🎨 Brand Consistency Linter

by JustHandled Labs

$12

or 60 cr

Hold your bios, footers, and profiles to one brand spec. Flags brand-name spelling and casing that does not match your canonical form, off-spec taglines, links that are not on your official list, leftover placeholders (Lorem, TODO, "your tagline here"), and handles that differ from one surface to the next. You define the spec once and it enforces it everywhere.

🌐 i18n Completeness Auditor

by JustHandled Labs

$12

or 60 cr

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.

Token Budget Officer — Cap AI Token Spend & Downshift Expensive Runs Automatically

by PubsProToolkit

$5

or 25 cr

An adversarial gate to verify AI-use disclosures and draft compliant provenance statements for any venue.

🔁 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.

🗄️ SQL Migration Safety Doctor

by JustHandled Labs

$12

or 60 cr

Catch the dangerous migration before it locks or wrecks your production database. Scans SQL migration files for destructive and risky operations: DROP and TRUNCATE, drops without IF EXISTS, lossy column-type changes, NOT NULL added without a default, DELETE or UPDATE with no WHERE, non-concurrent index builds, dropped constraints, renames, and data backfills mixed into schema changes. Each finding is ranked by severity with a safer rewrite. Postgres, MySQL, and SQLite.

Codebase Explainer & Onboarding Mapper — Understand Any Unfamiliar Repo Fast (Architecture, Key Modules, How to Run It)

$14

or 70 cr

Point it at an unfamiliar or inherited repo and quickly understand it. Maps the architecture, identifies the key modules and entry points, traces the core end-to-end flows, surfaces the conventions and gotchas, and assembles a clean ONBOARDING.md — turning a strange codebase into a clear mental model fast. Built for the moment you join a project, take one over, or have to explain a repo before changing it.
