Build, repair, or review Maple dashboard widgets via the MCP. Triggers on phrases like 'create_dashboard', 'add_dashboard_widget', 'update_dashboard_widget', 'dashboard widget JSON', 'QueryDraft', 'trace dashboard widget', 'Invalid input for getQueryBuilderTimeseries', or any session that submits raw widget JSON to the maple MCP. Covers the source-discriminated QueryDraft shape, the custom whereClause grammar, valid aggregations per data source, groupBy prefix conventions, the stat-widget `reduceToValue` transform, hiding auxiliary series on formula charts, and the verification step (MCP success ≠ query success).

Maple's OpenTelemetry conventions — custom span attribute keys (`maple.*` vendor namespace, `query.context`, `db.statement.*`, `result.*`, `cache.*`, `tenant.*`), Title Case status codes (`Ok`/`Error`/`Unset`), resource attribute dual-emit (`deployment.environment` + `deployment.environment.name`), span kinds, Tinybird MV pre-extracted columns, loop-prevention filters, and sampling. Use whenever writing or reviewing instrumentation code in any language (TypeScript, Rust, Python) in this repo — adding `setAttribute`/`setAttributes`/`record`/`#[instrument(fields(...))]` calls, setting span status, configuring an OTLP exporter, defining a new resource attribute, or wiring a new query through `WarehouseQueryService.sqlQuery()`.

.NET / C# OpenTelemetry style for Maple: OpenTelemetry.Extensions.Hosting + OTLP HTTP exporter, ActivitySource for spans, ILogger bridging via OpenTelemetryLoggerProvider, inline endpoint + ingest key.

Effect-TS OpenTelemetry style for Maple via @maple-dev/effect-sdk: Maple.layer() bootstrap, Effect.withSpan / Effect.annotateCurrentSpan call sites, Effect.log for trace-correlated logging, server / browser / Cloudflare entry points.

Go OpenTelemetry style for Maple: go.opentelemetry.io/otel SDK with otlptracehttp / otlploghttp / otlpmetrichttp exporters, inline endpoint + ingest key, semconv resource attributes including vcs.repository.url.full.

Java OpenTelemetry style for Maple: zero-code Java agent or manual SDK with OTLP HTTP exporters, inline endpoint + ingest key, semconv resource attributes, OTLP-bridged Logback / SLF4J logs.

Kotlin (Ktor, Spring Boot) OpenTelemetry style for Maple: zero-code Java agent or manual SDK with OTLP HTTP exporters, inline endpoint + ingest key, semconv resource attributes, OTLP-bridged logs.

Next.js / Vercel OpenTelemetry style for Maple: instrumentation.ts, @vercel/otel bootstrap, native @opentelemetry/api call sites, inline endpoint + ingest key, no raw NodeSDK replacement.

This skill should be used when the user asks to "review effect v4 code", "effect v4 review", "review my effect 4 code", "check effect v4 patterns", "run effect v4 review", "audit the effect codebase", or wants a comprehensive code review of an Effect v4 (effect-smol / the 4.0 beta line) codebase against v4 conventions for Context.Service, Layer composition, Schema.TaggedErrorClass, the flattened Cause, Effect.fn, branded Schema types, observability, effect-atom, and test coverage. Supports reviewing a PR/branch diff or the whole repository. For Effect v3 codebases, use the effect-review skill instead.

Rework a change as if the intended UX and architecture existed from day one, deleting compatibility cruft and accidental complexity. Use when the user asks to remove tech debt, clean up a patch, or rework a change to its intended end state.

This skill should be used when the user asks to "review code", "review my changes", "check effect patterns", "run effect review", "effect review", "review for effect best practices", or wants a comprehensive code review against Effect-TS conventions, branded types, observability, error handling, test coverage, and UI quality.

Enforces Effect-TS patterns for services, errors, layers, and atoms. Use when writing code with Effect.Service, Schema.TaggedError, Layer composition, or effect-atom React components.
