FusionalyAUse when the user asks about website analytics, traffic, visitors, page views, referrers, conversions, goals, or mentions "fusionaly". Answers from a self-hosted Fusionaly instance through its MCP tools (or its SQL API), in plain English with numbers.databasesgosqlVotes: 0GitHub stars: 13
Sqlite Durable Agent StateADesign durable local SQLite state for multi-agent developer tooling that survives package upgrades, concurrent writers, and crashes: canonical env-pinned paths, WAL/busy_timeout discipline, idempotent verified migrations, and safe writer topology. Use when a daemon, CLI, or agent fleet needs a persistent local DB, when reviewing a schema/path change before it ships, or when diagnosing an already-fragmented multi-.db mess. NOT for relational schema/query design (use daemon-development for the ...databasesrustgoVotes: 0GitHub stars: 2

Supabase Postgres Best PracticesAPostgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pg_cron, pgmq), vector/semantic search (pgvector), and restoring dumps (pg_restore) or im...databasesgosqlVotes: 0GitHub stars: 2,705
Swoole ExpertADeep reference for writing production Swoole PHP code. Covers the long-running process mental model (object lifetimes, what breaks vs php-fpm, per-request state via Coroutine::getContext), runtime hook flags (what's hookable year-to-year, what isn't), parent/child priority gotcha, Channel/WaitGroup/Barrier/defer patterns, server canonical skeleton (SWOOLE_BASE default since 5.0, dispatch modes, graceful reload rules), connection pooling (try/finally + defer, Channel-as-pool), the full pitfall...databasesgophpVotes: 0GitHub stars: 2
Database DesignADatabase schema design, optimization, and migration patterns for PostgreSQL, MySQL, and NoSQL databases. Use for designing schemas, writing migrations, or optimizing queries.databasessqldatabaseVotes: 0GitHub stars: 2
Prd InitAUse when the user wants to set up pwdev-prd in a project — 'inicializar o pwdev-prd', 'init prd', 'configurar PRDs' — creating the .planning/prds/ workspace and choosing language and the optional SQLite audit trail. Do NOT use to write a PRD (prd-create).databasesgobashVotes: 0GitHub stars: 3
Prd AuditAUse when the user asks about the pwdev-prd audit trail — 'auditoria do prd', 'eventos', 'decisões registradas', 'audit report', 'exportar relatório de auditoria' — querying the shared SQLite database read-only (summary, events, decisions, artifacts, stats, export, query).databasespythongoVotes: 0GitHub stars: 3
Feat AuditAUse when the user wants to query the local pwdev audit trail — 'ver auditoria', 'relatório de auditoria', 'audit stats', 'exportar auditoria em PDF' — summary, events, decisions, artifacts, statistics, a Markdown/PDF export or a custom read-only SELECT. Do NOT use to enable the audit (feat-init) or for plan status (feat-status).databasespythonsqlVotes: 0GitHub stars: 3
Zero Downtime Database MigrationAUse when changing schema on a live production database without dropping traffic, doing expand/contract migrations, backfilling new columns on million-plus-row tables, dual-writing across schemas, renaming a hot column, splitting a table, or adding a foreign key to a big table. Triggers: ALTER TABLE locks the world, "must be removed in a separate deploy", expand-contract-cleanup phases, NOT NULL on populated column, foreign-key add on big table, dropping a column still read by old replicas, lo...databasesgorubyVotes: 0GitHub stars: 2
Supabase AdminASupabase administration, RLS policies, migrations, and schema design. Use for database architecture, Row Level Security, performance tuning, auth integration. Activate on "Supabase", "RLS", "migration", "policy", "schema", "auth.uid()". NOT for Supabase Auth UI configuration (use dashboard), edge functions (use cloudflare-worker-dev), or general SQL without Supabase context.databasesjavascriptgoVotes: 0GitHub stars: 2

Postgres Connection PoolingAChoosing a Postgres connection pool mode that matches your workload — pgBouncer session/transaction/statement modes, the prepared-statement story (pgBouncer 1.21+), Supabase Supavisor's port-per-mode pattern (5432 vs 6543), AWS RDS Proxy pinning triggers, and `pg_stat_activity` diagnostics. Grounded in pgbouncer.org, supabase.com, AWS docs, and PostgreSQL docs. NOT for ORM-specific connection config, Postgres replication/read-replica design, non-Postgres poolers (PgPool for MySQL, ProxySQL), ...databasespythongoVotes: 0GitHub stars: 2
Outbox Pattern ImplementationAUse when you need to publish a message to Kafka / RabbitMQ / SNS atomically with a database commit, when fixing the dual-write hazard between DB and broker, deciding between polling-publisher and CDC (Debezium) relay, designing the outbox schema, handling at-least-once / idempotency on the consumer, or pruning a high-volume outbox table. Triggers: dual write, "we updated the DB but the event never published", outbox/inbox pattern, Debezium connector, EventRouter SMT, aggregate_type / aggregat...databasesrustgoVotes: 0GitHub stars: 2
Multi Agent CoordinationACoordinate multiple AI agents working on the same codebase or project simultaneously.

Activate on: "multi-agent", "parallel agents", "agent coordination", "worktree isolation", "concurrent agents", "file locking agents", "agent conflict...databasesgobashVotes: 0GitHub stars: 2
Duckdb AnalyticsAUse when running analytical SQL over Parquet/CSV/JSON without a warehouse, replacing pandas for data wrangling, joining S3 data in-place, building local data marts, or embedding OLAP into an app. Triggers: read_parquet/read_csv setup, partitioned dataset queries, hive partitioning, glob patterns for S3, COPY TO export, attach Postgres/MySQL, UDFs in Python/R, MotherDuck cloud sync, columnar performance vs row stores. NOT for OLTP workloads (concurrent writes), distributed analytics at petabyt...databasespythongoVotes: 0GitHub stars: 2
Distributed Tracing W3c ContextAImplementing distributed tracing with W3C Trace Context — the byte-precise `traceparent` and `tracestate` header formats, OpenTelemetry's W3CTraceContextPropagator as the modern default (replacing X-B3-* and X-Datadog-*), head vs tail sampling, and HTTP→SQL trace propagation via sqlcommenter. Grounded in the W3C REC and OpenTelemetry specs. NOT for OTel metrics/logs pipelines, vendor backend setup (Datadog/Honeycomb/Jaeger/Tempo), or browser RUM tracing.databasesgobashVotes: 0GitHub stars: 2
Db Retention And CompactionADesigns and audits data retention and file compaction for an embedded SQLite datastore in a long-lived service — a unified retention registry (one declared policy per table), TTL / absolute-age / row-count-cap policies, a fail-loud coverage guard, WAL/checkpoint tuning, and auto_vacuum/incremental-vacuum so pruning actually shrinks the file. Use when a SQLite DB grows unbounded, a table has an index but no DELETE, a pruned DB never shrinks on disk, metrics are stored as raw events forever, or...databasespythongoVotes: 0GitHub stars: 2
D1 And Supabase MigrationsAUse when applying Cloudflare D1 migrations, fighting Supabase migration history vs SQL execution, choosing direct psql over CLI, designing idempotent migrations, debugging schema drift between local and remote, or recovering after a half-applied migration. Triggers: supabase migration repair instructions appearing, table missing after "applied" status, "Tenant or user not found" when running psql, --remote vs --local D1 confusion, NOT NULL on a populated column, foreign key constraint failure...databasesrustgoVotes: 0GitHub stars: 2
