Solution exploration and implementation. Generate 2-3 approaches, pick simplest. Never implement first idea. Triggers: build, implement, create, feature, add.

Systematic debugging methodology based on Zeller's scientific method. Reproduce, hypothesize, predict, test, isolate via binary search, fix root cause. Every fix gets a regression test. Triggers: bug, error, fix, broken, not working, fails, crashed, unexpected, stack trace, regression, exception.

Testing methodology and strategy. Tests prove behavior, not implementation. Triggers: test, tests, coverage, assertion, mock, fixture, spec, verify.

Git workflow and version control best practices. Atomic commits, conventional messages, branch strategies, merge protocols. Triggers: commit, branch, merge, rebase, git, push, pull, PR, version control.

Security best practices and vulnerability prevention. Input validation, authentication, secrets management, OWASP top 10. Triggers: security, auth, authentication, secrets, credentials, vulnerability, injection, XSS, CSRF, rate-limit.

REST API design patterns. Resource naming, status codes, pagination, error responses, versioning. Triggers: api, rest, endpoint, route, http, status-code, pagination.

Safe refactoring methodology. Behavior-preserving transformations only. Tests green before AND after. Triggers: refactor, clean, simplify, restructure, extract, inline.

Mobile/web app build pipeline: fastlane-first local builds, store submission, pre-submission checklists. Triggers: app, mobile, store submission, build, deploy app, fastlane, expo, react native, flutter.

Release-gate sequence: validate → review → push → tag. Wraps kernel:git mechanics with the pre-ship safety chain. Triggers: ship, release, push to main, ready to merge, deploy.

System architecture and design patterns. Modular design, interface stability, dependency management, AI-code health nexus. Triggers: architecture, design, structure, modules, dependencies, coupling, system design.

Backend architecture patterns. Repository pattern, caching, queues, N+1 prevention, transactions. Triggers: backend, server, database, cache, redis, queue, repository, service.

Context engineering and token management. Compaction strategies, progressive disclosure, structured note-taking via AgentDB. Triggers: tokens, compaction, memory, handoff, summarize, context window.

Frontend aesthetics and UI implementation. Break generic AI aesthetic patterns. Create distinctive, surprising interfaces. Supports mood variants that guide aesthetic direction without constraining execution. Triggers: design, frontend, ui, styling, css, visual, theme, component, layout, abyss, spatial, verdant, substrate, ember, arctic, void, patina, signal.

End-to-end testing with Playwright. Page Object Model, flaky test strategies, CI integration. Triggers: e2e, playwright, browser, end-to-end, integration-test, ui-test.

Eval-Driven Development (EDD) for AI workflows. pass@k metrics, capability evals, regression evals. Triggers: eval, edd, pass@k, capability, regression, benchmark.

Scientific method for development rules. Every rule is a hypothesis. Nothing proven until tested. Triggers: experiment, hypothesis, prove, test rule, validate methodology, scientific, evidence.

Multi-agent orchestration patterns. AgentDB as structured briefing, 4 fault tolerance layers (retry, fallback, classification, checkpointing), context transfer protocols. Triggers: orchestrate, coordinate, agents, parallel, spawn, contract, tier 2, tier 3.

Performance optimization and profiling. Measure before optimizing, identify bottlenecks, avoid premature optimization. Triggers: performance, speed, slow, optimize, latency, throughput, profiling, benchmark.

AI code quality checks. The Big 5: input validation, edge cases, error handling, duplication, complexity. Triggers: quality, big 5, ai code, review, validate.

Test-Driven Development workflow. Tests BEFORE code. Red-green-refactor cycle. Triggers: tdd, test-first, test-driven, red-green, coverage.
