Backend Development

Backend Development covers API design, database integration, microservices, and backend security patterns for building server-side applications. Use it when designing APIs, implementing server logic, authentication, or authorization.

CI Loop

CI Loop polls required pull request checks, classifies mechanical vs semantic failures, and applies safe automated patches up to three iterations before escalating to the user. Use it after creating a PR with /moai sync to monitor CI and auto-fix failures.

Claude Code Authoring Kit

Claude Code Authoring Kit is a comprehensive reference for creating and configuring Claude Code extensions, covering Skills, sub-agents, plugins, slash commands, hooks, memory, settings, sandboxing, headless mode, and advanced agent patterns.

Cross-Model Audit Convergence

Cross-Model Audit Convergence documents how plan-auditor and sync-auditor agents invoke the audit_multi MCP tool to run code review across codex and GLM backends in parallel, converge their verdicts with Claude, and fold per-backend verdicts and a disagreement flag into audit output. Use it when a project sets audit_model to multi.

Database Domain Specialist

Database Domain Specialist provides patterns and implementations for PostgreSQL, MongoDB, Redis, Oracle, and cloud databases. Use it for schema design, query optimization, indexing, data modeling, and cloud database selection.

Docs i18n Rules

Docs i18n Rules defines hard internationalization rules for the moai-adk-go README and docs-site, covering canonical locale chains, simultaneous 4-locale updates, Mermaid TD-only diagrams, no-emoji in body text, emphasis-marker spacing, URL blacklist, version SSOT, and immutable Vercel binding. Loaded first by documentation specialists before any edit.

Benchmark

Benchmark measures performance baselines, detects regressions before and after PRs, and compares stack alternatives for pages, APIs, and builds.

Benchmark Optimization Loop

Benchmark Optimization Loop turns vague performance goals into a bounded, measured optimization process. Use it when asked to make something faster, benchmark latency/throughput/cost, or choose the best implementation by repeated measured tests.

API Design Patterns

API Design Patterns provides conventions and best practices for designing consistent REST APIs. Use it when creating endpoints, reviewing contracts, handling pagination, error responses, status codes, filtering, or versioning.
