25 in the ChatGPT listing

• API And Interface DesignUse when designing APIs, module boundaries, or any public interface.
• Browser Testing With DevtoolsUse when a browser-based application needs real runtime inspection, DOM verification, console or network debugging, performance profiling, screenshots, or end-to-end browser testing.
• CI CD And AutomationUse when setting up or modifying build and deployment pipelines.
• Code Review And QualityUse when reviewing code written by yourself, another agent, or a human.
• Code SimplificationUse when refactoring code for clarity without changing behavior.
• Constraint Driven DevelopmentUse when a project needs an explicit quality bar, enforceable standards, coverage or performance thresholds, or safeguards against agents weakening checks to get green.
• Context EngineeringUse when starting a new session, when agent output quality degrades, when switching between tasks, or when you need to configure rules files and context for a project.
• Debugging And Error RecoveryUse when tests fail, builds break, something that worked yesterday broke, behavior doesn't match expectations, or you encounter any unexpected error.
• Deprecation And MigrationUse when removing old systems, APIs, or features.
• Documentation And AdrsUse when you need to document an architecture decision (ADR) or the reasoning behind a design choice, when changing public APIs, shipping features, or when you need to record context that future engineers and agents will need to understand the codebase.
• Doubt Driven DevelopmentUse when a plan or implementation needs adversarial scrutiny because assumptions are uncertain, stakes are high, or correctness matters more than speed.
• Frontend UI EngineeringUse when building or modifying interfaces and pages, creating components, implementing layouts, meeting WCAG accessibility requirements, managing state, or when the output needs to look and feel production-quality rather than AI-generated.
• Git Workflow And VersioningUse when making any code change.
• Idea RefineUse when an idea is vague, alternatives need expanding, assumptions need stress-testing, or the user wants to refine an idea before committing to a plan.
• Incremental ImplementationUse when implementing any feature or change that touches more than one file, or when picking up the next task from a plan.
• Interview MeUse when a request is underspecified, important requirements are ambiguous, or the user asks to be interviewed or grilled before planning or implementation.
• Observability And InstrumentationUse when adding logging, metrics, tracing, or alerting.
• Performance OptimizationUse when an application has performance requirements, regressions, slow pages or queries, poor Core Web Vitals, N+1 patterns, or measured bottlenecks that need optimization.
• Planning And Task BreakdownUse when you have a spec or clear requirements and need to break work into implementable tasks.
• Security And HardeningUse when code handles untrusted input, authentication, sessions, sensitive data, external integrations, dependency vulnerabilities, or needs a security review against common attack classes.
• Shipping And LaunchUse when preparing to deploy to production, or when asking what needs to be in place before shipping.
• Source Driven DevelopmentUse when you want to verify an approach against the official docs before implementing it, or when you want authoritative, source-cited code free from outdated patterns.
• Spec Driven DevelopmentUse when starting a new project, feature, or significant change and no specification exists yet.
• Test Driven DevelopmentUse when implementing any logic, fixing any bug, or changing any behavior.
• Using Agent SkillsUse when starting a session, or when you need to decide which skill or workflow applies to the piece of work at hand.
