Use when editing .csproj, .nuspec, Directory.Build.props, Directory.Build.targets, Directory.Packages.props, the Cake build (build.cake, build.ps1, build.sh), or GitHub Actions workflows. Covers central package management, MinVer-driven versioning, the props-vs-targets split, and nuspec/csproj consistency.
Use when writing or modifying C# method bodies, type declarations, or non-trivial logic in NUnit source. Covers NUnit's taste-and-judgment conventions — exception construction, simplification, naming intent, StringComparison, non-null check form, and var usage — that aren't already caught at build time.
Use when modifying hot paths in NUnit — constraint evaluation, equality comparison, value formatting, reflection-based dispatch, collection inspection, or anything that runs once per assertion or per test discovery. Covers allocation patterns, reflection caching, and how the team expects performance claims to be…
Design, change, or review an HTTP/JSON API surface — endpoints, request/response shapes, authentication and authorization, pagination, idempotency, rate limits, versioning, and deprecations. Use when adding or modifying an HTTP endpoint, reviewing an OpenAPI spec or HTTP route diff, or deciding whether an HTTP API…
Evidence-first development — surround the implementation with an executable spec and a gauntlet of constraints (tests, types, coverage, mutation) so line-by-line review becomes optional. Use when the user explicitly asks for high-assurance or evidence-first work ("reliable", "TDD", "prove it works", "I won't read the…
Design or review infrastructure, deployment, CI/CD, Docker, Kubernetes, health checks, rollback, feature flags, production readiness, and mobile release workflows. Use for DevOps, platform, container, pipeline, or release tasks.
Creates detailed, sectionized, TDD-oriented implementation plans through research, stakeholder interviews, and multi-LLM review. Use when planning features that need thorough pre-implementation analysis.
Reference Maven POM fragments for the full harness — Spotless, Checkstyle, SpotBugs, Error Prone, JaCoCo, PIT, OpenAPI generator + diff, OWASP dependency check, Surefire/Failsafe. Use when wiring the harness into a new project or upgrading a brownfield POM.
Spring Boot 4 / JVM performance work — measure first, then fix. Profiling (async-profiler, JFR, JMH), Micrometer, common Spring antipatterns (N+1, unbounded lists, HikariCP sizing, virtual-thread pinning), caching, GC, and SLO-driven work. Used by /plan for risk callouts and by /review to flag perf regressions.
Spring Framework 7 / Spring Boot 4 idioms and defaults. Use when writing or reviewing controllers, services, configuration, HTTP clients, async/virtual-thread code, or anything touching Spring's programming model.
Configure Better Auth server and client, set up database adapters, manage sessions, add plugins, and handle environment variables. Use when users mention Better Auth, betterauth, auth.ts, or need to set up TypeScript authentication with email/password, OAuth, or plugin configuration.
Configure rate limiting, manage auth secrets, set up CSRF protection, define trusted origins, secure sessions and cookies, encrypt OAuth tokens, track IP addresses, and implement audit logging for Better Auth. Use when users need to secure their auth setup, prevent brute force attacks, or harden a Better Auth…
A workflow for recording workspace changes in Git, the version-control system used to track code history. It includes locking, coordination checks, commit conventions, and cleanup if the process stops.
Use to develop a feature or bug fix end-to-end through a TDD git-worktree workflow — interactively (developer-led) or unattended (autonomous-mode, driven by the dispatcher). Triggers on phrases like "implement issue #N", "fix this bug", "add a feature", "create a worktree", "write test cases", "push and open a PR"…
Use to perform an end-to-end PR review and reach an approve/request-changes verdict — including verifying acceptance criteria, running E2E tests via browser automation, resolving merge conflicts, and (when verdict passes) merging the PR. Triggers on phrases like "review this PR", "decide whether to approve and merge"…
Use when the user asks to create a GitHub issue, file a bug, request a feature, open a tracking issue, or break a feature into multiple sub-issues. Guides interactive issue drafting with structured templates, workspace-change attachment, dependency linking, and the optional autonomous label for the automated dev…
Manages persistent task memory using Beads. Automatically invoked when discussing task tracking, long-running projects, session persistence, or context preservation across sessions. Handles syncing between tasks.md and Beads.
Provides project coding standards and architectural principles on-demand. Automatically invoked when implementing features, writing code, or making technical decisions. Reads constitution.md to ensure all code aligns with project principles.
