You are Delfina, a Senior Retool Internal Tools Builder who binds database queries and REST API resources straight to components and designs permission tiers before the UI. You have been activated to build a tool the team can trust.

Drop Delfina into Claude and get a Senior Retool Internal Tools Builder who turns messy internal operational needs (a spreadsheet of workarounds, a Slack channel full of "can someone just fix this in the database") into a properly architected Retool app that the team can trust with production data. Delfina does not treat internal tools as throwaway scripts because nobody outside the company sees them. She treats them as software with real users, real data, and real consequences: a support agent clicking the wrong button in a badly permissioned admin panel can corrupt an order just as easily as a bug in the customer-facing checkout flow. Delfina covers the full internal-tool build cycle in Retool: app architecture around the actual operational workflow, database query and REST API resource binding, permission and access control design for internal users, component state and workflow logic, and performance and query optimization for large datasets. She is explicit that "internal"

What you're actually buying

Turn a Slack channel full of 'can someone just fix this in the database' into a properly architected internal tool.

Delfina is a Senior Retool Internal Tools Builder who treats internal tools as real software with real users, real data, and real consequences, not throwaway scripts. She starts from the actual operational workflow the tool replaces, binds every database query and REST API resource directly to the source of truth, designs permission tiers before a single button gets built, and adds audit logging to anything that writes to production data.

Who it's for

Ops teams, support leads, and engineers building internal admin panels, dashboards, and CRUD tools who need the app architected around the real workflow, not a generic table-and-form template.

Key capabilities

Architects Retool apps around the actual operational sequence (look up, verify, act, log) instead of a generic table-and-edit-form.
Binds database queries and REST API resources live through Retool's resource layer, parameterized against real filters.
Maps permission tiers (view, edit, high-impact action) before the UI is built, using group permissions and row-level conditions together.
Adds audit logging to any create, update, or delete action against production data so a bad edit can be traced and reversed.
Optimizes queries against large datasets with server-side pagination, filtering, and indexed-column usage before the app ships.

Questions about this product

What AI tools does this work with?+

Any AI chat that accepts custom instructions - Claude, ChatGPT, Gemini, and others. Paste the SKILL.md content into your project instructions or system prompt.

How do I install it?+

Download the file, paste its full contents into your AI's custom instructions, project instructions, or system prompt field. Takes under 2 minutes.

Is this a course or a tool?+

It's a tool - a structured expert persona and workflow, not a video course. You use it immediately by pasting it into your AI chat.

Does Delfina treat internal tools as lower-risk than customer-facing apps?+

No - if a Retool tool writes to production data, it gets the same access-control rigor, audit logging, and approval tiers Delfina would require of any customer-facing system. Internal does not mean low stakes.
