testing-skills-with-subagents
Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes
writing-for-a-technical-audience
Use when writing documentation, guides, API references, or technical content for developers - enforces clarity, conciseness, and authenticity while avoiding AI writing patterns that signal inauthenticity
creating-an-agent
Use when creating specialized subagents for Claude Code plugins or the Task tool - covers description writing for auto-delegation, tool selection, prompt structure, and testing agents
writing-good-tests
Use when writing or reviewing tests - covers test philosophy, condition-based waiting, mocking strategy, and test isolation
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
technical-writing
Writes technical blog posts about features being built. Triggers when user asks to write about development progress, implementations, or project updates.
databases
Work with MongoDB (document database, BSON documents, aggregation pipelines, Atlas cloud) and PostgreSQL (relational database, SQL queries, psql CLI, pgAdmin). Use when designing database schemas, writing queries and aggregations, optimizing indexes for performance, performing database migrations, configuring replication and sharding, implementing backup and restore strategies, managing database users and permissions, analyzing query performance, or administering production databases.

docs-manager-skill
Orchestrates complete single-document workflows with automatic validation and indexing in a write→validate→index pipeline
data-quality-checker
Validate data quality in market analysis documents and blog articles before publication. Use when checking for price scale inconsistencies (ETF vs futures), instrument notation errors, date/day-of-week mismatches, allocation total errors, and unit mismatches. Supports English and Japanese content. Advisory mode -- flags issues as warnings for human review, not as blockers.
learned-docs
This skill should be used when writing, modifying, or reorganizing documentation in docs/learned/. Use when creating new documents, updating frontmatter, choosing categories, creating index files, updating routing tables, or moving files between categories. Essential for maintaining consistent documentation structure.
backend-queries
Write secure, performant database queries using parameterized statements, proper indexing, and query optimization techniques. Use this skill when writing SQL queries, ORM query methods, or database access code. When implementing data fetching logic that retrieves or updates database records. When optimizing queries to prevent N+1 problems through eager loading or joins. When using WHERE clauses, JOIN operations, or ORDER BY statements. When implementing transactions for related database operations. When working with query builder methods, raw SQL, or ORM query interfaces. When setting query timeouts or implementing query result caching.
testing-test-writing
Write focused tests for core user flows and critical business logic, testing behavior rather than implementation, with clear names and fast execution. Use this skill when writing unit tests, integration tests, or end-to-end tests. When testing critical user workflows and primary application features. When creating tests that focus on what code does rather than how it does it. When mocking external dependencies like databases, APIs, or file systems. When naming tests to clearly describe the scenario and expected outcome. When keeping tests fast and independent. When completing feature implementation and adding strategic tests at logical completion points. When working with test files or test frameworks.
