Summarizer
Summarizes large text content into concise summaries
marketplace-publishing
Workflow for publishing skills and agents to the dotnet-skills Claude Code marketplace. Covers adding new content, updating plugin.json, validation, and release tagging.
authoring-dags
Workflow and best practices for writing Apache Airflow DAGs. Use when the user wants to create a new DAG, write pipeline code, or asks about DAG patterns and conventions. For testing and debugging DAGs, see the testing-dags skill.
code-foundations
Use when doing ANY code task - writing, debugging, reviewing, fixing, implementing, optimizing, or refactoring. Symptoms that trigger this skill include seeing code, being asked to implement something, fix a bug, review code, or improve performance. This skill dispatches to specific skills based on task type. Includes both Code Complete (cc-*) and APOSD (aposd-*) skill families.
cc-table-driven-methods
Use when writing if/else chains with 3+ branches, creating inheritance hierarchies per variant, or encountering volatile data formats that change without code changes. Triggers on: too many if statements, switch statement growing, subclass per type, customer-controlled format, data-driven behavior, lookup table, mapping data to actions.
building
Execute whiteboard plans with checklist-based tracking. Use after /code-foundations:whiteboarding to implement saved plans. Triggers on: build it, execute plan, implement the whiteboard, run the plan. Loads plan from docs/plans/, tracks progress, produces working code with tests.
cc-documentation-quality
Review documentation quality including README, comments, API docs, changelog, and AI documentation (CLAUDE.md, .cursorrules, copilot-instructions, etc.). Use when checking if documentation matches code, comments are fresh, or new features lack documentation. Based on Code Complete Ch. 32 and APOSD comments philosophy.
pptx
Presentation creation, editing, and analysis. When Claude needs to work with presentations (.pptx files) for: (1) Creating new presentations, (2) Modifying or editing content, (3) Working with layouts, (4) Adding comments or speaker notes, or any other presentation tasks
claude-hook-writer
Expert guidance for writing secure, reliable, and performant Claude Code hooks - validates design decisions, enforces best practices, and prevents common pitfalls
lean4-theorem-proving
Use when working with Lean 4 (.lean files), writing mathematical proofs, seeing "failed to synthesize instance" errors, managing sorry/axiom elimination, or searching mathlib for lemmas - provides build-first workflow, haveI/letI patterns, compiler-guided repair, and LSP integration
testing-unit-tests
This skill provides minimal guidance for handling unit tests by referencing an external standards document. It lacks concrete instructions, examples, or specific testing frameworks. The skill essentially functions as a placeholder that tells users to check another file for actual content.
cloudflare-d1
Complete knowledge domain for Cloudflare D1 - serverless SQLite database on Cloudflare's edge network. Use when: creating D1 databases, writing SQL migrations, configuring D1 bindings, querying D1 from Workers, handling SQLite data, building relational data models, or encountering "D1_ERROR", "statement too long", "too many requests queued", migration failures, or query performance issues. Keywords: d1, d1 database, cloudflare d1, wrangler d1, d1 migrations, d1 bindings, sqlite workers, serverless database, edge database, d1 queries, sql cloudflare, prepared statements, batch queries, d1 api, wrangler migrations, D1_ERROR, D1_EXEC_ERROR, statement too long, database bindings, sqlite cloudflare, sql workers api, d1 indexes, query optimization, d1 schema
workspace-unified
Unified Google Workspace management via WorkspaceACSet. Transforms operations into GF(3)-typed Interactions across Gmail, Drive, Calendar, Tasks, Docs with cross-skill morphisms and MCP↔API equivalence. Use for multi-service workflows or applying ACSet principles to workspace automation.
unison
Unison language - content-addressed functional programming with abilities for effects, distributed computing, and structural types. Use for pure functional code, effect management, distributed systems, and refactoring-safe codebases.
prose-polish
Evaluate and elevate writing effectiveness through multi-dimensional quality assessment. Analyzes craft, coherence, authority, purpose, and voice with genre-calibrated thresholds. Use for refining drafts, diagnosing quality issues, generating quality content, or teaching writing principles.
doc-ears-validator
Imported from https://github.com/vladm3105/aidoc-flow-framework.
web-browse
Browse and interact with web pages headlessly. Use when agent needs to navigate websites, click elements, fill forms, read content, or take screenshots.
enhance-docs
Use when improving documentation structure, accuracy, and RAG readiness.
frontend-css
This skill provides minimal CSS coding guidance by referencing an external standards document. It lacks concrete examples, specific rules, or actionable instructions for Claude to follow when writing CSS. The skill essentially functions as a placeholder that points to another file without providing actual implementation details.
docx
Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. When Claude needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks
scribe-role-skill
Professional technical writing and documentation skill for creating and maintaining comprehensive, accurate, and user-friendly documentation for codebases, APIs, deployment processes, and end-user guides.
prompt-brevity
Review AI prompts and instructions for conciseness and clarity. Use when reviewing skills, CLAUDE.md, slash commands, or any LLM prompt content.
google-sheets

Use for spreadsheet data operations, cell ranges, formulas, formatting, batch updates, and data analysis workflows. Shares OAuth token with email, calendar, contacts, drive, and docs skills.
convex-return-validators
Guide for when to use and when not to use return validators in Convex functions. Use this skill whenever the user is writing Convex queries, mutations, or actions and needs guidance on return value validation. Also trigger when the user asks about Convex type safety, runtime validation, AI-generated Convex code, Convex AI rules, Convex security best practices, or when they're debugging return type issues in Convex functions. Trigger this skill when users mention "validators", "returns", "return type", or "exact types" in the context of Convex development. Also trigger when writing or reviewing Convex AI rules or prompts that instruct LLMs how to write Convex code.
