers for final verification.

Why does my REST API tool return JSON parse errors for binary responses?▼

JSON parse errors occur when REST API tools receive binary content-types. Resolve this by detecting image content-types, returning metadata instead of parsing, and updating the return_schema accordingly.

How do I debug failing integration tests for Python API tools?▼

Debug failing integration tests by executing targeted verbose tests, inspecting API headers and responses for endpoint errors, adjusting mutually-exclusive parameters, and rerunning unit and integration tests.

What is the best way to handle nullable and mutually-exclusive parameters in API testing?▼

Handle nullable and mutually-exclusive parameters during API testing by updating tool run() implementations, adjusting parameter schemas to allow nulls, and verifying valid test_examples end-to-end.

Can I use this workflow to correct endpoint errors in local ToolUniverse configurations?▼

Yes, you can use this workflow to correct endpoint errors in local ToolUniverse configurations by applying targeted remediation to REST-api backed tools and verifying fixes through wrapper regeneration.

What should I do when regenerating generated wrappers does not fix test failures?▼

When regenerating wrappers does not fix test failures, inspect content-type checks, verify return_schema alignment, ensure valid test_examples, and confirm correct endpoint corrections before re-running tests.
