design-export-repair

Fixes broken decks/PDFs exported from Claude's "Design" feature (or similar AI deck generators) — cut-off or clipped text, wrong/substituted fonts, and corrupted .pptx package structure that shows up only once you export to PDF, not while looking at it in the app. Use this skill whenever the user uploads a zip, .pptx, or .pdf exported from Claude Design (or mentions "Design" export, an AI-generated deck, or a generated slide deck/PDF) AND reports it looking broken, wrong, cut off, garbled, or different from the original when opened, printed, or converted to PDF — even if they don't use the word "repair" or name the specific defect. Also trigger for general "my exported PDF/deck is broken, help fix it" requests when the file was clearly produced by an AI design/deck tool rather than hand-authored. Produces both a repaired, still-editable .pptx and a clean PDF, plus a report of exactly what was wrong and what changed.

cash-flow-forecaster

Build a 13-week rolling cash flow forecast from bank exports, AR aging, AP bills, payroll, and recurring commitments -- the report that tells a small business whether it survives the quarter. Flags the crunch weeks early enough to act.

commercial-lease-analyzer

Decode a commercial lease before signing or renewing -- true all-in occupancy cost (base rent plus NNN/CAM plus escalations), the clauses that hurt small tenants (personal guarantees, relocation, restoration), and the negotiation asks landlords routinely grant. The lease is most SMBs' biggest fixed cost and least-read document.

Database Schema Designer

Design optimized, scalable database schemas with proper relationships and indexes.

Contents

references/schema-templates.md — SQL/NoSQL schema templates, ASCII ERD, and migration script templates.

references/output-format.md — labeled section structure for the final deliverable.

references/best-practices.md — naming, data types, indexes, relationships, SQL/NoSQL design rules, and the output quality checklist.

Workflow

Gather requirements. Determine the database engine (PostgreSQL, MySQL, MongoDB, etc.), application domain, main entities, most common queries, expected data volume and growth, performance requirements, and any compliance constraints.

Design the schema. Apply the engine-appropriate rules in references/best-practices.md (SQL Database Design or NoSQL Database Design).

Generate the complete schema. Produce CREATE TABLE statements or collection documents using the templates in references/schema-templates.md.

Create the entity relationship diagram in text format following the ERD template in references/schema-templates.md.

Provide migration scripts with both up and down (rollback) paths, per the migration template in references/schema-templates.md.

Format the complete output using the labeled sections in references/output-format.md.

Verify the result against the output quality checklist in references/best-practices.md.
