🔁 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.

🌐 i18n Completeness Auditor

by JustHandled Labs

$12

Audit a JavaScript or TypeScript frontend for missing translations and hardcoded UI strings before you ship a new locale. Flags hardcoded JSX text and UI props (title, placeholder, aria-label, label, alt) not wrapped in t(), i18n.t(), or <Trans>; keys present in the default locale but missing from other locale files; keys referenced in code but absent from the locales (the raw dotted keys that leak to users); unused locale keys; and unparseable locale JSON.

📚 Reference Grounding Checker

by JustHandled Labs

$15

Before an agent acts on a plan, verify that the things it named actually exist. Checks each referenced file path, function or method, import or package, environment variable, and CLI command against your repo, and flags the ones that do not resolve. Catches the hallucinated function and the phantom package before the edit, not after the build breaks. Resolves Python and JavaScript/TypeScript.

🔳 QR Payload Auditor

by JustHandled Labs

$5

Audit the decoded text a QR code carries before you print it on something. Flags URLs that are not absolute, link shorteners that hide the real destination, unsafe schemes (javascript:, data:, file:), payloads too long to scan reliably, malformed Wi-Fi or contact payloads, and exposed credentials like a Wi-Fi password or a token sitting in a URL. It audits the decoded payload you paste; it does not read images.
