Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Final production and publishing for a book project: gate on every chapter being final, assemble the manuscript and front/back matter in STATUS order, format to DOCX via officecli-docx, generate metadata, blurb, a non-fiction index and bibliography, and a KDP/IngramSpark platform prep checklist. Use when a copy-clean manuscript is ready to be turned into an uploadable package.
Creates Keep-a-Changelog compliant CHANGELOG.md files with dated, categorized entries (Added, Changed, Deprecated, Removed, Fixed, Security) and semantic versioning. Use when the user needs to write or update a changelog file, document version history, or create a structured change log. Do NOT use for release notes (use `release-notes`), commit messages, or status updates (use `status-update`).
Formats citations and reference lists in APA, MLA, Chicago, or IEEE style with precise adherence to each style's rules. Converts between styles and checks citation accuracy. Use when the user asks to format citations, create a reference list, convert citation styles, or check citation formatting against a specific style guide. Do NOT use for literature review writing (use literature-review), paper structure (use research-paper-structure), or general editing (use copy-editing).
Produces a conditional formatting rule set for a specific use case. Specifies rule type (cell value, formula-based, color scale, data bars), criteria, color assignments with hex codes, and rule priority order. Output is the exact configuration to apply. Use when the user wants to highlight cells, create heat maps, add data bars, or visually encode data values in a spreadsheet. Do NOT use for chart color selection (use color-in-data), data validation rules (use data-validation-setup), or general spreadsheet formulas (use excel-lookup-formulas).
Creates structured notes using the Cornell method with a cue column, notes section, and summary for learners. Produces a filled-in Cornell notes template from provided content -- not an explanation of how Cornell notes work. Use when a learner asks to take notes using the Cornell method, organize lecture notes, create structured study notes, or convert raw notes into Cornell format. Do NOT use for concept mapping (use `concept-mapping`), for note synthesis across sources (use `note-synthesis`), or for flashcard creation (use `flashcard-generation`).
Quick techniques for cleaning CSV files - deduplication, normalization, encoding fixes, merging, and common data quality repairs using command-line tools and scripting. Use when the user asks about csv data cleaner, related techniques, best practices, or needs guidance in this domain. Do NOT use when the request is outside the scope of csv data cleaner or requires a different specialized skill.
Expert data format transformation covering CSV parsing edge cases, encoding detection, JSON/XML/Parquet/Avro conversion, data type inference, schema validation, large file handling with streaming parsers, delimiter detection, and handling of malformed data across all common data interchange formats. Use when the user asks about csv transformer, csv transformer best practices, or needs guidance on csv transformer implementation. Do NOT use when the user needs a different specialized skill or is asking about an unrelated technology domain.
Generates a priority-ordered data cleaning protocol for a specific dataset. Identifies quality issues (duplicates, nulls, type mismatches, outliers) and produces the exact cleaning operations with formulas and documentation. Use when the user has a dataset with quality problems and needs a systematic plan to clean it before analysis. Do NOT use for initial data exploration (use eda-framework), statistical testing (use hypothesis-testing), or writing SQL/Python cleaning scripts (software-development scope).
Produces chart specifications for presentation slides including chart type selection for each data comparison, simplified data optimized for presentations, and insight headlines above each chart. Uses Decision 8 chart selection logic with presentation-specific simplification. Use when the user asks to add data or charts to a presentation, visualize data in slides, or show numbers in a slide deck. Do NOT use for standalone data visualization outside presentations (use chart-type-selector), full dashboard design (use dashboard-design), or slide deck overall structure (use slide-deck-structure).
Step-by-step guidance for backing up photos to the cloud, organizing pictures into albums, sharing photos with family, and using printing services to turn digital memories into physical keepsakes. Use when the user asks about digital photo organizer, related techniques, best practices, or needs guidance in this domain. Do NOT use when the request is outside the scope of digital photo organizer or requires a different specialized skill.
