## About

Tools are callable endpoints; skills are reusable instruction packages that guide how those tools are used. This snapshot contains 232 tool interfaces and 44 complete main skill files.

Skill pages reproduce their complete current SKILL.md source. The tool reference preserves the exposed descriptions and TypeScript declarations. Availability can change with session configuration, permissions, connected apps, and installed plugins.

Every available skill has its own page containing a verbatim copy of its main definition.

Presentations Read, create or edit PowerPoint or Google Slides decks. Use for presentation, slide deck, PowerPoint, PPT, PPTX, or Google Slides requests. →

Spreadsheets Use this skill when a user requests to create, modify, analyze, visualize, or work with spreadsheet files (`.xlsx`, `.xls`, `.csv`, `.tsv`) or Google Sheets-targeted spreadsheet artifacts with formulas, formatting, charts, tables, and recalculation. →

223 registry tools and 9 direct session controls, grouped by purpose.

The `apply_patch` tool can be used to edit files. This is a FREEFORM tool, so do not wrap the patch in JSON.
