requesting-code-review

Use when completing tasks, implementing major features, or before merging to verify work meets requirements - dispatches superpowers:code-reviewer subagent to review implementation against plan or requirements before proceeding

UncategorizedView skill →

root-cause-tracing

Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior

UncategorizedView skill →

secure-coding-practices

Secure coding practices and defensive programming patterns for building security-first applications. Use when implementing authentication, handling user input, managing sensitive data, or conducting secure code reviews.

UncategorizedView skill →

security-testing-patterns

Security testing patterns including SAST, DAST, penetration testing, and vulnerability assessment techniques. Use when implementing security testing pipelines, conducting security audits, or validating application security controls.

UncategorizedView skill →

session-management

Use when loading, saving, or reflecting on session context - provides structured workflows for session lifecycle management and reflection outputs.

UncategorizedView skill →

sharing-skills

Use when you've developed a broadly useful skill and want to contribute it upstream via pull request - guides process of branching, committing, pushing, and creating PR to contribute skills back to upstream repository

UncategorizedView skill →

skill-creator

Guide for creating effective skills. Use when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

UncategorizedView skill →

subagent-driven-development

Use when executing implementation plans with independent tasks in the current session - dispatches fresh subagent for each task with code review between tasks, enabling fast iteration with quality gates

UncategorizedView skill →

system-design

Use when designing system architecture, APIs, components, or data models - provides a structured design workflow with validation and documentation outputs.

UncategorizedView skill →

systematic-debugging

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions

UncategorizedView skill →

task-orchestration

Use when coordinating complex tasks with orchestration, delegation, or parallel workstreams - provides structured workflows for orchestrate:brainstorm, orchestrate:spawn, and orchestrate:task.

template-skill

A template for creating new skills. Use when initializing a new skill to ensure proper structure and metadata.

UncategorizedView skill →

terraform-best-practices

Terraform infrastructure-as-code best practices for scalable and maintainable cloud infrastructure. Use when writing Terraform modules, managing infrastructure state, or implementing infrastructure automation at scale.

UncategorizedView skill →

test-driven-development

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

UncategorizedView skill →

test-generation

Use when generating tests for new or existing code to improve coverage - provides a structured workflow for analyzing code, creating tests, and validating coverage goals.

UncategorizedView skill →

testing-anti-patterns

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

UncategorizedView skill →

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
