ADK Agent Development And Engineering

jeremylongshore/claude-code-plugins-plus-skills

A specialized skill for architecting, building, and productionizing complex Agent Development Kit (ADK) agents and multi-agent systems. This process emphasizes best practices, including clean module structure, robust tool integration, comprehensive regression testing, and deployment automation for reliable, shippable AI solutions. Use this when requiring the creation of structured, enterprise-grade agent code.

Agent C++ Testing

affaan-m/everything-claude-code

Guides an agent through C++17/20 testing with CMake, CTest, and GoogleTest/Mock, covering new or flaky tests, CI gates, coverage builds, and sanitizer diagnostics to keep regression safety in place.

Performance Regression Detector

detecting-performance-regressions

jeremylongshore/claude-code-plugins-plus-skills

Automatically analyzes CI/CD performance metrics, compares them against baselines and thresholds, and flags statistical regressions so teams catch response-time or throughput degradations before deployment.

Differential Security Review

differential-review

trailofbits/skills

Performs security-focused differential review of PRs, commits, and diffs, adapting depth to repo size, tracing git history, estimating blast radius, checking coverage, and producing detailed markdown reports to stop regressions.

End-to-End Testing Patterns Guide

e2e-testing-patterns

sickn33/antigravity-awesome-skills

This skill provides comprehensive guidance on building reliable, fast, and maintainable end-to-end (E2E) test suites. It ensures code quality by validating critical user journeys and catching regressions in complex workflows before deployment. Essential for setting up robust CI/CD pipelines, cross-browser compatibility, and establishing rigorous QA standards.

Verify Fix Commits Against Audit Findings

sickn33/antigravity-awesome-skills

This skill provides a structured methodology for reviewing code commits intended to fix security vulnerabilities or address audit findings. It ensures that the original root cause is properly resolved, verifies the fix hasn't introduced new bugs or vulnerabilities (regressions), and validates the overall completeness of the remediation effort. Ideal for security-critical code reviews.

Git Advanced Workflows

rohitg00/awesome-claude-code-toolkit

Documents advanced Git workflows—worktrees, bisect, interactive rebase, hooks, recovery tactics, aliases, and anti-patterns—so developers can manage parallel branches, pinpoint regressions, and enforce commit hygiene in complex repos.

Snapshot Test Manager

managing-snapshot-tests

jeremylongshore/claude-code-plugins-plus-skills

Manages snapshot tests for Jest, Vitest, Playwright, and Storybook by analyzing failures, distinguishing intentional changes from regressions, and selectively updating only the affected snapshots to keep suites accurate.

Lighthouse Performance Audits

perf-lighthouse

tech-leads-club/agent-skills

Run local Lighthouse audits via CLI or Node API, parse JSON/HTML reports, enforce performance budgets, integrate with CI (Actions/LHCI), and compare builds to catch regressions before deploys.

Visual Regression Testing

performing-visual-regression-testing

jeremylongshore/claude-code-plugins-plus-skills

Runs automated visual regression tests via Percy, Chromatic, or BackstopJS to capture component or page screenshots, compare them against baselines, and flag unintended UI changes during feature updates or CI/CD runs.

Advanced Perplexity API Debugging Tools

perplexity-advanced-troubleshooting

jeremylongshore/claude-code-plugins-plus-skills

This skill provides comprehensive, multi-layered diagnostic scripts for resolving complex and intermittent issues with the Perplexity Sonar API. It allows users to test connectivity (DNS, TLS, TCP), profile API latency, validate citation stability, and verify search recency filters. It is crucial when standard troubleshooting methods prove insufficient for diagnosing hard-to-replicate API bugs or performance regressions.

Sentry CI/CD Deployment And Release Tracking

sentry-deploy-integration

jeremylongshore/claude-code-plugins-plus-skills

Integrate Sentry into your CI/CD pipeline to achieve end-to-end release tracking. This skill guides you through using the Sentry CLI and SDK to record deployments, associate commits, upload source maps, and monitor crucial release health metrics. Key functions include detecting regressions, calculating crash-free session rates, and tracking user adoption curves for every deployed version.
