AI Agent Skills Marketplace

Architects the right retrieval strategy for every query — teaching your agent when to use RAG, a knowledge graph, or a temporal index instead of defaulting to vector search for everything.

Catches dangerous database migrations before they hit production. Reviews schema changes for locking hazards, data loss, missing rollbacks, and index issues across PostgreSQL, MySQL, and SQLite.

Diagnoses why your project will not start. Checks runtime versions, dependencies, environment variables, databases, ports, and build artifacts systematically.

Design, debug, and optimize production RAG systems with expert architecture, hybrid search, and grounding strategies.

Turn plain English app descriptions into fully normalized SQL schemas and entity relationship documentation.

Production-safe database migrations with zero-downtime strategies, batch backfilling, and multi-ORM support.

A safety-first framework for professional database modeling, zero-downtime migrations, and risk-aware schema evolution.

Supabase RLS Doctor

by JustHandled Labs

$19

or 95 cr

Audit your Supabase project for the row-level-security mistakes that quietly expose data: tables without RLS, policies that resolve to true, leaked service-role keys, missing auth.uid() checks, open storage buckets, overbroad grants, and migration drift. A local, read-only scan plus a full review checklist, each finding with severity, evidence, and a fix. No database changes without confirmation.

AI Code Verification Gate

by JustHandled Labs

$19

or 95 cr

One-line summary description Stop your agent from claiming "done" before it's proven. A verification gate that classifies each change by risk (payment, auth, database, user-facing), picks the tests that actually cover it, demands evidence, maps regression risk, and outputs an honest pass/fail report. Turns "looks good to me" into "here's what I ran, and here's what's still unverified."

Docker Compose Stack Doctor

by JustHandled Labs

$15

or 75 cr

Diagnose why your Docker Compose stack won't come up: port conflicts, bad or missing env vars, absent healthchecks, volume and permission issues, depends_on that doesn't wait for readiness, networking gaps, platform mismatches, and databases that aren't ready. Reads your docker-compose.yml and logs and ranks the blockers with fixes.

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.

Schema mistakes are the most expensive kind — code refactors in days, but a wrong table design holds your data hostage for years

API Rate Limiter Designer

by Arnstein Larsen

$8.99

or 45 cr

Rate limiting fails in two directions: too loose and one bad client takes down the database for everyone; too crude and you rate-limit your own legitimate power users into churn

⚠️ Dangerous Command Linter

by JustHandled Labs

$12

or 60 cr

Flag the destructive operations in a shell command or script before anyone runs it. Catches recursive force deletes, force pushes and history rewrites, database drops and truncates, disk-wipe commands (mkfs, dd to a device), permission blowouts (chmod 777), remote content piped into a shell, broad wildcard deletes, and prod-targeting or disabled-safety flags. Each finding comes with a severity and a safer alternative.
