Skills Catalog¶
Source: hooks/ways/skills-catalog.md
Curated index of official and vetted skills. Ways reference these — they don't duplicate them.
Install official skills: /plugin marketplace add anthropics/skills then /plugin install <plugin-name>@anthropic-agent-skills

Gap Analysis: What Ways Would Add¶
Skills are procedures — they tell Claude how to do something. Ways are judgment — they tell Claude when and why.
| Domain | Skills exist | Way would add |
|---|---|---|
| Writing | doc-coauthoring, internal-comms, docx | When to use which format, audience analysis, tone calibration, when to co-author vs just write |
| Research | (none) | Structured investigation, source evaluation, synthesis, comparative analysis |
| Presentation | pptx, theme-factory | Narrative arc, slide structure decisions, when slides vs docs vs diagrams |
| Data/Analysis | xlsx | When to use spreadsheets vs charts vs tables, data storytelling |
| Creative | algorithmic-art, canvas-design, slack-gif-creator | (sparse — creative work is hard to systematize into ways) |
Proposed Way Domains¶
writing/ — Fire on content creation prompts. Reference official skills for execution.
- writing/draft → points to doc-coauthoring skill for structured docs
- writing/presentation → points to pptx + theme-factory skills
- writing/report → points to docx/pdf skills, adds structure guidance
- writing/edit → revision and tone guidance (no skill equivalent)
research/ — No official skills exist here. This is greenfield.
- research/explore → structured investigation methodology
- research/compare → comparative analysis, decision matrices
- research/summarize → distillation patterns
- research/sources → citation and verification protocol
