🔁 Model Migration Checker

by JustHandled Labs

$6/mo

Find the model-version coupling that breaks when you swap LLMs. Flags hardcoded model names and versions, deprecated or renamed parameters (the max_tokens to max_completion_tokens class of change), hardcoded token and context-window limits, response-format parsing tied to one model's output, tool-schema format coupling between providers, and hardcoded per-token cost constants. The patterns load from an editable model-rules table you update as new models ship.

Audit dependencies for security, licenses, and health while generating a phased, low-risk upgrade and migration plan.

A complete Manifest V3 Chrome extension to detect and highlight manipulative UI dark patterns on any website.

🗺️ Change Impact Mapper

by JustHandled Labs

$13

Map the blast radius of a code change before you run the whole suite. For the files and functions you changed, it lists what imports or calls them, which tests cover them, flags any change with no covering test, and warns when a file has a lot of dependents. It tells an agent what its edit might break instead of making it guess. Resolves Python and JavaScript/TypeScript.

🧪 Test Quality Auditor

by JustHandled Labs

$15

Find the unit tests that pass without testing anything. Flags tests with no assertions, trivial existence-only checks (toBeDefined, assertIsNotNone), tests that assert the exact value they just mocked, snapshot-only tests, tautological assertions (expect(true).toBe(true)), empty placeholders, and over-mocked tests with more setup than assertions. Works on Jest/Vitest and pytest/unittest.

⚡ Perf Budget Auditor

by JustHandled Labs

$12

Reads a webpack or Vite-style stats.json plus a perf-budget.json you control.
